DEA dismissed its own misconceptions about pot, group says

By Bob Egelko for the San Francisco Chronicle

Defending the government’s classification of marijuana as one of the most dangerous drugs, the U.S. Drug Enforcement Administration declares on its website that pot causes mental illness and lung cancer and leads youths to heroin and cocaine.
But an advocacy group says the DEA, in a legal filing in August, said it found no evidence to support any of those conclusions. The group, Americans for Safe Access, has asked the agency to remove discredited claims from its Web page.
