Objectives To evaluate accuracy and feasibility of Nomination Method (NM) in estimating the number of illicit drug users in specific survey areas. Methods Total numbers of heroin users of 1999 in 6 survey areas were estimated by NM separately and compared with government-registered data to evaluate accuracy of NM in 2000. Prevalence of illicit drug use among the social network of drug users were also surveyed by nomination technique. Results The ratio of estimated figures of heroin users over registered ones were 1.2874, 1.3609, 0.8629 in 3 areas where drug-related data were available, respectively. Conclusions NM is a useful and feasible method in estimating the number of illicit drug users in a local area. Its accuracy depends on representativeness of core sample and reliability of benchmark and nomination procedure.
