When I use a word . . . Terminology of hallucinogenic agents
BMJ March 27, 2026 J K Aronson
Various terms have been coined to classify hallucinogenic drugs based on their effects and mechanisms. "Psychedelics" act as agonists at serotonin 5-HT2A receptors and include psilocybin, mescaline, and LSD. "Entactogens" increase serotonin release and include MDMA and cathinones. "Oneirogens" induce dream-like states and include ibogaine. "Entheogens" are used in religious rituals and include peyote. Despite these classifications, the pathophysiology of schizophrenia remains poorly understood.
