Psilocybin law in Arizona
Illegal Checked 26 October 2026
Psilocybin is illegal in Arizona: it is a 'dangerous drug' under A.R.S. 13-3401, and possessing it is a class 4 felony that a court may reduce to a misdemeanor for some first offenders.
Psilocybin is a controlled substance with no lawful route for retreats or personal use. Some of these states fund research or trials. A summary of published sources, not legal advice.
Source status: Prohibited. Psilocybin remains a Schedule I drug under US federal law.
Scheduling
Arizona's criminal code lists psilocybin and psilocyn as hallucinogenic 'dangerous drugs' in A.R.S. 13-3401(6)(a)(xxxviii) and (xxxix), rather than using numbered schedules. [A.R.S. 13-3401, Definitions (dangerous drug), Arizona State Legislature, read 26 October 2026]

Penalties
- Knowingly possessing or using a dangerous drug is a class 4 felony; for a person with no prior felony or drug conviction, and unless the drug is LSD, methamphetamine, amphetamine or PCP, the court on the state's motion may enter a class 1 misdemeanor or defer designation pending probation (A.R.S. 13-3407(A)(1) and (B)(1)).
