What is PCP and LSD?

Completely different compounds.

PCP - anaesthetic originally developed to take the 'mind' off of a wounded mammal (human or animal) while surgery was performed on them, often combat related.

Hard harsh drug, does physical damage, cell damage, something like that. Not really addictive at all. Warps distance and shape perception. NOT PSYCHEDELIC. Nothing like LSD. Does not change colors and only messes you up, not enlightens you.

LSD - safe psychedelic, mind-expanding compound made from a Rye fungus. Not addictive, does NO physical damage whatsoever, nor brain damage, unlike PCP.

there is tons of literature on LSD, go rent a book!
