How severely can breathing secondhand smoke age me?

Dr. Mehmet Oz, MD
Cardiologist (Heart Specialist)
Cigarette smoke can harm you the very second you inhale. And you don't have to wrap your lips around a cigarette to be exposed. You may not see or even smell cigarette smoke because it can waft through the air unnoticed. But if you and your children live with a smoker, you are exposed to secondhand smoke. It can have an immediate harmful effect on the lining of the blood vessels, including those supplying the heart and the lungs. There is no safe level of secondhand smoke. The damage from secondhand smoke is similar to the damage from directly inhaling smoke. It can shave years off your life and cause you to develop serious diseases.
Dr. Jeanne Morrison, PhD
Family Practitioner
Cigarette smoke contains more than 7,000 chemicals including hundreds that are toxic and 70 that cause cancer. Repeated exposure to secondhand smoke increases your risk of heart disease and lung cancer by 25% to 30%. More than 46,000 nonsmokers die of heart disease because of secondhand smoke.
