What is ARS 13-3408 and how does it apply to fentanyl?

Being arrested for fentanyl in Maricopa County is frightening, and the fear is not misplaced. Arizona treats fentanyl as a narcotic drug, which means the charge lands in one of the most serious drug statutes on the books. But a charge is not a conviction, and the specific subsection you are charged under controls whether you face probation or prison and how much the case can be reduced. This guide, written by the defense team at Tamou Law Group, explains the law in plain English. For the broader picture, see our overview from Arizona drug crime lawyers.

A.R.S. § 13-3408 is Arizona’s narcotic drug statute, and fentanyl is prosecuted under it rather than the dangerous drug statute. The law makes it illegal to knowingly do any of seven things with a narcotic drug. Each act is a separate offense with its own felony class:

• Possess or use a narcotic drug (subsection A, paragraph 1): a class 4 felony.
• Possess for sale (paragraph 2): a class 2 felony.
• Possess equipment or chemicals to manufacture (paragraph 3): a class 3 felony.
• Manufacture a narcotic drug (paragraph 4): a class 2 felony.
• Administer it to another person (paragraph 5): a class 2 felony.
• Obtain it by fraud or deceit (paragraph 6): a class 3 felony.
• Transport for sale, import, sell, or transfer (paragraph 7): a class 2 felony.

The statute confirms fentanyl by name: recent subsections set special sentences for selling or transporting fentanyl in a motor vehicle. If you are accused of holding pills or powder for your own use, that is the class 4 possession charge. If the State alleges baggies, scales, cash, or text messages, prosecutors will try to charge the class 2 sale offense instead. Our pages on possession of narcotic drugs under A.R.S. 13-3408 and narcotic drug sales charges break down each side.

What are the penalties for fentanyl charges in Arizona?

Penalties for fentanyl charges in Arizona depend on the felony class and the amount involved. For a first-time offender with no prior felonies, A.R.S. § 13-702 sets the sentencing ranges for each class. When the amount of fentanyl reaches the statutory threshold, A.R.S. § 13-3408 removes the option of probation for sale and transport offenses, and a separate provision imposes long mandatory terms for large quantities.

What are the fentanyl threshold amounts in Arizona?

The fentanyl threshold amount in Arizona is nine grams. A.R.S. § 13-3401 defines the “threshold amount” for each drug, and it lists nine grams of fentanyl or fentanyl mimetic substances. This number matters enormously. Under A.R.S. § 13-3408, when the aggregate amount involved in a sale, administration, or transport offense equals or exceeds the threshold, the person convicted is not eligible for suspension of sentence, probation, or early release. In other words, crossing nine grams on a sale charge takes probation off the table.

A second, higher trigger was added by the Legislature in 2025. Selling 200 grams or more of fentanyl, or possessing that amount in a motor vehicle, carries the fixed 5, 10, and 15 year range described above. The State often weighs the entire mixture, not just the pure drug, so challenging how the substance was weighed and tested is frequently central to the defense. To understand how Arizona sorts and schedules controlled substances, see our guide on how Arizona classifies illegal drugs.

Can you get probation for a fentanyl charge?

Yes, in many personal-use cases you can. Arizona voters passed Proposition 200, now A.R.S. § 13-901.01, which requires the court to place a person convicted of the personal possession or use of a controlled substance on probation rather than sending them to prison. Fentanyl is a controlled substance, so a first-time or second-time simple possession charge under paragraph 1 generally qualifies for this mandatory probation.

There are important limits, and this is where fentanyl differs from methamphetamine. Prop 200 probation does not apply when any of the following is true under A.R.S. § 13-901.01:

• The charge is for possession for sale, production, manufacture, or transportation for sale, not personal use.
• The person has three or more prior convictions for personal possession.
• The person refused drug treatment or rejected probation.
• The person has been convicted of or indicted for a violent crime.
• The offense involved methamphetamine, which is specifically excluded.

Because the methamphetamine exclusion does not extend to fentanyl, a first-time personal possession of fentanyl is often still probation-eligible under Prop 200, a point that surprises many people who assume any fentanyl case means prison. Separately, A.R.S. § 13-3408 makes simple possession probation-eligible for someone with no prior felony record. Preserving that eligibility, by keeping a possession charge from being reclassified as a sale charge, is one of the most valuable things a defense lawyer does early.

What should you do in the first 72 hours after a fentanyl arrest?

The first three days shape the entire case. In Arizona courts, defense attorneys commonly see the same avoidable mistakes in the first 72 hours. At your initial appearance and later arraignment in Maricopa County, a commissioner sets release conditions and you enter a not-guilty plea; this is not the moment to explain your side. The most damaging errors people make are:

• Talking to detectives without a lawyer. “Cooperating” almost never reduces the charge, and statements about ownership or knowledge become the core of the State’s case.
• Consenting to searches of a phone, car, or home when officers ask, which can hand the prosecution the intent-to-sell evidence they were missing.
• Discussing the case on recorded jail calls, which prosecutors routinely obtain and play back.
• Posting about the arrest or contacting witnesses.

What prosecutors typically offer early is a plea to the charge as filed. A defense review often shows the search was questionable, the lab weight is contestable, or the sale allegation is thin, all of which change the leverage. Say little, ask for a lawyer, and let counsel do the talking. Our Phoenix drug crimes lawyer page explains what to expect locally.

How Tamou Law Group defends fentanyl charges

Tamou Law Group defends fentanyl charges by attacking the case at every weak point, from the stop to the lab. Because our team includes former prosecutors and law enforcement officers, we know how these cases are built and where they break. Common defense strategies include:

• Challenging the search and seizure. If officers lacked probable cause or a valid warrant, evidence can be suppressed, and a suppressed drug is often a dismissed case.
• Contesting knowing possession. The State must prove you knowingly possessed the fentanyl. Shared cars, borrowed bags, and multiple occupants create real doubt.
• Attacking the weight and lab analysis. Threshold and 200-gram allegations rise or fall on how the substance was weighed and tested. Contamination, mixtures, and chain-of-custody gaps matter.
• Fighting the sale-versus-possession label to preserve Prop 200 probation eligibility.
• Pursuing treatment-based resolutions and diversion where the facts support them.

No lawyer can promise an outcome, but we can promise a hard look at the evidence and a defense built for your specific facts. You can review our case results to see the kinds of matters we handle.
