- Increase the buildup of plaque in blood vessels

Breathing secondhand smoke can cause coronary heart disease, including heart attack and stroke. I've already told you about my mother. And my father smoked cigars. I was doomed. Here are the highlights:
- Each year, second-hand smoke exposure causes more than 8,000 deaths from stroke.
- Nonsmokers who breathe second-hand smoke at home or at work increase their risk of developing heart disease by 25–30%.
- Second-hand smoke increases the risk for stroke by 20−30%.
- Even briefly breathing secondhand smoke can damage the lining of blood vessels and cause your blood to dangerously thicken.
