An Electronic Cigarette is simply a nicotine delivery system that uses vapor or steam to deliver the nicotine rather than harmful carcinogens like regular cigarettes. Electronic cigarettes are a healthier alternative to traditional smoking. You smoke the electronic cigarette pretty much just like a traditional one; except there is no need to suck in the thousands of chemicals and carcinogens that you get from a traditional cigarette. After all did you know it's not really the nicotine that is so bad for you â but the literally thousands of horrific byproducts that come along with cigarettes.
