    I am a physician, and also interested in passive smoking problem. I think this article has a unique viewpoint on risk communication about environmental pollution.

    But I should point out that he underestimated the risk associated with passive smoking. There are some recent articles(1,2) concerning the lifetime all-cause mortality due to passive smoking, suggesting that 10~30% of nonsmokers exposed to environmental tobacco smoke at home will be dead prematurely.
