SOME LONG TERM EFFECTS,,,

Tar in cigarettes coats the lungs and can cause lung and throat cancer in smokers. It is also responsible for the yellow–brown staining on smokers’ fingers and teeth.

Carbon monoxide in cigarettes reduces the amount of oxygen available to the muscles, brain and blood. This means the whole body—especially the heart—must work harder. Over time this causes airways to narrow and blood pressure to rise, which can lead to heart attack and stroke.

High levels of CO, together with nicotine, increase the risk of heart disease, hardening of the arteries and other circulatory problems.
