Is It Safer To Vape Than Smoke?

Ten years ago it was unusual to see a billowing cloud of nicotine vapor flowing out of a car window while the driver puffed on an e-cigarette. In fact, you were probably startled the first time you saw it, but now it's so commonplace that it barely registers a second glance. E-cigarette shops, or vape shops, are popping up all over cities across the country, providing their customers with a different way, and some say a safer way, to get their nicotine fix.
