Mission and Services
Who Are We?
The National Addiction and Health Data Archive Program (NAHDAP)’s mission is to facilitate research on substance use and health by acquiring, enhancing, preserving, and sharing data produced by research grants. NAHDAP supports secondary data analysis through technical assistance and specialized training for data depositors and data users in the substance use and health research and policy communities.
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 advance science on drug use and addiction and to apply that knowledge to improve individual and public health.
NAHDAP’s staff consists of professional researchers, data curators, project managers, technicians, and others working together to promote the sharing and use of data relevant to substance use and health researchers and policy makers.
