New Jersey Attorney General Gurbir Grewal announced that the state is suing pharmaceutical company Janssen due to claims that the company misled its customers when it to comes to opioids.

The lawsuit is about the drugs Nucynta and Nucynta ER. Grewal claims that the company, which is owned by Johnson and Johnson, engaged in a long list of deceptive practices to increase sales of the drugs. The attorney general says that the company committed fraud in its marketing of the two opioid drugs.

“They funded bogus research. They pushed bogus theories like pseudo-addiction, things that have been debunked. They position Nucynta and Nucynta ER as a safer alternative to other, more powerful opioid drugs…when in fact they were the same types of opioid drugs,” Grewal said.

Janssen sold the rights to both drugs in 2015 for $1 billion. The attorney general is looking to get back some of that money calling it “ill-gotten gains.”

News 12 New Jersey reached out to Janssen for comment, but did not hear back.
