12.4 Controlled Substances (ARS Title 13 Ch 34), Criminal Street Gangs (ARS 13-2321) & Specific Property Crimes

Key Takeaways

  • Under A.R.S. Title 13, Chapter 34, controlled substances are categorized into distinct statutory classes: Marijuana (A.R.S. § 13-3405, subject to Proposition 207 personal limits), Prescription-only drugs (A.R.S. § 13-3406), Dangerous drugs (A.R.S. § 13-3407, e.g., methamphetamine, hallucinogens), and Narcotic drugs (A.R.S. § 13-3408, e.g., fentanyl, heroin, cocaine).
  • A.R.S. § 13-3401(36) establishes strict statutory threshold amounts (1 gram of heroin, 9 grams of cocaine including hydrolyzed cocaine, 9 grams of methamphetamine, 9 grams of amphetamine, 9 grams of fentanyl or fentanyl mimetic substances, 4 grams or 50 milliliters of PCP, one-half milliliter or 50 blotter dosage units of LSD, and 2 pounds of marijuana) that legally mandate a prison sentence upon conviction, eliminating probation eligibility.
  • Under A.R.S. § 13-105(9), validating an individual as a Criminal Street Gang Member requires satisfying at least two of seven enumerated statutory criteria, including self-proclamation, tattoos, clothing/colors, or paraphernalia.
  • Unlawful Use of Means of Transportation (A.R.S. § 13-1803, Class 6 felony joyriding) involves taking unauthorized control of a vehicle without intent to permanently deprive, whereas Theft of Means of Transportation (A.R.S. § 13-1814, Class 3 felony) requires intent to permanently deprive the owner.
  • Illicit synthetic fentanyl poses severe respiratory depression hazards; officers must maintain protective handling standards (gloves, respiratory masks, avoiding aerosolization) and be equipped with naloxone (Narcan) for emergency opioid reversal.

12.4 Controlled Substances (ARS Title 13 Ch 34), Criminal Street Gangs (ARS 13-2321) & Specific Property Crimes

AZPOST Comprehensive Examination Focus: Peace officer candidates must master the statutory framework of Arizona Revised Statutes (A.R.S.) Title 13, Chapter 34 (Drug Offenses), distinguish dangerous drugs from narcotic drugs, identify mandatory prison threshold amounts under A.R.S. § 13-3401(36), implement fentanyl safety and naloxone protocols, apply criminal street gang validation criteria under A.R.S. §§ 13-105(8)–(9) and 13-2321, and contrast specific property crimes including joyriding vs. grand theft auto (A.R.S. §§ 13-1803 and 13-1814), chop shops, and identity theft pursuant to Ariz. Admin. Code R13-4-116(E)(1)(e)(viii)–(x).

Major felony investigations frequently intersect at the junction of illicit narcotics, organized criminal street gangs, and specialized property crimes. A thorough command of Arizona's penal statutes allows peace officers to accurately categorize controlled substances, validate street gang involvement for enhanced statutory penalties, identify altered vehicle identifiers, and properly charge property theft offenses.


1. Arizona Controlled Substances Framework (A.R.S. Title 13, Ch. 34)

Arizona divides controlled substances into distinct statutory classifications under A.R.S. Title 13, Chapter 34. Officers must know which specific substances belong to each statutory category because classifications dictate charging levels and sentencing enhancements.

                             [ Arizona Controlled Substances Spectrum ]

1. Marijuana (A.R.S. § 13-3405 & Proposition 207)

Under the Smart and Safe Arizona Act (Proposition 207 / A.R.S. Title 36, Chapter 28.2), adult possession of marijuana was legalized subject to strict statutory boundaries:

  • Lawful Adult Possession (Age 21+): Adults aged 21 or older may lawfully possess up to 1 ounce (28 grams) of marijuana, of which not more than 5 grams may be in the form of marijuana concentrate.
  • Petty Offense Tier (A.R.S. § 36-2853(A)): An adult who possesses more than 1 ounce but not more than 2.5 ounces of marijuana, of which not more than 12.5 grams is concentrate, commits a petty offense — a criminal classification, not a civil traffic violation.
  • Under-21 Tier (A.R.S. § 36-2853(B)): A person under 21 who possesses, consumes, or transports 1 ounce or less (no more than 5 grams concentrate) or consumption paraphernalia pays a civil penalty of up to $100 on a first violation, commits a petty offense on a second, and commits a class 1 misdemeanor on a third or subsequent violation.
  • Criminal Felony Tier (A.R.S. § 13-3405): Possessing more than 2.5 ounces of marijuana, possessing for sale, producing/cultivating without a license, or transporting marijuana across state lines remains a felony under A.R.S. § 13-3405.
  • Public Smoking Prohibited (A.R.S. § 36-2853(C)): Smoking marijuana in a public place or open space is a petty offense. Note that the statute reaches smoking specifically, not every form of consumption.

2. Prescription-Only Drugs (A.R.S. § 13-3406)

  • Prohibited Acts: Possessing, using, or administering a prescription-only drug (e.g., legend antibiotics, non-scheduled muscle relaxers, antihypertensives) without a valid medical prescription issued by a licensed medical practitioner.
  • Classification (A.R.S. § 13-3406(B)): Simple possession or use is a Class 1 misdemeanor; possessing a prescription-only drug for sale, or transporting, importing, or selling it, is a Class 6 felony; manufacturing, selling, or distributing a misbranded drug is a Class 4 felony. A mandatory $1,000 fine attaches to any conviction under this section.

3. Dangerous Drugs (A.R.S. § 13-3407)

  • Enumerated Substances: Defined under A.R.S. § 13-3401(6). Key examples include: Methamphetamine, amphetamines, hallucinogens (LSD, psilocybin mushrooms, mescaline, PCP), MDMA (Ecstasy), and anabolic steroids.
  • Classifications:
    • Possession or use: Class 4 felony.
    • Possession for sale: Class 2 felony.
    • Manufacture: Class 2 felony.
  • Methamphetamine Exception: Unlike other first-time drug offenders eligible for mandatory probation under Proposition 200 (A.R.S. § 13-901.01), methamphetamine offenders were excluded by statutory amendment in 2006; courts may impose flat prison sentences for methamphetamine offenses.

4. Narcotic Drugs (A.R.S. § 13-3408)

  • Enumerated Substances: Defined under A.R.S. § 13-3401(20). Includes opium, morphine, heroin, oxycodone, hydrocodone, fentanyl, and cocaine (both powder cocaine and cocaine base / crack).
  • Classifications:
    • Simple possession or use: Class 4 felony.
    • Possession for sale: Class 2 felony.
    • Transporting, importing, or selling: Class 2 felony.

5. Drug Paraphernalia (A.R.S. § 13-3415)

  • Definition: Any equipment, product, or material used, intended for use, or designed for use in planting, propagating, compounding, manufacturing, packaging, concealing, injecting, ingesting, or inhaling controlled substances. Examples: Glass meth pipes, hypodermic syringes without prescription, digital gram scales, chore boy, and glassine baggies.
  • Classification: Class 6 felony.
  • Testing Strips Decriminalized: Under Arizona legislative revisions, fentanyl drug testing strips designed to detect synthetic opioids are statutorily excluded from the definition of paraphernalia.

2. Statutory Threshold Amounts & Mandatory Prison (A.R.S. § 13-3401(36))

The statutory threshold amount is a specific quantity of a controlled substance codified in A.R.S. § 13-3401(36). If a defendant possesses a quantity of drugs equal to or exceeding the threshold amount, the law presumes the possession is for sale and mandates a term of imprisonment in the Arizona Department of Corrections, stripping the court of the discretion to grant probation.

Controlled SubstanceStatutory Threshold Amount (A.R.S. § 13-3401(36))Statutory Classification
Heroin1 gramNarcotic Drug (A.R.S. § 13-3408)
Cocaine (powder and hydrolyzed/base alike)9 gramsNarcotic Drug (A.R.S. § 13-3408)
Fentanyl and fentanyl mimetic substances9 gramsNarcotic Drug (A.R.S. § 13-3408)
Methamphetamine9 grams (including methamphetamine in liquid suspension)Dangerous Drug (A.R.S. § 13-3407)
Amphetamine9 grams (including amphetamine in liquid suspension)Dangerous Drug (A.R.S. § 13-3407)
PCP (Phencyclidine)4 grams or 50 millilitersDangerous Drug (A.R.S. § 13-3407)
LSD (Acid)one-half milliliter, or 50 dosage units in blotter formDangerous Drug (A.R.S. § 13-3407)
Marijuana2 poundsMarijuana (A.R.S. § 13-3405)
Any other unlawful substance (or a combination involving one)Value of at least $1,000Applicable Chapter 34 Statute

[!WARNING] AZPOST High-Yield Exam Point: Arizona no longer has a separate crack-cocaine threshold. A.R.S. § 13-3401(36)(b) sets a single 9-gram threshold for "cocaine, including hydrolyzed cocaine," so powder and base cocaine are measured identically. Older prep material still prints a 750-milligram crack tier and a 1-gram or 100-pill fentanyl tier; both are obsolete. Fentanyl now carries the same 9-gram threshold as methamphetamine, and combinations of the listed substances are aggregated under A.R.S. § 13-3420.


3. Fentanyl Officer Safety & Naloxone Protocols

Illicit synthetic fentanyl is a synthetic opioid 50 to 100 times more potent than morphine. It is frequently pressed into counterfeit prescription pills designed to replicate legitimate oxycodone 30mg tablets (commonly stamped "M30" and known as "blues").

[ Suspected Fentanyl Exposure ] ---> [ Assess Symptoms ] ---> [ Administer Naloxone ] ---> [ Call EMS ]
- Powder or crushed pills           - Pinpoint pupils         - 4mg intranasal spray       - Monitor breathing
- Nitrile gloves + N95 mask         - Shallow / agonal resp   - Repeat in 2-3 minutes       - Secondary dose if
- NO field sniffing or tasting      - Unresponsiveness, blue lips  if no respirations        no revival

Operational Handling Standards

  • Absorption Realities vs. Myths: Fentanyl cannot be rapidly absorbed through intact, dry skin in toxic amounts simply from brief accidental touch. However, mucous membrane contact (rubbing eyes, nose, mouth) or inhalation of airborne powder presents an acute, life-threatening overdose risk.
  • Personal Protective Equipment (PPE): Always wear nitrile gloves when handling suspected narcotics. Wear an N95 or N100 particulate respirator and eye protection if dealing with loose, disturbed powders. Never sniff, taste, or field-test suspected powders using open chemical testing pouches that generate airborne dust.

Naloxone (Narcan) Administration

  • Mechanism: Naloxone is an opioid receptor antagonist that displaces fentanyl from brain receptors, temporarily reversing respiratory depression.
  • Administration Protocol: Spray one pre-packaged 4mg dose into one nostril. If the subject does not resume spontaneous, regular breathing within 2 to 3 minutes, administer a second dose in the opposite nostril.
  • Post-Administration Management: Naloxone half-life is shorter than fentanyl; the subject may relapse into respiratory arrest once naloxone wears off. Always request immediate emergency medical transport (EMS) and position the revived individual in the recovery position.

4. Criminal Street Gangs & Member Validation Criteria

Organized criminal street gangs are aggressively targeted under Arizona statutes through sentence enhancements and distinct substantive crimes.

Statutory Definitions (A.R.S. § 13-105)

  • Criminal Street Gang (A.R.S. § 13-105(8)): An ongoing formal or informal association of persons in which members or associates individually or collectively engage in the commission, attempted commission, facilitation, or solicitation of any felony act and that has at least one individual who is a criminal street gang member.
    • Exam Trap: A common name or common identifying sign or symbol is NOT an element of the definition. Under A.R.S. § 13-2321(E) it is evidence that is admissible and may be considered in proving that a criminal street gang exists or that a person is a member. Older prep material recites it as part of the definition; that language is obsolete.
  • Criminal Street Gang Member (A.R.S. § 13-105(9)): An individual who meets at least TWO (2) of the following SEVEN (7) statutory criteria:
                     [ ARIZONA SEVEN STATUTORY GANG CRITERIA ]
                 (Must meet at least TWO criteria for validation)
                                       |
       +---------------+---------------+---------------+---------------+
       |               |               |               |               |
1. Self-        2. Witness      3. Written /    4. Paraphernalia 5. Tattoos
   Proclamation    Testimony       Electronic      or Photos        Documented

                       +---------------+---------------+---------------+
                       |                               |
               6. Clothing / Colors            7. Other Indicia
                  Gang style / attire             Hand signs, graffiti,
                                                  associating with members

Gang Substantive Offenses & Enhancements

  • Participating in a Criminal Street Gang (A.R.S. § 13-2321(A), (C)): A Class 2 felony committed by intentionally organizing, managing, directing, supervising, or financing a criminal street gang with intent to promote or further its criminal objectives.
  • Assisting a Criminal Street Gang (A.R.S. § 13-2321(B), (D)): A Class 3 felony committed by committing any felony offense for the benefit of, at the direction of, or in association with a criminal street gang.
    • Citation Trap: Do not confuse § 13-2321 with A.R.S. § 13-2308, which governs criminal syndicates (participating is a Class 2 felony; assisting is a Class 4 felony).
  • Gang Sentence Enhancement (A.R.S. § 13-714): A person convicted of any felony committed with intent to promote, further, or assist criminal conduct by a criminal street gang is ineligible for suspension of sentence, probation, pardon, or early release, and the presumptive, minimum, and maximum sentence is increased by three years for a class 4, 5, or 6 felony or increased by five years for a class 2 or 3 felony. The addition is in addition to any other enhanced sentence that applies.

5. Specific Property Crimes: Vehicle Theft & Joyriding

Arizona law draws a sharp, critical distinction between stealing a vehicle to permanently keep or strip it, versus temporarily taking a vehicle without permission (joyriding).

[ Unlawful Use of Means of Transportation (A.R.S. § 13-1803) ]     [ Theft of Means of Transportation (A.R.S. § 13-1814) ]
- Class 6 Felony                                                   - Class 3 Felony
- "Joyriding" - NO intent to permanently deprive owner            - Specific INTENT TO PERMANENTLY DEPRIVE owner
- Applies to unauthorized driver OR knowing passenger               - Or converting rental vehicle, obtaining by fraud

Theft of Means of Transportation (A.R.S. § 13-1814)

  • Classification: Class 3 felony.
  • Elements: A person commits theft of means of transportation if, without lawful authority, the person knowingly:
    1. Controls another person's means of transportation with the intent to permanently deprive the person of the vehicle; OR
    2. Converts for an unauthorized term or use another person's vehicle entrusted to them for a limited purpose (e.g., failing to return a rental car after receiving formal certified demand); OR
    3. Obtains control over another person's vehicle by a material misrepresentation or fraud.

Unlawful Use of Means of Transportation (A.R.S. § 13-1803)

  • Classification: Class 6 felony.
  • Elements: Commonly referred to as "joyriding." Committed when a person, without intent to permanently deprive, knowingly:
    1. Takes unauthorized control over another person's means of transportation; OR
    2. Is a passenger in a means of transportation, knowing or having reason to know that the vehicle is in the unauthorized control of another.

Chop Shops & Defaced VINs

  • Operating a Chop Shop (A.R.S. § 13-1817): A Class 4 felony. Committed by owning, operating, or maintaining any facility used to alter, dismantle, reassemble, or store stolen motor vehicles or parts for sale or distribution.
  • Defacing Serial Numbers / VINs (A.R.S. § 13-1807 / § 28-2165): A vehicle possesses three primary vehicle identification number (VIN) locations: the public VIN plate (lower driver's side windshield dash), the Federal Safety Certification label (driver's side B-pillar/door jamb), and secondary/confidential VINs stamped into hidden frame or engine components. Removing, defacing, altering, or falsifying a VIN is a Class 5 felony.

6. Financial Crimes, Identity Theft & Organized Retail Theft

  • Taking Identity of Another Person (A.R.S. § 13-2008): A Class 4 felony committed when a person knowingly takes, purchases, manufactures, records, possesses, or uses any personal identifying information or entity identifying information of another person or entity without consent, with the intent to obtain employment, credit, goods, services, or anything of value.
  • Aggravated Taking Identity of Another Person (A.R.S. § 13-2009): A Class 3 felony triggered when the offense involves:
    1. Identifying information of three or more separate persons or entities;
    2. Possessing or using five or more separate pieces of identifying information; OR
    3. Manufacturing counterfeit identity documents with intent to facilitate an unlawful purpose.
  • Organized Retail Theft (A.R.S. § 13-1819): A Class 4 felony committed when a person knowingly removes merchandise from a retail establishment without paying, with the intent to resell or trade the merchandise for value. The offense elevates to a Class 3 felony if the person uses an artifice, instrument, container, or device (e.g., booster bag) to facilitate the theft, or steals retail merchandise with an aggregate value of $1,500 or more within a 180-day period.

7. High-Yield Exam Traps & Real-World Application Scenario

High-Yield Exam Traps for Section 12.4

  1. Threshold Amounts: Heroin is 1 gram; cocaine (powder or hydrolyzed) is 9 grams; methamphetamine, amphetamine, and fentanyl are each 9 grams; PCP is 4 grams or 50 milliliters; LSD is one-half milliliter or 50 blotter dosage units; marijuana is 2 pounds. There is no separate crack-cocaine tier and no pill-count fentanyl tier.
  2. Joyriding vs. Grand Theft Auto: Theft of Means of Transportation (Class 3 felony) requires intent to permanently deprive. Unlawful Use of Means of Transportation (Class 6 felony) has NO intent to permanently deprive and also criminalizes knowing passengers.
  3. Gang Validation Requirement: A suspect must satisfy at least TWO of the seven statutory criteria under A.R.S. § 13-105(9).
  4. Prop 207 Limits: Legal possession is up to 1 ounce (max 5 grams concentrate) for adults 21+. Over 2.5 ounces remains a criminal felony.
  5. Organized Retail Theft (Class 4 vs Class 3): Theft to resell is a Class 4 felony; using a booster bag or artifice elevates the offense to a Class 3 felony.

Operational Application Scenario

Scenario: Officer Bradley initiates a traffic stop on a vehicle bearing a fictitious registration plate. Inside the vehicle are two occupants: a driver and a passenger. On the rear seat in plain view, Officer Bradley observes a digital gram scale and a plastic bag containing 14 grams of crystalline methamphetamine. A search of the center console yields a loaded handgun and a counterfeit driver's license bearing the passenger's photo with another citizen's name and social security number. A certified MVD query of the vehicle's confidential frame VIN reveals the vehicle was reported stolen by a rental agency three weeks ago after the driver failed to return it and disabled the GPS tracker. Both occupants display prominent documented street gang tattoos, and the driver admits in post-Miranda questioning that he is an active gang member.

  • Drug Offense Analysis: The crystalline substance is methamphetamine, a dangerous drug under A.R.S. § 13-3407. Because 14 grams exceeds the 9-gram statutory threshold under A.R.S. § 13-3401(36), the possession carries a mandatory prison sentence upon conviction.
  • Gang Validation: Both subjects meet the statutory criteria for Criminal Street Gang Member under A.R.S. § 13-105(9): the driver meets self-proclamation and tattoos (2 criteria); the passenger meets tattoos and associating with a member (2 criteria).
  • Vehicle Theft: The driver converted a rental vehicle with intent to permanently deprive, constituting Theft of Means of Transportation under A.R.S. § 13-1814 (Class 3 felony).
  • Identity Theft: Possessing another person's personal identifying information to obtain fraudulent identification constitutes Taking Identity of Another Person under A.R.S. § 13-2008 (Class 4 felony).
