Phencyclidine (PCP); also, a marijuana cigarette laced with phencyclidine.
“This was some other shit, what they smoked, could have been fucking angel dust sprinkled on, they called that KJ. Shit, knowing them that’s exactly why I couldn’t stop my head from bobbing, and why the streetlights were so fucking bright, and mean seeming, and, like, too red. I was glad I only hit it once.”
