A new report from the United States Surgeon General says there is no risk-free level to second hand smoke.
According to the report the only way to protect non-smokers from the health risks of second hand smoke is to eliminate smoking in buildings.
An idea many local people are already considering.
"Many people think that if they can't smell it then, they're ok. But the report shows separating them or ventilating can not accomplish that," Coordinator for Tobacco Free in Eau Claire Julie Marlette says.
The report also states that young children exposed are at an increased level to suffer SIDS or other severe respiratory diseases.
