What happens if you smoke while chewing gum?

Lose flavor: You will lose the flavor of the gum. Also, greater risk for swallowing or inhaling the gum.

Nothing.: I do not know of any ill affects of doing the two together that are different from smoking alone. If you want to have a greater peace of mind while growing older, i strongly recommend you stop smoking. The links to cancer and heart disease are so well documented i feel that smokers are committing suicide slowly.
