The National Institutes of Health (NIH) is offering a funding opportunity titled "NIDA REI: Reaching Equity at the Intersection of HIV and Substance Use," aimed at addressing health disparities related to HIV and substance use among underserved racial and ethnic populations. This initiative invites pilot or feasibility research that explores structural, organizational, and social factors contributing to these inequities, with a focus on promoting racial equity and developing innovative prevention and treatment strategies that consider intersectionality across various identities. Funding of up to $450,000 is available over three years for projects that demonstrate community engagement and address documented disparities in HIV and substance abuse outcomes. Interested applicants must submit their proposals by November 14, 2024, and can reach out to NIH Grants Information at grantsinfo@nih.gov for further inquiries.
