About

An electronic cigarette is a battery-operated device that emits doses of vaporized nicotine, or non-nicotine solutions, for the user to inhale. It aims to provide a similar sensation to inhaling tobacco smoke, without the smoke.

Also known as e-cigarettes, e-cigs, electronic nicotine delivery systems, vaporizer cigarettes, and vape pens, they are marketed as a way to stop or cut down on smoking.
