Federal Drug Law and the State Legalization Question

Federal drug law and state legalization law answered the same conduct in opposite ways on September 1, 2018, and the comparison between the two regimes confused readers who treated either regime as the whole law. A state statute in Colorado or Washington permitted licensed cultivation and retail sale under state conditions. A federal statute, the Controlled Substances Act of 1970, classified marijuana in Schedule I and prohibited manufacture, distribution, dispensing, and possession in every state. Neither statement cancelled the other. A license documented compliance with one sovereign and exposure under the law of the other, and a registered patient held a state authorization that supplied no federal defense. The comparison therefore began with a separation that ordinary political language obscured, because legalization described a change in state law and prohibition described a rule of federal law, and both descriptions were accurate at the same time.

The question reached several audiences in different forms, and each audience received a characteristic wrong answer. A student in a federalism course received the answer that the Supremacy Clause ended the inquiry, as if state repeal were a state attempt to override Congress. A journalist on a deadline received the answer that defiance explained the state programs, as if a legislature repealing a state penalty were a legislature nullifying a federal one. A business owner weighing a license application received the answer that a state license settled legality, as if one sovereign could issue immunity against the criminal code of another. An official administering a state program received the answer that federal enforcement policy settled the legal position, as if a memorandum from the Department of Justice had amended a statute. Each answer collapsed two legal systems into one, and each collapse produced a false prediction about arrest, banking, taxation, firearms, immigration, employment, housing, or research.

The doctrinal answer rested on a distinction between regulating private conduct and commanding a state. Congress regulated private conduct directly through the Controlled Substances Act, and the Supreme Court sustained that regulation against a Commerce Clause challenge in Gonzales v. Raich in 2005. Congress held no parallel power to dictate the contents of a state criminal code. In New York v. United States in 1992, in Printz v. United States in 1997, and in Murphy v. NCAA in 2018, the Supreme Court held that Congress could not compel a state legislature to enact or retain a prohibition and could not conscript state officers to enforce a federal program. Section 903 of Title 21 reinforced the division by disclaiming field preemption and by requiring a positive conflict before a provision of the federal drug subchapter displaced state law. A state repeal created no such conflict, because refraining from marijuana conduct satisfied both sovereigns at once.

Doctrine alone, however, described only the outer boundaries of the arrangement in force in 2018. Between those boundaries, a second regime governed daily practice, assembled from an appropriations rider that Congress first enacted in December 2014 and from enforcement memoranda that the Department of Justice issued in 2009 and 2013 and that Attorney General Sessions rescinded on January 4, 2018. The rider barred the Department from spending appropriated funds to prevent listed states from implementing medical marijuana laws, and the Ninth Circuit enforced that bar for individuals in strict compliance with state law in United States v. McIntosh in 2016. The memoranda directed federal prosecutors toward defined priorities and away from state compliant conduct, without creating rights that a defendant could enforce in court. A recreational program stood outside the rider altogether. Practice therefore depended on fiscal language renewed year by year and on discretion revocable by a successor official, rather than on any amendment to the prohibition itself.

A third layer completed the comparison, because federal law reached state authorized conduct through regimes that required no drug prosecution at all. Banks applied money laundering statutes and Bank Secrecy Act duties to accounts holding marijuana proceeds. The Internal Revenue Service applied section 280E of the Internal Revenue Code to deny ordinary business deductions to a licensed retailer. Immigration officers, firearms licensees, federal employers, housing authorities, and research regulators each applied a federal definition that treated marijuana use or distribution as unlawful regardless of state authorization. A verdict on the comparison had to account for all three layers at once: a doctrine that permitted coexistence, a practice that made coexistence conditional, and a set of collateral regimes that narrowed the practical value of a state license even in places where no federal prosecutor filed a charge.

Why a state may repeal its own prohibition

A state legislature votes to repeal a criminal prohibition that the legislature enacted, and the conduct described in the repealed statute remains forbidden by an Act of Congress. Federal law forbids the manufacture, distribution, and possession of marijuana under the Controlled Substances Act, and a state statute that permits licensed cultivation or retail sale appears to authorize the same conduct that federal law punishes. State legalization statutes enacted in Colorado in 2012, in Washington in 2012, and in other states through August 2018 therefore raised a question that reached beyond drug policy. The question concerned which government held authority over the contents of a state criminal code.

The resolution, as the Supreme Court articulated the doctrine between 1992 and 2018, turned on a distinction that the apparent conflict obscured. A state that repeals a prohibition governs only the law of that state. Repeal removes a penalty that state officers imposed under state authority, and repeal creates no penalty, duty, or defense under federal law. The federal prohibition continues to operate against private conduct through federal investigation, federal prosecution, and federal courts, and a state license settles the position under state law alone. Legalization, understood in that precise sense, is not defiance of federal law and is not nullification. A state exercises a reserved power when the state decides what the state code forbids and what the state code permits, and the federal government retains the whole of the enforcement power that Congress conferred on federal officers.

That arrangement follows from the design that the Constitution established. The Constitution granted Congress enumerated powers and reserved the powers not delegated to the states or to the people, a reservation that the Tenth Amendment stated in text. A state legislature draws authority from a state constitution and from the people of the state, and the legislature does not serve as an administrative branch of Congress. From that premise, the Supreme Court derived a limit that later opinions named the anticommandeering doctrine. Congress may regulate private conduct directly, may offer states incentives to adopt federal policy, and may preempt state law through a valid federal regulation of private conduct, but Congress may not compel a state to enact a federal program and may not conscript state officers to administer a federal program.

The legislative command rejected in New York v. United States

The Supreme Court gave the doctrine its modern legislative form in New York v. United States, 505 U.S. 144 (1992). The case concerned the Low-Level Radioactive Waste Policy Amendments Act of 1985, a federal statute that addressed disposal of low level radioactive waste through incentives directed at the states. The Court upheld incentives that operated through money and through access to disposal facilities, because each incentive left a state with a choice without dictating the content of state law. The third provision, known as the take title provision, crossed that line. Under that provision, a state that failed to provide for disposal of waste generated within state boundaries by a date fixed in the federal statute was required, on the request of a waste generator, to take title to the waste and to assume liability for damages that resulted from the failure to act.

Justice O’Connor, writing for the majority in New York, held that the take title provision exceeded the authority of Congress. Congress may not simply commandeer the legislative processes of the states by directly compelling the states to enact and enforce a federal regulatory program, the majority reasoned, because a state legislature compelled in that manner ceases to legislate as an independent sovereign. The majority distinguished encouragement from compulsion. Conditional spending presents a state with reasons to adopt a federal policy, and a state that accepts the condition remains answerable to state voters for the adoption. A direct order removes the decision from the state entirely, and the resulting statute expresses the judgment of Congress rather than the judgment of the state.

The executive command rejected in Printz v. United States

In Printz v. United States, 521 U.S. 898 (1997), the Supreme Court addressed interim provisions of the Brady Handgun Violence Prevention Act. The Brady Act directed the Attorney General to establish a national instant background check system for firearms purchases, and the Act imposed duties on state and local officers during the period before the federal system became operational. Under the interim provisions, the chief law enforcement officer of a locality was required to receive information from firearms dealers, to make a reasonable effort to determine whether a proposed sale would violate the law, and to perform the related tasks that the background check demanded. Sheriffs from Montana and Arizona challenged the duty.

Justice Scalia, writing for the majority in Printz, held that the interim background check duty was unconstitutional. The federal government may neither issue directives requiring the states to address particular problems nor command the officers of the states to administer or enforce a federal regulatory program, the majority stated, and the Brady Act provisions failed under that rule. The reasoning drew on the structure of the Constitution, on historical practice, and on the precedent that New York had established. Conscription blurred the lines of accountability, because a citizen injured by an erroneous background check would confront a local sheriff performing a duty that a federal statute had imposed, and neither sovereign would bear complete responsibility. Conscription also transferred the cost of a federal program to state budgets and state personnel.

Read together, New York and Printz established two halves of a single rule. Congress may not order a state legislature to write federal policy into state law, and Congress may not order a state executive to carry federal policy into effect. The rule did not diminish the power of Congress over private conduct, and a federal objective, however valid under an enumerated power, had to be pursued through federal institutions or through voluntary state cooperation. A distinct question persisted beneath the marijuana litigation of the period after 2012, concerning a federal statute that forbade a state legislature to repeal or modify a prohibition that the state had enacted. The Supreme Court answered that question in 2018.

Can Congress force a state to keep marijuana illegal?

No. In Murphy v. NCAA, decided in 2018, the Supreme Court held that Congress may not order a state legislature to maintain a prohibition. Congress may regulate private conduct directly and enforce federal law with federal officers, but a state may repeal its own ban.

The direct order condemned in Murphy v. NCAA

Murphy v. NCAA, 584 U.S. 453 (2018), decided on May 14, 2018, concerned the Professional and Amateur Sports Protection Act, a federal statute that Congress had enacted in 1992 to restrict sports wagering outside a small set of states with preexisting schemes. The provision at the center of Murphy made the authorization of sports wagering by a state unlawful, and the provision directed at states operated on the lawmaking act itself rather than creating a general federal crime of operating a wagering scheme. New Jersey, after voters approved a constitutional amendment concerning sports wagering, enacted legislation that repealed state prohibitions at casinos and racetracks in a manner that the lower federal courts treated as an authorization forbidden by the federal statute.

Justice Alito, writing for the majority in Murphy, held that the distinction failed. The provision forbidding state authorization violated the anticommandeering rule, the majority held, because the provision issued a direct order to state legislatures. A federal law that dictates what a state legislature may and may not do places the state legislature under the direct control of Congress, in the formulation that the majority adopted, and such control reproduced the defect that New York had condemned. An order requiring a legislature to enact a prohibition and an order forbidding a legislature to repeal a prohibition both removed the subject from legislative discretion. The anticommandeering rule, the majority reasoned, admits no distinction between compelling a state to enact legislation and compelling a state to retain legislation, because in each case the content of state law follows a federal instruction rather than a state decision.

The reasoning in Murphy also clarified the boundary between commandeering and preemption. Preemption rests on the Supremacy Clause and operates when a federal law regulates the conduct of private actors and a state law conflicts with that regulation. A federal statute that regulates the states as states stands on different ground, because such a statute governs no private conduct in the relevant provision, and the only conduct governed is the conduct of a legislature in session. Congress acts within the preemption power when Congress writes a rule for private parties. Congress exceeds the anticommandeering limit when Congress writes a rule for legislatures and the rule determines whether a state prohibition exists. The majority in Murphy treated that difference as decisive.

Repeal and licensing as changes to state law alone

Application of the doctrine to marijuana legalization begins with an exact description of what a legalization statute does. A repeal statute removes offenses, penalties, and enforcement authority that prior state law had created. A licensing statute establishes a state regime under which state agencies issue permits, collect state taxes, inspect premises under state standards, and impose state sanctions for violations of state conditions. Each element operates within state law, and a state license makes no declaration about federal law. Federal agents remained free, throughout the period covered by the legalization statutes enacted between 2012 and August 2018, to investigate conduct that state law permitted, and federal prosecutors retained discretion to bring charges under the Controlled Substances Act for the same conduct.

No state officer is required, by the fact of legalization, to enforce the federal ban, and Congress cannot order the state to keep its ban on the books. A state may direct state resources toward the priorities that state law establishes, and a state may decline to spend state funds or personnel hours on enforcement of a federal prohibition that the state has chosen not to mirror in the state code. Congress cannot order state police to investigate violations of the federal schedules as a federal duty, and Congress cannot convert a state licensing agency into an arm of federal drug enforcement by statute. Congress may fund joint task forces and may offer grants with lawful conditions. The Constitution, as interpreted in New York, in Printz, and in Murphy, leaves the decision about state assistance to the state.

The Controlled Substances Act itself fits the pattern that Murphy required. The Act regulates private conduct, prohibiting the manufacture, distribution, dispensing, and possession of scheduled substances, and authorizing federal officers to investigate and federal prosecutors to charge violations. No provision of the Act orders a state legislature to enact a parallel prohibition, and no provision assigns state officers a duty to enforce the federal schedules. Under the framework that Murphy stated, the absence of such provisions was constitutionally necessary rather than merely prudent. A hypothetical amendment that required each state to maintain a criminal prohibition on marijuana, or that forbade a state to repeal a prohibition on marijuana, would dictate the content of state law and would fall, under Murphy, as a direct order to state legislatures.

The limited preemption written into section 903

An argument against that account proceeds through preemption. Under the Supremacy Clause, a valid federal law displaces a conflicting state law, and a state statute that permits conduct that federal law forbids appears to conflict in direct terms. The argument gains force from the breadth of the Controlled Substances Act, which the Supreme Court sustained against a Commerce Clause challenge in Gonzales v. Raich, 545 U.S. 1 (2005), a decision that held that Congress could regulate intrastate cultivation and possession of marijuana for personal medical use under the commerce power. Raich settled the reach of federal power over private conduct. Raich did not settle the distinct question whether Congress could require a state to prohibit the same conduct under state law.

Congress addressed the relation between the Controlled Substances Act and state law in 21 U.S.C. 903, a provision enacted as part of the original statute in 1970. Section 903 provides that no provision of the subchapter shall be construed as indicating an intent on the part of Congress to occupy the field in which the provision operates, including criminal penalties, to the exclusion of state law on the same subject matter, unless a positive conflict exists between the federal provision and state law so that the two cannot consistently stand together. The text rejects field preemption in express terms, and the disclaimer preserved the traditional authority of states to legislate on health, safety, and criminal punishment in the same field. Under section 903, displacement requires a positive conflict, a formulation that requires impossibility of dual compliance or a state law that mandates conduct that federal law forbids.

A state decision to decline punishment does not satisfy that standard, because a permission under one legal system is not a command that binds another. A person in a legalization state who possesses marijuana in compliance with state law violates federal law, and federal law attaches federal consequences to the violation. Dual compliance remains entirely possible, because a person complies with both sovereigns by refraining from the conduct, and neither statute orders any person to possess, cultivate, or sell marijuana. A state licensing statute imposes affirmative state duties concerning taxation, testing, labeling, and recordkeeping, and compliance with those duties does not require a violation of federal law in the sense that section 903 describes. The conflict lies between a federal policy of prohibition and a state policy of regulated permission, and section 903, by the terms that Congress selected in 1970, treats a conflict of policy as insufficient.

Both sovereigns may prohibit the same conduct, and a state prohibition enacted alongside the federal prohibition raises no preemption difficulty, because the state law reinforces the federal command to private parties. Either sovereign may decline to prohibit, and a federal decision to remove a substance from the schedules would leave a state prohibition fully operative under state law, just as a state repeal leaves the federal prohibition fully operative under federal law. Neither sovereign can force the other to prohibit. Congress cannot compel a state prohibition under Murphy, and a state cannot compel Congress to repeal a federal prohibition. Each sovereign answers to a separate electorate for the choice, and the accountability that New York identified as a central purpose of the anticommandeering rule attaches to each choice.

Structure as the source of legality

The consequence of the doctrine reframes the ordinary description of state legalization. Legalization statutes enacted between 2012 and August 2018 were lawful exercises of state power not because the federal prohibition lacked force, and not because federal enforcement agencies exercised restraint, and not because any court held marijuana regulation to lie outside the commerce power of Congress. Raich foreclosed the last of those grounds in 2005, and the guidance issued by the Department of Justice in August 2013 stated enforcement priorities as a matter of discretion rather than as a concession about statutory authority. Legalization was lawful because the federal structure forbids Congress from drafting state legislatures into keeping the federal ban in force. The power to repeal a state prohibition belonged to the same sovereign that had enacted the prohibition, and the decisions in New York, in Printz, and in Murphy denied Congress the instruments necessary to override that allocation.

That allocation of power explains only half of the comparison, because a state repeal leaves a federal prohibition with independent force and a separate enforcement apparatus.

What Federal Law Forbids

The Controlled Substances Act Baseline

A state legalization measure operates on state law alone. The measure repeals or narrows state criminal prohibitions and creates a state licensing system. Federal law occupies a separate track, and no state enactment amends a federal statute. On September 1, 2018, the federal track for marijuana rested on a classification decision made at the creation of the modern federal drug code. The Controlled Substances Act of 1970 presented the prohibitions, the schedules, and the penalty provisions as a single statutory scheme rather than as isolated rules.

Section 812 of Title 21 of the United States Code placed marijuana in Schedule I, the most restrictive of the five schedules established by the Controlled Substances Act. The Schedule I criteria in section 812(b)(1) required a high potential for abuse, no accepted medical use, and a lack of accepted safety for use under medical supervision. Placement in Schedule I carried consequences beyond a label, because a Schedule I substance had no recognized federal pathway for ordinary medical prescribing. Petitions to move marijuana to a less restrictive schedule had been denied across the decades after 1970, leaving the placement intact through August 2018.

The operative prohibitions appeared in sections 841 and 844 of Title 21. Section 841(a) made it unlawful for any person knowingly or intentionally to manufacture, distribute, or dispense a controlled substance, or to possess a controlled substance with intent to manufacture, distribute, or dispense it. Section 844 addressed simple possession and made knowing or intentional possession of a controlled substance a federal offense unless the possession rested on a valid prescription or another authorization recognized by the federal statute itself. Neither provision contained an exception for conduct licensed by a state or conducted entirely within a single state, and the text drew no distinction between a commercial grower and a patient cultivating plants at home.

Penalties under section 841 scaled with the quantity of marijuana involved and with the role and record of the person charged. Section 841(b)(1) set a mandatory minimum of five years and a maximum of forty years for a first offense involving one hundred kilograms or more, or one hundred or more plants, and a minimum of ten years and a maximum of life for one thousand kilograms or more, or one thousand or more plants. A first offense involving less than fifty kilograms carried a maximum term of five years under section 841(b)(4), and prior felony drug convictions raised the minimum and maximum at each tier. Simple possession under section 844 carried a maximum of one year for a first offense. Federal exposure therefore varied by weight, plant count, intent, and record, while the underlying unlawfulness did not vary at all.

Commerce Clause Reach From Wheat to Marijuana

The constitutional authority asserted for the federal prohibition rested principally on the power of Congress to regulate commerce among the several states. The breadth of that power determined whether a federal ban could reach marijuana that was grown at home, consumed at home, and never sold or transported across a state line. The leading precedent arrived in Wickard v. Filburn, 317 U.S. 111 (1942), a case concerning wheat rather than any controlled substance. Roscoe Filburn, an Ohio farmer, grew wheat in excess of the allotment set under the Agricultural Adjustment Act of 1938, and part of the excess was consumed on the farm itself rather than sold. The Supreme Court upheld the federal penalty and reasoned that home consumed wheat competed with wheat offered in commerce, because a farmer who supplied a need from a personal crop made one fewer purchase in the open market.

The reasoning in Wickard rested on aggregation. Justice Robert Jackson, writing for the Court, treated the effect of a single farmer as an incomplete measure of the constitutional question. A contribution to demand that appeared trivial in isolation could, taken together with those of many others, exert a substantial influence on price and market conditions. Congress could therefore regulate a class of local activity when the class, in the aggregate, substantially affected interstate commerce, even though a particular instance involved no sale or shipment. Aggregation supplied the foundation on which the marijuana cases of the early twenty first century were later built.

Gonzales v. Raich, 545 U.S. 1 (2005), applied that foundation directly to state authorized medical marijuana. Angel Raich and Diane Monson used marijuana under California’s Compassionate Use Act of 1996, which California voters had adopted as Proposition 215. Monson cultivated her own plants at home, and federal agents destroyed six plants at her residence in August 2002. Raich and Monson sought a declaration that the Act, as applied to intrastate cultivation and possession for personal medical use, exceeded the commerce power of Congress. The Supreme Court rejected that claim by a vote of six to three on June 6, 2005. Justice John Paul Stevens wrote the opinion of the Court, and Justice Antonin Scalia concurred in the judgment on reasoning emphasizing the power of Congress to reach intrastate activity necessary to a comprehensive interstate scheme.

The majority in Raich identified marijuana as an economic commodity for which an interstate market existed, even though federal law prohibited that market. Congress, the opinion reasoned, had a rational basis for concluding that exempted homegrown marijuana would undercut the federal ban. Homegrown and interstate supply were fungible, officers faced difficulty distinguishing local from other marijuana, and diversion into the broader illicit market presented a risk Congress could rationally consider. Following Wickard, the Court assessed the class of activities rather than the plants of two plaintiffs, and that class, in the aggregate, bore a substantial effect on the interstate market the Act was written to eliminate. Because the Act regulated the national market through a closed system of schedules, registrations, and prohibitions, Congress could reach the local segment when an exemption would leave a gap in the federal scheme.

Justice Sandra Day O’Connor dissented, joined by Chief Justice William Rehnquist and, in substantial part, by Justice Clarence Thomas, who also wrote a separate dissent. Justice O’Connor grounded the dissent in federalism and argued that the Court had extended Wickard beyond economic regulation of a national market into an area of traditional state authority over health and criminal law. The dissent described the cultivation and possession at issue as noneconomic in character, warned that the majority reasoning lacked a limiting principle, and characterized the California program as an exercise of the police power the states retained. The disagreement concerned the unit of analysis: the majority measured the regulated class against the national market described by Congress, while the dissent measured individual conduct against the traditional subjects of state regulation.

Does a state marijuana license protect against federal prosecution?

No. A state license, registration card, or physician recommendation addresses state law only and provides no defense in a federal prosecution. Federal courts apply the Controlled Substances Act as written by Congress, and the Supreme Court rejected a medical necessity defense for distribution in 2001.

The leading decision on the defensive value of state authorization was United States v. Oakland Cannabis Buyers’ Cooperative, 532 U.S. 483 (2001). The Oakland Cannabis Buyers’ Cooperative distributed marijuana to qualified patients under the California medical program enacted in 1996, and the United States sought an injunction against that distribution under the Controlled Substances Act. The cooperative invoked the common law defense of medical necessity. The Supreme Court rejected the defense on May 14, 2001, in an opinion by Justice Clarence Thomas, without a dissent on the judgment and with Justice Stephen Breyer taking no part in the case. The opinion reasoned from the Schedule I classification itself: a necessity defense built on medical benefit would contradict the legislative judgment embodied in a schedule defined by the absence of an accepted medical use, apart from the narrow federally approved research context recognized by the Act.

Oakland resolved a question of statutory interpretation rather than constitutional power. The practical holding was nevertheless categorical: a state license established compliance with a state program, and a physician recommendation established approval under state law, but neither altered the elements of a federal offense, supplied a federal authorization of the kind section 844 recognized, or created a necessity defense. Evidence of state compliance entered a federal case, if at all, at charging discretion or sentencing rather than as a bar to conviction.

Raich and Oakland together produced the full federal position on September 1, 2018. Raich established the constitutional power to apply the prohibition to homegrown marijuana held under a state program, and Oakland established that the statute contained no medical necessity exception. A defendant therefore faced a prohibition constitutionally applicable under Raich and statutorily unqualified under Oakland, with no doctrinal opening for converting a state license into a federal defense. State measures adopted between 2001 and August 2018, including recreational legalization in Colorado and Washington in 2012, changed the state side of that position without changing either precedent.

The Boundary Drawn in Oregon

A single decision from the same period marked a limit concerning the authority of the Attorney General rather than the authority of Congress. In Gonzales v. Oregon, 546 U.S. 243 (2006), the Supreme Court considered an interpretive rule issued by Attorney General John Ashcroft in November 2001. The rule declared that assisting suicide was not a legitimate medical purpose under the Controlled Substances Act and that prescribing or dispensing controlled substances for that purpose violated federal law. Oregon had enacted the Death With Dignity Act in 1994, and voters had rejected a repeal measure in 1997, leaving a regime under which licensed physicians could prescribe lethal medication to terminally ill patients who satisfied detailed statutory safeguards. Oregon, joined by a physician, a pharmacist, and terminally ill patients, challenged the rule.

The Supreme Court held on January 17, 2006, by a vote of six to three, that the Controlled Substances Act did not authorize the Attorney General to declare the Oregon practice illegitimate and to treat participation in the state regime as a federal violation. Justice Anthony Kennedy wrote the opinion of the Court, and Chief Justice John Roberts and Justices Antonin Scalia and Clarence Thomas dissented. The majority found that Congress had given the Attorney General defined authority over registration, scheduling, and enforcement against illicit drug trafficking, while leaving regulation of medical practice principally to the states. The prescription provisions presupposed a legitimate medical purpose in the usual course of professional practice and did not delegate to a single executive officer the power to define general standards of medical practice for every locality. The absence of a clear congressional statement mattered as well, because displacing a state medical regime would have altered the federal and state balance in a field Congress had traditionally left to state regulation.

Gonzales v. Oregon did not disturb Raich. Raich sustained an act of Congress against a constitutional challenge, and the prohibition there appeared in the statutory text enacted in 1970. Gonzales v. Oregon rejected an act of the Attorney General resting on an asserted implication from a prescription regulation, with no corresponding statement in the statutory text. The distinction preserved a federalism conscious method of reading the Act: courts required Congress itself to speak when a federal rule displaced state medical regulation. For marijuana, the distinction offered no relief, because the Schedule I placement and the sections 841 and 844 offenses were the work of Congress rather than an interpretive extension by the Attorney General.

Sentencing, Forfeiture, and Limitations Exposure

The distance between state permission and federal prohibition was not a technicality. Federal prosecutors retained authority to present marijuana conduct to a federal grand jury even when the conduct complied in every respect with a state license, and Department of Justice enforcement memoranda, treated in full in the account of the practical regime that follows, altered neither that authority nor the Act and conferred no defense, leaving the charging authority under sections 841 and 844 untouched.

Sentencing exposure gave that charging authority its principal weight. A federal conviction carried the quantity based terms of section 841(b), including mandatory minimums of five and ten years at the one hundred and one thousand kilogram thresholds, or the corresponding plant counts, and a court lacked authority to go below a mandatory minimum except through mechanisms Congress provided, such as a government motion for substantial assistance or the safety valve criteria in section 3553(f) of Title 18 as those criteria stood in August 2018. The advisory Sentencing Guidelines calculated an offense level principally from drug quantity under section 2D1.1 of the Guidelines Manual. Simple possession under section 844 exposed a first offender to a maximum of one year, while distribution at commercial scale exposed participants to decades and, at the highest tier with qualifying prior convictions, to life. No provision of section 841 or section 3553 made state authorization an element, a cap, or a mandatory ground of departure.

Forfeiture exposure accompanied the criminal exposure and reached property rather than liberty. Section 853 of Title 21 provided for criminal forfeiture upon conviction, reaching proceeds of the offense and property used or intended to be used to facilitate it. Section 881 of Title 21 provided a separate civil forfeiture mechanism for property used to facilitate a violation and proceeds traceable to a violation. Real property used to cultivate marijuana, vehicles used to transport it, and currency received from its sale fell within the categories sections 853 and 881 described, and forfeiture under either provision turned on a federal violation rather than on a state license.

Time supplied the final element. Section 3282 of Title 18 required that an indictment for a noncapital federal offense be found within five years after the offense was committed, except as otherwise expressly provided by law. A federal marijuana offense committed in 2013 therefore remained subject to indictment into 2018 under section 3282, well beyond the January 2018 rescission of the Cole memorandum. Conduct undertaken in reliance on an earlier nonenforcement policy remained exposed for the balance of the five year period, and no doctrine treated such a policy as a repeal, a pardon, or a promise enforceable against a later prosecution brought within the period section 3282 allowed.

On September 1, 2018, Congress had placed marijuana in Schedule I in 1970, and the scheduling process established by the same Act had maintained that placement through every administrative review completed by August 2018, a history examined in the drug scheduling guide. Congress defined manufacture, distribution, and possession as federal offenses in sections 841 and 844, and the Supreme Court sustained those offenses against homegrown marijuana in Raich, rejected a medical necessity defense in Oakland Cannabis Buyers’ Cooperative, and confined only the Attorney General in Gonzales v. Oregon. A state measure rewrote the enacting state’s criminal code and relieved defined conduct of state penalties. The federal half of the legal position remained exactly where Congress had left it in the statute of 1970 and where the scheduling process had kept it through August 2018: a Schedule I prohibition, enforceable in every state, against conduct that any state remained free to permit under state law alone.

A prohibition on paper and a prohibition in operation diverged after 2009, and the instruments that created the divergence were fiscal and managerial rather than statutory.

The regime that actually governs: an appropriations rider and a stack of memoranda

On paper, the federal side of a comparison between federal drug law and state legalization law appeared complete. The Controlled Substances Act classified marijuana in Schedule I, and federal statutes prohibited its manufacture, distribution, dispensing, and possession outside narrow federal authorizations. Between 1996 and 2018, that statutory picture changed very little, while the practical picture changed a great deal through instruments that were not amendments to the drug statutes at all. The lived federal regime between 2009 and 2018 rested principally on two other kinds of document: a recurring restriction on spending, enacted as a rider to annual appropriations legislation, and a succession of internal guidance memoranda from the Department of Justice to federal prosecutors. Neither instrument rewrote the prohibition: the rider limited money available to enforce it in one setting, and the memoranda directed prosecutors toward some violations and away from others. Together, those two instruments determined, far more than the text of Schedule I did, whether a state licensed operator, a registered patient, or a caregiver faced federal investigation or charges during that period. The operative question after 2014 was therefore what Congress had forbidden the Department to spend money on during a particular fiscal year, and what the Department had told its prosecutors to prioritize during a particular administration.

The appropriations rider and the limits written into its text

The rider entered federal law as section 538 of the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235, signed on December 16, 2014. The provision became commonly known as the Rohrabacher-Farr amendment, after Representative Dana Rohrabacher of California and Representative Sam Farr of California, its principal House sponsors. Its operative language addressed spending rather than criminal liability: none of the funds made available in the act to the Department of Justice could be used, with respect to the listed states, to prevent those states from implementing their own state laws that authorized the use, distribution, possession, or cultivation of medical marijuana. The 2014 enactment listed more than thirty states together with the District of Columbia, and later renewals adjusted the list as additional states adopted medical programs. Congress did not repeal a prohibition, create a federal medical exception, direct the Drug Enforcement Administration to reschedule marijuana, or immunize any person from prosecution under federal law. Congress instead used its appropriations power to deny the executive branch funds for a category of enforcement activity during the period covered by that act, a familiar technique examined in the omnibus bills and riders article, where substantive policy often travels inside legislation whose formal purpose is funding the government for a defined period.

Three limits were built into the rider from its first enactment. The first limit was subject matter. The text referred to state laws authorizing medical marijuana, and it said nothing about state laws authorizing recreational or adult use marijuana. A state program licensing recreational cultivation and retail sale therefore stood outside the rider entirely, however carefully that program was regulated, and federal enforcement against recreational conduct depended on prosecutorial policy rather than on any congressional spending restriction. The second limit was institutional. The text restricted funds made available to the Department of Justice, the department that houses the Drug Enforcement Administration and the offices of the United States Attorneys. It did not rewrite the authorities of other federal agencies or disturb collateral federal regimes touching state authorized activity through taxation, banking, housing, employment, or firearms law. The third limit was temporal, and it proved the most consequential for planning. An appropriations rider enacted for one fiscal year expired with that fiscal year unless Congress enacted the restriction again in a later appropriations measure. The 2014 rider therefore had to be renewed, and Congress renewed the restriction in each following omnibus appropriations cycle, through short term extensions and successor acts, including the Consolidated Appropriations Act, 2018, Public Law 115-141, signed on March 23, 2018, which carried the medical marijuana restriction through the fiscal year ending September 30, 2018. Renewal was never automatic: each cycle required affirmative inclusion in negotiated appropriations text.

The distinction between a spending restriction and a change in substantive law mattered in practice. Because the rider amended no word of the Controlled Substances Act, conduct authorized by a state medical program remained a federal offense between 2014 and 2018, even in a listed state and even in complete conformity with state licensing rules. The rider also supplied no permanent defense. If Congress allowed the restriction to expire, the Department regained the ability to spend appropriated funds on the same conduct, and the Ninth Circuit in United States v. McIntosh expressly observed that prosecutions for conduct committed while the rider was in force could follow a later lapse, subject to the applicable statute of limitations. Operators, banks, and regulators all faced the same structural fact: the shield depended on an annual act of Congress, negotiated inside appropriations legislation that could stall for reasons unrelated to marijuana policy.

Is the appropriations rider a law that legalized medical marijuana?

No. The rider legalized nothing. It barred the Department of Justice from spending appropriated funds to prevent listed states from implementing state medical marijuana laws, and it left the Controlled Substances Act, including the Schedule I classification and every federal marijuana prohibition, entirely unchanged throughout the period it covered.

Judicial enforcement in the Ninth Circuit

The rider acquired practical force when defendants charged under the Controlled Substances Act asked federal courts to enforce it, and the leading appellate decision was United States v. McIntosh, 833 F.3d 1163, decided by the United States Court of Appeals for the Ninth Circuit in 2016. The case consolidated ten appeals from California and Washington involving defendants indicted for federal marijuana offenses who sought dismissal or injunctions on the ground that Congress had barred the Department from funding their prosecutions. The Department had argued that the rider prevented interference with states as governments but did not restrict prosecutions of private individuals. The Ninth Circuit rejected that narrower reading. Judge Diarmuid O’Scannlain reasoned for the panel that a state implements its medical marijuana laws through the individuals whom the state authorizes, so that prosecuting those individuals for state authorized conduct prevented the state from giving practical effect to its laws within the meaning of the rider. The court held that the appropriations restriction prohibited the Department from spending funds from the relevant appropriations acts on the prosecution of individuals who engaged in conduct permitted by state medical marijuana laws and who fully complied with those laws. The court also held that defendants had standing to raise the issue and were entitled to evidentiary hearings at which compliance with state law could be determined.

The same opinion also marked its boundaries precisely. The Ninth Circuit stated that individuals who did not strictly comply with all state law conditions regarding the use, distribution, possession, and cultivation of medical marijuana had engaged in conduct that was unauthorized, and that prosecuting such individuals did not violate the rider. Strict compliance became the operative standard in the Ninth Circuit, which covered California, Oregon, Washington, Arizona, Nevada, and other western states with large medical programs. A registration defect, a quantity in excess of a state limit, or a sale outside authorized channels could therefore move conduct outside the rider’s protection, and the burden at a hearing fell on proof of complete authorization rather than on good faith participation in a state program. The court further emphasized the temporal character of the protection, warning that the ruling applied while the rider remained in force, that Congress could appropriate funds for such prosecutions in a later act, and that the absence of funding in one period supplied no guarantee about appropriations in the next. Judicial enforcement thus converted an appropriations clause into an individually invocable limit on prosecution, but the conversion preserved every fragility of the source material: annual duration, medical only coverage, listed state coverage, and a strict compliance threshold that left partially compliant conduct exposed to the unchanged federal prohibition.

Guidance memoranda and the exercise of prosecutorial discretion

The second layer predated the rider and rested entirely inside the executive branch. Federal prosecutors possess broad discretion over charging decisions, and the Department coordinates that discretion through written guidance. On October 19, 2009, Deputy Attorney General David W. Ogden issued a memorandum to selected United States Attorneys concerning investigations and prosecutions in states authorizing the medical use of marijuana. The Ogden memorandum stated that the Department did not consider it an efficient use of limited federal resources to focus on individuals whose actions were in clear and unambiguous compliance with existing state laws providing for the medical use of marijuana, a formulation covering patients and their caregivers. It directed prosecutors toward significant traffickers and conduct violating state law, and it cautioned that commercial enterprises that unlawfully marketed marijuana for profit remained targets. The document changed no element of any offense: it announced an allocation of resources, and its protection depended on the clarity of a defendant’s compliance and on each administration’s willingness to honor the allocation.

After Colorado and Washington voters approved recreational legalization in November 2012, a second memorandum broadened that guidance. On August 29, 2013, Deputy Attorney General James M. Cole issued a memorandum to all United States Attorneys providing guidance regarding marijuana enforcement. The Cole memorandum restated that marijuana remained an illegal substance under the Controlled Substances Act, and it then identified eight enforcement priorities that would guide federal enforcement of the marijuana prohibition. Those priorities, expressed in a single governing framework, were preventing the distribution of marijuana to minors, preventing revenue from the sale of marijuana from going to criminal enterprises, gangs, and cartels, preventing the diversion of marijuana from states where the drug was legal under state law to other states, preventing state authorized marijuana activity from being used as a cover or pretext for the trafficking of other illegal drugs or other illegal activity, preventing violence and the use of firearms in the cultivation and distribution of marijuana, preventing drugged driving and the exacerbation of other adverse public health consequences associated with marijuana use, preventing the growing of marijuana on public lands and the attendant public safety and environmental dangers posed by production on public lands, and preventing marijuana possession or use on federal property. Outside those priorities, the memorandum stated, the federal government had traditionally relied on state and local enforcement, particularly where a state had established a strong and effective regulatory system. Robust state regulation could affirmatively address the federal priorities, and the size or commercial nature of an operation, standing alone, was not a reason for federal intervention.

The Cole memorandum became the central planning document for state regimes between 2013 and 2018 because it supplied criteria that state legislation could be drafted to satisfy, and states building recreational programs after 2013 defended their licensing, tracking, and testing systems by reference to its priorities. Its legal status, however, was narrower than its practical influence suggested. The memorandum stated that it was intended solely as guidance for the exercise of investigative and prosecutorial discretion, that it created no rights enforceable by any party, and that it did not alter the Department’s authority to enforce federal law regardless of state law. A prosecutor could depart from the guidance without violating a statute or court order, and a defendant charged despite full compliance with state law could not obtain dismissal merely by pointing to the memorandum. The protection was real in the sense that federal resources were directed elsewhere in states with functioning regulatory systems between 2013 and 2017, and contingent because the direction existed only at the pleasure of the issuing officials and their successors.

Rescission and the return to district level discretion

That contingency ceased to be theoretical on January 4, 2018, when Attorney General Jeff Sessions issued a one page memorandum to all United States Attorneys rescinding the Cole memorandum, the Ogden memorandum, and other nationwide guidance specific to marijuana enforcement, effective immediately. The Sessions memorandum stated that previous nationwide guidance specific to marijuana enforcement was unnecessary in light of the general principles in the United States Attorneys’ Manual, and it directed prosecutors to weigh considerations applicable to federal prosecutions generally, including the seriousness of the crime, the deterrent effect of prosecution, and the cumulative impact of particular crimes on the community. The memorandum ordered no specific prosecutions. Its legal effect was subtractive: it removed the framework that had told prosecutors to treat the eight Cole priorities as the focus of marijuana enforcement and to leave well regulated state systems principally to state enforcement. After January 4, 2018, the governing federal text for recreational marijuana consisted of the Controlled Substances Act and the general principles of federal prosecution, while medical marijuana retained the rider’s protection for conduct in strict compliance with state law in listed states.

Enforcement posture after the rescission therefore rested with individual United States Attorneys, and public statements from those officials in legalization states varied in the weeks following January 4, 2018. The United States Attorney for the District of Colorado, Bob Troyer, stated that the rescission would not change the approach of that office, which focused on persons creating the greatest safety threats to Colorado communities. Other United States Attorneys emphasized case by case evaluation under general principles or the continuation of existing priorities without adopting the Cole framework as such. The variation was a predictable product of the instrument Sessions had chosen: a memorandum restoring general discretion necessarily produced district level readings, filtered through local conditions and each chief prosecutor’s judgment. A recreational operator in Colorado, a medical provider in California protected by the rider, and a recreational operator in a state whose United States Attorney announced a more aggressive posture faced materially different federal environments after January 2018, even though the federal statute governing all three had not changed by a single word.

The episode also clarified the hierarchy among the instruments that composed the practical regime. The appropriations rider, although temporary, was legislation: it bound the Department because the Constitution permits executive spending only pursuant to appropriations made by law, and a federal court in McIntosh enforced it at the request of individual defendants. The memoranda, although influential, were internal policy statements: each bound prosecutors only as a matter of departmental management, none bound a court, none created an enforceable right, and each remained revocable by the Attorney General or a successor without congressional action and without judicial approval. Sessions exercised exactly that revocability on January 4, 2018, for guidance issued in 2009 and 2013. The rider occupied a middle position in durability: extension required agreement between the House and the Senate and a presidential signature, yet no single executive official could withdraw the protection by memorandum while an enacted rider remained in force.

The resulting structure, on September 1, 2018, combined permanence in prohibition with impermanence in enforcement. The statute never changed: marijuana remained in Schedule I, federal offenses and penalties remained in Title 21 of the United States Code, and state authorization supplied no federal statutory defense. The spending restriction changed with each fiscal year: enacted in December 2014, renewed through successive omnibus acts, carried into the act signed on March 23, 2018, and scheduled to expire on September 30, 2018, unless Congress enacted it again. The discretion layer changed with administrations: deprioritization guidance in October 2009, a priority framework in August 2013 that accommodated both medical and recreational state systems with strong regulation, and a rescission in January 2018 that returned marijuana to the general principles applicable to all federal offenses. Millions of patients, caregivers, licensees, employees, and investors lived and transacted inside the space created by the distance between the permanent prohibition and its temporary, revocable nonenforcement. That distance was the regime itself, assembled from the two least durable instruments in the federal toolkit, an appropriations rider that expired with the fiscal year and prosecutorial guidance that expired with the tenure of the officials who signed it, and the remainder of the comparison between federal drug law and state legalization turns on that fact.

The Coexistence Table

The table records the comparison in compressed form, area by area, against the law in force on September 1, 2018.

Area of activity	What federal law says	What state law may say	Does preemption apply	What actually governs in practice
Personal possession by an adult	Federal offense under section 844	Permitted within state limits	No	State law, absent a federal charge
Home cultivation	Federal offense under section 841	Permitted within state plant limits	No	State law, with federal exposure retained
Licensed retail sale	Federal offense under section 841	Licensed and taxed by the state	No	State licensing, with federal exposure retained
Registered medical use	Schedule I, no federal medical exception	Authorized for registered patients	No	State program, shielded in part by the rider
Banking services for a licensed business	Proceeds of a federal offense; Bank Secrecy Act duties apply	Accounts permitted under state law	No	Bank compliance decisions under federal law
Federal income tax deductions for a licensed business	Section 280E denies ordinary deductions	Deductions governed by state tax law	No	Section 280E on the federal return
Firearm purchase by a user	Barred by 18 U.S.C. 922(g)(3)	State law holds no federal exception	No	The federal firearms prohibition
Immigration consequences of use	Inadmissibility and deportability grounds apply	State legality holds no federal effect	No	Federal immigration law
Federal employment	Illegal drug use bars suitability under Executive Order 12564	State legality holds no federal effect	No	Federal workplace and testing rules
Research supply	DEA registration and a federally authorized source required	A state license alone is insufficient	No	Federal registration and supply controls

The criminal comparison alone leaves two federal systems untouched, because banking and taxation applied the Schedule I classification to a licensed business without any prosecution at all.

Collateral consequences I: banking and the tax code

A state license settles only what state law permits. A business licensed by a state to cultivate or sell marijuana operates under a state system of applications, inspections, tracking, and state taxes, and at the same time inside a federal system that classifies marijuana as a Schedule I controlled substance under the Controlled Substances Act. The conflict also operates through two channels that require no prosecutor at all. The first is the banking system, where federal anti money laundering law governs access to deposit accounts and payment services. The second is the federal income tax, where a single provision of the Internal Revenue Code denies the ordinary deductions that determine whether a retailer is taxed on profit or on something close to gross receipts. Both channels attach automatically to the federal classification.

Why will banks not open accounts for state-licensed marijuana businesses?

Federal law treats marijuana proceeds as proceeds of a federal offense, and the Bank Secrecy Act requires banks to monitor customers and file suspicious activity reports. A bank that accepts such deposits faces possible money laundering exposure under federal law, examination criticism, and loss of access to federal payment services.

The reluctance of banks rested on statute rather than on institutional preference. The Controlled Substances Act prohibits the manufacture, distribution, and dispensing of marijuana, and federal law treats revenue derived from a violation of that prohibition as proceeds of unlawful activity. Section 1956 of Title 18 prohibits financial transactions conducted with the proceeds of specified unlawful activity, including Controlled Substances Act offenses, when the transaction is designed to promote the activity, conceal the source of the proceeds, or evade a reporting requirement. Section 1957 of Title 18 separately prohibits monetary transactions in criminally derived property above a threshold amount, reaching ordinary deposits and expenditures through a financial institution. A dispensary that deposits daily receipts, pays a landlord by check, or runs payroll from an account therefore presents a bank with a customer whose core revenue stream falls within the federal definition of criminally derived property, regardless of the state license displayed on the dispensary wall.

The Bank Secrecy Act adds a second layer of obligation. The Act and its regulations require financial institutions to maintain anti money laundering programs, to conduct customer due diligence, to monitor transactions, and to file suspicious activity reports and currency transaction reports with the Financial Crimes Enforcement Network, a bureau of the Department of the Treasury. For an ordinary retail customer, the bank can establish the expected pattern of activity and treat departures from that pattern as the signal that warrants a report. For a marijuana related business, the baseline activity itself consists of transactions in the proceeds of a federal offense, so the bank must document the state license, verify compliance with state regulations, monitor the business against federal enforcement priorities, and file reports on a continuing basis. Examination adds a further risk, because an examiner may treat the relationship as an unsafe or unsound practice or direct the bank to exit the relationship.

The predictable response between state legalization and February 2014 was refusal. Most large national banks declined marijuana related accounts as a matter of policy, and many community banks and credit unions reached the same result after weighing compliance cost against deposit value. Businesses that could not obtain or retain accounts operated in cash. Cash operation complicated wage withholding, employment tax deposits, and recordkeeping, and payment of taxes in cash required in person delivery to tax agency offices under Internal Revenue Service procedures for cash intensive businesses without bank accounts. Large volumes of cash on premises increased robbery risk and required expenditure on safes, armored transport, surveillance, and private security. Cash operation also deprived the business of card payment processing, lines of credit, and commercial lending.

The FinCEN guidance and the limits of accommodation

The federal government addressed the banking impasse through guidance rather than through legislation or rulemaking. On February 14, 2014, the Financial Crimes Enforcement Network issued guidance designated FIN-2014-G001, titled BSA Expectations Regarding Marijuana-Related Businesses. The guidance stated that it clarified how financial institutions could provide services to marijuana related businesses consistent with obligations under the Bank Secrecy Act. The document did not amend the Controlled Substances Act, the money laundering statutes, or any Bank Secrecy Act regulation, and the document did not purport to legalize any transaction. Instead, the guidance organized compliance around the enforcement priorities in the memorandum issued on August 29, 2013 by Deputy Attorney General James M. Cole, which directed federal prosecutors to focus marijuana enforcement on eight priorities, including distribution to minors, revenue flowing to criminal enterprises, diversion to a state where distribution was prohibited, and use of state authorized activity as a cover for trafficking in other substances.

Under the FinCEN guidance, a financial institution was expected to conduct customer due diligence that included verifying licensure with state authorities, reviewing the license application, understanding the normal and expected activity of the business, monitoring for suspicious activity on an ongoing basis, and periodically refreshing customer information. The reporting framework created three categories of suspicious activity report keyed to the Cole priorities. A report designated marijuana limited was filed when the institution, after due diligence, reasonably believed that the business did not implicate a Cole priority and did not violate state law; the report was filed solely because the customer engaged in a marijuana related business. A report designated marijuana priority was filed when the institution believed that the business did implicate a Cole priority or did violate state law. A report designated marijuana termination was filed when the institution terminated a relationship to maintain an effective anti money laundering program. The guidance also denied an exemption from currency transaction reporting.

The accommodation was partial in two respects. First, the guidance reduced uncertainty about the form of compliance without reducing the underlying legal exposure, because the guidance created a reporting pathway for conduct that federal criminal law continued to prohibit. Second, the framework depended on a prosecutorial memorandum that the Attorney General could withdraw without rulemaking or congressional action. That dependence became concrete on January 4, 2018, when Attorney General Jeff Sessions rescinded the Cole memorandum and related guidance. The rescission removed the enforcement framework to which the FinCEN guidance was keyed, leaving institutions to determine whether a Treasury document built around rescinded Justice Department priorities retained practical force.

The Treasury Department answered that question in stages during January and February 2018, preserving the guidance without restoring the Cole memorandum. Sigal Mandelker, Deputy Secretary of the Treasury, testified before a Senate committee in January 2018 that the Department was reviewing the FinCEN guidance in light of the Attorney General decision and that the guidance remained in place during the review. In a letter dated February 1, 2018, the Treasury Department informed members of Congress that the Department was reviewing the guidance in consultation with law enforcement and that the guidance remained in effect in the meantime. Secretary Steven Mnuchin, testifying before the House Financial Services Committee on February 6, 2018, confirmed the review and stated that the intent was not to withdraw the guidance without a replacement. By September 1, 2018, the guidance of February 14, 2014 had not been withdrawn or replaced. An enforcement memorandum can organize discretion, and a guidance document can organize reporting, but neither instrument changes the statutory classification that generates the banking problem.

Account access in the courts and the Fourth Corner litigation

The account access question reached the federal courts through an institution created to serve the industry. The Fourth Corner Credit Union obtained a Colorado state charter in November 2014 to provide financial services to marijuana related businesses, and the credit union applied to the Federal Reserve Bank of Kansas City for a master account. A master account gives a depository institution access to Federal Reserve services, including the electronic payment system through which transactions settle. The Reserve Bank denied the application in 2015, and Fourth Corner filed suit in the United States District Court for the District of Colorado seeking a declaratory judgment and an injunction requiring issuance of the account. The district court dismissed the complaint in January 2016. District Judge R. Brooke Jackson reasoned that a court could not order a Federal Reserve Bank to grant access that would facilitate activity prohibited by federal law, treating the Cole memorandum and the FinCEN guidance as documents suggesting that prosecutors might decline enforcement rather than documents that changed the governing law.

The United States Court of Appeals for the Tenth Circuit decided the appeal on June 27, 2017 in Fourth Corner Credit Union v. Federal Reserve Bank of Kansas City, 861 F.3d 1052 (10th Cir. 2017), and the decision produced no majority rationale. Each member of the three judge panel wrote separately. Judge Moritz would have affirmed dismissal with prejudice, because relief would facilitate conduct prohibited by the Controlled Substances Act and because neither the Cole memorandum nor the FinCEN guidance nullified that Act or the money laundering statutes. Judge Matheson concluded that the dispute was not ripe, because the amended complaint alleged that service would occur only if authorized by law, and the Reserve Bank might grant an application framed on that basis. Judge Bacharach would have reversed outright, reasoning that the amended allegation deserved a presumption of truth and that 12 U.S.C. 248a(c)(2) entitled nonmember depository institutions to Federal Reserve services on the same schedule as member banks. Because two opinions supported a disposition short of affirmance with prejudice, the court vacated the judgment and remanded with instructions to dismiss the amended complaint without prejudice, leaving Fourth Corner free to replead. No order required issuance of a master account.

Section 280E and taxation on a near gross basis

The tax consequence operates through a provision enacted decades before any state authorized a licensed marijuana market. Section 280E of Title 26 denies any deduction or credit for amounts paid or incurred in carrying on a trade or business that consists of trafficking in controlled substances within the meaning of Schedule I and Schedule II of the Controlled Substances Act, where the trafficking is prohibited by federal law or by state law. Congress enacted the provision in the Tax Equity and Fiscal Responsibility Act of 1982, Public Law 97-248, one year after the Tax Court decided Edmondson v. Commissioner, T.C. Memo. 1981-623. In Edmondson, the Tax Court held that a taxpayer selling amphetamines, cocaine, and marijuana could recover cost of goods sold and deduct ordinary and necessary expenses, including portions of rent, telephone expense, and automobile expense. The Senate Finance Committee report accompanying the 1982 legislation stated a sharply defined public policy against drug dealing. The statute reversed the Edmondson result for deductions while preserving cost of goods sold, which the committee report left unaffected to preclude possible challenges on constitutional grounds.

The distinction between cost of goods sold and a deduction determines the economic effect of Section 280E. Cost of goods sold is an exclusion from gross receipts in computing gross income rather than a deduction from gross income. Section 280E does not deny the cost of goods sold adjustment, so a marijuana business subtracts the cost of inventory sold and then loses the deductions that an ordinary retailer would claim for rent, wages, utilities, insurance, marketing, professional fees, and security, to the extent that those amounts are expenses of the trafficking business rather than inventory costs. The result is taxation on a base close to gross profit, which can exceed economic net income by a wide margin. Effective federal rates for dispensaries under Section 280E therefore ran far above the rates borne by comparable retailers. Courts sustained application of the statute to state licensed dispensaries because trafficking prohibited by federal law satisfies the statute even when the same conduct complies with state law.

Separate businesses in CHAMP and Olive

Litigation under Section 280E concentrated on one question: whether a taxpayer that sells marijuana also carries on a second, separate trade or business whose expenses fall outside the disallowance. The Tax Court answered affirmatively on the facts of Californians Helping to Alleviate Medical Problems, Inc. v. Commissioner, 128 T.C. 173 (2007). The taxpayer, known by the acronym CHAMP, operated a San Francisco community center that provided counseling, support groups, educational classes, meals, and other caregiving services to members with debilitating illnesses, and the taxpayer also provided medical marijuana to members under the California Compassionate Use Act of 1996 in exchange for a single membership fee. The Commissioner disallowed every deduction as an expense of trafficking. The Tax Court held that caregiving and the provision of medical marijuana were separate trades or businesses for purposes of Section 280E, based on the extent of the caregiving activity, the health services experience of the executive director, the proportion of employees assigned to caregiving, and the substantial difference between the services and the distribution of marijuana. Section 280E barred expenses attributable to the marijuana activity, and the statute did not bar expenses properly allocated to the caregiving business.

The United States Court of Appeals for the Ninth Circuit refused the same separation on different facts in Olive v. Commissioner, 792 F.3d 1146 (9th Cir. 2015), affirming the Tax Court decision reported at 139 T.C. 19 (2012). Martin Olive operated the Vapor Room, a San Francisco medical marijuana dispensary and consumption lounge that provided patrons with counseling, movies, yoga, massage, and beverages without separate charge. The Tax Court found a single trade or business, the sale of marijuana, because the complementary services were offered free of charge, generated no independent revenue, and served to promote sales and attract patrons. The Ninth Circuit affirmed the disallowance and agreed that an enterprise whose sole product is marijuana and whose additional services exist only as incidents of the sale has one trade or business within the meaning of the statute. The line is the factual independence of the second activity.

Banking exclusion and deduction disallowance share a feature that distinguishes both from the criminal prohibitions of the Controlled Substances Act. Neither consequence requires a prosecutor, a charge, an indictment, or a conviction. A bank applies the Bank Secrecy Act and the money laundering statutes when an account is opened and when an examiner reviews the relationship, and the Internal Revenue Service applies Section 280E when a return is filed and examined. Both consequences flow automatically from continued placement of marijuana in Schedule I, because the money laundering definition incorporates Controlled Substances Act offenses and Section 280E incorporates the schedules of that Act by reference. A state legislature can repeal state penalties, create a licensing system, and impose state taxes, and none of those actions amends the federal schedules, the federal money laundering definitions, or the federal deduction disallowance. The consequences therefore persisted in every legalization state during that period, regardless of state law and regardless of whether any prosecution was filed where the business operated.

Banking and taxation reached the licensed business, and a second set of federal regimes reached the individual through immigration, firearms, employment, housing, and research rules.

Collateral Consequences II: Immigration, Firearms, Employment, Housing, and Research

Prosecution was only one channel through which federal drug law reached conduct that a state had chosen to permit. By September 2018, the federal definition of a controlled substance also operated inside immigration adjudication, firearms transfers, federal employment and contracting, public housing admissions and leases, and research licensing. Each field had a distinct statute, decision maker, and remedy, yet each borrowed the classification of marijuana as a Schedule I controlled substance under the Controlled Substances Act. A state license or registry card therefore changed state exposure without changing the federal premise, and consequences attached often without any federal criminal charge.

Immigration Status and Naturalization

The Immigration and Nationality Act tied admissibility and deportability directly to controlled substance violations defined by federal law. Under 8 U.S.C. 1182(a)(2)(A)(i)(II), a noncitizen who had been convicted of, who admitted having committed, or who admitted committing acts that constituted the essential elements of a violation of a law relating to a controlled substance, as defined in 21 U.S.C. 802, was inadmissible. The admission branch mattered because it required no conviction. A formal admission of the essential elements during a visa or adjustment process could supply the ground on its own terms, even where the conduct had produced no prosecution.

Deportability followed a parallel but narrower structure. Under 8 U.S.C. 1227(a)(2)(B)(i), a noncitizen who at any time after admission had been convicted of a violation of a state, federal, or foreign law or regulation relating to a controlled substance was deportable. The same paragraph contained a precisely drawn textual exception for a single offense involving possession for personal use of 30 grams or less of marijuana. Section 1227(a)(2)(B)(ii) separately made a noncitizen who was, or at any time after admission had been, a drug abuser or addict deportable.

A second inadmissibility ground reached conduct without either a conviction or an admission. Under 8 U.S.C. 1182(a)(2)(C), a noncitizen whom a consular officer or the Attorney General knew or had reason to believe was or had been an illicit trafficker in a controlled substance, or a knowing aider, abettor, assister, conspirator, or colluder in illicit trafficking, was inadmissible. Because federal law treated the manufacture, distribution, and dispensing of marijuana outside federally authorized channels as trafficking conduct, employment inside a state licensed marijuana business sat uneasily within the federal framework. Duties involving cultivation, processing, transport, or sale corresponded, in federal vocabulary, to manufacture and distribution, regardless of the state license attached to the enterprise.

Relief from the 30 gram threshold illustrated the calibration with particular clarity. The deportability paragraph in 1227(a)(2)(B)(i) excluded the qualifying single possession offense by its own text. Inadmissibility under 1182(a)(2)(A)(i)(II) contained no corresponding automatic exclusion. Relief instead ran through the discretionary waiver in 8 U.S.C. 1182(h), which permitted a waiver, in specified circumstances, where the inadmissibility related to a single offense of simple possession of 30 grams or less of marijuana. Quantity, simplicity of possession, and singleness of the offense therefore each carried legal weight.

Naturalization added a further layer through the good moral character requirement. Under 8 U.S.C. 1101(f)(3), a person described in specified controlled substance provisions of 1182(a)(2) could not be found to have good moral character during the statutory period, subject to the same single offense simple possession exception for 30 grams or less of marijuana. Marijuana related conduct thus bore on naturalization even where removal was never pursued, because an admission in an examination could connect the application to the inadmissibility grounds described in this section.

Can a State-Legal Marijuana User Legally Own a Firearm?

No. Under the federal statute in force in September 2018, a person who used marijuana, even under a state medical or recreational program, was an unlawful user of a controlled substance and could not lawfully possess, receive, ship, or transport firearms or ammunition in or affecting interstate commerce.

The governing text was 18 U.S.C. 922(g)(3). That paragraph made it unlawful for a person who was an unlawful user of or addicted to any controlled substance, as defined in section 102 of the Controlled Substances Act and codified at 21 U.S.C. 802, to ship or transport a firearm or ammunition in interstate or foreign commerce, to possess a firearm or ammunition in or affecting commerce, or to receive a firearm or ammunition shipped or transported in such commerce. A companion provision, 18 U.S.C. 922(d)(3), barred transfers to persons within the same category where the transferor had the specified knowledge. Federal law recognized no general category of lawful marijuana use created by state legislation. Outside narrow federally authorized channels, principally research conducted under federal registration, marijuana use was a federal offense, and a state medical recommendation or recreational authorization did not convert the user into a lawful user under 922(g)(3). The Bureau of Alcohol, Tobacco, Firearms and Explosives stated that position expressly in an open letter to all federal firearms licensees dated September 21, 2011. In paraphrase, the letter treated any person who used marijuana, regardless of state authorization for medical purposes, as an unlawful user prohibited from possessing firearms or ammunition, and it treated possession of a state card authorizing marijuana use as reasonable cause for a licensee to believe that a prospective transferee fell within the prohibition. The broader setting appears in the federal versus state firearms law article, which traces the division between federal and state firearms regulation.

The transfer form translated the statute into a question at the counter. ATF Form 4473, revised in October 2016 and required for use beginning January 16, 2017, asked in question 11.e whether the transferee was an unlawful user of, or addicted to, marijuana or another controlled substance, and the revised form added a bold warning, paraphrased here, that the use or possession of marijuana was unlawful under federal law regardless of legalization or decriminalization for medical or recreational purposes in the state of residence. The revision changed no statute, but after 2016 the federal position appeared on the form itself.

Litigation tested the dealer side of the rule. In Wilson v. Lynch, 835 F.3d 1083 (9th Cir. 2016), Rowan Wilson, a Nevada medical marijuana registry cardholder, challenged 18 U.S.C. 922(g)(3) and 922(d)(3), together with the 2011 open letter, after a dealer refused a sale upon learning of the registry card. The United States Court of Appeals for the Ninth Circuit rejected the Second Amendment challenge to the transfer prohibition as applied to registry cardholders, holding that the prohibition survived intermediate scrutiny because it furthered the governmental interest in preventing gun violence, and the court rejected a due process theory premised on a protected liberty interest in simultaneously holding a registry card and purchasing a firearm.

Federal Employment, Contracting, and Security Clearances

Federal employment law approached marijuana through suitability and workplace rules rather than through the criminal code alone. President Ronald Reagan signed Executive Order 12564, titled Drug-Free Federal Workplace, on September 15, 1986. The order required federal employees to refrain from the use of illegal drugs, declared such use, whether on duty or off duty, contrary to the efficiency of the service, and stated that persons who used illegal drugs were not suitable for federal employment. Agency plans covered testing in sensitive positions and procedures for referral, discipline, and rehabilitation. Because the order rested on illegal drug use under federal law, a state decision to permit marijuana use did not remove marijuana from the substances covered by the federal employment policy.

Congress extended a related model through the Drug-Free Workplace Act of 1988, codified in provisions later recodified at 41 U.S.C. 8101 and following sections. The Act conditioned specified federal contracts and federal grants on an employer agreement to maintain a drug free workplace. Covered organizations were required to publish a statement prohibiting the unlawful manufacture, distribution, dispensation, possession, or use of a controlled substance in the workplace, to establish a drug free awareness program, to notify the contracting or granting agency of specified employee drug convictions in the workplace, and to impose sanctions or require participation in an assistance or rehabilitation program. Federal remedies for noncompliance included suspension of payments, termination of the contract or grant, and suspension or debarment from further awards for a period of up to five years. The Act imposed program obligations on employers and did not, by its own terms, impose a general drug testing mandate on every covered contractor or grantee.

Transportation supplied the most developed testing regime. The Omnibus Transportation Employee Testing Act of 1991 directed the Department of Transportation to expand alcohol and drug testing for safety sensitive transportation employees, and departmental rules covered aviation, trucking, railroads, mass transit, and pipelines. Departmental regulations treated a verified positive test for marijuana as a violation requiring removal from a safety sensitive function, followed by an evaluation and return to duty process administered through a substance abuse professional. In testimony and guidance issued between 2012 and 2014, the Department of Transportation stated that state medical and recreational marijuana laws did not change the federal testing rules for covered employees, because marijuana was a Schedule I substance in the federal testing panel.

Security clearance adjudication applied a similar federal premise in a different setting. Federal adjudicative guidelines treated illegal drug involvement, including the use, possession, manufacture, and distribution of a controlled substance in violation of federal law, as conduct that raised questions about reliability, judgment, and willingness to comply with laws and regulations. Adjudicators evaluated recency, frequency, circumstances, and evidence of rehabilitation under the whole person concept. State authorization did not reclassify the conduct as lawful for clearance purposes, and employment in a state licensed marijuana enterprise could itself present questions about an activity that federal law defined as criminal manufacture or distribution.

Public and Assisted Housing

Public housing law converted the federal definition into admission and lease rules that affected an entire household. The Quality Housing and Work Responsibility Act of 1998 amended the United States Housing Act in provisions codified at 42 U.S.C. 13661 and 13662. Section 13662 required owners of federally assisted housing to prohibit admission to an applicant household in which a member was illegally using a controlled substance, and the statutory scheme required public housing agencies and owners to use lease provisions under which drug related criminal activity on or off the premises, by a tenant, a household member, a guest, or another person under the control of the tenant, furnished cause for termination of tenancy. Because the governing definitions looked to illegal use and criminal activity measured against federal controlled substance law, marijuana use authorized by a state medical or recreational statute counted as illegal use inside the federal housing programs.

The Department of Housing and Urban Development addressed the conflict directly in 2011. An Office of General Counsel memorandum dated January 20, 2011, signed by General Counsel Helen R. Kanovsky, reaffirmed a 1999 departmental memorandum and concluded that a state law purporting to legalize medical marijuana use in public or assisted housing conflicted with the admission and termination standards of the Quality Housing and Work Responsibility Act. The memorandum rejected the proposition that federal or state nondiscrimination law required a reasonable accommodation permitting medical marijuana use in federally assisted housing, on the ground that the use was illegal under the Controlled Substances Act. Departmental guidance issued during 2011 for public housing agencies and owners of assisted housing left the mandatory admission denial in place for an applicant determined to be using marijuana, while program materials distinguished admission, where denial was required, from termination of an existing tenancy, where the housing authority or owner exercised discretion under the lease and program rules within the termination authority that the statute required the lease to contain.

The household structure of the housing rules gave the federal definition a reach distinct from an individual criminal penalty. Admission screening examined the household rather than only the named applicant, and lease termination provisions extended to conduct by guests and other persons under the control of the tenant. A single member whose marijuana use was lawful under state law could therefore determine the admission outcome for the household, and drug related activity attributed to a guest could place the tenancy itself at issue, subject to the discretion and procedural protections that program regulations and the lease supplied in a termination case.

Research Registration and Supply

Research presented the conflict in an inverted form. Schedule I placement rested, under 21 U.S.C. 812(b)(1), on findings of a high potential for abuse, no accepted medical use in treatment in the United States, and a lack of accepted safety for use under medical supervision, and the same placement imposed the heaviest research controls in the Controlled Substances Act. A scientist who proposed to study marijuana required a separate researcher registration from the Drug Enforcement Administration under 21 U.S.C. 823(f), apart from any state license, institutional approval, or, for a clinical investigation, authorization through the Food and Drug Administration investigational new drug process. Under 823(f), the Attorney General, acting through the Drug Enforcement Administration, referred the application and the research protocol to the Secretary of Health and Human Services, who determined the qualifications and competency of the applicant and the merits of the protocol. Regulations at 21 C.F.R. 1301.32 structured that referral and review, so protocol design itself became a federal licensing question before any substance changed hands.

Supply formed a second gate. For decades before August 2016, marijuana for federally authorized research in the United States came through a single channel: a grower at the University of Mississippi operating under contract with the National Institute on Drug Abuse, which administered distribution to registered researchers through its drug supply program. A researcher therefore needed both a registration covering the protocol and access to material produced inside the single federally contracted source, rather than material drawn from the state licensed market where the laboratory sat.

On August 11, 2016, the Drug Enforcement Administration announced a policy intended to widen that channel, and the policy statement appeared in the Federal Register on August 12, 2016, at 81 Fed. Reg. 53846, under the title Applications To Become Registered Under the Controlled Substances Act To Manufacture Marijuana To Supply Researchers in the United States. The announcement stated that the agency would accept applications for additional bulk manufacturer registrations under 21 U.S.C. 823(a), ending the single grower arrangement as a matter of stated policy. On the same day, the agency denied petitions to move marijuana out of Schedule I, so the registration and protocol controls attached to Schedule I formed the framework inside which any additional manufacturer would operate.

Implementation lagged behind the announcement through the period ending in August 2018. A June 6, 2018 opinion of the Department of Justice Office of Legal Counsel, addressing the licensing of marijuana cultivation for research, recorded that several entities had applied under the 2016 policy and that no application had been approved. No additional bulk manufacturer license had issued by September 1, 2018, and the University of Mississippi contract was the sole federally authorized source of research marijuana for the period covered by this article.

Those consequences attached to individuals and institutions under federal definitions, and the state regimes that triggered the consequences had taken a distinctive shape on the ground between 1996 and 2018.

The State Regimes in Practice, the Contested Arguments, and the Verdict

The comparison between federal drug law and state legalization turns less on declarations than on machinery. A federal prohibition in the Controlled Substances Act and a state decision to withdraw a state prohibition can occupy the same territory because each sovereign controls a separate code, separate penalties, and, in ordinary practice, separate enforcement personnel. The state regimes built between 1996 and 2018 began as narrow shields for patients, developed into systems that licensed and tracked a commercial supply chain, and spread through ballot measures that ended, in January 2018, with a legislature acting without an initiative. At every stage, a state instrument changed state law alone, the federal prohibition remained intact, and conduct that a state license documented remained conduct that federal law forbade. That paradox defined the arrangement and determined where a resolution had to come from.

What Legalization Statutes Build on the Ground

California voters approved Proposition 215, the Compassionate Use Act, in November 1996, and the measure supplied the template for the first generation of state medical laws. Proposition 215 provided that California provisions punishing possession and cultivation did not apply to a patient, or to a primary caregiver, who possessed or cultivated marijuana for the personal medical purposes of the patient upon the recommendation or approval of a physician. California courts, including the California Supreme Court in People v. Mower in 2002, read the measure as providing an affirmative defense rather than immunity from arrest. A patient could raise medical use as a defense to a state prosecution, but the measure created no licensed supply system and no retail market. The California Legislature added Senate Bill 420 in 2003 to clarify identification and cooperative cultivation. The first legal act in early adopting states was subtraction, through removal or narrowing of state penalties, or creation of a defense, for a defined class of patients and caregivers. Licensing followed later.

Later medical regimes, and the recreational regimes that followed, built administrative structures on top of that subtraction. A mature program by 2018 characteristically created separate licenses for cultivators, processors, testing laboratories, transporters in some states, and retailers or dispensaries, with fees, background checks, security and record keeping obligations, and grounds for suspension or revocation. Testing laboratories occupied a distinctive place, because a state that authorized sale of a plant product for consumption assumed responsibility for potency labeling and for screening against pesticides, mold, and other contaminants. Seed to sale tracking required licensees to record a plant or a batch through cultivation, harvest, processing, testing, transport, and retail sale, so that a regulator could trace a product backward and detect diversion into unlicensed channels. Possession and purchase limits set the lawful quantity for a patient or an adult consumer, home cultivation rules set plant counts in states that permitted cultivation at home, and recreational regimes confined purchase and possession to adults aged twenty one or older.

Two further features kept the systems local in structure. Many regimes allowed a city or a county to prohibit licensed businesses within its borders, to limit the number or location of such businesses, or to impose local taxes and zoning conditions beyond the state floor, so that a state license remained necessary but not sufficient to open in a particular place. States also imposed tax structures in varying combinations: excise taxes at cultivation, wholesale, or retail stages, general sales taxes, and local taxes, with portions of revenue in several states dedicated to education, public health, treatment, or enforcement. Each state designed a self contained market, because interstate transport remained a federal offense and because a product lawful in one state held no lawful status in a state that prohibited the product.

The recreational sequence proceeded by ballot initiative for the first eight states. Colorado and Washington voters legalized recreational use in November 2012, Oregon and Alaska voters followed in November 2014, and California, Massachusetts, Nevada, and Maine voters followed in November 2016. The District of Columbia adopted Initiative 71 in 2014, legalizing possession and home cultivation for adults, while Congress used appropriations authority over the District to block a regulated retail sales system there. Vermont broke the initiative pattern in January 2018. Governor Phil Scott signed House Bill 511 on January 22, 2018, after passage by the Vermont Legislature, and the law took effect on July 1, 2018, legalizing possession of up to one ounce and cultivation of a limited number of plants for adults aged twenty one or older. Vermont ranked as the ninth state to legalize recreational use and as the first state to do so through legislation rather than through a ballot initiative, a distinction explained in part by the absence of a citizen initiative mechanism in Vermont law. The Vermont enactment established no licensed commercial retail system.

By September 2018, nine states and the District of Columbia permitted recreational use, and the National Conference of State Legislatures counted thirty one states, together with the District of Columbia, Guam, and Puerto Rico, with comprehensive public medical marijuana programs after Oklahoma voters approved State Question 788 on June 26, 2018. None of the state instruments purported to amend federal law, and none had legal capacity to do so. Each amended a state constitution, a state statute, or state regulations, and each derived force from the power of a state to define offenses under state law and to direct state and local officers. A state license therefore performed a double function. The license proved compliance with state conditions on testing, tracking, taxation, and location, and the same license and tracking record documented conduct that the Controlled Substances Act prohibited at the federal level. The regimes functioned because federal enforcement resources and policy, rather than any change in the underlying prohibition, left room for state systems to operate.

Two Readings of the Same Arrangement

The public health caution reading treated the state regimes as a commercial experiment conducted before the evidence justified the experiment. The National Institute on Drug Abuse, in research summaries and in a letter from Director Nora D. Volkow introducing a marijuana research report, stated that marijuana impaired short term memory and judgment and distorted perception, that impairment made driving dangerous, and that marijuana affected brain systems that continued maturing through young adulthood, so that regular use by adolescents could produce negative and long lasting effects on cognitive development. The same summaries stated that marijuana could be addictive and that frequent use during adolescence carried risks for educational, professional, and social achievement. Congressional testimony submitted for the National Institute on Drug Abuse in 2014 added that the extent to which rising potency might exacerbate established risks remained a question requiring further understanding. That formulation treated potency as a variable moving in one direction while evidence lagged behind the market.

Smart Approaches to Marijuana, founded in 2013 by Kevin Sabet and former Representative Patrick Kennedy, carried the caution argument from laboratory findings to the commercial structure of a legal market. Sabet stated in a 2017 statement for Smart Approaches to Marijuana that a for profit marijuana industry would target poor and young people, and Sabet described the marijuana industry in that statement as the next Big Tobacco, with profit placed ahead of public health and safety. Publications and speeches associated with Sabet and Smart Approaches to Marijuana developed the tobacco comparison into a structural claim. An industry dependent on frequent consumption, on that claim, held an incentive to expand consumption, to market potent products, and to resist restrictions on advertising and availability, and tobacco commercialization showed how such an industry behaved after a legal market gave the industry scale. Licensing and taxation did not answer the central objection in that reading, because licensing normalized a product and taxation gave state governments a revenue interest in sales volume. The caution reading therefore measured a statute by adolescent exposure, by impaired driving, by potency, and by industry incentives.

The federalism and enforcement burden reading began from constitutional structure rather than from pharmacology. Robert A. Mikos of Vanderbilt University Law School, in a policy analysis published by the Cato Institute under the title On the Limits of Federal Supremacy, argued that the anticommandeering principle protected the prerogative of states to legalize activity that Congress had banned, because Congress could not command a state legislature to enact a prohibition and could not order state officials to administer a federal prohibition. The Cato Institute analysis treated that limitation as a consequence of the division of power in the Constitution, under which the federal government enforced federal law with federal resources and a state retained authority over the state criminal code. Ilya Shapiro of the Cato Institute, speaking in 2013, stated that the federal government lacked law enforcement resources to enforce the ban vigorously and lacked ability to marshal social and cultural influences sufficient to secure compliance in states that had chosen a different policy. A prohibition dependent on state officers for ordinary enforcement lost practical force after a state withdrew those officers, and the Constitution prevented Congress from conscripting the officers back.

State officials defending state programs added democratic and evidentiary claims. The National Conference of State Legislatures, in a June 7, 2018 letter supporting the STATES Act, stated that where states had made a policy choice to legalize and regulate marijuana, the federal government should respect state decisions, and the organization maintained that states and localities were best able to determine which policies worked for public safety, health, and economic development. Defenders of state programs pointed to voter margins in initiative states and to legislative deliberation in Vermont as democratic authorization that federal enforcement against state compliant conduct would override without a vote in Congress amending the federal statute. The evidentiary claim held that state variation generated information that a single national rule could not generate. States adopting different tax rates, local control rules, testing regimes, and home cultivation limits produced comparable records on revenue, diversion, youth use, traffic enforcement, and displacement of unlicensed markets, and a national decision taken after observation of those records would rest on evidence about operating markets rather than on projections. On that reading, the anticommandeering structure functioned as a feature of constitutional design, and federal enforcement against state compliant conduct spent scarce resources against the grain of state democratic choices.

Where does the conflict between federal and state marijuana law actually get decided?

The conflict gets decided in federal enforcement choices and in annual appropriations. Courts settled state power to repeal prohibitions and federal power to maintain a prohibition in the Controlled Substances Act. Neither holding displaces the other regime. Annual spending legislation determines whether federal resources pursue state compliant medical conduct.

Preemption doctrine explains why the two regimes could coexist without a judicial endpoint. A state repeal commanded no person to violate federal law, because a person could comply with both sovereigns by refraining from marijuana conduct, and state permission therefore did not make compliance with federal law impossible in the ordinary preemption sense. Federal law remained supreme for federal purposes, so a state license supplied no defense to a federal prosecution. State law remained effective for state purposes, so the federal prohibition supplied no basis for a prosecution that state law had eliminated. Obstacle preemption arguments against particular provisions remained available in individual litigation, but no decision through August 2018 held that the Controlled Substances Act categorically invalidated state regimes as a class. Doctrine thus produced a stable legal answer and an unstable practical arrangement, dependent on whether the federal government chose to spend enforcement resources inside the space that coexistence created.

The courts settled the two constitutional questions that bounded the field and then left the field to politics. Raich, treated in full in the account of federal prohibitions, established federal power to prohibit local cultivation and use, and the anticommandeering decisions in New York in 1992 and Printz in 1997 established state power to repeal a state prohibition and to withhold state enforcement assistance. Neither line required the other sovereign to change course, and enforcement discretion and legislation remained as the only instruments capable of moving the arrangement.

Federal enforcement choices supplied the first instrument, and the appropriations rider, treated in full in the account of the practical regime, supplied the second, with harder legal force and a shorter life. Neither the memoranda nor the rider amended the Controlled Substances Act, and each changed the risk calculation for licensed operators, investors, landlords, and banks without any change in statutory text.

The deciding factor in the coexistence was the annual spending decision, the least durable instrument in the legislative toolkit. An authorizing statute persists until a later Congress repeals or amends the statute, and a judicial holding persists until a court overrules the holding. An appropriations rider persists for a fiscal year. The arrangement in thirty one states by September 2018 rested in significant part on a provision that required affirmative renewal in each spending cycle, that could disappear through inaction or through a conference negotiation, and that protected conduct only against expenditure of federal funds rather than against the underlying prohibition. Stability borrowed year by year described the condition. Each lapse would have exposed state compliant medical conduct to the full prohibition without a vote on legalization itself. A genuine settlement required the action that had not occurred through August 2018: amendment of the Controlled Substances Act by Congress. Rescheduling marijuana from Schedule I to a lower schedule would have altered federal treatment of medical use and research while retaining federal control over distribution. Descheduling would have ended the federal prohibition as a general matter and left states to prohibit, regulate, or permit the substance under state law. A states rights carve out offered a third route, preserving the prohibition in prohibition states while exempting conduct that complied with state law in legalization states. The STATES Act, introduced on June 7, 2018, by Senators Cory Gardner and Elizabeth Warren, proposed that carve out. Earlier rescheduling, descheduling, and narrower medical bills had followed the same path, and none had been enacted through August 2018.

The structural lesson extends beyond marijuana. Appropriations language can perform, temporarily and revocably, work that authorizing statutes have not performed, because a prohibition without funded enforcement operates differently from a prohibition with funded enforcement even when the prohibitory text reads identically in both years. A legislature unable to assemble a majority to repeal a prohibition can sometimes assemble a majority to deny funds for enforcement against a defined class, and the class then lives under a practical permission that no statute granted and no court ordered. The permission lasts only as long as the funding denial lasts, and formal law remains available for revival after a single omitted renewal. A reader measuring a comparable federal state standoff should look first at control over enforcement funding. The text of a prohibition states what a government may punish. An appropriations act, renewed or allowed to lapse annually, often states what a government will punish in practice, and the second statement governed the arrangement through September 2018.

Reading the Coexistence: Recommendations by Audience and a Study Path

A reader approaching the comparison in 2018 gained the most from reading the layers in an order matched to the question at hand, because each layer answered a different question and no layer substituted for another. The student of federalism read the doctrine first, beginning with the anticommandeering decisions in New York v. United States, Printz v. United States, and Murphy v. NCAA, and then turning to section 903 of Title 21 and the preemption analysis that followed from the text. A student who understood commandeering before preemption understood why a state repeal survived even though a federal prohibition also survived, and why the Supremacy Clause governed conflicts between rules for private conduct rather than commands addressed to legislatures. Gonzales v. Raich belonged in the same first pass, because the commerce power holding fixed the reach of the federal prohibition that the anticommandeering cases left untouched.

The staffer working on legislation or oversight read the rider and the renewal calendar first, because the practical position of a medical marijuana program in a listed state in September 2018 depended on language in section 538 of Public Law 113-235 and on successor appropriations acts rather than on the Controlled Substances Act alone. That reader traced the restriction from the enactment of December 16, 2014 through the Consolidated Appropriations Act of March 23, 2018, noted the expiration date of September 30, 2018 attached to the fiscal year, and read United States v. McIntosh for the strict compliance standard that the Ninth Circuit applied. The renewal calendar converted an abstract debate into a dated sequence of committee, floor, and conference action, and a missed renewal determined whether the Department of Justice could spend funds against state compliant medical conduct in the following year.

The researcher read the collateral consequences first, because banking, taxation, immigration, firearms, employment, housing, and research revealed how deeply the Schedule I classification travelled beyond criminal law. Section 280E of the Internal Revenue Code, the Bank Secrecy Act duties described in the FinCEN guidance of February 14, 2014, the firearms prohibition in 18 U.S.C. 922(g)(3), and the immigration provisions in 8 U.S.C. 1182 and 1227 each operated on a federal definition, and each produced consequences in proceedings where no marijuana charge appeared. The journalist read the verdict and the deciding factor first, and then worked backward into doctrine and practice, because a report that began with a state legalization announcement and ended with a federal prohibition statement missed the mechanism that decided daily outcomes between 2014 and 2018. The deciding factor was an annual appropriations decision, and reporting that named that factor explained variation across states and administrations without attributing the variation to a change in the underlying statute.

The closing assessment restated the namable claim that the whole comparison supported. The coexistence of federal prohibition and state legalization between 2014 and September 2018 rested on a rider, not a statute: on an annually renewed appropriations restriction that limited spending against state medical programs, and on revocable enforcement discretion expressed in departmental memoranda that a successor Attorney General withdrew on January 4, 2018. Neither instrument amended the Controlled Substances Act. Neither instrument supplied a permanent defense, a statutory exception, or a rescheduling decision. A settlement required congressional action of a different kind, whether rescheduling, descheduling, or a carve out for state compliant conduct of the kind that the STATES Act proposed on June 7, 2018, and no such measure had been enacted by September 1, 2018. The arrangement was lawful, documented, and fragile, and the fragility followed from the instruments rather than from ambiguity in the doctrine.

A study path for continued work on the comparison began with the series study guide, which placed the federalism questions inside the wider sequence of statutes, cases, and appropriations measures in the series. A reader organizing notes on the cases, the rider renewals, and the collateral regimes kept those materials together in the VaultBook legislation study notebook, where a chronology of enactments and rescissions sat beside the case citations that a comparison of this kind required. A reader testing comprehension of the underlying civics, including the division of power between Congress and state legislatures and the role of appropriations in enforcement, turned to the ReportMedic civics study tool for structured practice on the institutions that the doctrine described. Each resource addressed a different stage of the same work: orientation, organization of the record, and rehearsal of the structure that made a rider, rather than a repeal, the load bearing element of the coexistence in 2018.

Frequently Asked Questions

Q: Can states legalize marijuana under federal drug law?

A state could legalize marijuana under state law on September 1, 2018, in the precise sense that a state legislature or electorate could repeal state prohibitions, narrow state offenses, and create a state licensing system. Legalization in that sense changed state law alone. The Controlled Substances Act continued to prohibit manufacture, distribution, dispensing, and possession of marijuana as a Schedule I substance in every state, and a state license supplied no defense to a federal charge. The two statements coexisted because each sovereign controlled a separate criminal code, separate penalties, and separate enforcement personnel, and because Congress held no power to order a state to maintain a prohibition that the state had chosen to repeal.

Q: Why can federal drug law not force states to criminalize?

The anticommandeering doctrine supplied the reason in the law in force in 2018. In New York v. United States in 1992, the Supreme Court held that Congress could not compel a state legislature to enact a federal regulatory program. In Printz v. United States in 1997, the Court held that Congress could not conscript state officers to administer a federal program. Congress retained full power to regulate private conduct directly, to spend federal funds on federal enforcement, and to offer states lawful incentives for cooperation. The missing power was a power of command over the state as a government, and a state criminal prohibition was an act of state government rather than a federal instrument.

Q: What did Murphy v. NCAA mean for federal drug law?

Murphy v. NCAA, decided on May 14, 2018, held that a federal statute forbidding a state from authorizing sports wagering issued a direct order to state legislatures and violated the anticommandeering rule. Justice Alito, writing for the majority, reasoned that an order forbidding repeal and an order compelling enactment both dictated the content of state law. Applied to drug law, the reasoning meant that Congress could prohibit private marijuana conduct directly under the Controlled Substances Act, enforce that prohibition with federal officers, and preempt conflicting state rules for private parties, while a federal command requiring a state to keep a marijuana prohibition in the state code stood on the forbidden side of the line Murphy drew.

Q: What is the appropriations rider that limits federal drug law enforcement?

Section 538 of the Consolidated and Further Continuing Appropriations Act, 2015, Public Law 113-235, enacted on December 16, 2014, barred the Department of Justice from using appropriated funds to prevent listed states from implementing state laws authorizing medical marijuana. The rider changed no word of the Controlled Substances Act, covered medical programs rather than recreational programs, and lasted for a single fiscal year unless Congress renewed the restriction. In United States v. McIntosh in 2016, the Ninth Circuit held that the rider barred federally funded prosecution of individuals whose conduct fully complied with state medical law, and the court warned that a later Congress could fund such prosecutions again.

Q: Why can marijuana businesses not use banks under federal drug law?

Federal money laundering law and the Bank Secrecy Act generated the banking barrier in 2018, without any prosecution of the business itself. Marijuana revenue counted as proceeds of a federal offense because the Controlled Substances Act prohibited the underlying manufacture and distribution, and sections 1956 and 1957 of Title 18 attached to transactions in such proceeds. Banks also carried duties to maintain anti money laundering programs, to conduct due diligence, and to file suspicious activity reports with the Financial Crimes Enforcement Network. The FinCEN guidance of February 14, 2014 organized reporting for marijuana related businesses around federal enforcement priorities, without amending the statutes that created the exposure, and many institutions declined the accounts after weighing compliance cost and examination risk.

Q: What is 280E in federal drug law?

Section 280E of Title 26, enacted in 1982, denied a deduction or credit for amounts paid or incurred in carrying on a trade or business that consisted of trafficking in a Schedule I or Schedule II controlled substance prohibited by federal or state law. The provision did not deny cost of goods sold, which formed an exclusion from gross receipts rather than a deduction. A state licensed marijuana retailer in 2018 therefore subtracted inventory cost and then lost deductions for rent, wages, utilities, insurance, and marketing that an ordinary retailer claimed, producing taxation on a base close to gross profit. In CHAMP in 2007 and Olive in 2015, courts tested whether a separate non marijuana business existed alongside the trafficking business.

Q: Can you own a gun in a state that legalized under federal drug law?

Under the federal statute in force in September 2018, the answer was no for a person who used marijuana. Section 922(g)(3) of Title 18 made possession, receipt, shipment, or transport of firearms or ammunition unlawful for a person who was an unlawful user of a controlled substance as defined in 21 U.S.C. 802, and section 922(d)(3) barred transfers to such a person. State authorization created no federal category of lawful marijuana use outside federally authorized channels, a position that the Bureau of Alcohol, Tobacco, Firearms and Explosives stated in an open letter dated September 21, 2011, and that ATF Form 4473 restated in a warning added in the October 2016 revision.

Q: Which should a student study first, federal drug law or state legalization?

A student gained the clearest sequence by studying federal drug law first in the order that the doctrine developed: the Controlled Substances Act and the Schedule I classification, the commerce power holding in Gonzales v. Raich in 2005, and then the anticommandeering decisions in New York, Printz, and Murphy. That order separated two questions that political debate merged. The federal cases defined what Congress could prohibit and what Congress could not command a state to prohibit, and state legalization statutes then appeared as exercises of a reserved power over a state code rather than as exceptions inside federal law. The rider, the enforcement memoranda, and the collateral consequences followed in a second pass, as practice layered on doctrine.

Q: Does state legalization protect a person from federal arrest for marijuana?

State legalization provided no protection against federal arrest in 2018. A state statute removed state penalties and directed state officers, and a state license documented compliance with state conditions on cultivation, sale, testing, or possession. Federal officers applied the Controlled Substances Act, under which the same conduct remained a federal offense under sections 841 and 844 of Title 21, with no exception for conduct licensed by a state. Federal enforcement policy and, for medical conduct in listed states, the appropriations rider limited whether federal resources reached state compliant conduct in a given fiscal year. A limit on resources or a statement of priorities differed in kind from a legal defense, and neither converted state permission into federal immunity.

Q: Can a noncitizen be deported for using marijuana in a state where it is legal?

Federal immigration law in 2018 treated marijuana conduct under federal definitions, regardless of state legality. Under 8 U.S.C. 1227(a)(2)(B)(i), a noncitizen convicted of a controlled substance violation after admission was deportable, subject to a textual exception for a single offense involving possession for personal use of 30 grams or less of marijuana. Under 8 U.S.C. 1182(a)(2)(A)(i)(II), a conviction or a formal admission of the essential elements of a controlled substance violation supplied a ground of inadmissibility. A separate provision addressed drug abuse or addiction, and another addressed reason to believe that a person had engaged in illicit trafficking, a category that federal vocabulary applied to manufacture and distribution inside a state licensed business.

Q: Can a federal employee be fired for marijuana use that state law allows?

Federal employment rules in 2018 rested on federal definitions of illegal drug use. Executive Order 12564, signed on September 15, 1986, required federal employees to refrain from illegal drugs on duty and off duty and declared that persons who used illegal drugs were not suitable for federal employment. Marijuana remained a Schedule I controlled substance under federal law, and a state decision to permit use did not remove marijuana from the substances covered by that order. Agency drug free workplace plans supplied procedures for testing in designated positions, referral, discipline, and rehabilitation. The Drug Free Workplace Act of 1988 extended related program obligations to specified federal contractors and grantees, with remedies that included suspension of payments and debarment.

Q: Does the appropriations rider cover recreational marijuana programs?

The rider did not cover recreational marijuana programs. The text of section 538 of Public Law 113-235 addressed state laws that authorized the use, distribution, possession, or cultivation of medical marijuana in the listed states, and the provision contained no reference to recreational or adult use programs. A state system licensing recreational cultivation and retail sale therefore stood outside the spending restriction entirely, however detailed the state testing, tracking, and taxation rules were. Federal treatment of recreational conduct between 2014 and January 2018 depended on prosecutorial guidance, principally the Cole memorandum of August 29, 2013, and after the rescission of that guidance on January 4, 2018, on the general principles of federal prosecution and the judgment of individual United States Attorneys.

Q: Can states be forced to enforce federal marijuana law?

No federal statute in force in 2018 forced a state to enforce the federal marijuana prohibition, and the anticommandeering doctrine barred Congress from imposing such a duty. Printz v. United States held in 1997 that Congress could not command state officers to administer a federal regulatory program, and New York v. United States held in 1992 that Congress could not compel a state legislature to enact one. A state could cooperate voluntarily, accept federal grants with lawful conditions, or join a task force by agreement. A state could also decline to spend state funds or personnel hours on a federal prohibition that state law did not mirror, and the Constitution, as the Supreme Court interpreted the structure in those decisions, left that choice to the state.

Q: What happens to state legalization if Congress stops renewing the rider?

A lapse of the rider in a later fiscal year would leave state legalization statutes fully in force as state law and would restore the ability of the Department of Justice to spend appropriated funds against conduct that the statutes permitted. The Controlled Substances Act required no reenactment, because the rider had amended no part of that Act. In United States v. McIntosh in 2016, the Ninth Circuit observed that prosecutions for conduct committed while a rider remained in force could follow a later lapse, subject to the statute of limitations in 18 U.S.C. 3282. Recreational programs, which the rider never covered, would experience no direct change from a lapse, although the signal sent to banks, investors, and prosecutors would reach both sectors of a state market.

Q: Why does marijuana stay in Schedule I if states have legalized it?

Marijuana remained in Schedule I through August 2018 because placement depended on a federal statutory and administrative process that state legalization did not control. Congress placed marijuana in Schedule I in section 812 of Title 21 in 1970, under criteria requiring a high potential for abuse, no accepted medical use, and a lack of accepted safety for use under medical supervision. The Act provided a scheduling process involving the Attorney General and the Secretary of Health and Human Services, and petitions to move marijuana to a less restrictive schedule were denied across the decades after 1970, including denials issued on August 11, 2016. State findings and state medical programs formed part of the political record, while the legal criteria and the decision rested with federal institutions.

Q: Can a public housing authority evict a tenant for state-legal marijuana use?

Federal housing law in 2018 treated marijuana use as illegal use, because the governing definitions measured legality against federal controlled substance law. Provisions amended by the Quality Housing and Work Responsibility Act of 1998, codified at 42 U.S.C. 13661 and 13662, required owners of federally assisted housing to bar admission of a household in which a member illegally used a controlled substance, and required lease terms under which drug related criminal activity by a tenant, a household member, or a guest furnished cause for termination of tenancy. A Department of Housing and Urban Development memorandum dated January 20, 2011 rejected a reasonable accommodation for medical marijuana in assisted housing. Admission denial was mandatory under the program rules, while termination of an existing tenancy involved discretion under the lease and applicable procedures.

Q: Can a state-legal marijuana business deduct rent and salaries on its federal taxes?

Section 280E of Title 26 barred deductions for rent, salaries, and other ordinary expenses of a business that consisted of trafficking in a Schedule I or Schedule II controlled substance, and courts applied that bar to state licensed marijuana businesses because the trafficking remained prohibited by federal law. The business retained cost of goods sold, so inventory cost reduced gross receipts before the disallowance applied. Litigation turned on allocation and on separateness. In CHAMP in 2007, the Tax Court allowed deductions for a caregiving business that operated as a separate trade or business beside marijuana provision. In Olive, decided by the Ninth Circuit in 2015, complimentary services offered without separate charge formed part of a single marijuana business, and the deductions failed.

Q: Can a driver cross state lines with marijuana bought legally in one state?

Interstate transport of marijuana violated federal law in 2018, regardless of the law at either end of the journey. The Controlled Substances Act prohibited distribution and possession of a Schedule I substance, and transport across a state line also entered a state whose law might prohibit possession outright, exposing the conduct to that state code as well. A purchase lawful under the law of the state of origin supplied no federal authorization and no defense in a destination state, because each state license and each state permission operated only within the legal system that issued the permission. The self contained design of state programs, with tracking, purchase limits, and local taxation, reflected that boundary, since no state instrument purported to create lawful status beyond state borders.

Q: Can colleges that take federal funds allow marijuana on campus?

Institutions receiving federal funds operated under the Drug Free Schools and Communities Act Amendments of 1989, which conditioned federal financial assistance on a program to prevent the unlawful possession, use, or distribution of illicit drugs and alcohol by students and employees, together with standards of conduct prohibiting such conduct on institutional property or at institutional activities. Unlawfulness under that framework followed federal law, under which marijuana was a Schedule I controlled substance in 2018. A state legalization statute therefore did not authorize a campus exception, and institutions in legalization states maintained prohibitions on marijuana in campus policies through August 2018 in order to preserve eligibility for federal funds, including federal student aid programs administered under the Higher Education Act.

Q: What would Congress have to do to settle the conflict between federal and state marijuana law?

A durable settlement in 2018 required an Act of Congress amending the Controlled Substances Act, because neither a state statute, nor an enforcement memorandum, nor an appropriations rider altered the federal prohibition. Congress held several routes. Rescheduling marijuana under the procedures in 21 U.S.C. 811 would move the substance to a lower schedule and change federal treatment of medical use and research while retaining federal controls. Descheduling would remove marijuana from the schedules and end the general federal prohibition, leaving states to prohibit, regulate, or permit the substance. A carve out would preserve the prohibition in states that retained bans while exempting conduct in compliance with state law elsewhere, the approach that the STATES Act, introduced on June 7, 2018, proposed and that no enacted law had adopted by September 1, 2018.
