What decriminalization actually means
Decriminalization is not the same as legalization. It means local law enforcement has been directed to make psilocybin possession their lowest priority — effectively, they won't arrest you for personal use. But there is no commercial framework. You cannot legally sell, operate a service center, or advertise a psilocybin business in a decriminalized city (unless the state has also legalized, as in Colorado).
What decriminalization does mean for entrepreneurs: it signals political will, it builds community awareness and demand, and it is almost always followed within a few years by a state-level legalization push. This is the cannabis playbook, step for step.
The pattern: City decriminalizes → more cities follow → state ballot measure → state legalization → commercial framework. Denver decriminalized in 2019. Colorado legalized statewide in 2022. That's three years.
Decriminalized cities as of 2026
Initiative 301 passed with 51% of the vote. Made personal possession and use of psilocybin mushrooms the lowest law enforcement priority. Now covered under Colorado's full state legalization.
City Council unanimously decriminalized all entheogenic plants and fungi, including psilocybin. One of the broadest decrim policies in the country. California state legalization efforts are ongoing.
City Council resolution making enforcement of entheogenic plant laws the lowest priority. Ann Arbor has a long history of progressive drug policy — it was also one of the first cities to decriminalize cannabis in the 1970s.
Initiative 81 passed with 76% of the vote — an overwhelming mandate. Made entheogenic plants and fungi lowest enforcement priority. A "gifting" gray market has emerged. Federal jurisdiction complicates full legalization.
City Council resolution decriminalizing personal use and possession of entheogenic plants including psilocybin mushrooms.
City Council decriminalized entheogenic plants. Boston followed shortly after. Massachusetts is considered a strong candidate for state legalization within the next 2-3 years.
City Council resolution mirroring Somerville's decriminalization, expanding the growing cluster of decrim cities in the greater Boston area.
Third Massachusetts city to decriminalize. The concentration of decrim cities in Massachusetts signals strong state-level momentum.
Proposal E passed with 61% of the vote, making entheogenic plants lowest enforcement priority. Follows Ann Arbor's lead and expands Michigan's decrim footprint.
City ordinance making psilocybin the lowest enforcement priority. Washington state has active legalization efforts underway.
What states are next?
Based on the pattern of decrim cities, legislative activity, and ballot initiative filings, the states most likely to pass psilocybin legalization frameworks in the next 3-5 years include:
- California — Multiple decrim cities, large progressive population, active legislation
- Massachusetts — Cluster of decrim cities, strong advocacy movement
- Washington — Seattle decrim, active state legislation
- Michigan — Ann Arbor + Detroit decrim, growing movement
- New Mexico — Natural medicine bill activity
- Nevada — Ballot initiative process favorable, active efforts
