We also had a student smoking lounge in my suburban Chicago area high school in 1991! I think you had to have a parent sign a permission slip or something like that, and I don't know how it didn't run afoul of the law as few kids were 18. But it was always packed.

We had an outdoor spot with a roof and one wall called the smoking section. This was in California in 1982. I think they got rid of it in '83.
