Canadian Psychedelic Policy & Access 5 min read • Updated 2026-09-19

Is magic mushroom illegal in the US?

At the federal level, psilocybin is a Schedule I controlled substance in the US. However, sweeping state and municipal policy reforms have created regulated therapeutic and decriminalized access.

The US Regulatory Landscape: Federal Law vs State Initiatives

The legal status of magic mushrooms (psilocybin) in the United States is rapidly evolving, creating a nuanced patchwork between federal prohibition, state-regulated frameworks, and municipal decriminalization.

1. Federal Law: Schedule I Controlled Substances Act

Under the United States Controlled Substances Act (CSA) of 1970, psilocybin and psilocin are classified as Schedule I controlled substances. At the federal level, possession, manufacture, and distribution remain illegal outside of DEA-licensed clinical research protocols.

However, in 2018 and 2019, the US Food and Drug Administration (FDA) granted psilocybin Breakthrough Therapy Designation for Major Depressive Disorder (MDD) and Treatment-Resistant Depression (TRD), accelerating clinical trials aimed at eventual federal prescription reclassification.

2. State-Regulated Access Models

Several states have enacted historic voter initiatives and legislative reforms to establish legal access:

  • Oregon (Measure 109): Enacted in 2020, establishing the nation’s first licensed psilocybin facilitation model. Adults 21+ can legally receive supervised psilocybin sessions at licensed service centers without requiring a medical diagnosis.
  • Colorado (Proposition 122 / Natural Medicine Health Act): Passed in 2022, decriminalizing personal possession, cultivation, and sharing of natural psychedelics (psilocybin, DMT, mescaline), while establishing a state-licensed healing center regulatory framework.
  • California, Massachusetts & Other States: Active state-level legislative bills and ballot measures continue to advance decriminalization and research access.

3. Municipal Decriminalization ("Lowest Law Enforcement Priority")

Over a dozen major US cities have passed municipal resolutions directing local law enforcement to make natural entheogenic plants and fungi the lowest law enforcement priority:

  • Denver, CO: First US city to decriminalize psilocybin (May 2019).
  • Oakland & Santa Cruz, CA: Decriminalized all entheogenic plants and fungi.
  • Seattle, WA & Ann Arbor, MI: Enacted municipal non-enforcement protections.
  • Washington, D.C. (Initiative 81): Passed with over 76% voter approval.

Comparison with Canada

In Canada, psilocybin is classified under Schedule III of the Controlled Drugs and Substances Act (CDSA), but operating under municipal harm-reduction priorities and Health Canada Special Access Programs (SAP), resulting in a vibrant mail-order dispensary network delivering nationwide with full privacy protections.
