I never have and never will smoke, I was pretty heavily conditioned against it as a child. That being said I have a fair amount of family members and friends that do smoke and it's rather interesting to see most people who are smokers really don't want to be smokers, it just becomes too hard for them to quit. Do I think they're stupid for choosing to smoke? Yes, but I'm not going to tell them to stop, or make some self-righteous comment evertime they light up, it's there choice to do whatever they wish with their bodies and I'm not going to deride or babysit them over it.
