Psilocybin retreats in California remain a topic of strong interest in 2025. While there are no fully licensed psilocybin retreat centers open to the public in the state, important legislative efforts and pilot programs are laying the foundation for future legal retreats. California residents seeking psilocybin experiences currently travel to international destinations where the practice is legal, while inside the state limited research and harm reduction groups provide education and preparation.
Current Legal Status of Psilocybin in California
California has not legalized psilocybin for commercial retreats. The substance is still classified as illegal under both federal and state law. However, the state has been at the center of major reform efforts. Senate Bill 58, signed into law in 2023, decriminalized the personal possession and use of psilocybin and certain other natural psychedelics for adults beginning in 2025. While this law does not permit retail sales or retreat operations, it creates a legal space where individuals will not face criminal charges for holding or consuming personal amounts.
This development means retreats cannot yet operate openly in California, but it sets the stage for supervised, licensed programs in the coming years.
California Psilocybin Policy and Future Outlook
Decriminalization Measures
-
SB 58 covers psilocybin, psilocin, mescaline (not peyote), and DMT.
-
The law allows adults to possess and use these substances for personal use.
-
Sharing within community or ceremony contexts is tolerated, but sales remain prohibited.
Proposed Pilot Programs
California lawmakers continue to discuss pathways for psilocybin-assisted therapy and retreat-style healing. Draft bills and proposals have outlined the possibility of licensed facilitators leading guided sessions. These pilot programs are expected to model themselves after Oregon’s psilocybin services framework.
Anticipated Timeline
Advocates and lawmakers suggest that formal psilocybin retreat licensing could be considered within the next three to five years. Until then, California residents often look abroad for safe, legal options.
What Psilocybin Retreats Involve
While not yet legal in California, psilocybin retreats in legal settings worldwide typically include guided ceremonies, mindfulness practices, and community support. A retreat program often combines:
-
Preparation: Pre-retreat intake, health screening, and intention setting.
-
Ceremonies: Guided sessions using psilocybin mushrooms in safe environments.
-
Supportive Practices: Breathwork, yoga, meditation, and nature immersion.
-
Integration: Group talks and one-on-one sessions to process experiences.
These components are designed to give participants structure, safety, and reflection time.
Travel Options for California Residents
Many California residents who wish to attend psilocybin retreats currently travel to countries like Jamaica, the Netherlands, and Costa Rica. Each location has its own legal framework and retreat style. In Jamaica, psilocybin mushrooms are legal, and retreat centers operate openly with licensed facilitators.
We at ONE Retreats in Negril provide structured psilocybin-assisted retreat programs where participants can focus on growth, supported by preparation and integration sessions. This option has become popular with guests from California and other states who cannot yet attend such retreats at home.
Medical Research in California
California universities and institutions are active in psychedelic research. Studies at institutions such as UCSF and UCLA explore psilocybin’s role in treating depression, anxiety, and addiction. Research trials often focus on safety, dosage, and therapeutic protocols that may shape future retreat models within the state.
Preparing for a Retreat Experience
Even without retreats legally available in California, preparation remains important for those considering psilocybin experiences abroad. Preparation may include:
-
Practicing mindfulness or meditation
-
Engaging in breathwork and light exercise
-
Adjusting diet and sleep habits
-
Setting intentions with clarity and focus
These practices mirror the preparation phase many retreats already emphasize.
Key Considerations for the Future
-
Access: California is expected to eventually regulate psilocybin retreats, though not yet in 2025.
-
Travel: International retreats remain the main option for California residents.
-
Safety: Guided experiences with trained facilitators are recommended over unsupervised use.
-
Integration: Community and post-retreat support are essential parts of the process.
Final Thoughts
Psilocybin retreats in California are not yet legal in 2025, but the passage of SB 58 marks an important turning point. Decriminalization of personal use shows the state’s openness to broader reform. While licensed retreats will take time to develop, California remains central to psychedelic research and advocacy. For now, residents look to international retreats where legal frameworks allow safe and guided psilocybin experiences, while watching closely as California builds the foundations for future access.
