They are electronic, safer smoking alternative devices that simulate the sensation of smoking without the worry of taking in cancer causing agents and other harmful chemicals that are normally associated with traditional tobacco products. They produce simulated smoke that is actually a vapor mist that looks, tastes, feels and reacts very similar to actual tobacco smoke. When exhaled, the vapor harmlessly evaporates in the surrounding air within a few seconds. They do not use tobacco at all. In fact, the nicotine that is used is synthetic and derived from other natural sources other than tobacco. The basic components for the Elite and Prestige consist of a battery, an atomizer, a safe, flavored cartridge that is filled with Propylene Glycol and varying degrees of nicotine and a computer chip that controls it all. Both the atomizer and cartridges are considered to be consumables. Cartridges are available in varying degrees of nicotine that include high, medium, low and no nicotine at all. The Elite is a longer, more elegant design while the Prestige features a sleeker, smaller design.
