Query: It's Not About The Song

I own versions of the song Cocaine Blues by Bob Dylan, Keith Richards, Dave Van Ronk, Ramblin' Jack Elliott, Jackson Brown and probably one or two other artists, and I have heard conflicting stories about who wrote it. I thought this video was about the song. I was especially excited that the narrator is Hoyt Axton, because his version is my favorite, though I have never seen it on his records.It's not about the song. It is an anti-drug documentary. It is however, the best anti-drug documentary I know of, like the best house in a bad neighborhood.
