A smoker puts out a cigarette in a public ash tray in Ottawa on May 31, 2016. Three national health organizations want Canada's premiers to push for initiatives to reduce smoking during settlement negotiations with major tobacco companies and their multinational owners, which provinces sued to recover health-care costs. In an open letter, the Canadian Cancer Society, the Canadian Lung Association and Heart and Stroke say governments should make cutting tobacco use a top priority in talks that began four years ago as part of the provinces' lawsuits seeking a collective $500 billion in damages.
