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.
All health issues aside, it’s just disgusting. It smells awful, it makes everything else smell awful. I always hate ending up in an elevator with a smoker, it’s nauseating. It truly is a disgusting habit.
