Secondhand Smoke at Home Leads to Increased Risk of Emphysema
Researchers reported in late December that children regularly exposed to secondhand tobacco smoke at home are more likely to develop emphysema in adulthood. Scientists at Columbia University's Mailman School of Public Health looked at CT scans of 1,781 nonsmoking adults and their smoke exposure during childhood. The adults with more exposure showed more emphysema-like lung changes in the scans.
"The key finding is that some effects of tobacco exposure on the lungs may persist for decades," Gina Lovasi, the study's lead researcher, tells ParentDish via e-mail. "This contradicts the idea that a child's lungs will recover quickly and completely once exposure stops."
The point? This is yet another reason to keep cigarette exposure away from children. Or, better yet, if you're a smoker, inspiration to kick the habit for good.
