Researchers at the Harvard University are reporting that
partners of smokers are at a greater risk of suffering a stroke by inhaling
second hand smoke.
The study involved more than 16,000 people aged over 50 and followed them for nine years at an average. The study found that non-smokers who had a smoking partner had a 42 percent increased risk of suffering a stroke.
The risk increased to 72 percent if the non-smoker started smoking as well.
