Cannabis for Symptoms of PTSD in U.S. Veterans

MAPS has received regulatory approval to conduct a study of smoked cannabis for symptoms of PTSD in veterans of war. The study evaluated safety and efficacy of four different potencies of cannabis.

The WeCan Study is an effort of MAPS to collect information about the efficacy of cannabis-based treatments for PTSD.

The WeCan Study is a Phase 2 clinical trial to test safety and efficacy of four different concentrations of cannabis in people with PTSD. This study explores whether smoked cannabis can help reduce PTSD symptoms in U.S. veterans with chronic, treatment-resistant PTSD.
