CES: Even the E-Cigarettes Go Green

he idea of environmentally friendly technology is a common theme at CES, but Krave takes it to a new level with its so-called electronic cigarettes.Promising a “greener environment for both you and the non-smoking community,” Krave’s e-cigarettes are tobacco-free and instead contain a battery-powered nicotine cartridge in the white part of the cigarette. When a smoker inhales, a sensor inside the cigarette is activated, and the cartridge releases water vapor that looks like smoke but is mainly nicotine, water and a little of the food additive propylene glycol.
“There is no longer a need for anyone to breathe the unwanted, dangerous, second-hand smoke produced by traditional tobacco cigarettes,” Krave’s Web site says. 
rave’s parent company, Smoke Fifty-One, warns that its cigarettes are “not a smoking cessation product.” A starter kit containing one battery and four nicotine cartridges costs $30, though Smoke Fifty-One says that one cartridge will “last you through your evening.”
