You won't think about misplacing your lighter or perhaps your matches if you are smoking an e-cigarette

You might never be worried about losing your lighter or your matches if you're smoking an e-cigarette -- there's nothing to light. Instead, e-cigarettes utilize a lithium battery; each also includes a vaporization chamber plus a cartridge filled with liquid. Whenever you puff on your e-cig as you would a normal cigarette, the battery powers the device to heat the liquid and vaporize it. Some e-cigarettes contain a cigarette-like LED tip that glows red (or another color, with respect to the product you're using), but not all of these smokeless gadgets mimic regular cigarettes. Because they do not burn tobacco, there isn't any smoke, no carbon monoxide without any odor; most certainly what you really inhale is vapor [source: FDA].To supply informaition on computerized tobacco
