Medical marijuana is currently legal in 25 states and the District of Columbia, with additional states voting on its legality come Election Day. Despite its growing acceptance, and the August announcement by the Drug Enforcement Administration that it would allow increased research on medical uses for it, the drug is still classed on the DEA’s Schedule 1 “most dangerous” list.

The report said that the VA doesn’t permit medical marijuana as a treatment for PTSD or other conditions because of a dearth of studies on the effectiveness of medical pot in easing PTSD. But that hasn’t stopped a number of veterans from seeking it out rather than using prescription antidepressants or painkillers. In addition, some states specifically list PTSD as a condition for which doctors can recommend cannabis.

Despite the failure of the measure to pass, its supporters plan to continue to press for the acceptance of medical marijuana as a treatment for veterans.

In a statement, Blumenauer said, “It’s incredibly frustrating and disappointing that despite broad bipartisan, bicameral support, a handful of out-of-touch lawmakers put politics over the well-being of America’s wounded warriors. Our veterans deserve better.” He added, “We will continue to seek every opportunity to make sure they have fair and equal treatment and the ability to consult with, and seek a recommendation from, their personal VA physician about medical marijuana.”
