Nevada Attorney General Aaron Ford announced Monday that the State of Nevada filed an expanded complaint concerning opioids.

The lawsuit alleges that the manufacturers, distributors, pharmacies, and individuals created a system of addiction with deadly consequences. 

The complaint lists over 40 defendants including Teva Pharmaceuticals, Actavis Pharma, Purdue Pharma, members of the Sackler family which controlled Purdue Pharma, SpecGX LLC, Mallinckrodt LLC, as well as top executives of Insys Therapeutics. Distributor defendants include McKesson Corporation, Cardinal Health LLCs, AmerisourceBergen Drug Corporation, Walgreen Co., Walmart Inc. and CVS Pharmacy.

Legal causes of action include violations of Nevada’s Deceptive Trade Practices Act, False Claims Act, Racketeering Act, negligence, and public nuisance. Purdue Pharma defendants also face allegations of violating a 2007 Consent Decree with the state. 

The State joins other Nevada entities who have pursued similar litigation.
