title: Evaluation of drug taking behaviour. Some theoretical and methodological considerations.
abstract: Evaluation of treatment modalities of drug dependence has specific theoretical and methodological difficulties. Ideological and invested interests also complicate the literature. This paper analyses the situation on different levels, concentrating on controversies about theoretical concepts, and problems connected to the variability of drug taking populations. Some suggestions are given.
