Arizona dispensary rules: what every patient should know.

Even with recreational cannabis legal in Arizona, the state has strict rules about possession, consumption, sharing, and where you can use it. As a medical patient, you have more rights than recreational users, but also more responsibility. Here's the complete guide to staying compliant and safe.

Possession limits

Medical cardholders

• 2.5 ounces of cannabis at any time
• Up to 12.5 grams of cannabis concentrate (extracts, oils, wax)
• Includes products in your home, car, and on your person

Recreational users (21+)

• 1 ounce of cannabis at any time
• Up to 5 grams of cannabis concentrate

Going over these limits — even slightly — can result in a felony charge. Count your purchases carefully. A 1/8 oz (3.5g) is one purchase; a quarter (7g) is two purchases; an ounce (28g) is the maximum for rec users.

Where you can and can't use cannabis

Legal consumption locations

• Your home (or any private residence where you have permission)
• Private property with the owner's consent
• Licensed cannabis consumption lounges (rare in AZ, but a few exist in Phoenix and Tucson)

Illegal consumption locations

• Public spaces: parks, sidewalks, streets, beaches
• Restaurants, bars, and businesses (no public consumption)
• Federal land: national parks, forests, monuments, military bases, post offices, federal buildings
• Schools and universities (any educational facility, K-12 or college)
• Public transportation: buses, light rail, taxis, rideshare (without explicit driver consent)
• Workplace (even if you have a medical card, employers can restrict)
• Within 300 feet of a school, park, or public building (some cities)

Arizona's smoke-free laws apply to cannabis too. The Arizona Smoke-Free Act prohibits smoking in most indoor public places, and many cities have additional outdoor restrictions.

Sharing cannabis

Under Arizona law, sharing medical cannabis is illegal — even with another registered patient. The only exception is designated caregivers administering to their registered patient.

This means:

• You cannot give cannabis to a friend, even if they also have a card
• You cannot give cannabis to a family member, even in your own home
• You can give cannabis away only if you are the designated caregiver for a minor or adult who cannot self-administer

This is a frequent source of legal trouble. Be strict about this rule.

Driving and cannabis

Arizona's zero-tolerance law

Arizona has some of the strictest THC-impaired driving laws in the country. Under ARS §28-1381:

• Any amount of THC in your system while driving can result in a DUI charge
• Even medical cardholders are not exempt from DUI laws
• Penalties include fines ($1,000+), license suspension, possible jail time, and ignition interlock device

Practical rules

• Don't drive within 4–6 hours of smoking or vaping
• Don't drive within 8–10 hours of an edible (THC can remain detectable in blood for 24+ hours for regular users)
• Keep cannabis in a sealed container in your trunk (not the cabin) when transporting
• Never consume cannabis in a parked car on a public road (this can be charged as DUI in some cases)

Growing cannabis at home

Medical cardholders

• Up to 12 plants at your primary residence
• Maximum 6 mature (flowering) plants at any time
• Plants must be in a locked, enclosed space not visible from public view
• If renting, landlord permission is required (and may prohibit it in the lease)

Recreational users

No home cultivation allowed under Prop 207.

Dispensary etiquette and rules

At the dispensary

• Have your AZ MMJ card and valid photo ID ready
• Most dispensaries are cash-only (with on-site ATMs, usually with fees)
• No smoking or consumption on the premises
• No photography inside the building (most dispensaries prohibit it)
• No weapons of any kind
• Children may be allowed in the waiting area with a parent but typically not in the sales area
• Be respectful to budtenders — they're trained to help but can't override AZ law

Etiquette tips

• Tip your budtender in cash if they were helpful (common practice, $1-5)
• Don't smell strongly of cannabis when entering (especially around children in the waiting area)
• Have your questions ready — the budtender can spend more time helping informed customers
• Don't be afraid to say "I don't know" — budtenders appreciate honesty over bluffing
• Ask to see the COA if you want to verify a product's potency or safety

Out-of-state travel with your AZ card

Arizona has medical marijuana reciprocity with several other states (NV, MI, ME, MA, RI, NM, and others). When traveling:

• Bring your AZ digital card + photo ID
• Check the destination state's possession limits (often lower than AZ's 2.5 oz)
• Don't cross non-reciprocity states with cannabis (federal jurisdiction applies on most highways)
• Never fly with cannabis (TSA is federal)
• Some states require advance registration — check before travel

For full reciprocity details, see our reciprocity guide.

Workplace rules

The Arizona Medical Marijuana Act (ARS §36-2814) provides employment protections, but they're limited:

• Employers cannot discriminate against you solely for your cardholder status
• But employers can prohibit use at work and discipline for on-the-job impairment
• Employers can require pre-employment drug tests and reject positive THC results (most do)
• Safety-sensitive positions (DOT, federal jobs, law enforcement) typically have zero-tolerance policies
• You have no protection if you test positive at work

If you're subject to workplace testing

• Most regular users will test positive for 30+ days after last use (urine tests)
• Hair tests can detect use for 90 days
• If you have a workplace test coming up, take a tolerance break well in advance (see our guide)
• CBD-only products are less likely to trigger positive THC tests (but not zero risk — full-spectrum CBD can contain trace THC)

Housing and landlord rules

Federal housing

Cannabis use (even medical) is illegal in federally subsidized housing. Public housing authorities can and do evict for cannabis use or possession, regardless of medical card status.

Private rentals

Arizona's medical marijuana law does not override private lease agreements. If your lease prohibits smoking or cannabis use, you're bound by it. Some landlords are cannabis-friendly; many are not. Read your lease carefully.

Homeowners

You can use and grow cannabis in your own home. HOA rules may still apply — some HOAs prohibit outdoor smoking or cultivation. Check your CC&Rs.

Travel within Arizona

You can travel with your medical cannabis anywhere in Arizona, including:

• In your car (sealed container, trunk preferred)
• On public transportation (technically allowed but discreet; rideshare drivers may refuse)
• To a dispensary in another city (your card works at any AZ dispensary)
• On hiking trips (but consumption is not allowed on federal land — including most of Arizona's national parks, forests, and monuments)

When out-of-state visitors ask

Out-of-state medical patients cannot use their home-state cards in Arizona dispensaries (despite reciprocity, AZ doesn't accept other states' cards at dispensaries — only AZ-registered patients can purchase). But AZ dispensaries welcome them as recreational customers if they're 21+ with a valid ID.

Penalties summary

Violation	Penalty
Possession over 2.5 oz (medical)	Class 4–6 felony, 1–3.75 years prison, $150,000 fine
Possession under 2.5 oz without card	Class 6 felony, 0.5–2 years
Consuming in public	Civil violation, $100–300 fine
Possession on K-12 school grounds	Class 6 felony
Sharing cannabis (any amount)	Class 6 felony
Driving under influence (THC)	DUI, $1,000+ fine, license suspension, possible jail
Growing without card	Class 5 felony, 9 months–2 years
Growing with card but not in locked space	Civil violation, $750 fine
Possession on federal land	Federal misdemeanor or felony, federal charges

Common-sense rules

• Always carry your card and ID when you have cannabis with you
• Keep cannabis in its original dispensary packaging when possible (clearly legal source)
• Don't consume around children, even in your own home if there's any risk of secondhand exposure
• Don't combine cannabis with alcohol and drive (impaired is impaired, plus alcohol amplifies impairment)
• If you're unsure about a specific situation, err on the side of caution — the legal consequences are severe

When in doubt

The laws are complex and enforcement varies. For non-medical questions, the Arizona Department of Health Services (azdhs.gov) has the official rules. For specific legal questions (employment, housing, criminal), consult a licensed Arizona attorney familiar with cannabis law.
