   Fuck you pharmapoisons. I took the best L on the planet back in the
   60s, and even THEN 99 percent of what was going around was ABSOLUTE
   GARBAGE.
   Now it's ALL garbage, and so is you delusion that it came from some
   Czechoslovakian lab where they have a secret stash of Ergotamine
   Tartrate, a warehouse full, and the Indole too! Number #35 Blue
   Sylvania bulb? Nah! The DEA and every other drug enforcement agency on
   the planet isn't going to notice when you order a case of them...
   Right. Sure.
   Here's someone who knew Owsley personally on the topic.
   March 15 2011 Travus T. Hipp Morning News & Commentary: Owsley, The Man
   Who 'Changed The Minds' Of An Entire Generation... Literally... Passes

   Here's a synopsis. Owsley was a SPEEDFREAK, and the ONLY THING that
   made him different than any other cooker was HE TRIED THE SHIT BEFORE
   HE SOLD IT, instead of using YOU as the guinea pig.
   He knew shit about chemistry. His GF was studying at UCB and was mostly
   responsible for making sure he did it sort of right.... when he wasn't
   too spun.
   As Gil Scott-Heron put it the only problem with streetcorner chemists
   is they can't remember if it's a little bit of this, and little bit of
   this and a LOT of that... Or was that a littttlllle biiitttt offff
   thiiis and A lOT oF tHaT?
   Cued up ... Live in '83 right here...
