The Benefits: Vapor doesn’t smell bad like smoke, neither it discolors your teeth or makes your breath smell bad. In fact, vapor usually smells good like candy or vanilla, depending on the e-liquid. So, with e-cigs, you don’t have to slip out of a gathering, your office, or even your own living room to smoke. Vaping is obviously more socially accepted, but before vaping in public places, make sure you know the local laws as several states don’t allow it.
