Psychedelic therapy in San Diego: every legal option in 2026

You can't legally get psilocybin therapy in San Diego today. Psilocybin is illegal under California and federal law, and the state has no license for psilocybin facilitators. What San Diegans can do legally is see a licensed clinician for ketamine-based treatment, join a registered clinical trial, or travel to Oregon, whose state-licensed program takes adults 21 and over from any state, or Colorado, which licenses healing centers (check its rules for visitors).

This guide walks through each route, what's changing at the FDA, and how to spot a provider you shouldn't trust. It's general information, not medical or legal advice.

Is psilocybin therapy legal in San Diego?

No. Possessing psilocybin in California is a misdemeanor under Health and Safety Code 11377, with up to a year in county jail.¹ No California law creates a way to give it to clients outside research, so anyone offering "psilocybin therapy" in San Diego is working outside the law, however professional the website looks. Our San Diego legal guide covers the penalties in detail.

California has tried several times:

• SB 58 (2023) would have decriminalized small amounts of natural psychedelics for adults. Governor Newsom vetoed it on October 7, 2023, saying he couldn't decriminalize "prior to these guidelines going into place" and asking lawmakers for a bill with therapeutic guidelines, safeguards against exploitation and medical screening.²
• SB 1012 (2024) would have allowed supervised use with licensed facilitators. It was held in committee in May 2024 and died.³
• SB 803 (2024), the "Heal Our Heroes Act," would have run a psilocybin pilot for veterans and former first responders in San Francisco, Santa Cruz and San Diego counties. Its sponsors pulled it in June 2024.⁴
• SB 751 (2025), a university-run pilot for veterans and first responders, died in February 2026.⁵

There's also no psilocybin or psychedelics measure on California's November 3, 2026 ballot.⁶

What are the legal options for psychedelic therapy?

Ketamine and esketamine

Ketamine is a legal prescription drug that some licensed clinicians use off-label for depression, and esketamine is a related nasal medication. Neither is psilocybin. They work differently, the sessions feel different, and the evidence behind them is separate, so don't treat a ketamine clinic as a stand-in for the psilocybin trials you've read about.

Both are being studied in San Diego. UC San Diego is testing nasal esketamine with brief cognitive behavioral therapy for people with treatment-resistant depression and suicidal thoughts, and has a planned trial pairing ketamine-assisted psychotherapy with a mindfulness program for opioid use disorder.^7,8

If you're considering a clinic, ask the prescriber what the drug is approved for and whether your use would be off-label, what medical screening they do, how you'll be monitored during and after each session, and the full cost of a course of treatment before you start. We don't list or rank clinics.

Clinical trials

A registered clinical trial is the only legal way to receive psilocybin in California. As of October 20, 2026, the one San Diego psilocybin trial listed as recruiting on ClinicalTrials.gov is UC San Diego's study of psilocybin-assisted therapy for physician burnout (NCT06814522), which is open only to UC San Diego doctors.^9,10 The university's Center for Psychedelic Research also lists a phantom-limb brain-imaging study as recruiting.¹¹ Watch UC San Diego's psilocybin trial portal for new studies, and see our guide to psilocybin research in San Diego for every local trial and what joining involves.

Oregon psilocybin service centers

Oregon was the first state to license supervised psilocybin services, under Measure 109. Service centers began serving clients in summer 2023.¹² According to the Oregon Health Authority:

• Clients must be 21 or older and "do not need to live in Oregon." No prescription is needed.
• A preparation session is required before the administration session.
• Psilocybin can only be bought at a licensed service center during an administration session and "may not be purchased and taken off-site."
• Exclusion criteria include active psychosis, taking lithium within the past 30 days, and thoughts of harming yourself or others.¹²

The state publishes a licensee directory so you can check a service center or facilitator before you book.¹³ Prices are set by each center, so ask for the total, including the preparation and any follow-up sessions.

How has it gone? A study of 346 clients in Oregon's program published in JAMA Network Open in August 2026 found 4 people (1.2%, all first-time psychedelic users) had behavioral reactions that needed medical attention, and 2.3% rated the experience as harmful three months later.¹⁴ That's a supervised, screened setting; risks outside one are harder to measure.

Colorado healing centers

Colorado voters approved Proposition 122 in November 2022, and the state's Natural Medicine Division licenses healing centers. As of October 16, 2026, it had approved 47 healing centers (11 standard and 36 "micro" centers).¹⁵ Colorado also lets adults 21 and over use and share natural psychedelics privately, without payment; selling them is prohibited.¹⁶

We couldn't confirm on an official page whether out-of-state visitors can use Colorado healing centers, so check the Natural Medicine Division's current rules before you plan a trip. Facilitators' licenses can be checked through Colorado's license lookup, linked from the state's natural medicine page.¹⁷

New Mexico's medical program (not open yet)

New Mexico's Medical Psilocybin Act, signed in April 2025 and effective June 20, 2025, creates a medical program for conditions including treatment-resistant depression, PTSD, substance use disorders and end-of-life care. The law requires the Department of Health to launch it by December 31, 2027.¹⁸ It wasn't operating as of October 1, 2026, with a launch targeted for late 2026.¹⁹ It will require a medical referral and a qualifying condition, and the statute doesn't say whether non-residents can enroll, so watch the Department of Health's program page.²⁰

Integration therapy

"Integration" means working through a psychedelic experience afterward, or preparing for one you'll have somewhere legal. Talking about it with a licensed therapist is ordinary therapy; what a therapist can't do in California is supply or administer psilocybin. If you're looking for one, ask how much experience they have with psychedelic-related issues and whether they'll coordinate with your doctor.

For support between sessions, the Fireside Project runs a free psychedelic peer support line, by call or text at 62-FIRESIDE (623-473-7433), that also helps people make sense of experiences afterward. It's not a crisis line.²¹

Retreats in Baja and Tijuana

Retreats across the border advertise heavily to San Diegans, often to veterans. They operate outside U.S. medical oversight, quality varies widely, and the legal risk doesn't end at the retreat: carrying any of it back through San Ysidro or Otay Mesa is a federal importation offense. Read our guide to psychedelic retreats in Tijuana and Baja before you consider one.

When could psilocybin therapy become legal in California?

The likeliest path isn't a state law. It's an FDA-approved psilocybin drug.

• Compass Pathways' COMP360, a psilocybin drug for treatment-resistant depression, is in a rolling FDA application. As of August 5, 2026, Compass said it had submitted some modules and was "on track to complete all modules in Q4," with a launch expected in the first half of 2027 "subject to FDA approval and following [DEA] rescheduling." No FDA decision date has been disclosed.²² UC San Diego and other La Jolla sites took part in its Phase 3 trials.
• Federal action. Executive Order 14401, signed April 18, 2026, directed the FDA to issue Commissioner's National Priority Vouchers to breakthrough psychedelic drugs and told the Attorney General to start rescheduling reviews for drugs that complete Phase 3. It set no deadlines and didn't reschedule anything.²³ The FDA awarded national priority vouchers to Compass and to the Usona Institute's psilocybin on April 24, 2026.²⁴ Psilocybin remains a Schedule I drug.²⁵
• California is ready to follow. AB 1021, by Assemblymember Buffy Wicks and signed in 2023, lets California health professionals prescribe and dispense a Schedule I drug's FDA-approved, federally rescheduled product without waiting for a new state law. Its author said it "does not decriminalize or legalize any controlled substance for any nonmedical use."²⁶

So if COMP360 is approved and rescheduled, San Diego psychiatrists could likely prescribe it for its approved use, probably under medical supervision. That's a prescription treatment for a specific condition, not legal mushrooms. The FDA's September 2026 public hearing also aired real caution: speakers cited estimates of serious adverse events in about 4% of trial participants with existing psychiatric conditions.²⁷

On the research side, California's AB 1103 (by San Diego Assemblymember Chris Ward) speeds up state approval of psychedelic studies through January 1, 2028, and the 2026 budget added $4.7 million for veterans' psychedelic research.^28,29 Neither makes therapy available outside research.

How do you spot an unsafe psychedelic provider?

Underground "facilitators" advertise in San Diego on social media and by word of mouth. They aren't licensed, because no license exists here. Any psilocybin facilitator in California is operating outside the law. These signs mark an unsafe or fraudulent provider anywhere, including in Oregon and Colorado:

• They claim to be "licensed" for psilocybin in California. There's no such license.
• They skip medical and psychiatric screening: heart conditions, lithium and other medications, and any personal or family history of psychosis or bipolar disorder.
• There's no sober sitter and no plan for a medical emergency.
• They push multi-session "packages," or want cash or crypto only.
• They can't tell you what the product is or where it came from.
• They promise a cure, or tell you not to talk to your own doctor.
• They mix in other substances, or touch you without your clear, prior consent.

For Oregon and Colorado, verify a license in the state's directory before paying anything. Our psilocybin safety guide covers drug interactions and who should avoid psilocybin entirely.

What about veterans and service members?

Much of California's recent psychedelic policy was driven by veterans' groups, and San Diego lawmakers carried several of the bills. Active-duty service members face a separate rule: military law bans psilocybin use anywhere, including in states where it's legal. Our guide for San Diego veterans covers research access, the VA's 2026 psilocybin trial and the rules for service members.
