Arizona Marijuana and Cannabis Laws After Proposition 207

Since Proposition 207 (2020) took effect in November 2020, adults 21 and over in Arizona may possess up to 1 ounce of marijuana and cultivate up to 6 plants. But large categories of marijuana conduct remain criminal: sales without a licensed dispensary, quantities above 1 ounce (2.5 oz+ becomes felony under A.R.S. 13-3405), DUI marijuana, and any possession by anyone under 21. Prop 207 also created retroactive expungement for prior marijuana convictions. Call (480) 582-3637 for a marijuana possession lawyer free consultation.

Arizona marijuana and cannabis laws under Prop 207


What Proposition 207 Actually Legalized

Proposition 207 passed in November 2020 with 60% voter support. It amended Arizona law to permit recreational adult marijuana use. Effective provisions for adults 21+:

  • Possession up to 1 ounce (28.35g) of marijuana in any form, including up to 5 grams of concentrate (hash, wax, oil).
  • Cultivation up to 6 plants per adult, capped at 12 plants per residence regardless of how many adults live there.
  • Purchase from licensed dispensaries regulated by Arizona Department of Health Services.
  • Transfer up to 1 ounce between adults 21+ without compensation (gifting).
  • Use on private property with owner permission. Public consumption remains prohibited.

Prop 207 also created a 16% excise tax on retail marijuana sales, funding public safety, community colleges, and infrastructure. Retail marijuana sales began January 2021 following expedited licensing of existing medical dispensaries.


Still Illegal: The Boundaries of Prop 207

Prop 207 did NOT legalize all marijuana conduct. The following remains criminal under A.R.S. 13-3405 and related statutes:

  1. Possession by anyone under 21. First offense with less than 1 oz is a petty offense with civil citation. Repeat offenses or larger amounts are criminal misdemeanors. Under-21 conduct is treated similarly to underage drinking.
  2. Possession above 1 ounce. 1 to 2.5 ounces is a petty offense (civil penalty, no criminal conviction). Above 2.5 ounces triggers Class 6 felony charges.
  3. Public consumption. Smoking or ingesting marijuana in public places (parks, streets, restaurants, workplaces) remains a criminal offense.
  4. Consumption in vehicles. Both driver and passenger consumption while the vehicle is in motion is illegal.
  5. Firearms and marijuana. Federal law prohibits firearm purchase or possession by anyone who uses marijuana, even legally under state law. State-legal use = federal disqualification.
  6. Employment and testing. Employers may still prohibit marijuana use and terminate for positive tests, though some 2023 amendments protect off-duty use in some contexts.

Sale of any amount without a state license — including “gifting” schemes that disguise sales — remains a serious felony. Class 3 or Class 4 depending on amount.


DUI Marijuana: The Enforcement Gap

Marijuana DUI is where Prop 207’s legalization runs into hard enforcement. Arizona’s DUI marijuana rule under A.R.S. 28-1381(A)(3) makes it a Class 1 misdemeanor to drive with any marijuana metabolite in the body. Metabolites can remain detectable for days to weeks after use — long after impairment ends.

Arizona courts have refined this rule in cases like State v. Shilgevorkyan (2014). The current standard requires proof that the metabolite indicates actual impairment, but enforcement varies significantly by county. Prosecutors in Maricopa and Pima counties still file marijuana DUI charges based on metabolite presence alone in many cases.

Penalties for marijuana DUI mirror standard DUI: 10-day mandatory jail (9 suspended), $1,250 base fine, mandatory alcohol/drug screening, 12-month ignition interlock, 90-day license suspension. The interlock requirement is particularly disruptive for regulated medical marijuana patients.

Defense strategies center on: proving no active impairment at the time of driving, disputing the metabolite testing methodology, and challenging the traffic stop under Fourth Amendment analysis. Prescription medical marijuana holders under A.R.S. 36-2812 have an additional defense pathway.


Sale, Cultivation, and Distribution Rules

Sale, distribution, and commercial cultivation remain regulated commercial activities. Retail sales require Arizona Department of Health Services dispensary licensing. Grow operations larger than 6 plants per adult (12 per residence) require commercial cultivation permits.

Unlicensed conduct penalties under A.R.S. 13-3405:

  • Sale under 2 pounds: Class 4 felony, presumptive 2.5 years prison. Probation-eligible for first offense.
  • Sale 2-4 pounds: Class 3 felony, presumptive 3.5 years prison.
  • Sale over 4 pounds: Class 2 felony, presumptive 5 years prison. Non-probationable at threshold (25 pounds).
  • Cultivation without permit, more than 6 plants: Class 5 felony.
  • Cultivation more than 4 pounds product: Class 3 felony.

The transition to legal recreational sales has created an enforcement priority shift. Small-scale unlicensed sales (below 2 pounds, first offense) frequently resolve through diversion or reduced charges. Large-scale unlicensed operations continue to face aggressive prosecution.

Related statutes: A.R.S. 13-3407 (dangerous drugs including synthetic cannabinoids), A.R.S. 13-3411 (drug-free school zones — enhances any drug offense within 300 feet of a school by one class), and A.R.S. 13-3415 (drug paraphernalia).


Prop 207 Expungement for Prior Convictions

One of Prop 207’s under-used features: retroactive expungement. Anyone with a prior Arizona conviction for conduct now legal under Prop 207 can petition to expunge it under A.R.S. 36-2801. Eligible convictions include:

  • Possession of up to 2.5 ounces of marijuana
  • Possession of paraphernalia used for personal-use marijuana
  • Cultivation of up to 6 plants (12 per residence with 2+ adults)

The petition process is administratively simple. There are no filing fees. The court must grant expungement if the conduct fits Prop 207 parameters and the petitioner is not currently serving a sentence for the same offense. Most petitions resolve within 60-90 days.

Expungement in Arizona under A.R.S. 36-2801 is stronger than set-aside. Expungement returns the conviction to a legal null state — for most purposes, the conviction is deemed never to have occurred. Employers, licensing boards, and background check services must remove the conviction from their records. Federal databases (NCIC, FBI) are also updated.

Approximately 250,000 Arizona marijuana convictions became eligible for expungement under Prop 207. Only a fraction have been petitioned so far. If you have a prior Arizona marijuana conviction and haven’t looked into expungement, this is a low-friction, high-value fix.


Employment, Housing, and Federal Impact

Legal marijuana use under state law does NOT protect against several external consequences:

  • Employment. Employers may still test for marijuana and terminate for positive results, though 2023 amendments to Arizona employment law added some off-duty use protections. Safety-sensitive positions (transportation, construction, healthcare with patient contact) remain fully subject to drug-free workplace requirements.
  • Federal employment. All federal employees, contractors, and members of the military remain fully subject to federal drug prohibitions regardless of state law. A positive marijuana test in federal employment is disqualifying.
  • Firearms. Federal ATF Form 4473 asks whether the buyer is “an unlawful user of marijuana.” Yes = federal felony to possess a firearm. Legal state use is still unlawful federally. This is a real prosecution risk.
  • Housing. Public housing and Section 8 recipients can be evicted for marijuana use even under state legalization. Private landlords may prohibit marijuana in leases.
  • Immigration. Marijuana conduct — even state-legal — can affect visa applications, green card renewals, and naturalization. USCIS treats marijuana as a controlled substance under federal law.
  • Professional licensing. Nurses, physicians, teachers, attorneys, and other licensed professionals may face licensing consequences for marijuana use in some circumstances.

The gap between state legalization and federal prohibition creates real risk. Legal marijuana use in Arizona can still trigger federal criminal exposure and professional consequences. Understand this before assuming Prop 207 fully protects the conduct.

1 ounce (28.35 grams) of marijuana flower, or up to 5 grams of concentrate (hash, wax, oil), for adults 21 and over under Prop 207. Amounts between 1 and 2.5 ounces are a petty offense with civil penalty only. Above 2.5 ounces triggers Class 6 felony charges under A.R.S. 13-3405. Under 21 possession of any amount remains criminal.

Yes, under A.R.S. 28-1381(A)(3), driving with any marijuana metabolite in the body is a Class 1 misdemeanor. Metabolites can remain detectable for days to weeks after use, long after impairment ends. Recent court decisions require proof of actual impairment for conviction, but enforcement varies significantly by county. Penalties mirror standard DUI: 10-day mandatory jail, $1,250 base fine, 12-month interlock.

Yes, if the conduct is now legal under Proposition 207. Under A.R.S. 36-2862, adults may petition to expunge convictions for possession of up to 2.5 ounces of marijuana, marijuana paraphernalia possession, and cultivation of up to 6 plants. Expungement is administratively simple, requires no fees, and the court must grant it if criteria are met. Roughly 250,000 Arizona convictions became eligible.

Yes. Employers may drug test for marijuana and terminate employees for positive results even for off-duty legal use. Some 2023 amendments added narrow off-duty protections, but safety-sensitive positions (transportation, construction, patient-facing healthcare) remain fully subject to drug-free workplace rules. Federal employees and contractors remain fully subject to federal marijuana prohibitions regardless of Arizona law.

Under Prop 207, adults 21+ may cultivate up to 6 plants for personal use, capped at 12 plants per residence regardless of how many adults live there. Plants must be grown in a locked space, out of public view. Cultivation above these limits is a Class 5 felony. Selling home-grown marijuana without a dispensary license is a Class 3 or 4 felony depending on quantity.
