The Office of Substance Use Initiatives was created by the Will County Executive, Larry Walsh, after receiving the Prescription Drug/Opioid Overdose Related Deaths (PDO) grant by the Illinois Department of Human Services (IDHS) and funded by the Substance Abuse and Mental Health Services Administration (SAMHSA) to further its efforts in combating the opioid overdose epidemic. Will County is part of the Statewide Illinois Opioid Crisis Advisory Council.
