Cannabis Policy: Federal-State Conflicts and Reform Proposals

The Controlled Substances Act of 1970 established the current framework for federal drug regulation, creating five schedules of controlled substances based on their potential for abuse, accepted medical use, and safety profile. Marijuana was placed in Schedule I alongside heroin and LSD, reflecting the prevailing view at the time that it had no legitimate medical application. Federal marijuana enforcement was a priority throughout the War on Drugs era, with Congress enacting mandatory minimum sentences for drug trafficking offenses.

State marijuana legalization began with California's Proposition 215 in 1996, which authorized medical marijuana use. Colorado and Washington became the first states to legalize recreational marijuana through ballot initiatives in 2012. Since then, the pace of state legalization has accelerated, creating a growing conflict between state and federal law. Federal enforcement policy has evolved from the Cole Memorandum (2013), which deprioritized federal prosecution of state-legal marijuana activity, to its rescission in 2018, to subsequent congressional appropriations riders prohibiting DOJ from spending funds to interfere with state medical marijuana programs.

Under the CSA, the manufacture, distribution, and possession of marijuana are federal crimes punishable by significant fines and imprisonment. Simple possession carries penalties of up to one year imprisonment for a first offense. Trafficking penalties vary based on quantity, with cultivation of 100 or more plants carrying a mandatory minimum of five years. Section 280E of the Internal Revenue Code prohibits businesses trafficking in Schedule I or II controlled substances from deducting ordinary business expenses, substantially increasing the effective tax rate for state-legal cannabis businesses.

The appropriations rider known as the Rohrabacher-Blumenauer amendment has been included in annual spending bills since 2014, prohibiting DOJ from using funds to prevent states from implementing their own medical marijuana laws. However, this protection applies only to medical programs and must be renewed annually. No similar statutory protection exists for recreational marijuana programs, though the DOJ has generally not prioritized prosecution of state-legal recreational marijuana activity in recent years.

Congressional options range from maintaining the status quo to comprehensive federal legalization. The SAFE Banking Act would prohibit federal banking regulators from penalizing financial institutions for providing services to state-legal cannabis businesses, addressing one of the industry's most acute operational challenges. The MORE Act would deschedule marijuana entirely, expunge certain federal marijuana convictions, and impose a federal excise tax. The STATES Act would amend the CSA to exempt state-legal conduct from federal prohibition.

Rescheduling marijuana to Schedule III, as proposed by the DEA, would maintain federal control over marijuana but reduce criminal penalties, eliminate Section 280E's tax penalty for cannabis businesses, and potentially allow FDA-approved marijuana products. However, rescheduling would not legalize recreational or medical marijuana at the federal level, and the relationship between a Schedule III classification and state legalization programs would present novel regulatory questions. Some advocates prefer descheduling, which would remove marijuana from the CSA entirely and treat it more like alcohol and tobacco.

The DEA's proposed rescheduling rule has generated significant public comment and administrative proceedings. State legalization continues to expand, with additional states considering ballot initiatives and legislative proposals. The cannabis industry has advocated for federal banking reform and resolution of the Section 280E tax issue. Congressional activity includes hearings on the impacts of federal-state conflicts, the public health implications of marijuana use, and the economic effects of legalization. The issue intersects with broader criminal justice reform discussions, including retroactive relief for individuals with federal marijuana convictions.
