Chesterfield County is the fourth-largest populated county in Virginia. In 2014, the county experienced 53 fatal and nonfatal heroin overdoses. That number increased to 254 in 2018. In 2016, the Chesterfield County Jail began tracking opioid intake numbers. That year, there were 406 opioid intakes. In 2018, there were 537. The Chesterfield County Sheriff's Office (CSO) is responsible for the operation of the county jail. The CSO is working with the Chesterfield Mental Health Support Services (MHSS), the Chesterfield County Community Services Board (CSB), and Community Corrections to implement a MAT program for justice-involved individuals. The CSO is making extended-release naltrexone available to opioid-dependent individuals nearing release. Upon their release, individuals will continue to receive MAT and counseling through CSB or another pre-arranged community provider.
