Attorneys general from 41 states across the country are working together on a comprehensive investigation into the opioid crisis. New York Attorney General Eric Schneiderman announced the coalition during a Tuesday press conference in New York City.

“We know that the system is broken but there’s never been as comprehensive an effort as the one we are launching now by a bipartisan coalition of attorneys general to get to the bottom of it,” Schneiderman said.

He said investigators have demanded information and documents from manufacturers and distributors to see if there were any illegal marketing or selling practices.

“Our subpoenas and letters seek to uncover whether or not there was deception involved, if manufacturers misled doctors and patients about the efficacy and addictive power of these drugs.”

So far the coalition has served subpoenas to four pharmaceutical companies; Endo International, Janssen Pharmaceuticals, Teva Pharmaceuticals Industry and Allergan Inc. It has also demanded information from three other corporations that manage roughly 90 percent of the nation’s opioid distribution.

“There’s no doubt that there simply are too many prescriptions for too many opioids in America right now,” Schneiderman said.

The attorney general said the main goal of the investigation is to initiate change and some companies have already indicated willingness to cooperate.

“We hope that this will lead to some reforms by the industry itself. There may be cases to be brought if there’s any fraud or deception.”

Schneiderman said opioid distribution alone is a $500 billion business annually.
