I wouldn't stand it right now, but it was everywhere so it wasn't annoying. I think smell adjusts to certain things not just temporarily but also on some longer periods. As a kid I wouldn't notice which friends parents smoked at home and which didn't, even though I came from a non-smoking home. And most of them lived in small apartments, so it must have been reeking.

I don’t smoke, but my mom smokes heavily. Whenever my wife (whose parents did not smoke) and I visit my parents, she always remarks afterwards on how terrible the smell was but I never really notice it at all despite having lived on my own for 15+ years now.

I really think it’s just something your brain blocks out, it doesn’t smell like much to me.

When I was an intern in the 1990's, I was on a team of old unix greybeards. Every 20 minutes or so, someone would have to go outside for a smoke break and they invited me along because that's where all the good design discussions would happen. Even today, I immediately recognize the smell of Marlboro Lights if I walk past a group of folks smoking outside.

I grew up in a town with a lot of feedlots, and I still don’t notice the smell when I visit. I definitely think your brain will block out background smells you grow up with. I wonder if that’s how people were able to live in medieval towns without sewers.

I was in morocco last month. everyone smokes there. I'd just be minding my own business whne randos would start lighting up next to me indoors. absolutely zero consideration for how nonsmokers feel about it.
