Psychedelic Retreats Offer Mental Health Breakthrough for Military Veterans

LOS ANGELES- A growing body of evidence is challenging how we treat combat-related trauma—and this time, it’s not coming from a VA clinic, but from jungle retreats in Peru and quiet mushroom ceremonies in Jamaica.

A new peer-reviewed study suggests that psychedelic-assisted retreats may offer powerful short-term relief for veterans suffering from PTSD, depression, anxiety, and sleep disorders. Conducted by an international team of researchers in partnership with the nonprofit Heroic Hearts Project, the study tracked 58 veterans through immersive retreats involving either psilocybin or ayahuasca. Four weeks after returning home, participants showed marked improvements across every mental health category, including a 29% reduction in depression and a 26% drop in PTSD symptoms.

While the results aren’t yet conclusive—this was an observational study, not a clinical trial—they add fuel to a rapidly growing movement that views psychedelics not as recreational drugs, but as tools for deep healing. For many of the veterans involved, traditional treatments had fallen short. These retreats, which combine psychedelic ceremonies with integration coaching and peer support, provided something different: a path forward.

Interestingly, the data also revealed nuanced effects between substances. Psilocybin retreats appeared more effective in reducing depression and anxiety, while ayahuasca retreats slightly outperformed in lowering PTSD symptoms. Gender differences also emerged—men reported broader improvements overall, but women in the study experienced more dramatic relief from PTSD.

It’s important to note the caveats. There was no control group, results were self-reported, and follow-up stopped at the one-month mark. Still, for a population that often struggles in silence—and in systems that rarely evolve—these findings offer a potential new frontier in trauma treatment.

HCN will be watching this space closely as more organizations step up to bridge the gap between psychedelic science and veteran care. For now, it’s clear: healing doesn’t always look like a prescription pad. Sometimes, it looks like a circle of veterans, a cup of tea, and the courage to sit with the unknown.
