Arizona’s medical marijuana program did not come into effect until November of 2010, despite previously being approved in 1996 and 1998. Ballot Proposition 203 was approved by 50.13% of Arizona voters, effectively removing all state-level penalties on the use, possession and cultivation of marijuana, by patients who have been issued with a “written or oral recommendation”, by their primary care physician, stating that he or she “would benefit from medical marijuana.”
