A federal appeals court has approved a deal granting immunity to the Sackler family, owners of Purdue Pharma, from civil claims related to the opioid crisis. The plan will see Purdue Pharma become a new company, Knoa, with profits going to a fund to prevent and treat addiction. The family will contribute $5.5-$6 billion in cash over time, or around half of their collective fortune. This settlement is the latest development in the opioid crisis, and is hoped to help fund much-needed addiction programs.
