The main purpose of this legislation, known as the Addressing Addiction After Disasters Act, is to enhance the support provided to individuals dealing with substance use and alcohol use disorders in the aftermath of disasters. It aims to amend existing disaster relief laws to ensure that these critical services are included alongside mental health support during times of crisis. Key provisions of the Act include the expansion of the types of assistance available under the crisis counseling program established by the Robert T. Stafford Disaster Relief and Emergency Assistance Act.
