I'm all for smoking being legal, but I don't think you should be allowed to smoke if you have children in your house. I don't care if the research on second hand smoke is unclear, it obviously isn't good to be breathing in. Not to mention the fact that it drains money away from families.
Is the research really unclear? Are there studies out there that say that second hand smoke may not be harmful?
There is really no ambiguity about the dangers of second hand smoke, which is why I have trouble reconciling my position on smoking with my personal actions (I readily admit this as a weakness - living in a municipality with a 'voluntary' public smoking ban, I generally attend establishments that allow it, which is unfortunate, as it increases my opportunities to smoke. Of course I am here referring to smoking outdoors in areas where there are employees and other patrons, as indoor smoking is disgusting not to mention an obvious fire hazard.) Tobacco is one of the more blatant illustrations of how supposedly 'personal' habits can have a detrimental impact on wider society.
Anyway, I smoke, but I definitely don't litter butts. What an eyesore.
