Legal history of cannabis in the United States [SEP] Introduction
The legal history of cannabis in the United States pertains to the regulation of cannabis (legal term marijuana or marihuana) for medical, recreational, and industrial purposes in the United States. Increased restrictions and labeling of cannabis as a poison began in many states from 1906 onward, and outright prohibitions began in the 1920s. By the mid-1930s cannabis was regulated as a drug in every state, including 35 states that adopted the Uniform State Narcotic Drug Act. The first national regulation was the Marihuana Tax Act of 1937. Cannabis was officially outlawed for any use (medical included) with the passage of the 1970 Controlled Substances Act (CSA).
