Opinions - LSD In Fear and Loathing, possible?

[Handle]

"Aybody want some LSD? I got all the makin's right here!............All I need is a place to c-o-o-k........." [trails off]

No, not my boast, but that of a tall bespectacled hippie chemist in "Fear and Loathing in Las Vegas" [the movie, I'm not sure about the book].

This line has constantly bothered me, and I still don't know the answer. Is there any way, back in the sixties, certain precursors could have been legal that were so close to LSD they could be offered for cooking up in one night at a club?!

I know that LSD is one of the trickiest things to attempt, just so in depth, not like a pseudo red phos iodine shake and bake, but requiring the skills of a true chemist.

I also know that it normally takes a long time, certainly a few days in most cases, and that is the limit of my knowledge.

But that's today. Today when presursors are tricky and restricted, and people have starting points closer and closer to "scratch". What about in the early sixties, is it possible that along with Delysid and whatnot, Sandoz was peddling some legal research cousin that was close enough to be cooked up in one night at a party?! It sounds insane, and maybe it is.

Either way, I would welcome any clues on this topic, so I can finally put my nagging doubts to bed. Actually, the doubt is that it's not impossible, because I'm so certain that it cannot be done, my doubt goes the other way.

Maybe it's just like the notorious "mothballs and ammonia" bombs of Terminator fame...nice onscreen, but just a figment of pop culture.
