CRS INSIGHT Prepared for Members and Committees of Congress INSIGHTINSIGHTi i The Schedule I Status of Marijuana Updated March 25, 2022 The Controlled Substances Act (CSA) places various substances in one of five schedules based on their medical use, potential for abuse, and safety or risk for dependence. The five schedules are progressively ordered with Schedule V substances regarded as the least dangerous and addictive and Schedule I substances considered the most dangerous and addictive. Schedule I substances are considered to have a “high potential for abuse” with “no currently accepted medical use in treatment in the United States.” The CSA prohibits the manufacture, distribution, dispensation, and possession of Schedule I substances except for federal government-approved research studies. Marijuana is listed as a Schedule I controlled substance under the CSA, and has been on Schedule I since the CSA was enacted in 1970 (P.L. 91-513).

The Schedule I status of marijuana means that the substance is strictly regulated by federal authorities
