The National Institutes of Health (NIH), specifically the National Institute on Drug Abuse (NIDA), has issued a funding opportunity titled "Accelerating the Pace of Substance Use Research Using Existing Data." This initiative invites applications that analyze existing data to explore the causes, prevalence, and treatment of substance use disorders (SUD) and related health outcomes, such as HIV. The funding aims to maximize the utilization of public datasets to enhance understanding of substance use behaviors, their trajectories, and effective prevention strategies. The grant is not designated for primary data collection and encourages innovative methodologies, including big data analytics and artificial intelligence. Eligible applicants include various educational institutions, nonprofits, and governmental organizations, with a total funding commitment of $2 million for fiscal year 2026. Applications must be submitted by January 25, 2025, and are assessed based on scientific merit, innovation, and the potential societal impact of the proposed research. The program particularly emphasizes research addressing underrepresented populations and health disparities related to substance use and HIV. By leveraging existing data, the initiative aims to catalyze new insights into substance use disorders and inform public health strategies.
