Arizona Cannabis FAQ

Common questions about Arizona marijuana laws, Prop 207, and the 2026 repeal initiative.

Yes. As of May 2026, cannabis is legal for both medical and recreational use for adults 21 and older. However, this status could change depending on the outcome of the November 2026 election.

It is a voter-led effort that seeks to overturn the 2020 legalization law, Prop 207. If passed, it would ban commercial recreational sales and dispensaries, though it currently contains provisions that might allow limited home cultivation to continue.

Adults can legally possess up to 1 ounce of flower, with no more than 5 grams being concentrate. Medical patients can possess up to 2.5 ounces every two weeks.

No. It changes how the IRS treats cannabis businesses and acknowledges the medical value of the plant, but it does not make recreational use legal at the federal level. Arizona's local laws still govern who can buy and sell.
