What are e-cigarettes?
E-cigarettes, or electronic cigarettes, are devices that allow users to mimic the act of smoking cigarettes while inhaling nicotine. Instead of smoke from burning tobacco, users inhale vapor consisting of nicotine, flavor additives and other chemicals. When users inhale from the end of an e-cigarette, a battery-operated device heats a liquid solution into a vapor.
Smokeless does not mean harmless
Preliminary testing of e-cigarettes has identified chemicals known to cause cancer and birth defects in first and secondhand e-cigarette vapor. However, e-cigarettes remain under-studied and unregulated.
The FDA has analyzed samples of e-cigarettes finding known carcinogens and detectable levels of other toxic chemicals. The Center for Tobacco Control Research and Education at University of California San Francisco analyzed recent studies and concluded Benzene, Cadmium, Isoprene, Lead, Nickel, Formaldehyde, Acetaldehyde, and Toluene are present in many brands of e-cigarettes.
