1) Quick snapshot — the essential rules (short version) Weed in Phoenix

• Adults 21 and older may possess, purchase, transport, or process up to 1 ounce (28 g) of cannabis, of which no more than 5 grams may be concentrate. (Arizona Department of Revenue)
• Adults may grow up to 6 plants at a residence; if two or more adults (21+) live together the total may be up to 12 plants at that residence. Cultivation must be in an enclosed, lockable area not visible to the public. (Arizona Courts)
• Medical marijuana patients have separate allowances (e.g., the state statutes define an “allowable amount” for qualifying patients — see official rules). (Arizona Legislature)
• Public consumption is illegal. Cannabis may only be consumed on private property with the owner’s permission; social consumption lounges are not broadly legal under state law (stay mindful of local ordinances). (Cannabis Cactus)
• Driving under the influence of cannabis is illegal — Arizona law allows prosecutors to prove impairment to the “slightest degree” and DUI penalties can be severe. Recent court decisions have complicated reliance on THC presence alone, but impaired driving remains prohibited. (Salwin Law Group)

2) The law in depth: Prop 207 and state statutes Weed in Phoenix

What Proposition 207 did
Proposition 207 (the Smart and Safe Arizona Act) legalized adult-use cannabis for Arizonans 21+ and created a regulatory framework for sales, possession, and cultivation. It also included mechanisms for petitioning courts to seal or expunge past marijuana convictions that would now be legal under the new regime. For a state-run summary and the official expungement forms, see the Arizona Courts resources. (Arizona Courts)

Possession & purchase limits
Under state law adults 21+ may possess up to one ounce of marijuana (28 g), and no more than 5 grams of that may be concentrate. Retail transactions for adult-use are capped similarly (dispensaries track purchases). Medical patients have a higher “allowable amount” under the Medical Marijuana Act (see state statutes and ADHS rules). (Arizona Department of Revenue)

Home cultivation
Adults may grow cannabis at their residence, but with strict limits: 6 plants per adult, with a maximum of 12 plants per residence where two or more adults live. Cultivation must occur in an enclosed, lockable area that prevents access by minors and is not visible from public spaces. Municipalities may adopt their own rules within some constraints, so check Phoenix city codes or homeowner association rules before starting a grow. The text of the statute spells out the location and security requirements. (Arizona Courts)

Public consumption & private clubs
State law does not permit public smoking/vaping of cannabis. Attempts to create “cannabis clubs” or social lounges have been discussed around the state; however, at the time of writing there is no statewide legal framework that establishes open public consumption sites — local ordinances, zoning, and business licensing determine what’s possible and many cities remain cautious or restrictive. If you want to consume socially, find a private residence or a licensed environment (if/when permitted locally). (Cannabis Cactus)

Driving and impairment
Driving while impaired by cannabis is illegal. Arizona prosecutors may seek convictions by proving impairment (the standard can be “to the slightest degree”), and penalties can include jail, fines, and license sanctions. A higher court ruling in recent years has limited the ability to suspend licenses based solely on THC-positive tests without other evidence of impairment; still, impaired driving enforcement is a major priority for law enforcement. Never drive after consuming. (Salwin Law Group)

Expungements / record sealing Weed in Phoenix
Prop 207 included a path to petition courts to seal certain marijuana-related criminal records for acts committed before November 30, 2020. Eligible persons can file forms (often without fees) to request sealing/expungement — a meaningful change for people affected by prior laws. Maricopa County and Arizona courts have guidance and forms online. (Maricopa Justice Courts)

3) Buying cannabis in Phoenix — where and how Weed in Phoenix

Dispensaries & retail
Phoenix is home to numerous licensed dispensaries selling adult-use cannabis (flower, edibles, concentrates, topicals). Licensed retail stores must follow state rules on inventory tracking, purchase limits, taxation, and age verification. Most dispensaries accept walk-in customers and many offer online menus for ordering ahead; some offer curbside pickup. For the official list of licensed dispensaries, consult the Arizona Department of Health Services and local licensing pages. Weed in Phoenix

Payments & banking 
Because cannabis remains illegal federally, many cannabis businesses operate heavily in cash, though Arizona has seen increasing adoption of cashless/regulated payment systems designed for the cannabis industry. Expect a mix of cash and card-friendly options; always check the dispensary’s payment policy before visiting. Weed in Phoenix

Delivery
Home delivery for adult-use customers expanded after initial programs that focused on medical patients. As of recent regulatory updates, licensed dispensaries in Arizona were permitted to provide deliveries to adults 21+ through state-authorized channels — useful if you’d rather have products brought to your door. Always verify ID at delivery. (AP News)

Taxes
Cannabis sales are subject to state and local taxes; Arizona levies excise and transaction privilege (sales) taxes on adult-use products. Taxes can significantly raise the retail price over the pre-tax shelf price, so factor that into your budget.

What to expect at a dispensary
Bring a government-issued photo ID proving you are 21 or older. Staff (often called “budtenders”) can explain potency, dosage, and onset times, especially for edibles and concentrates. If you are a medical patient, bring your registry card or verify your status — medical product options and purchase/possession rules may differ. Weed in Phoenix

4) Growing cannabis in Phoenix — practical considerations Weed in Phoenix

Is home growing allowed?
Yes — with limits. Adults 21+ may cultivate up to six plants at a residence, or up to 12 plants in a residence with two or more qualifying adults. Plants must be in an enclosed, lockable area out of public view and secure from minors. Note that local ordinances and landlords/HOAs may impose stricter rules (landlords can ban cultivation in rental units). Read the exact statutory language before you grow. (Arizona Courts)

Indoor vs. outdoor grows
Because plants must not be visible to the public and must be secured from minors, many Phoenix residents choose indoor grows (closets, spare rooms, grow tents) with adequate ventilation, odor control, and safety measures. Outdoor grows can be legal only if they meet the visibility and security rules and local zoning allows it. Consider heat and humidity in Phoenix — indoor climate control is often necessary for consistent quality.

Electricity, odors, and neighbors
High-power lights and ventilation systems may increase power bills and draw attention. Strong odors can lead to complaints; use carbon filters, sealed tents, and proper airflow to mitigate smell. Check city and HOA rules regarding odor control and equipment.

Safety & legal limits
Exceeded plant counts or careless cultivation that allows access to minors can create criminal exposure. Keep clear documentation of adults living in the residence, and never sell unlicensed cannabis — retail sales require a licensed dispensary. If you plan to share or gift, be aware of the state’s transfer limits.

5) Consuming safely in Phoenix

Private property only
Public use (parks, sidewalks, restaurants, bars) is prohibited. Consume only on private property with the owner’s permission.

Know dosages, especially with edibles
Start low and go slow. Edibles can take 1–2 hours to feel full effect and can last much longer than inhaled cannabis. A typical beginner dose is 2.5–5 mg THC; many products have much higher doses per package. Ask budtenders for low-dose options and labeled products.

Don’t drive
Driving while impaired is illegal and dangerous. Use rideshare, taxis, or have a sober driver. If you’re stopped, be aware that law enforcement can pursue DUI charges if they believe you are impaired. Recent case law makes the technical interplay of THC tests and impairment more complex, but the practical rule is simple: if you are impaired, don’t drive. (Salwin Law Group)

Mixing substances
Avoid mixing alcohol and cannabis if impairment matters (e.g., driving). Combining substances can multiply impairment unpredictably.

6) Medical cannabis in Phoenix — how it differs

Arizona’s medical marijuana program predates Prop 207 and remains active. Qualifying patients with a registry card may possess and purchase larger “allowable amounts” under statute and have certain protections. Medical patients also historically had avenues (and sometimes different purchase limits) and priority registration at dispensaries. Consult Arizona Department of Health Services rules and the state statutes to understand exact quantities and patient rules. (Arizona Legislature)

7) Penalties, common legal pitfalls, and interactions with federal law

Where you can still be arrested
Possession above statutory limits, unlicensed sales, furnishing to minors, growing beyond legal limits, operating a grow that’s accessible to minors, or public consumption can still expose you to criminal charges. Major distribution or possession in large amounts still carries felony exposure under Arizona law; thresholds and penalties differ and are spelled out in state penal codes. (NORML)

Federal law still applies
Cannabis is illegal under federal law. That has consequences for banking, interstate transport (do not take cannabis across state lines, especially into states where cannabis is illegal), federal employment, and federally funded housing. In practice, most adults using cannabis within Arizona’s regulatory framework won’t face federal enforcement, but certain areas (federal lands, airports, interstate commerce) remain sensitive.

Employment & housing
Employers and landlords may still enforce drug-free policies, including testing and discipline for cannabis use. They may lawfully restrict cannabis use or cultivation in employment policies or rental agreements even if you comply with state law.

8) Expungement — fixing past records

Prop 207 created a pathway to petition courts to seal or expunge qualifying marijuana-related convictions or arrests that occurred before November 30, 2020. If you (or someone you’re helping) have an old cannabis conviction, look up the county court resources (Maricopa County provides guidance and forms) and consider consulting a lawyer or a legal aid clinic for assistance with filing. Sealing a record can remove large obstacles to housing, employment, and education. (Maricopa Justice Courts)
