Secondhand Smoke Damages Lungs

Researchers say they now have evidence that long-term exposure to secondhand smoke can cause structural damage in the lungs that is indicative of emphysema. The study, which was presented at the annual meeting of the Radiological Society of North America, used a modified MRI technique to detect lung damage. The test detected signs of early lung damage in 67% of smokers and 27% of nonsmokers with heavy exposure to secondhand smoke. In contrast, only 4% of nonsmokers who had never smoked and had fewer than 10 years of exposure appeared to have signs of early lung damage, researchers say.
