I saw a man in one of the emptier quarters 'huffing' what looked to be a bottle of duster for two full hours. He would suck on it for five minutes at a time, sit moribund for awhile, look around to see if he was being observed, (I was staring pretty blatantly. I don't think he could have made out a mountain if he was standing on it.) and then go back to hitting it again. It was a very disturbing thing to see, yet at the same time amazing.
He was a White man, around my own age, and wearing a 'Juggalo' medallion. far be it for me to claim that that's either here or there.
