Purdue Pharma and the Sackler family have agreed to a new $6 billion deal with a group of states that previously rejected the company’s bankruptcy plan. Like previous deals, money would go toward addiction treatment, and the Sacklers would give up control of Purdue, maker of OxyContin. It would also shield the billionaire Sackler family from current and future civil suits over their role in fueling the devastating opioid epidemic.
