While past marijuana opponents like John Boehner are coming around to legal weed, the Food and Drug Administration isn't likely to recommend that Americans light up a joint anytime soon.
That doesn't mean that cannabis will never be sanctioned by the FDA in some form, said Commissioner Scott Gottlieb. It's just highly doubtful that the agency would ever approve it for smoking.
"I prescribed blood pressure pills and all kinds of other things to my patients when I was a practicing physician not too long ago," Gottlieb said in an interview at Bloomberg's headquarters in New York. "I never told a patient to go home, crush up a pill, roll it in a piece of paper and smoke it."
