"There is clear evidence that Purdue ignored their responsibility to stop the diversion of OxyContin into the black market, directly leading to the heroin crisis on our streets today," Ray Stephanson, the mayor of Everett, in the western state of Washington, said in announcing the suit.
"Their drive for profit caused this epidemic, which has overwhelmed our treatment and emergency systems."
The first-of-its-kind civil suit asks that the drugmaker be made to pay the costs of handling the crisis as well as punitive damages.
The company agreed to pay more than USD 600 million in fines in 2007 for minimizing the risks of its blockbuster pain reliever pill.

The suit filed by city officials in Everett, which has a little over 100,000 residents, accuses Purdue of allowing OxyContin to flood the city's streets in total disregard for the community's wellbeing.
"Purdue placed profit over the health and safety of our community, and we can see the tragic results of that decision throughout Everett," Stephanson said. "We've already invested significant taxpayer dollars to deal with impacts of opioid addiction in our city, and we know that substantial additional resources will be needed to deal with this crisis in the coming years."
"We only have a 16-bed detox center in our county right now... But on any given day we have 10 times that many people detoxing in our jail," city spokeswoman Meghan Pembroke said. "The scope of the problem is so big that without additional resources, we don't feel like we're going to make significant progress."
A representative for Purdue told AFP in a statement that the company shared public officials' concerns about the opioid crisis and was committed to help find solutions.
"Although OxyContin accounts for only two per cent of all pain-related opioid prescriptions, Purdue is an industry leader in abuse deterrence as we were the first pharmaceutical company to develop an opioid medication with abuse-deterrent properties," Bob Josephson said.
