Psychedelic therapeutics in psychiatric conditions
Neuropsychopharmacology January 16, 2026 Philip D. Harvey, Charles B. Nemeroff 2 citations
Interest in psychedelic therapies is booming, yet no psychedelic treatment has been approved for any psychiatric condition. The one large-scale MDMA development program that reached the FDA was disapproved for reasons that could also apply to classical psychedelic trials. This review defines psychedelics, surveys current therapies, targeted conditions, compounds under investigation, and research strategies. Some interventions combine drugs with psychotherapy, bringing both benefits and challenges. Debate continues over whether the psychedelic experience itself is essential for therapeutic effect, complicating blinded trials. The review also addresses societal issues like deregulation of formerly illegal substances and regulatory hurdles, including alternatives to blinded trials and whether targets like adjustment disorder pose problems under current standards.
