I forgot about glue sniffing. I used to build models (rather badly), fighters and whatnot usually. I recall when you couldn't just buy glue. It smelled pretty good actually, but I never wanted to get high on the fumes.
I once was doing a hot recrystallization using ethanol as solvent and very suddenly got drunk, really drunk, really fast, breathing fumes. About 5 minutes later I was sober, but I had to sit down.
