The National Institutes of Health (NIH), through the National Institute on Drug Abuse (NIDA), is offering a funding opportunity under the HEAL Initiative for the JCOIN Phase II Clinical Research Hubs, aimed at addressing substance use disorder (SUD) and overdose risks within the criminal-legal system. This initiative seeks applications for multi-site clinical trials that evaluate strategies to improve treatment engagement, retention, and health outcomes for justice-involved individuals, particularly focusing on the delivery of medication for opioid use disorder (MOUD) in jails and community settings. The funding, which can reach up to $5 million over five years, is intended to foster collaboration among justice and behavioral health providers, with a requirement for a Plan for Enhancing Diverse Perspectives to ensure inclusivity in research. Interested applicants must submit their proposals by January 22, 2025, and can direct inquiries to grantsinfo@nih.gov for further information.
