Collectively, the evidence favoring the sequence of steps [that result in smoking causing cancer] is extremely strong, although there are important aspects of each step that require further study. These include carcinogen metabolism and DNA binding in human lung, the effects of cigarette smoke on DNA repair and adduct persistence, the relationship between specific carcinogens and mutations in critical genes, and the sequence of gene changes leading to lung cancer.

...the health effects of smoking provides a startling picture of the damage to health caused by tobacco use. Smoking injures almost all bodily organs, and tragically this injury often leads to incurable disease and death. The comprehensive review process that is the foundation of this series of reports has found new causal associations of smoking with disease, reemphasizing the need for continued monitoring of scientific evidence on the health effects of smoking.
