Psychedelic drugs that activate the 5-HT2A receptor, such as psilocybin and DMT, produce dose-related psychological effects including hallucinations, out-of-body experiences, emotional breakthroughs, and mystical-type experiences. When combined with psychological support, these substances can rapidly improve mood in people with depression, with benefits lasting months. The therapeutic effects may stem from increased brain entropy that disrupts fixed negative thinking, enhanced cognitive flexibility after treatment, and changes in self-referential psychological processes. The brain mechanisms underlying serotonergic psychedelics likely differ from those of classical serotonin reuptake-blocking antidepressants.
