What city psilocybin decriminalization means (and does not mean)

Cities that decriminalized psilocybin have passed resolutions telling local police to deprioritize enforcement. Most resolutions name psilocybin specifically. Many also cover other "entheogenic plants," meaning ayahuasca, mescaline-containing cacti, and ibogaine.

These resolutions do not legalize psilocybin. They do not create dispensaries, retreats, or any legal way to buy mushrooms. Federal law still classifies psilocybin as Schedule I. State law in most of these cities also keeps psilocybin illegal.

What changes is enforcement priority. Local police are told to focus on other drug crimes. Possession arrests drop sharply. But possession is still technically illegal, and state troopers or federal agents can still enforce the law.

What the resolutions usually cover

Commercial sale is almost never covered. Selling psilocybin remains a serious felony in every city on this list.

Full list by state

California — 6 cities

California has the most cities of any state that have decriminalized entheogens. The state itself has not — SB 58 was vetoed in 2023; SB 751 is moving in 2026.

  • Oakland (June 2019) — first city to decriminalize all entheogens, not just psilocybin. City council unanimous.
  • Santa Cruz (January 2020) — second California city; commercial sale stays illegal.
  • Arcata (October 2021) — small Humboldt County city; broad entheogen language.
  • San Francisco (September 2022) — Board of Supervisors unanimous.
  • Berkeley (July 2023) — fifth California city; covers entheogenic plants and fungi.
  • Eureka (October 2023) — sixth California city; unanimous council vote.

See our California legal status page for the full state picture, including SB 751.

Massachusetts — 8 cities and towns

The largest single-state cluster. Massachusetts voters defeated Question 4 in 2024, but city-level momentum continues.

  • Somerville (January 2021) — first in MA; covers ibogaine explicitly.
  • Cambridge (February 2021) — followed Somerville by weeks.
  • Northampton (March 2021)
  • Easthampton (October 2021) — non-binding council resolution.
  • Amherst (July 2022)
  • Salem (May 2023)
  • Provincetown (December 2023)
  • Medford (February 2024)

See our Massachusetts legal status page for state-level context.

Michigan — 6 cities plus Washtenaw County

The Detroit metro area dominates this cluster. Detroit's 2021 ballot initiative was the first US city decrim measure approved by voters rather than council.

  • Ann Arbor (September 2020) — first in MI; council unanimous.
  • Washtenaw County (January 2021) — county prosecutor announced no charges for natural psychedelics.
  • Detroit (November 2021) — Proposal E ballot measure, 61% voter approval.
  • Hazel Park (March 2022)
  • Ferndale (February 2023)
  • Ypsilanti (January 2024)

See our Michigan legal status page for the full state picture.

Washington — 5 cities plus 2 counties

Fastest-growing 2024–2026 cluster. The state itself has a psilocybin pilot research bill but no commercial program.

  • Seattle (October 2021)
  • Port Townsend (December 2021) — restricted to non-public use.
  • Jefferson County (May 2023)
  • Olympia (August 2024)
  • Tacoma (January 2025) — broad chemical-class language (tryptamines, phenethylamines, indolamines).
  • King County (March 2026) — covers Seattle metro area.

See our Washington legal status page.

Other states with one or two cities

  • Washington, D.C. (March 2021) — Initiative 81 covers psilocybin, ayahuasca, and mescaline. DC has unique federal jurisdiction issues.
  • Minneapolis, Minnesota (July 2023) — by mayoral executive order.
  • Portland, Maine (October 2023) — first New England city outside Massachusetts.

These three terms get used loosely. They mean different things for what you can legally do.

Term What it means Where it applies
Decriminalization Police told to deprioritize enforcement. Possession is still illegal — just rarely prosecuted locally. No legal way to buy. 30+ US cities (this page).
Legalization (statewide) State law permits possession. Federal law still applies. Colorado (Prop 122 for natural psychedelics, 2022).
Regulated access A licensed program where adults can legally use the drug in supervised settings. Oregon (Measure 109 psilocybin service centers, 2023). Colorado healing centers, expected 2025+.

If you want legal access to psilocybin in the US, the only options are Oregon's service centers or Colorado's coming healing centers. A decriminalized city does not have a legal supply.

What changed in 2025–2026

The pace of city decriminalization has not slowed. The most active cluster in 2025–2026 is Washington state.

Frequently asked questions

How many US cities have decriminalized psilocybin?

About 30 US cities and counties across 12 states have decriminalized psilocybin or all entheogenic plants. Massachusetts has the most (8 cities), followed by California (6), Michigan (6 plus Washtenaw County), and Washington (5 plus 2 counties). Denver was the first US city to decriminalize psilocybin, in May 2019.

What was the first US city to decriminalize psilocybin?

Denver, Colorado, was the first US city to decriminalize psilocybin mushrooms. Initiative 301 passed on May 7, 2019 with 50.6% voter approval. It directed Denver police to treat personal possession of psilocybin by adults 21+ as the lowest law enforcement priority.

Does city decriminalization mean psilocybin is legal there?

No. City decriminalization tells local police to deprioritize enforcement — possession is still illegal under state and federal law. There is no legal way to buy psilocybin in any decriminalized city. State troopers and federal agents can still enforce drug laws. Only Oregon's Measure 109 service centers and Colorado's upcoming healing centers offer legal regulated access.

Which state has the most cities that decriminalized psilocybin?

Massachusetts has the most cities, with 8 jurisdictions that have passed decriminalization measures: Somerville (2021), Cambridge (2021), Northampton (2021), Easthampton (2021), Amherst (2022), Salem (2023), Provincetown (2023), and Medford (2024). The state itself voted down Question 4 in 2024, but the city-level momentum has continued.

What did Detroit's Proposal E do?

Detroit's Proposal E (November 2021) was the first ballot initiative in any US city to decriminalize entheogens. It passed with 61% voter approval and made personal possession and therapeutic use of entheogenic plants by adults the lowest law enforcement priority in Detroit. Commercial sale remains illegal under Michigan state law.

What is the difference between psilocybin decriminalization and legalization?

Decriminalization removes or reduces criminal penalties but does not create legal access. Possession is still technically illegal — just rarely prosecuted locally. Legalization means a state has set up a regulated program where adults can legally use the drug in licensed settings. Oregon and Colorado are legalized; Detroit, DC, Oakland, and the others are decriminalized only.
