Cigarette tar also damages cilia in the lungs, which protect the lining of the lungs. In addition to the discoloring of teeth, tar can cause periodontitis, a gum disease that can result in the loss of teeth.
The nicotine is the addictive substance, however it is the tar within the cigarette which is harmful to the human body. This tar sufficiently reduced the surface area of the alveoli to perform gas exchange. This black tar fills up and blocks the lungs making it harder for the smoker to breathe - causing breathlessness. This tar build up also leads to heart diseases and such.

Each puff of a cigarette adds another layer of carcinogenic tar onto the lungs sensitive tissue, making it harder for the underlying alveoli-sacs to perform their task of absorbing oxygen and excreting carbon dioxide.
