Abstract
Two of the major methodologies applied to estimation of the number of heroin abusers, survey research methods and the capture/recapture technique, are reviewed. The flexibility of the capture/recapture approach in handling not only the dependence of samples of heroin users but also the nonhomogeneity of sampling probabilities, allowing estimation in populations which are mixtures of qualitatively different heroin user types, is shown. Models with these features are illustrated using both simulated and real heroin abuse data.Keywords
