San Francisco bans wildly popular cigarette alternative Unlisted Video

San Francisco officials voted on Tuesday to effectively ban the sale of e-cigarettes. It's the first US city to do so, and has thrust the coastal tech hub into a fierce debate over the future of smoking. Local officials say the move is part of an effort to "curb the epidemic of youth vaping," Advocates of the ban say the city must act where federal regulators have not, protecting teens and prohibiting the sale of untested products until they undergo FDA review.
