I went to the UK and France in 2004. Got to go back to France last year; I was going to say it’s like the U.S. in the 1990s but it seems like they’ve banned indoor smoking in most buildings so it is better than that. There are still a lot more people smoking in outdoor sections than I’ve experienced in the U.S. for about 20 years, though. I’ve gotten so used to smoking being rare in the U.S. that it felt weird to see (relatively) so much in France.
A lot of Japan as well, though the laws changed to ban it in some places prior to the olympics so (Tokyo, at least) isn't nearly as smokey as it was before corona and the olypmics.
