Passed by Congress in 1969, the Controlled Substance Act (CSA) established a single classification method for narcotic and psychotropic drugs. The method was to assign each drug one of five schedules according to safety and medical effectiveness. A commission was appointed by Congress to decide how to schedule marijuana. This group became known as the Shafer Commission. Until the classification could be determined, marijuana was temporarily placed in the most restrictive classification. This classification was reserved for drugs with a high potential for abuse and no reasonable medical use. The final report from the Shafer Commission called for marijuana to be decriminalized and removed from the scheduling method altogether. President Nixon rejected this recommendation. By the late eighties, gay men in San Francisco were dying in horrifying numbers from Aids-related concerns. Aids sufferers found some relief from the use of cannabis. A string of police raids and arrests concentrated on this helpless segment of the population and led to public outrage. This began the outcry for change in the state’s marijuana laws. Unfortunately, the change took a particularly long time. Finally, in 1996, California voters approved the Compassionate Use Act. Medical marijuana patients and caregivers were then exempt from criminal prosecution, over the next fifteen years, an additional sixteen states passed medical marijuana legislation. CO and WA were the first 2 states to legalize recreational marijuana. As it stands, 29 states have passed medical marijuana legislation, with eight legalizing recreational use, and fifteen allowing strictly the use of cannabidiol (CBD), a non-psychoactive form of cannabis. At the federal level, however, cannabis remains in the most restrictive classification.
