Ohio is suing five drugmakers, alleging that the companies contributed to the opioid crisis by misrepresenting the addictive nature of their painkillers, the Wall Street Journal reports.

The lawsuit targets Purdue Pharma, Endo Health Solutions  (ENDP) - Get Report , Janssen Pharmaceuticals, which is part of Johnson & Johnson  (JNJ) - Get ReportCephalon and Allergan (AGN) - Get Report .

Ohio Attorney General Mike DeWine claims the companies weren't honest with doctors about the risks associated with the painkillers, noting that the companies marketed the drugs to general practitioners that may not have a specialty in pain management.

"The evidence is going to show they knew what they were saying was not true and they did it to increase sales," DeWine told the Journal.

"We share the attorney general's concerns about the opioid crisis and we are committed to working collaboratively to find solutions," Purdue Pharma spokesperson John Puskar told TheStreet.
