How It Works
An e-cigarette is a battery-powered device that converts liquid nicotine into a mist, or vapor, that the user inhales. There’s no fire, no ash and no smoky smell. E-cigarettes do not contain all of the harmful chemicals associated with smoking tobacco cigarettes, such as carbon dioxide and tar.
Manufacturers and satisfied customers say the e-cigarette is a healthier alternative to tobacco cigarettes, which cause millions of deaths every year. Some users say e-cigs have helped reduce their “smoker’s cough,” sharpened their senses of taste and smell, and even improved their sleep.
