My husband and I have never smoked, in our entire lives. (I’m 46, he’s 50.) Our parents were smokers (his still are) and we thought it was gross.
Our 21-year-old daughter smokes. Apparently just about every enlisted person in the Coast Guard smokes. She’s an adult ... just don’t smoke in our house. Fortunately, our 18-year-old son is a musician, and he says smoking and excessive drinking would damage his voice, and he can’t have that.
