Joint lead author Prof Sir Mike Stratton, from the Wellcome Trust Sanger Institute, said:"The more mutations there are, the higher the chance that these will occur in the key genes that we call cancer genes, which convert a normal cell into a cancer cell."

It is not only bad for your health is bad for your genetic make up.

Tobacco smoking damages DNA in organs directly exposed to smoke as well as speeds up a mutational cellular clock in organs that are both directly and indirectly exposed to smoke." said Ludmil Alexandrov of the Los Alamos National Laboratory in Los Alamos, New Mexico, who led the study.

People who smoke a pack of cigarettes each day for a year develop on average 150 extra mutations in every lung cell, and nearly 100 more mutations than usual in each cell of the voice box, researchers found.

I am sure it causes all kinds of things. People still will not give them up. This wI'll go down in history as the most addictive substance in history.
