St. Louis County on Wednesday filed its civil lawsuit against multiple opioid drug manufacturers alleging a “widespread campaign of unfairly, deceptively, and fraudulently marketing and promoting opioids” in violation of Minnesota Law.

St. Louis County Attorney Mark Rubin said he filed the suit, in the works for months, against Purdue, Teva, Janssen and Endo enterprises.

The ten-count complaint includes claims arising under Minnesota’s public-nuisance statute, False Claims Act, Prevention of Consumer Fraud Act, false-advertising statute, Unlawful Trade Practices Act, and Uniform Deceptive Trade Practices Act, as well as state-law claims for fraud, negligence, gross negligence and unjust enrichment.

The lawsuit was approved in November by the St. Louis County Board. The suit asks for damages, penalties and an injunction prohibiting future violations.

The case is similar to hundreds of other cases filed by states and local governments across the country in response to the opioid epidemic, with government officials alleging the companies knew their products were being aimed at vulnerable adults and were causing addiction that spurred massive social costs, including medical, law enforcement, social service and prison costs as well as premature deaths.
