Cocaine abuse among schizophrenic patients.

Author information

  • 1Department of Psychiatry, VA Medical Center, Charleston, SC 29403.


Initial studies have indicated that stimulant abuse is prevalent among schizophrenic persons. To assess the phenomenon of cocaine abuse by patients with schizophrenia, 17 male cocaine-abusing schizophrenic patients were compared with 22 male schizophrenic patients who did not use cocaine. The cocaine-abusing subjects had been hospitalized more frequently, were more likely to be of the paranoid subtype, and were more likely to be depressed at the time of interview. It appears that cocaine abuse may influence both the psychopathologic presentation of schizophrenic patients and the intensity of care that they require.
