Therapeutic psychedelic research is advancing steadily, with psilocybin, MDMA, and lysergic acid diethylamide designated breakthrough therapies by the US Food and Drug Administration (FDA). However, in August 2024, the FDA declined to approve a New Drug Application for MDMA and asked its sponsor to conduct another phase 3 trial. Clinicians are urged to prepare for the possible return of psychedelics to medicine.
