After a decade of waging a hard-fought battle with the U.S. Drug Enforcement Agency, which repeatedly denied his application for the production of medical marijuana, Dr. Lyle E. Craker, a professor at the University of Massachusetts, said he would call it quits, resigning his fight in bitter defeat. The ACLU released its final brief on Craker's case, which calls on the DEA to grant research permits for the production of medical cannabis. They flatly state that cannabis medicines have not yet cleared the Food and Drug Administration because of the DEA's pernicious politics and tight monopoly on the granting of production licenses.
