DEA chief: medical marijuana is "a joke." Science: No, it's not.

Chuck Rosenberg, head of the Drug Enforcement Administration, is either woefully ignorant, protective of his administration's reckless mission, or both. "What really bothers me is the notion that marijuana is also medicinal because it's not," Rosenberg said in a briefing. "We can have an intellectually honest debate about whether we should legalize something that is bad and dangerous, but don't call it medicine that is a joke."

The American Medical Association begs to differ. From Vox:

The best study done to date, published in the Journal of the American Medical Association, reviewed the research and concluded that pot again, including its smoked form can effectively treat chronic pain and muscle spasticity. The study didn't rule out other potential medicinal benefits, but those were the two it found the best evidence for.
