One understudied condition for which small doses of psychedelic substances such as psilocybin may be beneficial is cluster headache.
As founder and executive director of the advocacy group Clusterbusters, I have seen firsthand, as a patient and an activist, that, despite its modest name, cluster is far from “just” a headache. It is a chronic pain condition that lasts “on” and “off” for months or years, often with no hint as to its origin. Estimates suggest that one in 1,000 people – which equates to over 332,000 Americans – suffer from cluster headache.
