A new RAND study reports that nearly 5 million U.S. veterans have used psychedelics and related drugs, including “magic mushrooms,” LSD, or MDMA. The findings draw attention to how many veterans report lifetime use of these substances and highlight gaps in veterans’ understanding of Veterans Affairs (VA) policies concerning psychedelics.

According to coverage of the study by multiple outlets, the research finds that many veterans are unclear about what the VA allows, covers, or prohibits regarding psychedelic use and treatment. The articles note that confusion about policy is a central theme of the report.

The sources describe the study as based on veteran responses and framed around their experiences and knowledge of VA guidance. While the articles focus on prevalence and confusion over policy, they do not present evidence in these reports about specific outcomes of use or broad implementation of psychedelic-related care within the VA. The reported key point across sources is the scale of reported use and the need for clearer information to veterans about VA policies.
