Listen, dumbhead. How in the hell can this be insane and stupid? First of all, the harmful ingredients that are produced when all sorts of stuff in a cig is burnt are what causes cancer. Hello? WTF?! Nicotine in and of itself is not necessarily bad at all for your system, and it is actually used medically for different purposes (look it up, bozo). Further, you can get cartridges that have ultra-light nicotine content. I speak from experience. I use my e-cig all the time. And I love it. It is not EXACTLY the same as smoke, but I am growing to like it more. AND: I am not ruining my lungs in the process. It's dumbasses like you that 1. sound like you have a contract for PR with JR Reynolds, and 2. Ruin an amazing idea for the late adopters. Pull your head out, do some actual research, and then write an article, idiot.
