A large-scale study has found no clear link between secondhand tobacco-smoke exposure and lung cancer, undercutting the premise of years of litigation including a Florida case that yielded a $350 million settlement, according to a story by Daniel Fisher for Forbes.
Fisher cites an article in the Journal of the National Cancer Institute that provides the results of a study of 76,000 women over more than a decade.
The study found a link between smoking and cancer, with lung cancer 13 times more common among current smokers and four times more common in former smokers than in nonsmokers.
But the study found no statistically significant relationship between lung cancer and exposure to passive smoke.
