Is Weed Legal in Arizona?

Is weed legal in Arizona?

Arizona allows both recreational and medical cannabis. Adult-use possession, sale, and limited home cultivation became legal in 2020 under Proposition 207; medical use has been legal since voters passed Proposition 203 in 2010. Both markets are licensed and regulated by the Department of Health Services. Hemp cultivation is legal under a USDA-approved state program run by the Department of Agriculture. A 2024 Arizona Attorney General opinion (I24-005) says delta-8 and other hemp-made intoxicating products may be sold only by licensed cannabis sellers, not by smoke shops or convenience stores.

Federal hemp change: from December 11, 2026 the federal definition of hemp counts total THC, including THCA, and final hemp products with more than 0.4 mg of total THC per container are no longer hemp; products with cannabinoids the plant cannot naturally produce stop counting as hemp on November 12, 2026. What changes, state by state (P.L. 119-37 § 781; P.L. 119-103 § 2019).

Recreational (adult-use) cannabis

Recreational marijuana has been legal in Arizona since Proposition 207 passed in November 2020, with possession and home growing legal from November 30, 2020. Adults 21+ may possess one ounce, buy from ADHS-licensed marijuana establishments, and grow up to six plants at home (twelve per household). A 16% excise tax applies on top of standard sales tax.

Medical marijuana program

Arizona's Medical Marijuana Program, created by 2010's Proposition 203, lets patients diagnosed with a qualifying debilitating condition (cancer, HIV/AIDS, PTSD, severe and chronic pain, glaucoma, and others) register for a card after a physician's written certification. Cards cost $150 ($75 for SNAP recipients) and are valid two years. Patients may possess up to 2.5 oz and buy up to 2.5 oz every 14 days, use a designated caregiver serving up to five patients, and grow at home only if living more than 25 miles from a dispensary.

Possession limits

Adults 21 and older may possess up to one ounce of marijuana, of which no more than five grams may be concentrate. Registered medical patients may possess up to two and one-half ounces of usable marijuana (and may buy no more than that from dispensaries in any 14-day period), plus twelve plants if approved to grow. Possessing more than one ounce but no more than 2.5 ounces (up to 12.5 grams of concentrate) is a petty offense; larger amounts escalate to felonies based on weight.

Buying cannabis

Adults 21 and older may buy up to one ounce of marijuana (no more than five grams as concentrate) per transaction at a licensed adult-use establishment after showing government-issued ID. Registered medical patients purchase against their 2.5-ounce-per-14-day allowance at ADHS-licensed nonprofit dispensaries. Visiting out-of-state medical cardholders get limited recognition but cannot buy at Arizona dispensaries as patients.

Growing cannabis at home

Adults 21 and older may grow up to six marijuana plants at their primary residence, or up to twelve where two or more adults 21+ live there, in a locked area not visible from public view. Medical patients may grow up to twelve plants in an enclosed, locked facility only if they live more than 25 miles from a licensed dispensary, and a designated caregiver may cultivate under the same 12-plant rule for a patient.

Penalties

Simple possession of an ounce or less by an adult is legal; 1 to 2.5 ounces is a petty offense with up to a $300 fine; larger amounts become felonies scaling with weight up to $150,000 in fines and years in prison. Sale, unlicensed cultivation, and trafficking are felonies with sentences that escalate by weight. Driving while impaired to the slightest degree by marijuana is DUI, at least a class 1 misdemeanor; marijuana metabolites in the body alone are not enough for a DUI charge. People with past records for 2.5 ounces or less, up to six plants at home, or paraphernalia may ask a court to expunge them.

Product rules: CBD, delta-8 and hemp

Marijuana products include flower, concentrate, and infused products such as edibles, ointments, and tinctures. Edible THC content is capped at 10 mg per serving and 100 mg per package, and multi-serving products must be scored and evenly dosed. Products must be sold in child-resistant packaging with labels showing potency, batch number, ingredients, and a required health warning, plus a QR code linking to lab results and source information.

Federal hemp change: from December 11, 2026 the federal definition of hemp counts total THC, including THCA, and final hemp products with more than 0.4 mg of total THC per container are no longer hemp; products with cannabinoids the plant cannot naturally produce stop counting as hemp on November 12, 2026. What changes, state by state (P.L. 119-37 § 781; P.L. 119-103 § 2019).

Cannabis taxes

Adult-use retail marijuana sales carry a 16% state excise tax on top of standard state and local sales (transaction privilege) tax; the excise tax itself is not subject to further local tax. Medical marijuana dispensed to registered patients is exempt from the 16% excise tax but still subject to ordinary sales tax. Excise revenue funds the Smart and Safe Arizona Fund, split among community colleges, police and fire, highways, justice reinvestment, and enforcement.

Cannabis business licensing

The Department of Health Services licenses marijuana establishments, which may combine retail, cultivation, and manufacturing under one license. New establishment licenses are capped at roughly one per ten registered pharmacies plus 26 social-equity licenses, awarded by random selection; license fees run $25,000 initial and $5,000 renewal. Lab testing is mandatory, and localities may zone, cap, or ban marijuana businesses, though establishments generally may not sit within 500 feet of a school or child care facility.
