We don't 100 percent know if it's safe. Studies to determine the potential health and safety issues long-term need time; vaping is so new that this time hasn't elapsed yet. But the fact that you're not burning tobacco and breathing in the smoke "feels" like it should be healthier, right? In fact, Mitch Zeller, director of the United States Food and Drug Administration's Center for Tobacco Products said in mid-May 2014, "If we could get all of those people [who smoke] to completely switch all of their cigarettes to non-combustible cigarettes, it would be good for public health." That's something right? That aside, the only other recent blessing comes from a very recent study on its ability to be used as a tool to quit smoking. It appears that the University College London's 6,000 person, seven-year research shows it is much more successful than other nicotine replacement tools or cold turkey.
