Lifetime substance abuse comorbidity is frequent in schizophrenic patients, but the clinical correlates remain unclear. We have explored the chronological relations between substance abuse and course of schizophrenia, and compared several clinical characteristics and personality dimensions in 50 schizophrenic patients with or without lifetime substance abuse or dependence. Abuse occurred mainly after the first prodromal symptoms and just before the first psychotic episode. Substance-abusing patients were not different from non-substance-abusing patients on the Chapman Physical Anhedonia Scale, PANSS total score, negative subscore or depression item, CGI, treatment response and demographic variables. In contrast, substance-abusing patients had higher scores on the Barratt Impulsivity Scale (total, cognitive and non-planning scores) and had attempted suicide more often. In patients with schizophrenia, as in the general population, substance abuse or dependence appears associated with higher impulsivity and suicidality. High impulsivity could facilitate substance abuse as a maladaptive behavior in response to prodromal symptoms, precipitating the onset of a characterized psychosis.
