Tom, you can't really believe that cigarettes don't cause cancer, and don't have adverse effects on people's health. I understand you run a tobacco shop, but seriously.
I grew up in a household of smokers (my parents and sister both smoke), as well as a large extended family of smokers (most of my cousins and aunts); part of me feels like I've inhaled enough second-hand smoke already, I don't need it when I go into restaurants and bars.
