In 1970, the Controlled Substances Act (CSA) established a classification system for all narcotic and psychotropic drugs. Congress determined that each drug would be assigned to one of five schedules depending on safety and medical efficacy. A commission was appointed to figure out how to schedule marijuana. While this topic was debated, marijuana was temporarily placed in the most restrictive classification. This classification suggested a “high potential for abuse” and “no currently accepted medical use.” The final report called for decriminalizing marijuana and eliminating it from the scheduling system altogether. President Nixon rejected these findings, and to this day, marijuana remains in the most restrictive classification. During the late 1980’s, a large number of gay man in San Francisco were dying from AIDS-related complications. They were able to find relief of their symptoms by taking cannabis. A number of police raids and arrests were deliberately targeted at this group of men, leading to local outrage. This publicity helped to promote public support for revisiting the state’s marijuana laws. It took nearly twenty years, however, for voters in California to approve the Compassionate Use Act, which exempts medical marijuana patients and caregivers from criminal prosecution. Over the proceeding fifteen years, 16 more states have also passed medical marijuana legislation. Colorado and Washington voted to become the first two states to legalize marijuana for recreational use. There are currently 29 states that have passed medical marijuana legislation, with eight of these legalizing recreational use and 15 more permitting just the use of the non-psychoactive cannabinoid, cannabidiol (CBD). Despite never causing a single overdose-related death, cannabis is still classified as a Schedule I drug.
