Do you drive a car? Burn oil in a furnace? Wear perfume? Eat peanut butter? Or exhale?
Got a few posters here who would sign banning dihydrogen monoxide petitions ;)
Most people drive cars because they have to to get to work or school or grocery shopping. They have little choice in the matter. But smoking a cigarette is a choice, one that is not necessary to conducting life’s business, and it also subjects other people to the bad effects of second hand smoke. That is why there are so many laws against it now.
Sure, go ahead and kill yourself with your nasty, filthy cigarette habit, but don’t be so callous or angry or bitter or selfish that you expose others to your added risks.
