The state of Oklahoma alleged at the start of the first trial to result from lawsuits over the drug crisisthat Johnson & Johnson's greed led the drugmaker to use deceptive marketing to create an oversupply of painkillers that fueled the U.S. opioid epidemic.Reuters reports that Oklahoma Attorney General Mike Hunter, argued in a state court in the city of Norman that J&Jshould be forced to pay for helping cause the "worst manmade public health crisis in our state's history."The non-jury trial came after Oklahoma resolved claims against OxyContin maker Purdue Pharma LP in March for $270 millionand against Teva Pharmaceutical Industries Ltd on Sunday for $85 million, leaving only J&J as a defendant.
