Campbellking, I think you're missing the point with regard to what fairkatrina was saying about obesity. Yes, people who smoke are often obese as are people who don't smoke, yet there are many people who smoke now who are not at all overweight. On quitting smoking, it is a common occurence that people replace smoking with eating, as their sense of taste heightens, their appetite increases, their metabolism drops (only slightly but enough to make a difference if they don't watch their intake) and above all they need something else to do! Therefore, quitting the fags can be the start of a long road to obesity. My best friend stopped smoking and put on 3 stone in 6 months. She eventually started smoking again, not because of her weight gain but because of her addiction (she had one on a night out.....) So now she is a fatty and a smoker and the situation is twice as bad!
