FAQ

Common questions

Is marijuana legal in Arizona?

Recreational marijuana is legal in Arizona. Medical marijuana is legal.

Is THCA legal in Arizona?

Restricted, with material enforcement risk. Arizona's hemp statute at A.R.S. §3-311 adopts the federal 0.3 percent delta-9 cultivation standard, but subsection (5) excludes ingestible hemp products from authorized hemp uses except food made from sterile hemp seed or hemp seed oil.

Is delta-8 THC legal in Arizona?

Illegal outside the ADHS-licensed cannabis channel. Arizona Attorney General Opinion I24-005 (March 11, 2024) concluded that hemp-synthesized intoxicants including delta-8 THC are Schedule I controlled substances under Arizona law and may be sold only by licensed marijuana establishments.

Is hemp-derived delta-9 THC legal in Arizona?

Illegal outside the ADHS-licensed cannabis channel. Arizona Attorney General Opinion I24-005 (March 11, 2024) addressed delta-8 directly but the opinion's reasoning, and its express reference to "Delta-9 THC and similar derivatives," extends to hemp-derived delta-9 edibles, beverages, and tinctures.

Under Proposition 207 (Smart and Safe Arizona Act), A.R.S. § 36-2852 permits adults 21+ to possess and cultivate up to six marijuana plants per adult (twelve per household) and to transfer up to one ounce or six plants to another adult 'without remuneration' — seeds are marijuana under A.R.S. § 36-2850. Licensed marijuana establishments may sell seeds, though in practice most Arizona consumers buy from seed banks, which is lawful for personal cultivation. Hemp cultivation and hemp nursery/propagation activity require licensing from the Arizona Department of Agriculture under A.R.S. § 3-311 et seq., but consumer possession of viable seed is not restricted.

Key law:
A.R.S. §§ 36-2850, 36-2852 (Prop 207); A.R.S. § 3-311 et seq.
