I've forgotten the details but this test was conducted by professionals in a hospital setting. The patient was asked to draw a self portrait and then he was given his acid. They asked him to draw his portrait at regular intervals until the trip was finished and then asked him to draw the final portrait. I think it took place during the early 1960's in the Czech Republic.

A typical fucking prick
parting vulgar flowers
the scent of week old piss mingling
with the seed of others
His paranoia runs deep
but only when She's on top
learning to ride horses
spitting venom
make me feel something anything you whore

strings of mirror balls
gushing
from every orifice
vibrating.. pulsing with the echoes of MAMA
tentacles of light gagging their eyes
blind cats clawing at each others nipples
like hungry needy babies desperate for milk
milk
milking dead snakes

flashback
mutilating dolls
because thats what little girls do
until they shed their skin
to fashion anti-fashion leashes
to lead their masters by
