How joining a trial works
- Free to take part
- Trials generally cost participants nothing for the study drug and the study visits, and some pay for travel or time. Check what a study covers on its registry page.
- Screened first
- Every study screens volunteers with questionnaires, medical history and often a physical and psychiatric check. Many people who apply are not enrolled.
- Eligibility is strict
- Common exclusions include a personal or family history of psychosis or bipolar disorder, some heart conditions, pregnancy and certain medications, which you may be asked to stop under medical supervision. Never stop a medication on your own to qualify.
- You may get a placebo
- Many trials compare psilocybin with a placebo or a low dose, and you may not be told which you had until the study ends.
- Contact the study team through the registry
- Each registry record lists the study contacts and sites. We do not republish personal emails or phone numbers; use the link on each trial page.
- Not medical advice
- This is a list of registry records, not a recommendation. Talk to your doctor before applying. Disclaimer · Safety and medications
