The plummeting rates of smoking in the US is one of the rare areas where this country really shines when it comes to social welfare. Even many European states that have what I'd consider much more progressive social welfare systems have smoking rates that are appalling, often 3x or more the US rates.
On the other hand, being constantly ostracised from public spaces isn’t great either… something I find infuriating when I travel abroad. If there were at least a few smoking bars where you don’t have to go out into the cold to smoke I think that would be nice.
I'm a smoker, and I absolutely don't want smoking allowed in public indoor places, and some outdoor public places as well. I don't smoke indoors even in my own home.
On the other hand, when I duck down an empty alley and light up, I'm going to be annoyed if someone walking on the main road comes in to complain about how my second-hand smoke is going to give them cancer.
Too many times I have had people go out of their way to inhale my second hand smoke, and then complain about it.
