Vape refers to the act of inhaling vapor produced by electronic cigarettes (e-cigarettes) or similar devices, which heat a liquid (e-liquid or vape juice) to create an aerosol. Unlike traditional cigarettes, vaping doesn't involve burning tobacco but instead vaporizes a liquid typically containing nicotine, flavorings, and other chemicals . The term originates from the word "vapor" and was coined in the 1980s, later becoming Oxford Dictionary's 2014 Word of the Year .
