Among other studies already underway,

 Colorado just approved over $8,000,000 to study the medicinal effcts of cannabis. The studies, most of which will be overseen by researchers from various universities, will explore marijuana's efficacy when used to treat post-traumatic stress disorder, Parkinson's disease, pediatric epilepsy and brain tumors, and will compare the plant's painkilling qualities with those of prescription opioids. Although the clear majority of Americans favor the legalization of pot, the righwingnuts in Nebr and Okla (where 'fines' for 'Colo bought' pot possession are a HUGE new source of revenue) have filed suit against the state of Colorado, where 'the people spoke, with their votes' and now pot is legal, here, after it has been used medicinally, worldwide for centuries, UNTIL the 'conservatives' took over, under Tricky Dicky Nixon, to punish the 'anti-Viet Nam' hippies. Just another Repub example of 'who cares what the people/voters want'. the rightwingnuts are pushing their agenda. You ever notice how Pubs are all for 'states rights' until they disagee with them? Same old crap....
