I didn’t yet know that a single batch of heroin was about to land in Huntington, West Virginia, four hours west of Jones’s cell, that would halt the breathing of twenty-six people in a single day, before the week was out. Those overdoses were fueled by the latest synthetic opioid, carfentanil, imported from China with a stroke on a computer keyboard. Carfentanil is an elephant sedative one hundred times stronger than fentanyl, which is twenty-five to fifty times stronger than heroin.
