Sounds like misinformation.
I've heard of cases like this, you don't take LSD and then get shot with half a clip and not notice it. This is PCP. I guarantee it. I've read many a horror story on pcp in which people have bitten, choped off their own limbs with axes, hurt children, and been thrown out of a cars windshield going 70, stood up and kept walking home.
that was totally pcp mark my words.
