NIDA Researchers Identify Genetic Variant Linked to Nicotine Addiction and Lung Cancer 

Scientists have identified a genetic variant that not only makes smokers more susceptible to nicotine addiction but also increases their risk of developing two smoking-related diseases, lung cancer and peripheral arterial disease. The research was supported by the National Institute on Drug Abuse (NIDA), part of the National Institutes of Health (NIH).

The study, published in the April 3 issue of the journal Nature, "highlights the advances that are being made in genetics research, which can now identify gene variants that increase the risk of complex bio-behavioral disorders," says NIH Director Dr. Elias Zerhouni. "This finding will help us in our efforts to further reduce the scope and devastating consequences of cigarette smoking."
