I don't care if a person uses a drug, as it doesn't affect my health. But tobacco smokers directly effect me. I'm a very slow CYP1A1 metabolizer, which means that my lungs are not able to detoxificate smoke / air pollution like most people, and it effects me probably much more than you. Also if smoking is generally prohibited somewhere, I can go there to speak with the person to stop smoking, and that's enough for me, I wouldn't care if people did it _inside_ their own home.
