It’s way too broad a comparison. In my North Eastern US state, encountering smokers isn’t that common because it’s illegal inside and anywhere near a door. So to smoke, you have to pretty much hide. And it’s become uncommon enough, smoking makes you a pariah so people seem to be breaking the official rules less often as time goes on due to social pressure more than fear of enforcement. We were out at a bar the other day and a guy smoked on the patio and it very much stood out. You could feel the vitriol for this guy in the atmosphere and after a minute he walked in to the parking lot looking embarrassed. Not that long ago a waitress would have brought him an ash tray.
But go to Kentucky, there’s no rules about smoking anywhere. Last time I was there, we went to a grocery store with an ashtray between isles. Every building we went in to smelled like the 80s.
These are both the USA. And then in Europe, you do have countries like Bulgaria, Turkey, and Greece where more than 25% of the country smokes, which is higher than anywhere in the US. But then you have Sweden with only 6% and Norway with 7% which is a little bit better than anywhere in the US.
