Secondhand smoke, also known as environmental tobacco smoke, passive smoke, and tobacco smoke polution is a mixture of the smoke exhaled by a smoker and smoke from the lit end of a cigarette, cigar, or pipe. It contains more than 7,000 chemicals1 including at least 70 known carcinogens1 (cancer causing substances). People exposed to secondhand smoke are at increased risk for many negative health conditions. A child who spends an hour in a room filled with secondhand smoke breathes in as many harmful chemicals as a person who smokes 10 or more cigarettes.

What are the Dangers? 

Adults

In nonsmoking adults, secondhand smoke:

  • Can cause lung cancer
  • Can cause cardiovascular disease, including heart attack and stroke.
  • Is associated with chronic lung conditions such as asthma and bronchitis

Children

Because of their developing lungs, children are especially vulnerable to secondhand smoke. It is estimated that more than 50% of the world's children are exposed to secondhand smoke in their own homes. A child who spends an hour in a room filled with secondhand smoke breathes in as many harmful chemicals as a person who smokes 10 or more cigarettes.

Secondhand smoke may increase:

  • An infant's risk for low birthweight if mother is exposed to secondhand smoke during pregnancy
  • An infant's risk for sudden infant death syndrome (SIDS)
  • Risk of severe infections of the lower respiratory tract, such as bronchitis and pneumonia
  • Risk of developing asthma
  • Risk of ear infections

Common Health Problems Caused by Secondhand Smoke

  • Cavities
  • Reduced lung function
  • Sore throat
  • Coughing and wheezing
