CNN’s Gupta: I was wrong about marijuana

NEW YORK – CNN’s Dr. Sanjay Gupta says he spoke too soon in opposing the medical use of marijuana in the past and that he now believes the drug can have very real benefits for people with specific health problems. Gupta, the network’s chief medical correspondent and brain surgeon, detailed his change of heart in an interview for CNN’s website titled, “Why I changed my mind on weed.” He will narrate a documentary on the topic that will air on the network Sunday.
