where i found it: i didn't, it barely exists (other than on Amon Duul records)
I've have never tried Salvia and don't really even know what it is. It's apparently a legal psychedelic, maybe like smoking banana peels or toothpaste coated cigarettes or whatever other kind of shit that junior high school kids come up with to get high. Obviously it's hallucinogenic and causes marked dissociation. This guy likes to smoke it and try to garden, drive or write letters to Congress. Kind of disturbing to watch, but also sort of funny.
While we're on this topic, HERE's A LINK to an interview with a woman who appears to be a past psychedelic princess who reigned over a grain silo, but then got in over her head and now is an internet guru.
