Arizona Drug Laws: Possession, Thresholds, and Sentencing

Arizona drug laws treat most controlled substance offenses as felonies, but the real penalty depends on three things: what the drug is, how much of it you had, and whether anything suggests you planned to sell it. Simple possession for personal use is typically a Class 4 felony with a presumptive 2.5-year prison term, yet first-time offenders usually qualify for mandatory probation and drug treatment instead of prison under Proposition 200. Cross the statutory “threshold amount,” though, and prison becomes mandatory with no probation option, regardless of whether the drugs were for personal use.

How Arizona Groups Controlled Substances

The category a drug falls into decides which statute applies and how harsh the penalties get.

Narcotic drugs include heroin, cocaine, fentanyl, oxycodone, and other opioids. These carry the steepest mandatory fines.
Dangerous drugs is a broad group covering methamphetamine, amphetamine, LSD, MDMA, PCP, psilocybin, GHB, and dozens of synthetic compounds including synthetic cannabinoids.¹
Prescription-only drugs are medications that require a prescription, possessed without one. Benzodiazepines and certain sleep aids are common examples.

The distinctions can be counterintuitive. Methamphetamine is classified as a dangerous drug rather than a narcotic, yet it triggers some of the harshest enhanced sentencing in the entire drug code. Cocaine, by contrast, is a narcotic and sits under a separate statute with its own mandatory fines. Marijuana is treated under its own framework since recreational legalization in 2020.

Penalties for Personal Possession

Possessing a controlled substance for personal use with no evidence of intent to sell falls under one of three statutes depending on the substance.

Narcotic Drugs

Possessing any amount of a narcotic drug for personal use is a Class 4 felony with a presumptive 2.5-year prison term.² On top of any sentence, the court must impose a fine of at least $2,000 or three times the street value of the drugs, whichever is greater. Judges cannot waive or reduce this fine.

Dangerous Drugs

Possessing a dangerous drug for personal use is also a Class 4 felony with the same 2.5-year presumptive term.³ There’s one meaningful carve-out. If the drug isn’t methamphetamine, LSD, amphetamine, or PCP, and the person has no prior felony convictions, the prosecutor can ask the court to reduce the offense to a Class 1 misdemeanor, or to place the person on probation without designating the conviction as either a felony or misdemeanor until probation is completed. The mandatory fine is at least $1,000 or three times the value of the drugs.

Prescription-Only Drugs

Simple possession or use of a prescription drug without a valid prescription is a Class 1 misdemeanor, carrying up to six months in jail.⁴ If prosecutors show intent to sell, the charge becomes a Class 6 felony.

Proposition 200: Probation and Treatment Instead of Prison

Arizona voters passed Proposition 200 to divert personal-use drug offenders away from prison, and it still shapes outcomes for most first-time cases. Under A.R.S. 13-901.01, anyone convicted of personal possession or use of a controlled substance, or of drug paraphernalia, is eligible for probation. The statute doesn’t say the court “may” grant probation. It says the court “shall” suspend the sentence and place the person on probation.⁵

As a condition, the person must participate in a drug treatment or education program and pay for it to the extent they can afford. A second personal-use conviction still qualifies for probation, though the court can impose tougher conditions such as intensive supervision, home arrest, or community service.

Two limits matter. Proposition 200 applies only to personal possession and use. Anyone convicted of selling, manufacturing, or transporting drugs doesn’t qualify. And if the amount possessed exceeds the statutory threshold, probation is unavailable entirely.

Threshold Amounts That Trigger Mandatory Prison

Arizona draws a firm line at specific drug quantities called threshold amounts. Possess more than the threshold and you face mandatory prison, no probation, no suspended sentence, even if the drugs were for personal use. The thresholds are:¹

Heroin: 1 gram
Cocaine: 9 grams
Methamphetamine: 9 grams
Amphetamine: 9 grams
Fentanyl: 9 grams
PCP: 4 grams or 50 milliliters
LSD: half a milliliter, or 50 blotter doses
Marijuana: 2 pounds
Any other unlawful substance: a street value of at least $1,000

The heroin threshold is particularly low. One gram is enough to cross it, and someone with a daily habit could easily possess that amount. Once the threshold is crossed, Proposition 200 no longer applies, and the sentencing framework shifts to one built for trafficking-level offenses.

Sale, Manufacturing, and Transportation

Charges involving sale, production, or transportation for distribution carry the heaviest penalties in the drug code. Prosecutors frequently infer intent to sell from circumstantial evidence: large quantities of cash, packaging materials, scales, multiple phones, or text messages about transactions.

Selling a dangerous drug, possessing one for sale, or transporting one for sale is a Class 2 felony. Manufacturing is generally a Class 3 felony, but manufacturing methamphetamine is a Class 2 felony.³ A first-time Class 2 felony conviction carries a presumptive 5-year prison term, with the range running from 3 years (mitigated) to 12.5 years (aggravated).⁶

Methamphetamine has its own enhanced structure. Anyone convicted of selling, transporting, or manufacturing meth faces a minimum of 5 calendar years, a presumptive term of 10 years, and a maximum of 15 years. A second such meth offense raises the range to 10 to 20 years.

The narcotic drug framework mirrors the dangerous drug statute: sale, possession for sale, and transportation for sale are Class 2 felonies, and manufacturing is a Class 3 felony.² The mandatory minimum fine is $2,000 rather than $1,000. Fentanyl trafficking at 200 grams or more triggers a 5-year minimum, 10-year presumptive, and 15-year maximum, with a second offense pushing the range to 10 to 20 years.

For prescription drugs, selling or transporting without authorization is a Class 6 felony, and manufacturing a misbranded drug is a Class 4 felony.⁴

Marijuana After Proposition 207

Arizona legalized recreational marijuana for adults 21 and older in 2020. Adults may possess up to one ounce, with no more than five grams in the form of concentrate. Growing up to six plants at your primary residence is legal, with a household cap of 12 plants if two or more adults live there, and plants must be in an enclosed, locked area out of public view.⁷

Violating these limits carries graduated penalties. Possessing more than one ounce but no more than 2.5 ounces (with up to 12.5 grams of concentrate) is a petty offense punishable by a fine. Cultivation visible from public view, or outside a locked enclosure, is a petty offense for a first violation and a Class 3 misdemeanor for a second. Underage possession of one ounce or less brings a $100 civil penalty for a first violation, a petty offense for a second, and a Class 1 misdemeanor for a third.

When Marijuana Is Still a Felony

Proposition 207 did not eliminate marijuana felonies. Possession above 2.5 ounces falls under A.R.S. 13-3405, which sets penalties by weight:⁸

Under 2 pounds, not for sale: Class 6 felony
2 to 4 pounds, not for sale: Class 5 felony
4 pounds or more, not for sale: Class 4 felony
Under 2 pounds for sale: Class 4 felony
2 to 4 pounds for sale: Class 3 felony
Over 4 pounds for sale: Class 2 felony

Two pounds is also the threshold amount for marijuana, so anyone at or above that weight faces mandatory prison with no probation eligibility.

Federal Law Still Conflicts

As of late 2025, marijuana remains a Schedule I substance under the federal Controlled Substances Act. A proposed rule to reschedule marijuana to Schedule III has been issued but is still awaiting an administrative hearing.⁹ Federal prosecution for personal marijuana use that complies with Arizona law is rare, but the conflict matters for federal employees, people with security clearances, and anyone transporting marijuana across state lines.

Drug Paraphernalia

Possessing items intended for use with controlled substances is a separate offense under A.R.S. 13-3415, covering any equipment or materials used to grow, manufacture, test, package, or consume an illegal drug. The charge turns on intent. The item itself doesn’t have to be illegal, and no drugs need to be present at arrest.¹⁰

Paraphernalia possession is a Class 6 felony with a presumptive one-year term. Because it’s a personal-use offense, first- and second-time offenders qualify for mandatory probation and treatment under Proposition 200 rather than prison.⁵ Paraphernalia related to marijuana use by adults 21 and older is exempt from prosecution under Proposition 207.

Drug-Impaired Driving

Arizona has one of the strictest drug DUI laws in the country. Under A.R.S. 28-1381, it’s illegal to drive or be in actual physical control of a vehicle while impaired to the slightest degree by any drug, or while any drug defined in A.R.S. 13-3401, or even its metabolite, is in your body.¹¹

The metabolite clause is the trap. Certain drug metabolites remain in the body for days or weeks after use, long after any impairment has passed. You can test positive and face a DUI even if you weren’t actually impaired at the time of driving. A valid prescription from a licensed medical practitioner is a defense to the metabolite charge, but not to a separate charge of driving while actually impaired. A first-offense drug DUI is a Class 1 misdemeanor carrying up to six months in jail, fines, and license suspension.

Sealing a Drug Conviction

Arizona allows people with drug convictions to petition the court to seal their criminal records under A.R.S. 13-911. You must have completed all terms of your sentence, including fines, restitution, and probation, and then wait a set period before filing:¹²

Class 2 or 3 felony: 10 years
Class 4, 5, or 6 felony: 5 years
Class 1 misdemeanor: 3 years
Class 2 or 3 misdemeanor: 2 years

If you have a prior historical felony conviction, add five years. The petition goes to the court where you were convicted. Records can’t be sealed if you were sentenced as a dangerous offender or convicted of certain violent or sexual offenses, but standard drug convictions generally qualify. Charges that were dismissed or ended in acquittal can be sealed without a waiting period.

Proposition 207 also created a separate expungement process specifically for marijuana convictions that would no longer be illegal under current law. It operates independently of the general record-sealing statute.

Collateral Consequences

The penalties written into the statutes are only part of what a drug conviction costs.

Public housing is a major pressure point. Federal law imposes a mandatory three-year ban on readmission for tenants evicted for drug-related activity, and local housing authorities have discretion to extend that ban or deny applications from anyone with a drug record. Many authorities adopt policies stricter than the federal floor and screen applicants through national criminal history databases.

Federal student aid eligibility is no longer affected by drug convictions. That restriction was eliminated in recent years.¹³ Individual colleges and scholarship programs may still consider drug convictions in their own decisions.

Employment effects are harder to predict but consistently significant. A felony drug conviction can disqualify you from professional licenses in healthcare, education, law, and financial services. Arizona allows people to petition for restoration of civil rights after completing a sentence, but that process doesn’t erase the conviction from your record. Only sealing accomplishes that.
