The "Fatal Overdose Reduction Act of 2025" aims to increase access to treatment for opioid and substance use disorders by establishing a Health Engagement Hub Demonstration Program under Medicaid. This program will provide funding for states to create drop-in centers offering a range of medical and social services, including harm reduction, mental health care, and addiction treatment. The Act prioritizes serving Medicaid and uninsured individuals in communities heavily impacted by overdose, with a focus on evidence-based models and community involvement. It also requires comprehensive reporting and evaluation to assess the program's effectiveness.
