The federal government regulates drugs through the Controlled Substances Act. 21 U.S.C. § 811 does not recognize the difference between medical and recreational use of marijuana. Any use of marijuana is illegal under federal law. Federal law treats marijuana as a controlled substance. It does not distinguish marijuana from other drugs such as cocaine and heroin. Under the Controlled Substances Act, marijuana is classified as a Schedule I drug, which means that the federal government views marijuana as highly addictive and having no medical value. Doctors may not prescribe marijuana for medical use under federal law.
