Mortality associated with passive smoking in Hong Kong

Mortality associated with passive smoking in Hong Kong -- McGhee et al. 330 (7486): 287 -- BMJ
Passive smoking can cause death from lung cancer and coronary heart disease, but there is little evidence for associations with other causes of death in never smokers. A recent study showed increased all cause mortality with exposure to secondhand smoke at home but did not examine associations with specific causes of death and dose-response relations.1 We have published estimates of the mortality attributable to active smoking in Hong Kong2 and now present the related findings on passive smoking at home.
