Johnson & Johnson and three opioid distributors have agreed to pay billions to settle thousands of government lawsuits accusing them of helping to create the opioid public-health crisis.

The deal will have McKesson Corp., Cardinal Health Inc. and AmerisourceBergen Corp. pay approximately $21 billion to settle claims that they ignored unusually large opioid shipments. Johnson & Johnson will pay $5 billion to resolve allegations it illegally marketed opioids.

The Illinois Attorney General announced that the state will be signing on to the settlement and, if finalized by all local governments, would receive approximately $790 million. The majority of the settlement money would be spent on opioid treatment and prevention.
