Exploded View of the E-Cigs Electronic Cigarette

Your electronic cigarette employs the latest smart technology to provide you consistent and long-lasting operation. When you inhale through the device, air flow is detected by the smart chip controller which activates a heating element that vaporizes the nicotine solution stored in the mouthpiece. On the opposite end of your electronic cigarette the LED will light red indicating proper atomization.

E-Cigarettes Sold As Safe,

"E-cigarettes are often sold as safe, which is probably not true," Talbot added. "They may not be as dangerous as real cigarettes, but on the other hand, they could be. We just don't know."

Electronic cigarettes typically use a rechargeable battery-operated heating element to vaporize the nicotine in a replaceable cartridge. Nicotine is usually dissolved in propylene glycol, a clear and colorless liquid that is commonly found in inhalers, cough medicines and other products.

Some e-cigarettes are made to look like real cigarettes, cigars or pipes. Others look like pens or USB memory devices. There is no tobacco involved, and no smoke either. Instead, users do what's called "vaping." As they inhale, they take in nicotine-filled vapor.

By isolating nicotine, e-cigarettes should carry far fewer chemical risks than regular cigarettes, said Michael Siegel, a tobacco researcher at Boston University. Tobacco contains about 5,000 known chemicals, he said, with as many as 100,000 more that haven't yet been identified. E-cigarettes eliminate many of those ingredients.
