Secondhand Smoke How Deadly Is It?

Nonsmoking adults who live with a smoker have a 15% greater risk of dying. This frightening fact is based upon census data from the entire population of New Zealand.

Perspective: This is the largest study to examine the risk of mortality in secondhand smokers. Its findings are consistent with previous smaller studies, but because of its larger size the results have a higher degree of statistical accuracy. This adds considerable weight to the existing evidence of harm caused by exposure to secondhand smoke.

Comment: Here we have more evidence for the dangers of secondhand smoke (as if we needed more evidence).
