E-cigarettes, also known as e-cigs or vape pens, are battery-powered devices that give the user the sensation of smoking a cigarette, but electronically. The e-cigarette works by heating the e-liquid inside into aerosol. Once the evaporated liquid has melded with the air the user can inhale and exhale.
E-cigarettes come in many different shapes and sizes as well as a wide range of flavors including mint, peach, classic tobacco, cucumber, crème brulee, and menthol. E-cigarettes have become increasingly popular as many see them as an alternative to smoking traditional cigarettes. Popular brands include Halo, Juul, Mojo, XPOD, Vuse, and V2.
