Medical Marijuana in States Prior to Passage of California's Prop 215
Beginning in 1978, thirty-seven states enacted some form of medicinal cannabis legislation other than effective laws. These include:
Therapeutic Research Programs (state-run therapeutic research programs, not operable because of federal obstruction): Alabama, California, Georgia, Illinois, Massachusetts, Minnesota, New Jersey, New York, South Carolina, Texas.
Symbolic Prescriptions (patients allowed to possess cannabis only if obtained through prescription, not operable because the CSA bars physicians from writing prescriptions for Schedule I drugs): Arizona, California, Connecticut, District of Columbia, Iowa, New Hampshire, Tennessee, Virginia, Wisconsin.
State Rescheduling (not operable because federal scheduling supersedes state schedules): Alaska, Iowa, Montana, Tennessee, and the District of Columbia.
Non-binding Resolutions Urging Federal Rescheduling: California, Michigan, Missouri, New Hampshire, New Mexico, Rhode Island, Washington.
