Cannabis Concentrate Regulations in Arizona

Legal status overview

Cannabis concentrates — including hash, kief, wax, shatter, rosin, live resin, distillate, and vape cartridges — are legal in Arizona for two groups: registered medical patients under the Arizona Medical Marijuana Act (AMMA, 2010) ^[1] and adults 21+ under the Smart and Safe Arizona Act (Proposition 207, effective Nov 30, 2020) ^[2][3].

Both programs require concentrates to be produced and sold only by licensed dispensaries (now called 'marijuana establishments' under Prop 207). Concentrates purchased outside the licensed system — including from out-of-state dispensaries, even those in legal states — remain illegal to possess or transport into Arizona Strong evidence.

Possession limits for adults 21+

Under A.R.S. § 36-2852, an adult 21 or older may possess up to one ounce (28.35 g) of marijuana, of which no more than five grams may be in the form of marijuana concentrate ^[3].

The statute defines 'marijuana concentrate' as the resin extracted from any part of the cannabis plant and every compound, manufacture, salt, derivative, mixture, or preparation of that resin ^[3]. That definition is broad enough to cover hash, rosin, BHO, CO2 oil, distillate, and the cannabis oil inside vape cartridges.

Possession of more than one ounce but not more than 2.5 ounces (with the same 5 g concentrate sub-cap) is a petty offense (civil-style penalty) rather than a criminal charge under § 36-2853. Above 2.5 ounces, criminal penalties under Title 13 reappear ^[3] Strong evidence.

Possession limits for medical patients

Registered qualifying patients may possess up to 2.5 ounces of usable marijuana in any 14-day period under A.R.S. § 36-2801 ^[1]. Arizona's Supreme Court resolved a long-running ambiguity in State v. Jones (2019), holding that 'marijuana' under the AMMA includes resin and concentrates, so patients are protected when possessing extracts within the 2.5-ounce limit ^[4][5].

Before Jones, prosecutors in some counties had charged patients with felony narcotics possession for hash and vape cartridges. That practice is no longer lawful, but the 2.5-ounce cap still applies and there is no separate concentrate sub-limit for medical patients the way there is for adult-use consumers Strong evidence.

Home extraction and manufacturing

Both Prop 207 and the AMMA explicitly prohibit home production of concentrates using volatile solvents such as butane, propane, hexane, or ether. A.R.S. § 36-2853(B) makes it a class 6 felony for a person to 'possess, transport, or process marijuana using a substance other than water or lawful nonvolatile solvent if the resulting product is intended for human consumption' outside of a licensed facility ^[3].

Non-solvent methods — dry sift, ice water hash, and mechanical rosin pressing — are not addressed by the volatile-solvent prohibition, but the finished product still counts toward your possession limits. Selling or gifting beyond statutory limits is separately illegal Strong evidence.

Licensed production and testing

ADHS regulates licensed manufacturers under the Arizona Administrative Code, Title 9, Chapter 17 (medical) and Chapter 18 (adult-use) ^[6][7]. Key rules for concentrates:

• Extraction facilities must be approved by ADHS and meet local fire/building codes.
• All concentrates sold at retail must be tested by an ADHS-certified independent laboratory for potency and contaminants (residual solvents, pesticides, heavy metals, microbials, mycotoxins) before sale ^[7].
• Labels must disclose THC and CBD content, batch number, manufacture date, and standard warnings.
• Edibles infused with concentrate are capped at 10 mg THC per serving and 100 mg per package under R9-18-form rules ^[7].

Vape cartridges are treated as concentrates for possession purposes; the oil weight (not the hardware weight) counts toward the 5-gram cap [evidence:weak — ADHS guidance is limited; some prosecutors have used gross weight historically].

Public consumption, vehicles, and workplaces

Smoking or vaporizing cannabis — including concentrate vapes — in any public place or open space remains illegal under A.R.S. § 36-2851 ^[3]. Driving under the influence of cannabis remains a DUI offense under A.R.S. § 28-1381; Arizona is not a per-se THC state for medical patients after Dobson v. McClennen (2015), but impairment-based DUI still applies Strong evidence.

Employers may still enforce drug-free workplace policies and test for cannabis metabolites under A.R.S. § 23-493 et seq. Prop 207 did not create employment protections for cannabis users, including concentrate users ^[3] Strong evidence.

Federal overlay

All cannabis concentrates above 0.3% delta-9 THC by dry weight remain Schedule I under the federal Controlled Substances Act, regardless of Arizona law ^[8]. This affects banking, firearms purchases (ATF Form 4473 question 21g), federal employment, federal housing, and travel through federal facilities and airports. The TSA's stated policy is to refer suspected cannabis to local law enforcement; at Sky Harbor and Tucson International, local enforcement reflects Arizona law for amounts within state limits, but federal property exposure remains [evidence:weak — based on agency policy statements, not statute].

Recent and pending changes

• 2020: Proposition 207 passed, legalizing adult-use cannabis and concentrates with the 1 oz / 5 g concentrate caps.
• 2019: State v. Jones confirmed AMMA covers resin/concentrates ^[4].
• 2021: First adult-use concentrate sales began Jan 22, 2021 after ADHS issued early licenses ^[2].
• Ongoing: ADHS periodically updates testing and labeling rules in 9 A.A.C. 18. Always check the current Arizona Administrative Code before relying on specific limits.
