Like NIC15, I've been chewing for much longer than I should have been...I've quit a few times and eventually for some reason have gone back to it. DON'T START!
If you really feel like you want to because others are, that is the WRONG reason...
Outside of never starting, my best recommendation would be for you to chew gum...
They do make dip that does not contain tobacco or nicotine, but that doesn't mean it is good for you either...be smart and don't start...
A Dad who's son constantly reminds him he needs to quit...
