Dr. Gupta: 'Legalize Medical Marijuana'

CNN's Dr. Sanjay Gupta says medical marijuana should once and for all be finally legalized.
He says he knows how easy it is to do nothing, because he did nothing about it for too long. He says "I see a revolution in the attitudes of everyday Americans. For the first time a majority, 53%, favor its legalization, with 77% supporting it for medical purposes."
