Psychedelics and Headache Disorders: an Update.

PURPOSE OF REVIEW: Psychedelics are often queried as a potential therapeutic option in a multitude of conditions, including pain and mental health disorders, with a growing body of patient reports and scientific publications describing potential benefit. This article reviews recent research on psychedelic compounds for treatment of headache disorders.

RECENT FINDINGS: Observational data, case reports, and a few recent small, controlled trials suggest symptom benefit at sub-hallucinogenic doses for both migraine and cluster headache. There have not been new completed studies of psychedelics in other headache disorders. Safety signals also tend to be favorable, although there are continuing concerns for systemic and psychiatric effects in varying doses, preparations and clinical contexts. While available studies on psychedelics suggest potential benefit in cluster headache and migraine, access remains complex due to legal considerations, and additional studies are needed to confirm their effectiveness and to ensure safety before they can be recommended for use.
