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.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance
5-MeO-DMT (a psychedelic compound)
What this could lead to
If successful, this study could help establish safe dosing guidelines for 5-MeO-DMT in future therapeutic research.
What could go wrong
This is an early Phase 1 safety study in healthy volunteers, not a treatment trial. The drug may cause unpleasant psychological or physical effects, and results may not translate to patient populations.
