to quit, from what I am told. My wife hasn't smoked a cigarette in 18 years, yet she tells me that she still has a craving for them every once in a while. I never smoked but used to do the "real" chew -- I still would like to buy a plug & chew for when I'm on the jobsite.
Take care of yourself & your wife...hope you get to feeling better.
