Walmart on Tuesday announced it agreed to a $3.1 billion nationwide settlement designed to resolve all the potential state lawsuits it faces for its alleged role in fueling the opioid epidemic.

The settlement framework, subject to the review and approval of involved states, would address years of litigation for the retail giant at the state, local, and tribal level regarding the actions of its pharmacists and their contributions to the opioid epidemic. Walmart continues to deny all related allegations but said it believes the settlement is “in the best interest of all parties and will provide significant aid to communities across the country in the fight against the opioid crisis.”

“Walmart strongly disputes the allegations in these matters, and this settlement framework does not include any admission of liability,” the company said in a news release. “Walmart will continue to vigorously defend the company against any lawsuit not resolved through this settlement framework.”
