A researcher at the University of Arizona is a step closer to studying how medical marijuana affects veterans with post-traumatic stress disorder, according to USA TODAY.
Although there is a "mountain of anecdotal evidence" that marijuana helps with PTSD, there has been no controlled trial to test how marijuana suppresses the symptoms, including flashbacks, insomnia and anxiety, said Suzanne Sisley, the study's lead researcher.
Sisley's study proposal has wound its way through the federal government for three years. In 2011, she received approval by the Food and Drug Administration. On Friday, the study cleared a major hurdle when the Public Health Service, part of the U.S. Department of Health & Human Services, gave its approval, USA TODAY reports.
