The National Institutes of Health (NIH) is inviting applications for the R21 Exploratory/Developmental Research Grant under the funding opportunity titled "Accelerating the Pace of Drug Abuse Research Using Existing Data." This initiative aims to support innovative analyses of existing datasets to investigate substance use behaviors, including alcohol, tobacco, and HIV prevention, without the need for primary data collection. The program is particularly significant as it seeks to leverage previously collected data to enhance understanding of drug use etiology and epidemiology, ultimately guiding effective prevention and treatment strategies. Interested applicants can apply for funding up to $275,000 over a two-year period, with a total funding availability of $2 million for fiscal years 2023-2025. The application deadline is November 15, 2024, and further inquiries can be directed to NIH Grants Information at grantsinfo@nih.gov.
