Summary

This study tests whether inhaling high-THC cannabis can safely reduce PTSD symptoms in 320 veterans. Participants will either receive active cannabis or a placebo with almost no THC. The goal is to see if cannabis helps with PTSD severity and daily functioning, providing real-world evidence for a treatment many veterans already use.

What this could mean

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

Active substance: inhaled cannabis (high THC content)
What this could lead to: If it works, this could provide a new, controlled option for veterans to manage PTSD symptoms.
What could go wrong: This is a Phase 2 trial, so it is still early. The placebo effect is strong in PTSD studies, and cannabis may cause side effects like anxiety or impaired thinking.
