Secondhand smoke is more than just a nuisance; it is harmful to those who breathe it. It has about 4,000 chemicals, 69 of which contain known or suspected carcinogens. We’re talking chemicals like benzene and formaldehyde.
But don’t take our word for it. Check out what the health experts have to say:
The U.S. Surgeon General did a comprehensive overview of the effects of secondhand smoke exposure
The Institute of Medicine studied on the effects of secondhand smoke on the cardiovascular system.
The U.S. Centers for Disease Control and Prevention studied what happened to the heart attack rate in Pueblo, Colorado, after that city went smokefree.
The National Cancer Institute also studied the health harms of secondhand smoke.
In addition, the Campaign for Tobacco-Free Kids has a lot of good fact sheets about the dangers of secondhand smoke, the effect of smokefree laws on restaurant and bar business (it is good), a list of chemicals in secondhand smoke, reasons that ventilation doesn’t work (it takes smell out of the air but not the toxins) and more.
