I have no sympathy for anyone who smokes, but I do worry about this big brother attitude we all have accepted. First the smoker, and before you know it there will be sin taxes on sugar, butter, meat. We already have it for alcohol, and other vices. You simply are missing the big picture.
Soon and currently the EPA is and will be taxing your carbon use. You will be big brother-ed into poverty. Don't fret that is OK because Big Brother will subsidize your vegetables, and solar cells from all the evil doers, and finally they will subsidize your bicycle from Chevron, Exon/Mobile, and British Petroleum.
China is loving our abandonment of heavy industry, China cares little for pollution, balancing hiring practices, or class action law suits. No doubt you will probably love poverty in your Utopian world, at least you will only be dying from poverty related issues. And since you value studies so much there are numerous studies that show conclusively that poverty reduces health, and your life length by more than any other vice by a lot.
