In his book, "Living With The Dead," former Jerry Garcia manager Rock Scully describes Garcia as not liking powder heroin (due to the Nod, which is funny, as he was called Chief Smoking Moccasins due to his propensity for setting off fire sprinklers on entire hotel floors while dragon-chasing and falling asleep with a lit cigarette which would land on his moccasins which would then start smoking. I understand Jerry had stress when about to do a tour of the East Coast of the USA as he was less able to find it than on the West Coast, and wanted to blow off a tour of Europe for the same reason until he called Peter Townshend who didn't know where to find it but called I believe Keith Richards who apparently met Jerry at the airport with an ample supply. I also recall before a Jerry Garcia Band concert at Glassboro State College in New Jersey, Garcia was a guest on the college radio station and kept saying stuff like "Does anyone want to get DOWN with me? Come on DOWN and help Jerry get DOWN" and stuff like that with the emphasis on the word down. This was maybe in 1981 or so before his then 4-year long heroin addiction became well-known. It flipped me out at the time. Anyway, does anyone know anything about this Persian base? I found this site http://www.harmreduction.org/pubs/PUBSpdfs/heroin.pdf but it's taking ridiculously long to load on my dial-up. This site refers to "Iranian Base heroin" which, as "Persian" is merely the old term for "Iranian" is likely the same thing. Plus, the paragraph says it appeared on the British circuit in 1978-79 which sounds right, as Garcia said he was turned on by a guru in 1977 or 78 and knew right awat that he ould continue to do it. Again, does anyone have any knowledge/experience with it. I figure You could probably provide some information. Thanks!
