Electronic cigarettes are battery-powered vaporizers that simulate the feeling of smoking, but without tobacco. Their use is commonly called "vaping". Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor, typically released by a heating element that atomizes a liquid solution known as e-liquid. The user activates the e-cigarette by taking a puff or pressing a button. Some look like traditional cigarettes, but they come in many variations. Most are reusable but there are also disposable versions called first-generation cigalikes; there are also second, third, and fourth-generation devices. E-liquids usually contain propylene glycol, glycerin, nicotine, and flavorings. Some e-liquids contain ingredients such as cannabis, tobacco extract, or other additives.
