Lot’s of high schools in Virginia did.
Yep. The teachers' lounge inside was a cloud of smoke and we had our own smoking section for us students outside. Once in a while a teacher would join us.
My brother is an occasional smoker and elementary school teacher. He's not allowed to possess tobacco anywhere on school grounds, even in his car. He's all but quit and switched over to e-cigs. He says there's few worse transgressions a teacher can do than to show up to class smelling like smoke.
My 4th grade teacher used to smoke at his desk before the morning bell rang.
Different times...
My H.S. Chemistry teacher smoked in the store room attached to the classroom/lab. He started a fire in there one day, because a burning cigarette fell off the ashtray into a wastebasket filled with paper.
