I remember visiting Europe a few times over the decades (late 80s through early 2010s). I'd noticed an increase in smoking in Europe as I was noticing a decrease in the US. Someone might have more specific numbers/details/charts, but IIRC, cigarette companies were starting to ramp up marketing outside the US as they could see legislation coming and social support waning.
In my experience, it's still pretty prevalent in Central and Eastern Europe. I was able to smoke in a restaurant in Bulgaria three years ago, and you get nothing like the social disapproval for smoking you tend to in Western Europe (I've since stopped smoking cigarettes.)
It seemed relatively prevalent in Romania when I visited in 2018. And I didn't see it everywhere in Moscow in the early 2010s, but there was more of it than we see in the US daily. And... the other side of that is we have a lot more obese folks in the US than I've seen in various European places. We might be healthier from a smoking standpoint, but probably less healthy in other ways.
