The first case in a flood of litigation against opioid drug manufacturers opened on Tuesday in Oklahoma.
Oklahoma Attorney General Mike Hunter's suit alleges Johnson & Johnson, the nation's largest drugmaker, helped ignite a public health crisis that has killed thousands of state residents.
Johnson & Johnson is the sole defendant in the case after two other companies — Teva Pharmaceuticals and Purdue Pharma — both settled with the state before the trial began.
