More states, territories and Washington, D.C., have signed on to a settlement with drugmaker Purdue Pharma and the Sackler family over the opioid crisis, officials said.

The multi-billion-dollar payment is meant to resolve claims that the drugmaker's pain medication, OxyContin, caused an opioid crisis.

The deal ends the Sackler family's ownership of the company and bans them from ever selling opioids in the U.S. again.
