Contraindications

When this work is not safe.

Psilocybin is not safe for everyone. The factors below may mean a retreat is not appropriate for you. This page is a reference, not a diagnosis, and is to be verified by our medical advisor.

Suitability is always decided through a personal screening conversation, never by a form. If any of these apply to you, tell us during screening so we can make a safe decision together. Do not stop any prescribed medication on your own. This page is not medical advice; consult your physician.

This list is to be reviewed and finalized by the medical advisor before publication. For how screening works, see Safety & Screening.
