PCP is sometimes sprinkled on marijuana or parsley and smoked. Although PCP is illegal, it is easily manufactured. It is often sold as mescaline, THC, or other drugs. Sometimes it may not even be PCP, but a lethal by-product of the drug. Users can never be sure what they are buying since it is manufactured illegally.
Effects depend on how much is taken, the way it is used, and the individual.
Effects include increased heart rate and blood pressure, flushing, sweating, dizziness, and numbness. When large doses are taken, effects include drowsiness, convulsions, and coma. Taking large amounts of PCP can also cause death from repeated convulsions, heart and lung failure, or ruptured blood vessels in the brain. PCP can produce violent or bizarre behavior in people who are not normally that way. Regular PCP use affects memory, perception, concentration, and judgment.
