That's interesting. It's been known for a while that Nicotine can cause Cancer...but I don't know if they had boiled it down so specifically. It does make one wonder. If they can find a way to remove that specific molecule, but keep the rest of it intact, if smoking or chewing Nicotine could relatively be made to be safe (well at least as safe as putting anything on fire to your mouth if you smoke)...or at least not be seen as a cause (or more accurately I suppose, a gateopener for) cancer.
