DETROIT (Michigan News Source) — Amid growing claims about cannabis and mental health, Wayne State University is moving the conversation out of anecdote and into controlled clinical trials.

The university is recruiting military veterans with post-traumatic stress disorder to participate in a new, federally approved research effort examining whether cannabis can safely and effectively treat PTSD and reduce suicide risk.

The project, known as “Warrior C.A.R.E.,” includes two distinct 12-week studies: one focused on cannabis as a standalone treatment and the other assessing cannabis in combination with therapeutic care. Researchers will evaluate how differing THC and CBD concentrations affect mental health outcomes, including mood stability and overall quality of life.

“This study represents a critical step in addressing the mental health challenges facing veterans,” lead investigator Dr. Leslie Lundahl said, who emphasized the need for data rather than assumptions.

The research is backed by $30 million in grants from the Michigan Cannabis Regulatory Agency, funded through the voter-approved Marijuana Regulation and Taxation of Marijuana Act. That law set aside $40 million statewide for FDA-approved studies focused on veterans’ health and suicide prevention.

Recruitment is now open. Eligible participants must be veterans ages 19 to 69 who have had PTSD symptoms and used cannabis within the past year.
