I used to live on a reservation in Northern Az. Scattered about the small town, I lived. There would be empty plastiq, water bottles, rubbing alcohol bottles, & hairspray cans. (Aqua net, baby!) As well. It did occure to me what it was all about. I had to ask anyways. I asked me friend at the times. Who's been living on the rez a few years before I arrived. He told me the story. That the natives, would buy a gal. of water, hair spray, rubbing alcohol. Mix it together. Call it "Ocean". Every now & then. You'd see one get hauld off on a stretcher. Not dead. Not that I've seen. But, that messed up. The Rez days. Way out there, man.
