N2 - OBJECTIVE: Studies on drug dependence show a high prevalence of comorbidity with additional mental disorders. Comorbidity patients also show more poly-substance use and other psychosocial problems. This study analyzed the importance of comorbidity for the long-term course of opiate dependence. METHOD: 350 opiate-dependent patients were examined at yearly follow-ups over 4 years using the EuropASI for the assessment of drug-related problems and the CIDI for diagnostic of psychiatric disorders. 196 patients were reached at final follow up (56%). RESULTS: Of the patients reached at final follow-up, 30% had severe, 29% mild and 41% no clinically relevant disorders at baseline. However, the linear relationship at baseline--the more severe the disorder, the greater the impairment through drug-related problems--was not present at final follow-up. The results show that lifetime diagnosis of mental disorder had no prognostic relevance for the long-term course of drug dependency. CONCLUSION: The assumption that opiate users with an additional mental disorder are more vulnerable in their course of addiction could not be confirmed.
