Electronic Cigarettes. By www.NeuroSoup.com An electronic cigarette or "e-cigarette" is an alternative to smoked tobacco products, like cigarettes, cigars, or pipes. It is a battery-powered device that provides inhaled doses of nicotine by delivering a vaporized propylene glycol and nicotine solution. Electronic cigarettes are often designed to resemble the outward appearance of cigarettes and other real smoking products, like cigars or pipes. Another common design is the "pen-style", named because it looks like a ballpoint pen. When a user inhales through the device, air flow is detected by a sensor, which activates a heating element that vaporizes the nicotine solution that is stored in the mouthpiece. It is this vapor that is inhaled by the user. To help e-cigarettes look like real cigarettes, an LED light on the end of the device opposite the mouthpiece is activated during inhalation.
