A wrongful death and medical malpractice lawsuit has been filed against a Vancouver, Wa., pain clinic by four plaintiffs who allege the clinic prescribed excessive amounts of pain medications, causing overdose deaths and addictions.

The estates of two patients who died of opiate overdoses are suing Vancouver Payette Clinic in Clark County, Wa., circuit court, along with two other plantiffs who allege the clinic prescribed them "grossly excessive" amounts of controlled substances that caused physical and mental injuries.
