Walmart has reached a settlement with the US Department of Justice over a lawsuit accusing the retail giant's pharmacies of unlawfully dispensing opioid prescriptions in violation of the federal Controlled Substances Act. Both parties confirmed the agreement on Friday without disclosing financial terms, though Walmart stated the amount was "immaterial" and did not admit liability. The case, first filed in December 2020, was considered one of the Justice Department's most significant actions against a single company over the opioid crisis, which has claimed more than 905,000 American lives since 1999.
