The Short Answer: Yes, Cannabis Is Legal
Cannabis is fully legal in Arizona for adults 21 and older. On November 3, 2020, Arizona voters approved Proposition 207 — the Smart and Safe Arizona Act — with 60% support, a margin of more than 650,000 votes. The law took effect on November 30, 2020, and the first recreational sale happened on January 22, 2021 — just 8 weeks after the vote, making it the fastest recreational launch in U.S. history.
Arizona's cannabis story stretches back further. Proposition 203 established the medical program in 2010 by the thinnest margin in American marijuana ballot history — 4,341 votes out of 1.67 million cast. In between, Proposition 205 tried to legalize recreational in 2016 and failed by less than 3 points, partly due to a $500,000 contribution from fentanyl manufacturer Insys Therapeutics.
