The "Addressing Addiction After Disasters Act" expands the scope of disaster relief under the Robert T. Stafford Disaster Relief and Emergency Assistance Act. Specifically, it amends Section 416, which governs the Crisis Counseling Assistance and Training Program , to explicitly include services for substance use and alcohol use disorders alongside existing mental health services. This change authorizes the President to provide these critical addiction-related services to individuals affected by major disasters. Furthermore, the bill mandates the Federal Emergency Management Agency (FEMA) to review and adjust its application processes and guidance documents within 180 days to reflect the inclusion of these new services. Finally, it requires the Government Accountability Office (GAO) to conduct a review of the program, assessing the duration of assistance and FEMA's compliance in targeting disaster-related issues.
