Phencyclidine and chemical "stroking".

The current wave of drug abuse is but the latest manifestation of the real human need for "stroking." Drugs which affect the pleasure center of the brain are prime objects of abuse. Phencyclidine ("PCP" or "angel dust") is a cyclohexylamine which has properties of the amphetamine-stimulants, the narcotic-depressants and the hallucinogens. Previously unrecognized population groups include children less than six years of age and pregnant women and their intoxicated offspring. Successful treatment of present and future patients must be multidisciplinary and will ultimately depend upon a clear understanding of the pharmacology, social psychology, politics, and economics of drugs of abuse.
