Controlled Substances Act

The 1970 US federal law that classifies cannabis as a Schedule I substance, forming the basis of federal prohibition.

The Controlled Substances Act (CSA) is the 1970 US federal law that established the framework for regulating drugs and other substances in the United States. Under the CSA, cannabis was placed in Schedule I, the most restrictive category, where it has remained for over 50 years despite extensive evidence of medical value and a strong safety profile.

Structure of the CSA

The CSA organizes controlled substances into five schedules based on their potential for abuse, accepted medical use, and safety profile. Schedule I (cannabis, heroin, LSD) is deemed to have no medical use. Schedule II (cocaine, fentanyl, methamphetamine) includes substances with medical use but high abuse potential. Schedules III through V contain progressively less restricted substances. The scheduling determines criminal penalties, research regulations, prescribing authority, and manufacturing controls. Cannabis's placement alongside heroin in Schedule I has been a cornerstone of federal prohibition.

Impact on Cannabis

The CSA's classification of cannabis has had profound consequences. It created federal-state conflicts as states legalize, restricted scientific research by requiring DEA approval for cannabis studies, subjected cannabis businesses to Section 280E tax penalties, blocked federal banking access for the industry, and prevented VA doctors from recommending cannabis to veterans. Rescheduling or descheduling cannabis under the CSA would address many of these issues, and the process to do so was underway as of 2024. The CSA remains the foundational legal barrier to full cannabis normalization in the United States.
