COLUMBUS, Ohio (AP) — The opioid crisis is overwhelming Ohio's foster care system as record numbers of children are removed from the homes of drug-addicted parents, the state's children service advocacy group said Thursday. More than 15,500 children are now in foster care, up from about 12,600 four years ago, according to the Public Children Services Association of Ohio. The state is on track to place more than 20,000 children in foster care by 2020, the trend driven by the worsening opioid epidemic, according to the report.
