Purdue Pharma and its Sackler family owners have reached a new $7.4 billion settlement to resolve thousands of lawsuits alleging that the pain medication OxyContin caused a widespread opioid addiction crisis in the U.

Purdue Pharma and the Sackler families agreed Thursday to increase their financial contribution to $7.4 billion to resolve mass opioid litigation.

A group of 15 states have reached a tentative new deal that would require them to set aside hundreds of millions of dollars from the settlement in a legal-defense fund for the family.
