From Wikipedia, the free encyclopedia

An electronic cigarette is an electronic device that simulates tobacco smoking. Electronic cigarettes, also known as e-cigarette among other names,[notes 1] are handheld battery-powered vaporizers rather than combustible tobacco products.[1][2] Using an e-cigarette is called "vaping".[3] Instead of cigarette smoke, the user inhales an aerosol, commonly called vapor.[4] E-cigarettes typically have a heating element that atomizes a liquid solution called e-liquid.[5] They are activated by taking a puff or pressing a button.[6][3] Some look like traditional cigarettes,[7] but they come in many variations.[3] Most versions are reusable.[8]

The benefits and risks of e-cigarettes are uncertain.[9][10][11] They are likely safer than smoking tobacco,[12][13] with NHS England estimating them to be around 95% less harmful.[14] There is tentative evidence that they can help people who smoke quit.[12][13][15] Young people who use them are more likely to start smoking.[16][17]

E-cigarettes create vapor made of fine and ultrafine particles of particulate matter,[18] which contain propylene glycol and/or glycerin, usually nicotine and flavors, and small amounts of toxicants,[18] carcinogens,[19] heavy metals, metal nanoparticles, and other substances.[18] Its exact composition varies, and depends on several factors including user behaviour.[notes 2]

Nicotine is toxic and highly addictive.[20] Young people are particularly susceptible to this, and most (90%) smokers start before the age of 18.[21] Among first-time users 32% of people who try nicotine become addicted.[20]
