Secondhand Smoke

Secondhand smoke, the combination of smoke from the burning end of a cigarette and the smoke breathed out by smokers, is harmful to everyone. Secondhand smoke contains more than 7,000 chemicals, hundreds of which are toxic and about 70 of which can cause cancer. There is no safe or risk-free level of exposure to secondhand smoke.

How Secondhand Smoke Impacts Health

Secondhand smoke causes numerous health problems in infants and children, including severe asthma attacks, respiratory infections, ear infections, and sudden infant death syndrome (SIDS). Some of the health conditions caused by secondhand smoke in adults include heart disease and lung cancer.

Exposure to secondhand smoke is a contributor to pediatric asthma, a major problem among Denver’s children. Because of the frequency of tobacco use and exposure to secondhand smoke and the breadth of the resulting serious health problems, decreasing tobacco use and exposure is the single most powerful tool we have to improve health in Denver.
