A rationale for identification of cases of drug abuse

To overcome the blanket of secrecy developed by many drug-abusing populations, special strategies have been used to generate more reliable and valid data on the extent and nature of the problem. The epidemiological rationale for eight strategies to identify cases of drug abuse are reviewed along with their limitations and examples of their application. The choice of strategies in any given setting will depend upon the drug-use patterns and legal framework of the particular society, the form of social organization developed by drug abusers and the types of contact they have with formal institutions such as law enforcement and treatment agencies.
