Arizona classifies drugs into six categories under A.R.S. 13-3401: narcotic drugs, dangerous drugs, marijuana, peyote, prescription-only drugs, and vapor-releasing substances. Simple possession of narcotic or dangerous drugs is a Class 4 felony under A.R.S. 13-3407. Marijuana possession by adults 21+ is legal up to one ounce under Proposition 207 (2020). Threshold amounts and prior convictions escalate charges up to Class 2 felony with 10.5-year presumptive prison. Call (480) 582-3637 for a drug possession lawyer free consultation.

The Six Drug Categories Under A.R.S. 13-3401
Arizona doesn’t use the federal Schedule I-V classification for state charges. Instead, A.R.S. 13-3401 groups controlled substances into six state categories with different penalty structures:
- Narcotic drugs — heroin, cocaine, fentanyl, opioid pain medications outside legitimate prescription. Governed by A.R.S. 13-3408.
- Dangerous drugs — methamphetamine, ecstasy (MDMA), LSD, psilocybin, ketamine, GHB. Governed by A.R.S. 13-3407.
- Marijuana — cannabis and its derivatives. Governed by A.R.S. 13-3405. Adult recreational use legalized by Proposition 207 (2020) in 2020.
- Peyote — A.R.S. 13-3402. Religious use exemption for members of the Native American Church.
- Prescription-only drugs — controlled prescriptions possessed outside a valid prescription. A.R.S. 13-3406.
- Vapor-releasing substances — inhalants used for intoxication. A.R.S. 13-3402.
Each category has its own possession, use, sale, and manufacturing statute. The category directly determines the felony class. Federal charges are separate — a substance that is a federal Schedule II (like cocaine) is a state “narcotic drug.” A substance that is federal Schedule I (like heroin) may fall under a different Arizona category. Multi-jurisdictional cases require careful analysis of both frameworks.
Narcotic Drugs: A.R.S. 13-3408
Narcotic drug offenses are the most severely punished non-manufacturing drug crimes in Arizona. A.R.S. 13-3408 defines seven distinct offenses:
| Conduct | Classification | Presumptive Term |
|---|---|---|
| Simple possession or use | Class 4 felony | 2.5 years prison, probation-eligible under A.R.S. 13-901.01 |
| Possession for sale (below threshold) | Class 2 felony | 5 years prison |
| Possession for sale (threshold amount+) | Class 2 felony, non-probationable | 10.5 years mandatory prison |
| Transportation for sale | Class 2 felony | 5 years or 10.5 years (threshold) |
| Manufacture | Class 2 felony, non-probationable | 10.5 years mandatory prison |
Cocaine and heroin threshold amount: 9 grams. Fentanyl threshold: 9 grams (or 200 dosage units). At or above threshold, the sentence becomes mandatory prison — probation is unavailable. This is the point at which drug cases become life-altering.
A.R.S. 13-901 (Proposition 200) mandates probation and drug treatment (not prison) for FIRST or SECOND simple possession or personal use convictions — but this protection ends at the third offense OR any sale/manufacture conviction. It is one of the strongest defense levers available for first-time defendants.
Dangerous Drugs: A.R.S. 13-3407
Dangerous drugs are punished nearly as severely as narcotic drugs. A.R.S. 13-3407 covers methamphetamine, MDMA (ecstasy), LSD, psilocybin, ketamine, GHB, and PCP among others.
- Simple possession or use: Class 4 felony, presumptive 2.5 years prison. Prop 200 probation eligibility applies to first/second offenses.
- Possession for sale below threshold: Class 2 felony.
- Possession for sale threshold amount+: Class 2 felony, mandatory prison.
- Manufacturing: Class 2 felony, mandatory prison. Methamphetamine manufacturing includes additional enhancement for children in the residence.
Threshold amounts for common dangerous drugs:
- Methamphetamine: 9 grams
- MDMA (ecstasy): 750 milligrams or 4 dosage units
- LSD: 500 dosage units
- Ketamine: 4 grams
The threshold trigger is critical. A defendant with 8.9 grams of meth faces probation-eligible Class 4 felony possession. At 9.0 grams, the same defendant faces mandatory prison under Class 2 possession for sale. Prosecutors often push the “for sale” enhancement based on packaging, cash, scales, or communications — even when the amount is below threshold. Fighting the “for sale” element is often the difference between probation and years in prison.
Marijuana After Proposition 207
Arizona’s marijuana law changed dramatically with Proposition 207 (2020), effective November 2020. Adults 21 and over may:
- Possess up to 1 ounce of marijuana (with no more than 5 grams as concentrates)
- Cultivate up to 6 plants per person, or 12 per residence with 2+ adults
- Purchase from licensed dispensaries under the Arizona Department of Health Services regulatory framework
Marijuana is NOT legal at the federal level, and it remains restricted for anyone under 21. Arizona penalties for prohibited marijuana conduct:
- Under 21 or over 1 oz (non-medical, adult): Petty offense (up to 1 oz, first offense); Class 6 felony (over 1 oz).
- Sale without dispensary license: Class 3 or Class 4 felony under A.R.S. 13-3405, depending on amount.
- Manufacture of hash oil or concentrate above 5 grams: Still a serious felony even for legal adults.
- DUI marijuana: Separate offense under A.R.S. 28-1381(A)(3). Metabolites can trigger charges for weeks after consumption.
Prop 207 also created an expungement pathway. Anyone with a prior conviction for conduct now legal under Prop 207 can petition for expungement under A.R.S. 36-2801. Roughly 250,000 Arizona convictions became eligible for expungement in 2021. This is one of the most under-used remedies in Arizona criminal law.
Threshold Amounts and Enhanced Penalties
Threshold amounts are the pivotal number in Arizona drug law. At threshold or above, the defendant faces mandatory prison and loses Prop 200 probation eligibility. The thresholds by substance:
| Substance | Threshold | Statute Reference |
|---|---|---|
| Cocaine | 9 grams | A.R.S. 13-3401(36)(b) |
| Heroin | 9 grams | A.R.S. 13-3401(36)(g) |
| Methamphetamine | 9 grams | A.R.S. 13-3401(36)(k) |
| Fentanyl | 9 grams OR 200 dosage units | A.R.S. 13-3401(36)(f) |
| MDMA (ecstasy) | 750 mg OR 4 dosage units | A.R.S. 13-3401(36)(l) |
| LSD | 500 dosage units | A.R.S. 13-3401(36)(i) |
| Ketamine | 4 grams | A.R.S. 13-3401(36)(h) |
A.R.S. 13-604 adds repetitive-offender enhancements. Two or more prior felony convictions triggers mandatory prison, disqualifies probation, and expands sentencing ranges. A third drug felony with prior history routinely triggers 10+ year prison sentences even for possession without sale.
Fentanyl is the newest and most severely punished drug. Recent legislative changes made fentanyl trafficking of any amount a Class 2 felony with enhanced minimums. This is a rapidly-evolving area — statutes changed in 2022, 2023, and again in 2024.
Defenses and Sentence Reduction Options
Effective defenses against Arizona drug charges:
- Illegal search or seizure. Most drug cases turn on Fourth Amendment analysis. Fourth Amendment governs. If the officer lacked probable cause for the stop, search, or vehicle entry, the drugs are suppressed and the case dismisses. See Search and seizure doctrine for the underlying doctrine.
- Constructive possession challenges. Drugs found in a vehicle or house shared by multiple people may not be legally attributable to the defendant. The state must prove knowledge AND control.
- Lab and chain-of-custody attacks. DPS crime lab errors, delayed testing, and chain gaps sometimes exclude the drug identification itself.
- Prop 200 (A.R.S. 13-901.01) probation. For first-time or second-time simple possession, MANDATORY probation and treatment instead of prison. The prosecution cannot avoid this by charge structuring.
- Diversion programs. County-level diversion (drug court, TASC) results in dismissal upon completion for eligible defendants.
- Prop 207 retroactive expungement. Prior marijuana convictions now legal are expungement-eligible under A.R.S. 36-2801.
The State Bar of Arizona tracks resolutions: roughly 40-50% of first-time drug possession cases end in dismissal, diversion, or Prop 200 probation when represented by counsel. Pro-se defendants face conviction rates above 90%. The gap is largely the Fourth Amendment analysis, which is legally complex.

Frequently Asked Questions
Under A.R.S. 13-3401(6), a dangerous drug includes methamphetamine, MDMA (ecstasy), LSD, psilocybin, ketamine, GHB, PCP, and various synthetic hallucinogens. Simple possession of a dangerous drug is a Class 4 felony under A.R.S. 13-3407, presumptive 2.5-year prison but probation-eligible under Prop 200 for first and second offenses. The category is distinct from narcotic drugs (heroin, cocaine, fentanyl), which are governed by A.R.S. 13-3408.
Threshold amounts vary by drug: 9 grams for cocaine, heroin, methamphetamine, and fentanyl (or 200 dosage units for fentanyl); 750 mg or 4 dosage units for MDMA; 500 dosage units for LSD; 4 grams for ketamine. At or above threshold, possession-for-sale becomes non-probationable Class 2 felony with mandatory 10.5-year presumptive prison. Below threshold, sale offenses remain probation-eligible.
Adults 21 and older can possess up to 1 ounce of marijuana or 5 grams of concentrate under Proposition 207 (2020). Cultivation is limited to 6 plants per adult (12 per residence with 2+ adults). Possession above 1 ounce but under 2.5 ounces is a petty offense on first violation; above 2.5 ounces becomes a Class 6 felony under A.R.S. 13-3405. Sale without a licensed dispensary permit remains a Class 3 or 4 felony regardless of amount.
Yes, in many cases. The most common dismissal grounds are: illegal search and seizure violating the Fourth Amendment, constructive possession challenges when drugs are found in shared spaces, Miranda violations for custodial statements, and chain of custody errors at the lab. Additionally, first and second-time simple possession offenders qualify for mandatory probation and treatment under Prop 200 (A.R.S. 13-901.01), not conviction and prison.
Proposition 200 (codified at A.R.S. 13-901.01) requires the court to impose probation and drug treatment (not prison) for first-time and second-time personal-use drug possession convictions. The rule applies regardless of the drug type and cannot be avoided through charge structuring. Prop 200 does NOT apply to third offenses, sale/distribution charges, or manufacturing charges — those retain full felony consequences.
Yes, if the underlying conduct is now legal under Proposition 207. Adults may petition to expunge convictions for possession of up to 2.5 ounces of marijuana, possession of paraphernalia, and cultivation of up to 6 plants under A.R.S. 36-2862. Roughly 250,000 Arizona convictions became eligible for expungement when Prop 207 passed in 2020. The petition process requires no fees and typically resolves within 60-90 days.
Drug possession threshold amounts determine whether you face probation or mandatory prison. Prop 200 protects first-time offenders. Derek Oliverson defends Arizona drug cases since 2009.
