This week, Johnson & Johnson was ordered to pay $572 million US to the state of Oklahoma, in a landmark case that saw the court find the company liable for the state's opioid crisis. Johnson & Johnson says it will appeal the ruling. Purdue Pharma is also proposing to settle thousands of cases.

Today on Front Burner, we talk to journalist Zachary Siegel about what this ruling might mean for the thousands of cases soon to be before the courts.
