The U.S. Justice Department has filed a civil complaint against CVS Pharmacy, accusing the company of knowingly filling unlawful opioid prescriptions and contributing to the opioid crisis. The complaint alleges that CVS ignored warnings from its own staff and engaged in practices that violated both the Controlled Substances Act and False Claims Act, leading to potential civil penalties. CVS disputes the claims, arguing all prescriptions were legal and accusing the government of shifting standards. This lawsuit highlights ongoing accountability efforts regarding pharmaceutical practices amid the opioid epidemic.
