Psychedelic 5-MeO-DMT infused in healthy brains: first safety data coming
NCT ID NCT07444788
First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time
Summary
This early-stage trial is testing how safe and tolerable intravenous 5-MeO-DMT is in 40 healthy adults aged 25-65. Participants receive either a low dose of the psychedelic or a placebo, and researchers monitor their subjective experiences, vital signs, and side effects. The goal is to gather basic safety and drug-effect data, not to treat any disease.
