A big reason for the get-tough stance, say White House insiders, is that federal agencies like the Drug Enforcement Administration are staffed with hard-liners who have built their careers on going after pot. Michele Leonhart, a holdover from the Bush administration whom Obama has appointed to head the DEA, continues to maintain that pot is as dangerous as heroin – a position unsupported by either science or experience. When pressed on the point at a congressional hearing, Leonhart refused to concede any distinction between the two substances, lamely insisting that “all illegal drugs are bad.”
