Summary

The first U.S. pilot in severe treatment-resistant military PTSD reported no serious adverse events and substantial short-term remission.

Ohio State researchers enrolled 12 veterans with severe, treatment-resistant PTSD in a psilocybin-assisted therapy pilot. The team reported no serious adverse events or increase in suicidality, and nine participants met remission criteria one month after treatment. With no control group and a very small sample, the study establishes feasibility and a signal for larger trials, not treatment efficacy for the broader veteran population.
