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 (PL. 91-513). For background on how marijuana came to be placed on
Schedule I, see Appendix B of CRS report, The Marijuana Policy Gap and the Path Forward.
The Schedule I status of marijuana means that the substance is strictly regulated by federal authorities.
Yet, over the last several decades, most states and territories have deviated from across-the-board
prohibition of marijuana, and now have laws and policies allowing for some cultivation, sale, distribution,
and possession of marijuana.

marijuana policies are highlighted below.
 Institutions of Higher Education (IHEs). It has been reported that IHEs may decline to permit
research on marijuana on their campuses, because doing so may put them at risk of losing federal
funds. An IHE's policy prohibiting marijuana on campus may also affect students for whom their
states have authorized the use of medical marijuana. Under the Higher Education Act of 1965,
each IHE must adopt a program to prevent the use of illicit drugs and alcohol and annually
distribute standards of conduct that prohibit the unlawful possession, use, or distribution of illicit
drugs and alcohol on the institution's property or as part of any of its activities and that describe
applicable legal sanctions.

Treasury Department's Financial Crimes Enforcement Network (FinCEN) on how financial
