At least they stayed away from the brown acid. That would have been a real bummer.
Yeah, but the Window Pane would have been pure...just kidding. Lysergic acid is not a drug anyone should take. The hallucinations are just too vivid and so many people thought they could do anything back in 60's and died.
Remember Timothy Leary who preached it was the next level of consciousness? He was so wrong. It was simply a thought-altering drug (as is alcohol - think beer glasses late at night) that gave the illusion of such.
