Study Summary

This trial is testing whether psilocybin, a compound found in some mushrooms, can help treat cluster headaches. People with cluster headaches will be given either a placebo or psilocybin in three sessions, separated by 5 days. They will keep a headache diary before, during, and after the sessions. After at least 6 months from the last session, they may be invited back for a second round of the trial.
