Johnson & Johnson's Janssen Pharmaceuticals and three other drug companies have agreed to move forward on a $26 billion global opioid settlement, the second largest multistate agreement in U.S. history.

The deal, announced July 21, was contingent on a certain percentage of states, cities and counties participating. Today was the deadline for the defendants to decide whether the participation rate was enough to resolve the vast majority of more than 4,000 opioid claims brought by governments across the country.
