Inhaling secondhand smoke? It's linked to higher risk of stroke

Here's yet another reason to stop smoking (or better yet, never start). Researchers found that secondhand smoke is linked to higher risk of stroke:

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.

"Second-hand smoke is a risk to all people, but those with a history of stroke should take extra care to avoid it," said lead author Dr. Michelle Lin of the Johns Hopkins School of Medicine in Baltimore.

One in four nonsmokers (58 million people) in the U.S. are still exposed to secondhand smoke, according to the Centers for Disease Control and Prevention.

Smoking is a known increase of stroke risk. I'd love to see that number of smokers to go down to zero.
