device usually used to quit or be an alternative to tobacco
An electronic cigarette is a battery-powered device that heats and vaporizes liquid (usually containing nicotine) for the user to inhale, designed as a way to quit smoking or use instead of traditional tobacco cigarettes. It matters because many people use it as a potential alternative to conventional smoking, though its long-term health effects and effectiveness as a smoking cessation tool remain subjects of ongoing research and debate.

It consists of an atomizer, a power source such as a battery, and a container such as a cartridge or tank. Instead of smoke, the user inhales vapor, often called "vaping".
The atomizer is a heating element that vaporizes a liquid solution called e-liquid that cools into an aerosol of tiny droplets, vapor and air. The vapor mainly comprises propylene glycol or glycerin, usually with nicotine and flavoring. Its exact composition varies, and depends on matters such as user behavior. E-cigarettes are activated by taking a puff or pressing a button. Some look like traditional cigarettes, and most kinds are reusable.
