Electronic cigarettes (e-cigarettes, ECs) are hand-held electronic atomization devices that generate mist by heating liquid e-liquid, and the components of e-liquid are generally nicotine and flavor. E-cigarettes allow nicotine to be inhaled into the body in the form of vapor, replacing the form of smoke. Certain harmful substances in tobacco can cause smokers to suffer from smoking-related diseases. Because e-cigarettes do not burn tobacco, users have lower levels of exposure to harmful substances than traditional smokers.
The English word used exclusively for electronic cigarettes is "vaping", which means vaping in the form of electronic cigarettes. Many people use e-cigarettes to help quit tobacco.
