OK, so how does an E-Cigarette work?
An E-Cigarette is a cigarette-sized tube with a colored LED light on the end, containing a battery and an atomizer cartridge that holds liquid. When the user draws in, a pressure-activated switch turns on a mini heating element and produces a vapor that looks like smoke.
This vapor is essentially the same smoke commonly seen in nightclubs, concerts and theatres in fog generators when used for special effects. The vapor can also contain nicotine in doses regulated by the user, and a variety of flavors: among them chocolate, mint, tobacco, apple, and many others. Users can even get the flavor of their favorite brand of cigarettes.
