Attorney General Josh Shapiro just effectively declared war on opioid manufacturers, according to WHYY.

Joining the forces of attorney generals from a minimum of 25 other states, Pennsylvania Attorney General Josh Shapiro declared he’s taking an in-depth look at opioid manufacturers.

The announcement is in reaction to an active lawsuit from several states alleging that drug manufacturers helped to create the opioid crisis.

While the actual number of states have not been confirmed, Shapiro stated that, "I want you to know that I will follow the evidence to hold everyone, everyone accountable and responsible no matter how big or powerful they are," said Shapiro.

Others have filed lawsuits recently, including Mississippi, Ohio, and counties in Illinois, New York and California.

"This is a broad, bipartisan, multi-state investigation of which Pennsylvania is one of the lead states. We have made great progress in it, and we're going to continue to work diligently in this effort," Shapiro adds.

Drug overdoses killed more than 4,600 people in Pennsylvania last year.
