Six major US tobacco companies have defeated a lawsuit by hospitals seeking compensation for treating patients with smoking-related illnesses.
Thirty-seven hospitals in the state of Missouri had claimed cigarette companies delivered an "unreasonably dangerous" product.
They sought more than $455m reimbursement for treating uninsured smokers who had not paid for care.
The hospitals treat many destitute, non-paying patients.
They said medical ethics required them to treat people in need, regardless of their ability to pay.
