[Alcohol and drug abuse as risk factors for violence and delinquency in schizophrenic patients]

A study on the prevalence of substance abuse in schizophrenics performed in 1989/1990 had shown high rates of alcohol and drug abuse in schizophrenia. An additional analysis of the data revealed that schizophrenics with substance abuse had been convicted more often than other schizophrenics. The possible role of substance abuse as a risk factor for delinquency or casualties in schizophrenia is discussed.
