E-cigarettes are devices that typically deliver nicotine, flavorings, and other additives to users through an inhaled aerosol. The use of e-cigarettes among youth is an exploding trend — from 2011 to 2015, vaping rose by over 900% among high school students, according to a report issued by the Surgeon General. It remains by far the most common form of nicotine use among young people.
These devices are referred to by a variety of names, including “juuls” e-cigs,” “e-hookahs,” “mods,” “vape pens,” “vapes,” and “tank systems.” E-cigarettes can also be used to deliver other drugs besides nicotine, such as marijuana.
Scientists are still learning more about how e-cigarettes affect health. However, there is already enough evidence to justify efforts to prevent e-cigarette use by young people. We know that the vapor from e-cigarettes is harmful because it contains harmful chemicals, in addition to nicotine. Nicotine exposure during adolescence can cause addiction and can harm the developing brain.
