Part II of the Annual Reports Questionnaire (ARQ) provides Member States with a mechanism for reporting data on drug abuse under the international drug control treaties.

The present publication, Annual Reports Questionnaire, Part II: Extent, Patterns and Trends of Drug Abuse: Guide to Completion, was prepared under the Global Assessment Programme on Drug Abuse as part of GAP Toolkit Module 4: Management of Data for the Annual Reports Questionnaire, which also comprises a set of four interlinked training packs designed to assist Member States in completing and interpreting part II of the questionnaire for purposes of policy formation and implementation of demand reduction activities.

Module 4: Management of Data for the Annual Reports Questionnaire forms one component of the GAP Toolkit, a compendium of methodological guides on drug abuse epidemiology, produced to assist States Members of the United Nations in developing systems of drug information collection that are culturally appropriate and relevant, in bringing existing drug information systems into conformity with internationally recognized standards of good practice and in harmonizing drug abuse indicators. The other modules in the Toolkit series provide support in the following areas: developing an integrated drug information system, estimating prevalence, conducting school surveys on drug abuse, basic data analysis, qualitative research and focused assessments, and ethical guidelines in drug abuse epidemiology.
