Types of Illegal Substances in Arizona

Types of Illegal Substances in Arizona

Like most states, Arizona has gone to great lengths to organize the substances it considers illegal into a classification system. These systems serve several purposes. Not only do they allow lawmakers to address different sources of where these drugs come from, but more importantly, they help dictate the severity of the crimes associated with them. It is because of this that understanding what substance your drug charge involved is critical in forecasting what type of penalties you might face.

For so many drug cases, review, preparation, and strategy are just as essential as what happens inside the courtroom. If you are facing a drug charge and want thorough and studied representation, call us at the Davidson Criminal Defense & DUI Law Firm, PLC. As a former prosecutor, Attorney Davidson is well-versed in many ways drug charges and how best to address and counter these accusations.

Arizona’s drug classification system is closely modeled on the federal Controlled Substances Act (CSA) of 1970, which sorts drugs into schedules based on medical use, abuse potential, and safety profile. Arizona incorporated this framework into Title 13, Chapter 34 of the Arizona Revised Statutes (A.R.S. §13-3401 through §13-3461), which lists the specific substances that fall into each of the state’s six drug classes and sets out the penalties tied to each one.

Classes of Illegal Substances

There are six major categories for controlled substances in Arizona. They address the substance origin, level of danger it poses to the human body, and the prevalence of addictive use.
The major drug classifications in Arizona include:

• Narcotic drugs (heroin, cocaine, etc.)
• Dangerous drugs (mescaline, methamphetamine, etc.)
• Prescription drugs
• Marijuana
• Toxic vapor substances (chloroform, nitrous oxide, etc.)
• Peyote

Narcotic Drugs — A.R.S. §13-3408

Narcotic drugs are defined under A.R.S. §13-3401 and include substances such as heroin, cocaine, opium, and morphine. Penalties for narcotic offenses are set out in A.R.S. §13-3408, and a first-time narcotic possession charge is typically prosecuted as a class 4 felony, though it may sometimes be reduced through diversion or plea negotiation.

Dangerous Drugs — A.R.S. §13-3407

“Dangerous drugs” is a broad category defined in A.R.S. §13-3401 and covers methamphetamine, MDMA (ecstasy), LSD, PCP, and anabolic steroids, among others. Possession of a dangerous drug is charged under A.R.S. §13-3407 and is generally a class 4 felony, carrying a presumptive prison term even for a first offense in some circumstances — which is why early representation matters.

Prescription Drugs — A.R.S. §13-3406

Prescription drug charges cover controlled medications such as Xanax, Oxycodone, and Vicodin when they are possessed, sold, or obtained without a valid prescription. While A.R.S. §13-3406 penalties are generally less severe than for narcotic or dangerous drug offenses, prescription drug cases often carry an added layer of complexity — charges like prescription fraud and doctor shopping frequently accompany a possession charge.

Marijuana

Marijuana is regulated separately under A.R.S. §13-3405 and by Arizona’s 2020 legalization measure (Proposition 207), which allows limited legal possession for adults 21 and older. Charges still arise for possession above the legal limit, sale, cultivation, or possession by someone under 21 — each carrying its own felony classification depending on quantity.

Toxic Vapor Substances — A.R.S. §13-3403

This class covers inhalants like chloroform, nitrous oxide, and other vapor-releasing substances. Arizona law restricts the sale of these substances, particularly to minors, and can charge related conduct as a misdemeanor or felony depending on the circumstances and intent involved.

Peyote

Peyote is separately classified under Arizona law and carries a narrow legal exception for use in bona fide religious ceremonies by members of the Native American Church. Outside that exception, possession, sale, or transport of peyote is prosecuted like other controlled substances.

For example, heroin and cocaine would be considered a narcotic, while methamphetamines would fall under dangerous drugs. Depending on which type of drug you are found with, you may be facing severe consequences. It should also be noted that Arizona has also flagged a number of substances that are commonly used in the production of drugs and can charge individuals for possessing certain amounts of materials or substances.

To find out how your drug charge is classified and what penalties it could yield in a court of law, retain knowledgeable representation as soon as possible. At the Davidson Criminal Defense & DUI Law Firm, PLC, we know how important it is for the accused and their families to understand their charges and how critical proper defense can be in avoiding maximum penalties.

Precursor Chemicals & Manufacturing Materials

Beyond the six drug classes, Arizona law separately criminalizes the possession of precursor chemicals and equipment used to manufacture controlled substances, most often methamphetamine. These charges are typically prosecuted as felonies even when no finished drug is found, because the law targets the manufacturing process itself. If you’re facing a manufacturing or precursor-related charge, our drug manufacturing page explains how these cases are built and defended.

FAQs

What is the difference between a narcotic and a dangerous drug in Arizona?

Narcotic drugs (like heroin and cocaine) and dangerous drugs (like methamphetamine and ecstasy) are both felony-level classifications, but they’re charged under different statutes — A.R.S. §13-3408 for narcotics and A.R.S. §13-3407 for dangerous drugs — with different sentencing ranges.

Is marijuana still illegal in Arizona?

Adults 21 and older may legally possess limited amounts of marijuana under Proposition 207, but possession above the legal threshold, sale without a license, or possession by someone under 21 can still result in criminal charges.

Can I be charged for drug paraphernalia or precursor chemicals alone?

Yes. Arizona law allows charges for possessing equipment or precursor chemicals used to manufacture drugs, separate from any charge involving a finished, classified substance.
