PCP (phencyclidine) is a Schedule II controlled substance that was originally developed as an anesthetic but was discontinued for medical use due to side effects. It can be a white or brown powder or liquid that is often smoked, snorted, or dissolved in drinks to be consumed. Short term effects include hallucinations, aggression, lack of pain/rational judgment, while long term effects include memory loss, psychosis, paranoia and brain damage. It is known by street names like Angel Dust, Peace Pill, and Embalming Fluid.
