The use, sale, and possession of all forms of cannabis in the United States is illegal under federal law. As a Schedule I drug under the federal Controlled Substances Act of 1970, cannabis is considered to have "no accepted medical use" and have a high potential for abuse and physical or psychological dependence. Cannabis use is illegal for any reason, with the exception of FDA-approved research programs. However, individual states have enacted legislation permitting exemptions for various uses, mainly for medical and industrial use.
