An arrangement of Oxycodone pills(Mark Lennihan/AP) Massachusetts could receive more than $500 million for addiction prevention and treatment from a $26 billion settlement between the states and the nation’s largest opioid distributors and a manufacturer. Three companies — Cardinal, McKesson and AmerisourceBergen — would pay $21 billion in total over 18 years. Johnson & Johnson, the drug manufacturer, would pay as much as $5 billion over nine years. “I promised the people of Massachusetts that the opioid crisis would be a top priority, that we would hold the bad actors accountable, and that the billion-dollar companies who got rich off the suffering in our communities would pay,” said Massachusetts Attorney General Maura Healey, whose office worked on this agreement. “Today’s announcement is another step forward in that work.”
