If it still has all the same ingredients I would imagine it would still cause cancer. However, if it is just nicotine, then probably not. In fact, while nicotine is a poison in large enough doses, it will actually help folks who have Parkinson’s a bit, at least in the early stages of the illness, by suppressing the symptoms. In fact, a spokesman for Reynolds says They are made from finely milled tobacco. This tells me that the same things that cause mouth cancer in chewing tobacco are still there to cause mouth, throat and possibly stomach cancer. All that is missing is the smoke and hence the effects on the lungs.
