Interesting.
I remember a while ago there was suddenly many States in the US to enact smoking bans in bars/restaurants mostly one right after another. I remember when I was in high school they passed the law in my State and they had some people interviewed on the news about it. However, while I heard about "smokeasys" existing (term comes from prohibition era speakeasys) I have never seen one and I've been to a lot of bars in many areas and various States. Some people complained but compliance was basically a non issue.
As a result, I think younger smokers are now just used to going outside to smoke, I don't know hardly anyone who smokes in their house and those that do seem to be really old. Very very few non-smokers let smokers smoke in their house, and hardly any smokers ask, they just walk outside. This wasn't the case even 15 years ago.
It wasn't really that long since the law had passed, but several (probably 6) years ago I went to the American South and I was asked "smoking or non-smoking" and it was so weird, even though that's basically how I grew up! When I was a kid teachers smoked in the teacher's lounge, in school.
However hookah bars are allowed to exist almost everywhere as far as I can tell, and I really never understood how that fits into the law.
Also a few States allow exceptions for private clubs so places like the VFW (Veterans of Foreign Wars) allow smoking.
Also, some except casinos, for whatever weird reason.

Any other places these laws are loosely enforced?
