A new wave of plaintiffs has joined the opioid-epidemic litigation with five class actions filed on Tuesday: consumers who claim they’re seeing skyrocketing health insurance costs as a result of the crisis.

The suits, filed in five states, were brought by individual persons against opioid manufacturers and distributors, and are among the few class actions filed against drugmakers and marketers. The vast majority of cases have been separate actions brought by government entities such as cities and counties.
