It is kind of weird but I have nostalgia for cigarette smoke smell. When I catch someone on the street smoking I take a big whiff.

I will say bars do not smell better now that the cigarette smoke is gone. At least for some dive bars. That smoke was doing some heavy lifting...

In college, we had two bars that still had smoking despite it being banned in our state. The exception was it had to have doors and a completely separate HVAC. One bar had a smoking second story that had most of the pool tables and TVs while downstairs was a more relaxed area. Another bar bought out the building directly behind them and put a door connecting the two buildings.

Hookah bars got wrapped up in the smoking ban too which I think was an overreach. You go to a hookah bar to smoke, you don't go there to watch a game, shoot pool, and have a beer. The one hookah bar in town actually sued the state over it. Because they also sold hookah supplies, they were exempted.

The hookah supply loophole is interesting. I guess that would also explain cigar lounges as these are cigar shops as well. Vegas still also allows it I believe at least in some casinos. Vegas airport had smoking sections last time I connected through there too.
