Mortality associated with passive smoking in Hong Kong

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 Kong 2 and now present the related findings on passive smoking at home.
