The Federal Drug Administration have classified this plant as a "Schedule 1" drug, the same as PCP, Cocaine, Heroin and other famous substances.
While it is classified as such, research opportunities are extremely limited, and not applicable to Federal guidelines.
States with an MMJ program can and do perform studies, but they are at odds with the Federal regulations.

"Our hands are tied" remains a valid argument, and they're still able to capitalize on the addictive nature of their existing 'therapies'.
