A new study finds more than 40 percent of New Yorkers are exposed to secondhand smoke inside their home.
The Health Department released a new "Vital Signs" report on secondhand smoke exposure, and smoke-free housing policies in the city.
It found 44 percent of New Yorkers in 2016 were exposed to cigarette smoking while inside their homes.
Exposure was highest among black and Hispanic adults, and people living in high-poverty neighborhoods.
White and Asian residents had the lowest exposure rates.
