2010: Proposition 203 legalized the use of medical marijuana.

After three failed attempts to legalize medical marijuana in the state of Arizona, voters accepted and passed Proposition 203 in November of 2010. Arizona became the 15th state to legalize medical marijuana. In November of 2016, Proposition 205, known as the Arizona Marijuana Legalization Initiative, was rejected by voters. This would have allowed for persons of at least 21 years of age to possess and use up to one ounce of marijuana.
