Psychedelics targeting 5-HT₂A receptors show promise in modulating fear circuits, but their specific neurobiological substrates remain unclear. This study investigates the effects of 4-acetoxy-N,N-dimethyltryptamine (4-AcO-DMT), a psychedelic compound, on innate fear responses and...

Microdosing is the practice of taking a very small, sub-perceptual dose, typically 5% to 10% of a full recreational dose, to improve mood, creativity, and focus without...
An individualized one‐day dosing regimen of a vaporized formulation of the psychedelic mebufotenin (5‐methoxy‐ N,N ‐dimethyltryptamine; 5‐MeO‐DMT) was more effective than placebo in improving depressive symptoms in adults with treatment‐resistant depression, a Phase 2b trial has found. No serious treatment‐emergent adverse events were reported during the 7‐day study. Results were published...
