Mission and Services


The mission of the National Addiction & HIV Data Archive Program is to facilitate research on drug addiction and HIV infection by acquiring, enhancing, preserving, and sharing data produced by research grants, particularly those funded by the National Institute on Drug Abuse. NAHDAP supports secondary data analysis through technical assistance and specialized training for data depositors and data users in the drug addiction and HIV research and policy communities.

NAHDAP's staff consists of professional researchers, data archivists, and technicians working together to promote the use of data relevant to drug addiction and HIV researchers and policy makers.


NAHDAP is hosted by the Inter-university Consortium for Political and Social Research (ICPSR), the largest social science data archive in the world and part of the University of Michigan's Institute for Social Research. NAHDAP is funded by the National Institute on Drug Abuse, part of the National Institutes of Health. NIDA's mission is to bring the power of science to bear on drug abuse and addiction by supporting research across a wide range of disciplines and ensuring the rapid and effective dissemination and use of the results of that research to improve prevention, treatment, and policy.
