"3.Smoking cigarettes with lower machine-measured yields of tar and nicotine provides no clear benefit to health."
p 6 Executive Summary

Harmful Effects of Tobacco Combustion

Cigarette manufacturers make their cigarettes so that the tobacco will smolder and not light up like a bon fire. They keep the tobacco moisture level high enough, and wrap the cigarette tightly enough to keep the tobacco smoldering rather than burning with a large flame.

The result is cigarette tar.

Composed of the solid matter that is not completely burned but carried in the smoke, the tar carries most of the chemicals in cigarettes that cause cellular damage and lead to cancer and tumour formation.

At the higher temperatures in a cigarette the tar is melted and almost "dissolved" in the smoke, but in your body it becomes solid again and causes a lot of the characteristic staining such as nicotine stains on the fingers of heavy smokers or yellow smoker's teeth.
