Psilocybin therapy near Seattle: Oregon, Colorado and clinical trials

You can't legally get psilocybin therapy in Washington unless you're in a clinical trial. Three hours south, you can. Here's how Oregon's program works, what's changing there, what Colorado offers, and which Seattle studies are recruiting.

The short answer

  • In Washington, the only legal psilocybin is in approved clinical trials. Two were recruiting at Seattle sites in October 2026.
  • Oregon licenses service centers where adults 21+ take psilocybin with a trained facilitator. No residency or prescription needed. Individual sessions have commonly cost about $850 to $3,000.
  • Oregon's program is contracting: about half its licensed centers have let their licenses expire or surrendered them, and regulators have proposed sharply higher license fees from January 1, 2027.
  • Colorado has 47 licensed healing centers as of mid-2026, with some charging around $3,500.
  • An FDA decision on the first psilocybin medicine, Compass Pathways' COMP360 for treatment-resistant depression, could come in 2027; the company targets launch in the first half of that year if it's approved and rescheduled.

What's available in Washington

Psilocybin therapy isn't legal in Washington outside research. The state's one psilocybin law, passed in 2023, funded a University of Washington study rather than a program; that study enrolled veterans and first responders and is no longer recruiting. Bills for a regulated program stalled in 2025 and 2026 (details).

What Seattle does have:

  • Clinical trials recruiting at Seattle sites, listed below.
  • Ketamine-assisted therapy and esketamine. These aren't psilocybin, but they're the legal psychedelic-adjacent treatments available in Seattle now. Esketamine (Spravato) is FDA-approved for treatment-resistant depression, and clinics offer ketamine off-label under medical supervision.
  • Integration support from therapists who don't provide psilocybin but help people prepare for or make sense of an experience. That's legal, because no drug changes hands.

Oregon's licensed service centers

Since 2023, Oregon has licensed psilocybin service centers under Measure 109. It's not a medical program: you don't need a diagnosis or a prescription, and the facilitators aren't required to be clinicians. Anyone 21 or older can go, wherever they live. In 2025, Oregon's centers served 5,935 clients, 1,753 of them from other states (OHA data).

How a session works

  1. Preparation. A meeting with a licensed facilitator, where you complete a client information form. Screening can turn people away, for example anyone who's taken lithium in the last 30 days or has been diagnosed with active psychosis.
  2. Administration. At the service center, you buy and take psilocybin produced by a licensed manufacturer and tested by a licensed lab, and you stay under the facilitator's supervision until the effects wear off. Individual and group sessions are both offered.
  3. Integration. An optional follow-up meeting afterward.

You can't take any psilocybin home, and bringing psilocybin back into Washington would be illegal anyway.

What it costs

The state doesn't set prices. Reporting in 2026 put individual sessions at roughly $850 to $3,000; group sessions cost less. Add travel: Portland is about three hours from Seattle by car, a little longer by train. Insurance doesn't cover it.

What's changing in 2026 and 2027

  • Fewer centers. Of the 39 service centers licensed since 2023, about half have let their licenses expire or surrendered them, according to the Oregon Capital Chronicle. InnerTrek's Portland center, co-founded by Tom Eckert, one of the architects of Measure 109, closed in June 2026.
  • Higher fees. Regulators proposed doubling service center and manufacturer license fees and ending reduced fees for nonprofits, veterans and low-income licensees. The revised rules are scheduled to take effect January 1, 2027, and operators have warned that prices could rise.
  • A merged regulator. Budget problems led the Oregon Health Authority to combine Oregon Psilocybin Services with the medical marijuana program into a single section.
  • Out-of-state facilitators. A 2026 law, HB 4040, lets people trained in another state's approved program apply for Oregon facilitator licenses from 2027.
  • Local opt-outs. Many Oregon cities and counties have banned service centers. Redmond voters decide on November 3, 2026 whether to extend that city's ban.

Questions to ask a center before you book

  • What's included in the price, and what's the cancellation policy?
  • Who will my facilitator be, and what's their background beyond the required training?
  • How do you screen for medications and mental health history?
  • Individual or group, and how many people per facilitator?
  • What happens if I have a hard time during or after the session?

Colorado's healing centers

Colorado's Natural Medicine Health Act set up a similar licensed system. Applications opened at the end of 2024, and as of July 31, 2026 the state had approved 11 standard and 36 micro healing centers (Colorado Division of Natural Medicine). At least two centers were charging $3,500 in early 2026 (CPR). Colorado also lets adults 21 and older grow, use and share natural psychedelics at home without selling them, which Washington doesn't.

Clinical trials recruiting in Seattle

As of October 20, 2026, ClinicalTrials.gov listed these psilocybin-related studies recruiting at Seattle sites:

  • Psilocybin for veterans with treatment-resistant depression

    A Phase 3 VA trial enrolling about 240 veterans across five sites, including VA Puget Sound Health Care System's Seattle division. It started in August 2026. NCT07226232

  • CYB003 in major depressive disorder

    A Phase 3 trial of a modified psilocin molecule from Cybin, recruiting at the Seattle Neuropsychiatric Treatment Center; an Everett site was listed as not yet recruiting. NCT06793397

Two University of Washington studies are under way but no longer enrolling: PsiloStudy, the state-funded trial for veterans and first responders with PTSD and alcohol use disorder (NCT06853912), and a group psilocybin therapy study for people with advanced cancer at Fred Hutch. New studies appear often; search ClinicalTrials.gov for psilocybin near Seattle for the current list.

When psilocybin might reach a pharmacy

The first psilocybin medicine is getting close. Compass Pathways' COMP360 met its main goal in two Phase 3 trials for treatment-resistant depression, in June 2025 and February 2026. In April 2026 the FDA gave it a Commissioner's National Priority Voucher, which can shorten review to one to two months once an application is complete, and Compass said in August that it expected to finish filing in the fourth quarter of 2026, with a launch targeted for the first half of 2027 if the FDA approves it and the DEA reschedules it (Compass). An April 2026 executive order directed agencies to speed up review and rescheduling of psychedelic drugs that complete Phase 3 trials (EO 14401).

Approval would make one specific psilocybin product a prescription treatment given in a clinic with monitoring, much like esketamine today. It wouldn't make mushrooms legal, in Washington or anywhere else.

Retreats abroad

Some Seattle residents travel to psilocybin retreats in countries where it's legal or tolerated (Axios Seattle). No US regulator oversees them, and screening, staff training and emergency plans vary widely. Ask the same questions you'd ask an Oregon center, and check what medical care is nearby.

Common questions

Is psilocybin therapy legal in Washington?

Only inside approved clinical trials. Washington funded a University of Washington study in 2023, but bills to create a legal psilocybin program stalled in 2025 and 2026. Anyone offering psilocybin sessions for a fee in Washington is operating outside the law.

Do I have to live in Oregon to get psilocybin services there?

No. Oregon's program is open to anyone 21 or older, and in 2025 more than 1,700 clients came from other states. You take the psilocybin at the service center during a supervised session and can't take any home.

How much does psilocybin therapy cost in Oregon?

Prices aren't set by the state and vary by center. Individual sessions have commonly cost about $850 to $3,000, including preparation and the administration session; group sessions are cheaper. Expect prices to change as license fees rise in 2027.

Does insurance cover psilocybin services?

Generally no. Oregon's psilocybin services aren't a medical treatment and aren't billed to health insurance. Clinical trials are free to participants.

When will psilocybin be FDA approved?

Compass Pathways expects to finish submitting its application for COMP360 in late 2026 and holds an FDA priority voucher that could shorten review. It targets a launch in the first half of 2027, subject to FDA approval and the DEA rescheduling the product. Approval would make it a prescription treatment given in clinics, not something sold in stores.
