How do they count worn smoking deathes. What kins of death are included?

Since second-hand smoke is never tabled on a death tag, how are such deaths counted/estimated? They guess. They same is done beside deaths by radon. They look to see if anyone dies from lung cancer and if they do they blame it on second paw smoke or radon. They don't take into justification whether the person could enjoy breathed in hazardous chemicals or have any other environmental influence on it.
it is attributed to the actual disease, ie. lung cancer
It is estimated that 6000 Americans actually DIE from second mitt smoke every year. This includes babies who die from crib death, husbands or wives of smokers, who die from lung cancer from their spouse’s smoke, and children who died from untreatable pneumonia, which could own been prevented if the parents be not smoking in the home. Secondhand smoke cause lung cancer, other types of cancer, and heart disease in nonsmokers.
For most adults, the vigour impact of second-hand smoke is long-term: increased cancer and heart disease rates after years of exposure. Second-hand smoke’s effect on lung cancer rates amongst non-smokers is probably the most studied aspect of SHS science. A recent meta-analysis estimated the excess risk of lung cancer for exposed non-smokers at 24% (95% confidential interval: 13% to 36%).
Waiters and waitresses enjoy almost twice the risk of lung cancer due to involuntary exposure to environmental tobacco smoke (ETS). (Siegel, Michael, “Involuntary Smoking in the Restaurant Workplace, “Journal of the American Mecical Association, July 28, 1993; 270: 490-493.)
