Weed Laws and Regulations for Arizona

Arizona has become a major hub for cannabis in the United States, with both medical marijuana and recreational cannabis now legal under state law. Since voters approved the Smart & Safe Arizona Act, dispensaries have opened across the state, giving adults and qualifying patients access to a regulated market. However, the rules can be complex, and penalties still exist for misuse. This guide explains everything you need to know about Arizona cannabis laws and regulations, from legal history and oversight to safety standards and visitor rules.

Is Weed Legal in Arizona?

Yes. Arizona has legalized both medical and recreational (adult-use) marijuana. Medical use was legalized first via Proposition 203 in 2010. Later, in 2020, voters passed Proposition 207, also called the Smart & Safe Arizona Act, legalizing recreational use for adults 21 and older.

Purchase & Possession Limits

Here are the rules for how much cannabis you may possess or purchase under both recreational and medical programs:

Recreational (Adults 21+)

• You may possess up to 1 ounce (~28 grams) of marijuana at a time.
• Of that, no more than 5 grams may be concentrates (extracts, wax, etc.).
• Home grow: up to 6 plants per adult, maximum 12 per household.

Medical Use

• Qualified patients may possess up to 2.5 ounces in any 14 days.
• Patients living more than 25 miles from a dispensary may grow up to 12 plants.

Note: Medical limits are generally higher than recreational limits, particularly for possession and cultivation.

Places Where Use Is Prohibited

• Public places such as sidewalks, parks, and streets are off-limits.
• In vehicles or while driving — DUI laws apply.
• Near schools or playgrounds where minors are present.
• On federal land or reservations (federal law still prohibits cannabis).
• At dispensaries — consuming on the premises is prohibited (Flowhub overview).

Taxes on Cannabis

Arizona imposes taxes on cannabis that differ for recreational and medical users:

• Recreational cannabis: 16% excise tax on retail sales.
• Recreational sales are also subject to the state and local Transaction Privilege Tax (TPT).
• Medical cannabis: exempt from the 16% excise tax, but standard sales taxes apply.

Example Tax Calculations

Example: $100 purchase price comparison.

• Recreational: 16% excise = $16, +7.8% sales = $7.80 → total $23.80 → final $123.80.
• Medical: Excise $0, +7.8% sales = $7.80 → total $7.80 → final $107.80.

Actual totals vary by local tax rates — always check your jurisdiction.

Consumption Locations

• Allowed: private property with owner’s permission.
• Public lounges are not yet common; few jurisdictions allow limited consumption venues or events.

Cultivation Rules

• Recreational: Adults 21+ may grow up to 6 plants (12 per household) in a locked, enclosed area not visible to the public.
• Medical: Patients 25+ miles from a dispensary may apply to grow up to 12 plants.

Medical Marijuana Program

• Qualifying conditions: Patients must meet medical criteria defined under Arizona law.
• Purchase limit: 2.5 ounces every 14 days (tracked by dispensaries).
