In the United States, cannabis is legal in 38 of 50 states for medical use and 24 states for recreational use. At the federal level, cannabis is classified as a Schedule I drug under the Controlled Substances Act, determined to have a high potential for abuse and no accepted medical use, prohibiting its use for any purpose. Despite this prohibition, federal law is generally not enforced against the possession, cultivation, or intrastate distribution of cannabis in states where such activity has been legalized. Beginning in 2024, the Drug Enforcement Administration has initiated a review to potentially move cannabis to the less-restrictive Schedule III.
