What Are the Effects of Second Hand Smoke on the Lungs?

The effects of second hand smoke on the lungs may be just as serious as those affecting a person who smokes. People who are exposed to second hand smoke typically have an increased risk of lung cancer and various lung-related illnesses, such as asthma, bronchitis, and even tuberculosis. Many studies also show that while the effects of second hand smoke on the lungs are harmful to everyone, they may be especially dangerous for babies and small children. In most cases, children who live in the same home with smokers are much more likely to have frequent ear infections and illnesses such as pneumonia and bronchitis.
