Electronic Cigarette Use Among Youth and Adolescents

Electronic nicotine delivery systems (ENDS) heat a liquid to create an aerosol that is inhaled by the user. The liquid contains nicotine and other toxic chemicals. Although ENDS do not contain tobacco, they are still considered tobacco products because nicotine is derived from tobacco. The most common ENDS are electronic cigarettes (e-cigarettes) and vape pens.
Electronic non-nicotine delivery systems (ENNDS) are another type of e-cigarette similar to ENDS but they do not contain nicotine. E-cigarettes claiming to be nicotine-free still typically contain trace amounts of nicotine.1 Although ENDS and ENNDS may not contain tobacco, harmful long-term health implications remain prevalent.
