About Tar in Cigarettes

Above some info about tar in cigarettes.

Tar in lungs is not the same tar that is used to manufacture tires or build roads. It is a sticky, dark brown chemical that is produced when tobacco is burned through smoking. Tar can damage the lungs and can stain teeth, fingers and clothing.

Inhalation

The tar enters the lungs when the smoke is inhaled. The more a smoker smokes, the more tar he will inhale. When a smoker inhales the smoke from the cigarette, that dark tar is also inhaled into the lungs. When cigarette smoke is inhaled, it condenses and deposits cigarette tar in the lungs. The more a smoker smokes, the more tar that will coat his lungs. It will eventually interfere with the smoker's breathing.
