Due to these changes, people exposed to secondhand smoke have a 20 to 30 percent increased chance of having a stroke. They also boost their risk of heart disease by 25 to 30 percent.

Nonsmokers who expose themselves to cigarette smoke at home or work increase their risk of developing lung cancer by 20 to 30 percent, states the CDC. Secondhand smoke causes approximately 7,300 annual lung cancer deaths in the United States.
