It wasn't that long ago that schools (even middle schools) had smoking sections for the students
I thought it was weird that the other high school didn't have a smoking area, because we were in a tobacco farming town, and a huge number of teens worked in the tobacco industry.

And of course, the teachers lounge was always smoke filled, walking in there was like walking into a bar at time, the air had a visible haze of cigarette smoke. I don’t know how the non smoking teachers could handle it.
