title: [Consumption patterns and motivation for use of addictive drugs in schizophrenic patients].
abstract: In particular studies conducted in the U.S. display a tendency for schizophrenics to combine hallucinogens and amphetamines, whereas other studies report on a combination of psychotropic substances with a similar range of action. Influencing negative symptoms is reported to be the motivation for consumption. A total of 222 patients with a schizophrenic disorder (F2) and addiction (F1) were examined. The main substance was alcohol (F10.1 or F10.2; 52.2%), followed by cannabis (F12; 25%), opiates (F11; 4.1%), sedatives or hypnotics (F13; 2.7%) and cocaine (F16; 0.5%). A multiple drug use (F19) is reported by 14% of them. The most frequent combination was alcohol and cannabis, whereas hallucinogens and amphetamines were only rarely combined. Actual multiple consumption was reported by 55% of the patients, while lifetime multiple consumption applied to 72%. The motivation seems to be an unspecified sedation of unpleasant affective symptoms of schizophrenia. The most frequently seen combinations do not correlate with the reports published in the literature. The great variations in motivation seem to mainly reflect the importance of the availability of the substance.
