Please sign John Olver and Dana Rohrabacher's Congressional Sign-on letter to the Drug Enforcement Administration in support of Professor Lyle Craker's application for a Schedule I license to produce research-grade marijuana for FDA- and DEA-approved clinical studies at the University of Massachusetts. It is hypocritical for DEA on the one hand to cite insufficient research as a reason for keeping marijuana un-prescribable, while on the other hand preventing the very research that it says is needed from taking place. Professor Craker's proposal would end this catch-22 that the DEA has created, by allowing the controversy over medical marijuana's safety and efficacy to be settled through FDA-approved clinical trials.
