E-Liquid
An electronic cigarette (e-cig or e-cigarette), personal vaporizer (PV) or electronic nicotine delivery system (ENDS) is a battery-powered vaporizer which simulates the feeling of smoking, but without tobacco combustion.[1] Their use is commonly called "vaping".[2] The user automatically activates the e-cigarette by taking a puff;[3] other devices turn on by pressing a button manually.[4] They are often cylindrical, but come in many variations.[5] Some e-cigarettes look like traditional cigarettes, but others do not.[6] There are disposable cigalikes which are known as first generation "cigalikes" and there are reusable versions.[7] Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor.[8] E-cigarettes typically have a heating element that atomizes a liquid solution known as e-liquid.[9] E-liquids usually contain propylene glycol, glycerin, water, nicotine, and flavorings.[10] E-liquids are also sold without propylene glycol, without nicotine, or without flavors.[11][12][13]
