This course provides a concise survey of research on psychedelics and psychedelic-assisted therapy, beginning with early LSD studies in the 1950s and 1960s and the later halt in psychedelic research in the early 1970s. It also explains how interest in the field has increased over the last decade through new clinical trials and emerging applications in mental health treatment. The content covers MDMA-assisted therapy for PTSD, psilocybin-assisted therapy for depression and end-of-life distress, and ketamine’s role in depression treatment. It also references trial phases, breakthrough therapy status, and examples of outcomes reported in the source text. This material is intended for learners seeking a research-based overview of psychedelic medicine, including students, clinicians, and others interested in the evidence base behind current and emerging treatments. The source does not specify a detailed course format, duration, or assessment structure.
