Second-hand smoke dangerous to kids' grades

Second-hand smoke is despicable any way you slice it (although I've heard vehement disagreements to that statement), but let's go beyond the standard health issues it can cause non-smokers, shall we?

A new study finds that second-hand smoke also affects the test scores of non-smoking teens. Sounds weird, right? Research out of Temple University states that those in the 16-18 age bracket that were exposed to second-hand smoke were 30 percent less likely to pass standardized tests compared to their peers.

Now, I'm not sure how the researchers observed exposure to second-hand smoke in the lives of these kids outside of a survey, but the results are interesting nonetheless. There is a growing body of evidence that suggests second-hand smoke does indeed affect test scores, so this study can be added to that list now.
