I'm thinking of a particular family I knew growing up who always had a smoke-filled home. From what I remember, nearly all of the children in that household ended up being smokers. It made me sad, but I always wondered if they'd developed a dependence on nicotine without ever smoking themselves. Granted, they would have had to choose to smoke their first cigarette, but perhaps something would have "clicked" after they smoked it. Does anyone have any experience growing up in a smoking household? Did it seem to foster or initiate nicotine dependence?
