Something for people to whine about.

Candy cigarettes were my favorite growing up. Oddly enough, I despise cigarettes with a passion, and that's not a smart Passion. Can't stand them, that is the #1 reason we don't visit the in-laws - I get along great with them but my father-in-law is a serious chain smoker. (he lights his cigarette with the one he about to finish)
The kid's will smoke real cigarettes either way when the time comes. Someone telling them they can't will just make it worse. IMO
