NIDA's Federal Medical Cannabis Program
"It is a judicial fluke that the National Institute on Drug Abuse has provided medical marijuana to a handful of patients (never more than 32, currently 4 surviving) as the outcome of the settlement in a lawsuit pressed in 1976 by a man with cannabis-responsive glaucoma. That settlement became the basis for the FDA’s Compassionate Investigational New Drug Study program for patients with marijuana responsive conditions. No patient has been enrolled since 1992, when the George H. W. Bush administration suspended new registration in reaction to a large influx of applications from AIDS patients."
