Ahhhhh...........my daughter graduated in 1990 and during her high school years, they were able to smoke on the grounds. But a year before she graduated back then, the authorities put an end to it. They had to leave the grounds to smoke. Which was across the street at a store.
So, I don't know many High Schools today that allow students to still smoke on the grounds. That is pretty much gone.
When I was in high school in the early 80's, the kids used to stand outside the school by a back fire exit door, to smoke. They tracked in so much mud/leaves/grass clippings that the school relented and put down a blacktop pad about 30 feet on a side, so they would have a clean surface to stand on!
