Secondhand smoke linked to higher risk of stroke

The increased risk of stroke that comes with smoking may extend to nonsmokers who live in the same household and breathe in secondhand smoke, a U.S. study suggests. Researchers found that never-smokers who had a stroke were nearly 50 percent more likely to be exposed to secondhand smoke at home than people who had never had a stroke. During the study, stroke survivors exposed to secondhand smoke were also more likely to die from any cause compared to those without secondhand smoke exposure.
