SIGNS/EFFECTS OF USE: PCP has some similarities to hallucinogens, but also belongs in a category of its own. It can also demonstrate properties of both stimulants and depressants. Originally used as an anesthetic in the late 1950s/early 1960s, it was quickly discontinued because of its negative effects including delirium, visual disturbances, extreme distress, hallucinations, confusion, and, in some cases, violence. Research also indicates a link between psychological disturbances and long-term memory loss. A person on PCP may exhibit slurred speech, blank stares, muscle rigidity, disorientation, and excitement; they may feel a loss of personal identity. Most PCP users consume the substance by smoking, sometimes in combination with another substance such as marijuana. PCP can also be absorbed through the skin. Usually, the duration of the high is about 4-6 hours. Users can develop tolerance to the substance, meaning that they have to consume it more often or in higher doses – or both – in order to experience the same effect.

WITHDRAWAL: The withdrawal symptoms of PCP are similar to those of ketamine. Some long-term users of PCP exhibit decreased reflexes, dulled thinking, uninhibited impulses, depression, and lethargy among other symptoms. Because of the risk of relapse and the varied levels of PCP over the course of time, it is highly recommended that a withdrawal program be completed under the guidance of a physician. Reduction of sensory stimulation is an important step in the treatment of PCP intoxication. If the user has exhibited violent behavior, the doctor may choose to sedate the user through medicine, or, in some cases, the patient may need to be physically restrained until the threat of violence has passed.
