If you have a smoker in the home, chances are you have this air pollutant as well. Whether it comes from a cigarette, pipe, cigar, or the exhale of a smoker, tobacco smoke contains at least 40 compounds that are known to cause cancer.
Besides cancer, children who are exposed to tobacco smoke have an increased risk of lower respiratory tract infections, like pneumonia and bronchitis, asthma, and respiratory irritations, like coughing, wheezing, and excess phlegm. They also have an increased risks of SIDS. It may also cause a build-up of fluids in the middle ear, leading to ear infections.
As an adult, being exposed to cigarette smoke for 4 hours or more per day can make your real age as much as 6.9 years older.
