The findings have been corroborated by Public Health Foundation of India (PHFI) researchers who found that nearly two-thirds (64 percent) of adults who worked in smoke-free environments also lived in smoke free homes compared to just 42 percent of those who work in places where smoking is allowed.
"This may be the first signal from India that the ban on public smoking has a spill-over effect at home. The ban may be changing social norms. People seem to be saying to themselves — if we can't expose our colleagues to second-hand smoke, why should we expose our families?", Imperial College London's Christopher Millet said.
The study has been published in the journal Tobacco Control.
