For those unfamiliar, an electronic cigarette or e-cigarette is a handheld electronic device that creates an aerosol by heating a liquid. The user then inhales the aerosol. Using e-cigarettes is sometimes called vaping. The liquid in the e-cigarette, called e-liquid, is usually made of nicotine, propylene glycol, glycerine, and flavorings.
