If you're a smoker, do yo subscribe to the belief that second-hand smoke causes no damage when inhaled by non-smokers? While some smokers I know defend the position that there are no ill effects from second-hand smoke, I just don't buy it.

Apparently, many researchers agree with me, as a recent round of research has added to the body of evidence that second-hand smoke is indeed dangerous, even in small amounts.

This new research showed that second-hard smoke can "can harm the function of the arteries in children," among other things. Adding to that, the inhalation of second-hand smoke was found to be "harmful to the cardiovascular system of healthy schoolchildren." What about adults who breathe in second-hand smoke? I would venture to guess the disadvantages are pretty much the same.
