title: [Clinical prognosis of schizophrenic patients with cannabis addiction. Between nihilism and hope].
abstract: Comorbid substance use disorders in schizophrenia are mostly associated with an unfavorable course of the disease and with difficulties in clinical management. Therefore, some therapists tend to react to these patients in a resigned manner. However, there is growing evidence for higher cognitive functioning and less severe deficits in brain morphology of these patients compared to patients without cannabis use. A common interpretation refers to relatively low vulnerability for psychosis in some of these patients, who mainly became schizophrenic because of the pro-psychotic properties of cannabis. Low vulnerability is reflected by a higher cognitive functioning; therefore, the pessimistic view of therapists seems unjustified for at least a subgroup of young patients. Provided that patients are treated in adequate therapeutic settings and that they stop using cannabis, a lower vulnerability may be associated with overall better socio-rehabilitative outcome parameters.
