What are E-cigarettes?

E-cigarettes, including, e-pens, e-pipes, e-hookah and e-cigars, are known collectively as electronic nicotine delivery systems (ENDS). According tothe FDA, e-cigarettes are devices that allow users to inhale an aerosol (vapor) containing nicotine or other substances. Unlike traditional cigarettes, e-cigarettes generally are battery-operated and use a heating element to heat e-liquid from a refillable cartridge, releasing a chemical-filled aerosol.

What’s in E-cigarettes?

The main component of e-cigarettes is the e-liquid contained in cartridges. To create an e-liquid, nicotine is extracted from tobacco and mixed with a base (usually propylene glycol), and may also include flavorings, colorings and other chemicals. Unlike traditional cigarettes, e-cigarettes are loaded with a vaporizable liquid. This fluid is made up of a number of chemicals, among them propylene glycol, glycerol, nicotine and variety of flavoring substances. While these chemicals don’t sound entirely appealing, the new research shows that the real danger may be in how these compounds change when heated.
