Passed by Congress in 1973, the Controlled Substance Act (CSA) established a single classification plan for narcotic & psychotropic drugs. The plan was to assign each drug one of several schedules according to safety & 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 sited in the most restrictive classification. This classification was reserved for drugs with a high potential for abuse & no adequate medical use. The final report from the Shafer Commission called for marijuana to be decriminalized & removed from the scheduling plan altogether. President Nixon rejected this recommendation; By the late eighties, gay men in San Francisco were dying in alarming numbers from Aids-related problems. Aids sufferers found some relief from the use of cannabis. A string of police raids & arrests concentrated on this helpless segment of the population & led to public outrage. This began the outcry for change in the state’s marijuana laws. Unfortunately, the change took a entirely long time. Finally, in 1996, California voters approved the Compassionate Use Act. Medical marijuana patients & caregivers were then exempt from criminal prosecution, over the next fifteen years, an additional sixteen states passed medical marijuana legislation. CO & Washington were the first numerous states to legalize recreational marijuana. As it stands, 29 states have passed medical marijuana legislation, with eight legalizing recreational use, & fifteen allowing strictly the use of cannabidiol (CBD), a non-psychoactive form of cannabis. At the federal level, but, cannabis remains in the most restrictive classification.
