Buying mushrooms in Oregon works two completely different ways depending on what kind you want. Culinary varieties like button, cremini, shiitake, chanterelles, and morels are sold at grocery stores and farmers’ markets under ordinary food rules. Psilocybin mushrooms are not sold to take home at all. Under Oregon law, you can only purchase and consume psilocybin products on-site at a licensed service center, supervised by a licensed facilitator.
Culinary Mushrooms at Stores and Markets
Commercially cultivated mushrooms are available at any grocery store and follow standard food safety regulations. There are no special requirements for the buyer. Button, cremini, shiitake, and oyster mushrooms are shelf items like any other produce.
Wild-Foraged Mushrooms
Oregon’s forests produce chanterelles, morels, matsutake, and porcini, and these show up regularly at farmers’ markets and specialty stores, especially in fall. State regulations require that wild mushrooms sold commercially be identified by someone with recognized training in mushroom identification. Sellers must maintain written buyer specifications documenting the scientific and common name of each species, the identity and qualifications of the person who identified the mushroom, and contact information for the seller. These records must be kept on file for 90 days from the date of sale.
When you buy wild mushrooms, look for labeling that includes both the common and scientific name. Wild-foraged mushrooms sold in Oregon must also carry a notice stating they are not an inspected product. That label is not a warning about safety; it is a legal requirement distinguishing foraged product from commercially farmed product. If a seller cannot tell you what species you are buying or who identified the mushrooms, find a different vendor.
Psilocybin Is a Supervised Service, Not a Purchase
The most important thing to understand about psilocybin in Oregon is that there is nothing to take home. Under ORS 475A.498, you can only purchase, possess, and consume psilocybin products at a licensed service center, and only while supervised by a licensed facilitator.1Oregon State Legislature. Oregon Revised Statutes Chapter 475A – Psilocybin Regulation Service centers cannot let you bring psilocybin products onto the premises or remove any product from the facility.2Legal Information Institute. Oregon Administrative Code 333-333-4480 – Service Center Privileges and Prohibitions It is closer to paying for a guided medical procedure than shopping for a product.
The Oregon Health Authority publishes a licensee directory listing service centers that have consented to share their contact information publicly.3Oregon Health Authority. Oregon Psilocybin Services – Service Center License
Who Can Access Psilocybin Services
You must be at least 21 years old.4Oregon Health Authority. Oregon Psilocybin Services – Access Psilocybin Services There is no residency requirement, so visitors from other states can participate.1Oregon State Legislature.

What Psilocybin Services Cost
Sessions are expensive, and insurance does not cover them. Private individual sessions generally run between $900 and $1,500 or more, depending on dosage and facility. Group sessions bring the price closer to $500 per person. Low-dose sessions at some centers start around $300. Oregon also applies a 15% state tax on psilocybin products on top of session and facility fees.
Steps Before You Can Consume
Oregon law requires three things before you consume anything at a service center: a client information form, a preparation session, and a signed informed consent document. Skipping any of them disqualifies you from proceeding.
Client Information Form
You fill out a standardized health screening form published by the Oregon Health Authority. It asks whether you have taken lithium in the past 30 days, whether you have been diagnosed with or treated for active psychosis, whether you are pregnant or breastfeeding, and whether you have a history of self-harm, among other questions.7Legal Information Institute. Oregon Administrative Code 333-333-5050 – Client Information Form The completed form goes to both the service center operator and your assigned facilitator so they can assess whether the session is appropriate.8Oregon Public Law. Oregon Code 475A.350 – Client Information Form
Preparation Session
You must attend a preparation session with a licensed facilitator before any administration session can be scheduled. It does not have to happen at the service center; it can take place at another location.9Oregon Public Law. Oregon Code 475A.345 – Preparation Session The facilitator reviews your health screening form, discusses your intentions, and walks you through what the experience involves. The facilitator must certify that you completed this step before the service center schedules your administration appointment.
Informed Consent
Before the session, you sign an informed consent document describing potential side effects including nausea, anxiety, confusion, elevated blood pressure and heart rate, altered perception, reduced inhibitions, and the possibility of recovering repressed memories or past traumas. The form also notes that unanticipated side effects may occur.10Legal Information Institute. Oregon Administrative Code 333-333-5040 – Informed Consent You initial each section and sign before the administration session can begin.
What Happens During the Session
You consume the psilocybin product on-site. A facilitator stays with you throughout the session. The length depends on dosage and individual reaction, and you cannot leave the facility while the session is underway. When it concludes, you sign a release document confirming you agree to end the session and follow your pre-arranged transportation plan.11Legal Information Institute. Oregon Administrative Code 333-333-5250 – Duration of Administration Session Driving yourself home afterward is not an option, so arrange a designated driver or rideshare in advance.
An integration session is available afterward to help you process the experience. It is not legally required the way the preparation session is.
Psilocybin Outside the Licensed System Is Still Illegal
Oregon’s regulated program creates a narrow legal exception, not a blanket legalization. The statute states that manufacturing, delivering, or possessing psilocybin products is lawful only when done in full compliance with ORS Chapter 475A.1Oregon State Legislature. Oregon Revised Statutes Chapter 475A – Psilocybin Regulation Buying psilocybin mushrooms from an unlicensed seller, growing them at home, or possessing them anywhere outside a licensed service center falls outside this exception.
Oregon also recriminalized personal drug possession effective September 1, 2024, through House Bill 4002, reversing the earlier decriminalization under Measure 110.12Oregon State Legislature. HB4002 2024 Regular Session Possession of controlled substances outside a licensed context is once again a misdemeanor.
At the federal level, psilocybin remains a Schedule I controlled substance under 21 U.S.C. ยง 812.13Office of the Law Revision Counsel. 21 USC 812 – Schedules of Controlled Substances Participating in a state-legal program does not create any protection under federal law.
