Last week, Dr. Sanjay Gupta announced a drastic shift in his perspective on pot, a hugely promising sign that marijuana is increasingly gaining mainstream acceptance. In an op-ed published Thursday, "Why I Changed My Mind on Weed," CNN's chief medical correspondent Dr. Sanjay Gupta explained why he now supports medical marijuana. "It doesn't have a high potential for abuse, and there are very legitimate medical applications," Gupta wrote. "In fact, sometimes marijuana is the only thing that works."
Dr. Gupta said that he came to this conclusion from working on "WEED: A Dr. Sanjay Gupta Special." In the documentary, which aired Sunday, Dr. Gupta travels around the world to uncover "the highs and lows of cannabis." Watch the video, posted to YouTube, below:
