I gave up smoking 6 years ago and started chewing nicotine gum, Managed to give that up too but then started having odd sneaky fag, so went back to gum. Can't remember when but at least 3 years ago. I am now totally addicted to it, Does anybody know what the long term effects are and if it is really bad for you? At least its not as bad as fags but \i think \i ought to stop it.
