All of $SPLI E-cigarettes are made up of a long-life battery, a heating element, a cartridge filled with an “e-liquid” which may or may not contain nicotine, and an atomizer, which when heated, vaporizes the e-liquid. Because our E-cigarettes are not “lit” like regular cigarettes, they don’t create flame, smoke from burning, ash, tar, noxious fumes or leftover “cigarette butts”. Also, they don’t produce a vapor containing poisonous carbon monoxide, so they are safer to “smoke”, and there is no “second-hand smoke” to concern those around you. http://www.vaporgroup.com/about-us/
