The State of Oregon is filing a lawsuit against opioid manufacturer Endo Pharmaceuticals for deceptively marketing their powerful drug Opana for more than a decade. The complaint alleges that Endo misrepresented the risks and benefits of the extended-release opioid similar to Purdue Pharma's OxyContin. The lawsuit highlights connections between legal action against Purdue and Endo.

Oregon is also one of nine states fighting Purdue Pharma's bankruptcy and 4.3 billion dollar payments to several states.
