Secondhand smoke is smoke that people inhale from being around others who are smoking tobacco products like cigarettes. It’s long been known that exposure to such smoke is harmful. That’s why laws have been put into effect that ban the use of such products in indoor public places. But do these laws actually work? After Scotland issued an indoor smoke-free law, non-smoking bar workers experienced fewer respiratory problems, like coughing and wheezing, within two months. In Ireland, the same law led to better lung function for the same workers. And in New York, a state smoke-free workplace law was linked to 8% fewer hospital stays due to heart attacks. This led to a savings of $56 million in hospital costs.
