An independent guide

The law in each place, and who can be trusted.

Ayahuasca, psilocybin, iboga and San Pedro: what the law says in each place, stated honestly, including where the medicine is illegal; the screening that keeps people safe; and the research worth reading. Written for people making a real decision, not browsing.

Our position

We don't list peyote ceremonies.

Peyote is a slow-growing cactus that the IUCN Red List assesses as Vulnerable, and it is the sacrament of the Native American Church. In 2020 the National Council of Native American Churches and the Indigenous Peyote Conservation Initiative asked that decriminalisation efforts leave peyote out.

Colorado drew the same line in statute. Its natural medicine law says that “mescaline” does not include peyote, Lophophora williamsii, after Indigenous community members asked for that exclusion.

So we point that demand to cultivated San Pedro, never wild plants. It carries the same primary alkaloid. Every figure behind this position is sourced on the position page.

The law in each place

All 133 centres

133 centres across 9 jurisdictions. Each place carries its legal footing for the medicine served there: lawful, state-licensed, unregulated, tolerated though not authorised, or illegal but tolerated in practice, where the law prohibits it but retreats operate openly and we found no reported prosecution. A listing isn't an endorsement, so every profile says plainly what we have and haven't checked, and shows any public record.

Without a psychedelic

For everyone the screening rules out

All 15 practices

A psychosis history, a cardiac condition, an SSRI prescription, or no money this year. Plenty of people arrive here and find the answer is no. 15 practices and 43 named centres that reach comparable territory without a controlled substance, and some of them are harder than anything in the directory above.
