The most important feature of e-cigarettes, however, is that they do not possess the same degree of health risks associated with real cigarettes. Using heat to vaporize a liquid contained inside the device, e-cigarettes are made to help people quit smoking.

An electronic cigarette, or e-cigarette, is an electrical device that simulates the act of tobacco smoking by producing an inhaled vapor bearing the physical sensation, appearance, and often the flavor (with or without nicotine content) of inhaled tobacco smoke, without its odor or, ostensibly, its health risks.
