Ann Arbor was the first U.S. city to pass a local entheogenic plant policy covering psilocybin mushrooms, and commercial psilocybin sales, retail retreat centers and paid mushroom trips remain illegal under Michigan law. The Ann Arbor City Council approved the resolution on September 21, 2020, making investigation and arrest for certain entheogenic plant activity the city’s lowest law enforcement priority.
What Ann Arbor allows for psilocybin
If you are searching for psilocybin retreats in Ann Arbor, you should separate local police priority from legal commercial access. Ann Arbor lowered local enforcement priority for certain activity involving entheogenic plants and plant compounds on the federal Schedule I list. That includes planting, cultivating, purchasing, transporting, distributing, engaging in practices with or possessing those plants or compounds.
You should read the city rule as a local enforcement policy. It does not create a Michigan psilocybin license. It does not create a state-approved retreat market. It does not give a business permission to sell mushrooms, sell guided trips or operate a retail retreat center.
The strongest local protection is tied to personal activity. Once money, advertising, dosing support, product handling or organized commercial service enters the picture, the legal risk changes.
What the Ann Arbor resolution says
The 2020 Ann Arbor resolution states that investigation and arrest of people for planting, cultivating, purchasing, transporting, distributing, engaging in practices with or possessing entheogenic plants or plant compounds on the federal Schedule I list shall be the city’s lowest law enforcement priority.
The city also stated that city funds or resources should not be used for investigation, detention, arrest or prosecution arising from alleged violations of state and federal law regarding entheogenic plant use. An earlier full resolution copy also states that commercial sales or manufacturing, possession or distribution in schools, impaired driving and public disturbance are not authorized.
You should pay close attention to those limits. The city lowered local priority for some conduct. It also kept public safety, schools, impaired driving and commercial activity outside the protection of the policy.
Why commercial sales remain illegal
Commercial psilocybin sales remain illegal because Michigan law still controls the larger legal status of psilocybin. A city resolution cannot remove psilocybin from state controlled-substance law. It also cannot create a legal supply chain, product testing system, facilitator license or retreat-center permit.
You should be cautious with any provider that says Ann Arbor legalized mushroom sales. Ann Arbor made certain entheogen-related enforcement a low priority. A legal retail sales system would need state law, licensing rules and business standards.
A paid retreat can involve more than personal possession. If the provider supplies mushrooms, stores them, measures doses, collects payment or arranges access, the activity may be reviewed as sale, distribution or facilitation. A donation label or private membership label does not remove that risk.
Washtenaw County policy and its limits
Ann Arbor’s local policy later influenced county-level practice. The Washtenaw County Prosecuting Attorney’s Office issued Policy Directive 2021-06, stating a general presumption against criminal charges for personal use, possession and cultivation of entheogenic plants. The same policy also described a general presumption against charges tied to small-scale sale or distribution, with limits.
You should read that county policy carefully. A prosecutorial presumption is not full legalization. The policy does not bind state police, federal officials or every possible future prosecutor. It also does not create a business license for a retail retreat center.
The county policy can reduce local prosecution risk in some cases. It does not make Ann Arbor a fully legal mushroom tourism market.
Personal use inside Ann Arbor
If you are focused on personal use, Ann Arbor’s policy may reduce local enforcement risk inside city limits. The city resolution covers activity involving entheogenic plants and plant compounds, including psilocybin mushrooms.
You should still keep the city border in mind. Ann Arbor’s policy applies to Ann Arbor’s local enforcement approach. It does not apply across all Michigan cities. It does not apply at airports, on federal property or outside the city.
You should also avoid impaired driving, public disturbance and activity involving schools. Those areas were kept outside the local protection in the resolution text.
Retail retreat centers and paid guides
If a provider advertises a retail retreat center in Ann Arbor, you should ask direct legal questions. Ask if psilocybin is supplied. Ask who supplies it. Ask if payment covers access, dosing, facilitation or a group session. Ask what Michigan law allows the provider to do.
You should also ask if the provider is relying only on Ann Arbor’s local resolution. If so, the answer does not support a retail retreat model. The city policy speaks to local enforcement priority. It does not authorize commercial sales or manufacturing.
You should be careful with soft labels such as private session, plant medicine circle, donation-based support, church work or integration weekend. Those phrases do not create a Michigan license.
A provider who avoids legal questions may also avoid safety questions. Ask about screening, medication review, consent, transportation and emergency support before booking anything.
Ann Arbor and Michigan law
Michigan’s larger legal setting remains restrictive. A 2026 legal review lists Michigan as a state where psilocybin remains controlled, private personal use is not decriminalized at the state level and regulated supported adult or medical use is not permitted.
You should treat Ann Arbor as a local decriminalization city, not a statewide legal access market. The city can set local priorities. Michigan has not created an Oregon-style service center model or a Colorado-style natural medicine framework.
This distinction is especially relevant because Ann Arbor has visible research activity and public discussion around psychedelics. Research interest does not authorize public sales. The University of Michigan’s psychedelic research center notes that psychedelic therapy is not available there and that psychedelics remain illegal at the federal level.
Ann Arbor compared with Detroit and Hazel Park
Ann Arbor was an early Michigan city on local entheogen policy. Detroit later approved Proposal E in 2021, and Hazel Park passed a related local measure in 2022. Public reporting has grouped these cities as part of Michigan’s local reform pattern.
You should review each city separately. Ann Arbor’s policy applies inside Ann Arbor. Detroit’s policy applies inside Detroit. Hazel Park’s policy applies inside Hazel Park. None of those local actions creates a single statewide retreat market.
If a provider uses Ann Arbor’s reputation to promote services elsewhere in Michigan, ask where the session happens and what local policy applies. Then ask what state law allows the commercial part of the service.
What visitors should know before booking
If you are visiting Ann Arbor, you should treat psilocybin as legally restricted. Do not assume the city has a legal retail market. Do not assume a delivery service, private guide or retreat listing is protected.
You should avoid carrying psilocybin across state lines, airports or federal land. You should also avoid public use, impaired driving and conduct near schools.
If you attend any legal non-psilocybin retreat activity in Ann Arbor, separate that from mushroom access. Lodging, meditation, breathwork, meals and group support may be lawful on their own. Supplying or using psilocybin creates a separate legal issue.
Key legal point for Ann Arbor
Ann Arbor lowered local enforcement priority for certain entheogenic plant activity in 2020. The city did not create a legal retail mushroom market or a licensed psilocybin retreat system.
Personal activity may receive low local priority inside Ann Arbor. Commercial mushroom sales, retail retreat centers and paid guided trips remain legally risky under the larger Michigan framework.
Conclusion
We follow Ann Arbor and Michigan psilocybin law because local decriminalization can be easy to overread. Local priority, county prosecution policy and commercial retreat activity should be reviewed as separate issues.
