- [How to compare psilocybin centers](https://psilocybincenters.fyi/guides/how-to-compare-psilocybin-centers.md): Compare licensed centers by state program, licence type, services, and published session price. Verify each licence with the state agency before you decide.
- [What a psilocybin center listing shows](https://psilocybincenters.fyi/guides/what-a-listing-shows.md): Every listing is a public licence record from a state registry. Read the licence type, services, session price, accessibility and source note, then verify the licence.

> **Not medical or legal advice.** Psilocybin Centers lists facilities that hold a licence from a US state program, such as the Oregon Health Authority or the Colorado Natural Medicine Division. Psilocybin is still illegal under United States federal law, and its legal status differs by state and by city. A listing is a public licence record, not an endorsement. Nothing on this site is medical or legal advice, and no listing makes claims about health outcomes. Verify the licence and the rules with the state agency named on each listing before you decide.
