Electronic cigarettes look better, taste like a real cigarette but with no fire, no real smoke, no carcinogenic substances (40 carcinogenic substances are released during the burning of tobacco). No ashtrays, no cigarette butts (a way to go green) no stale smells, no air pollution. safe for people around you. no harmful effects from passive smoke. E cigarettes are free from the tar and harmful chemicals that real cigarettes contain. there is no second hand smoke. It only produces a safe vapor that is very close to our own body temperature. They taste like the standard marlboro or menthol but, there smoother and cleaner because they get rid of 4000 chemicals contained in real cigarettes. A single cartridge last to the equivalent of 8 to 10 conventional cigarettes. Do the math that is a lot of savings on your part. They work by a battery triggering the atomizer which turns the cartridge liquid into vapor. They really do create the same effect.
