Elucidating the role of genetic factors in smoking behavior and nicotine dependence.
Despite over a decade of intensive tobacco control efforts, a substantial proportion of the world's population continues to smoke. With advances in molecular biology and genomics technology, attention is focusing on the genetic basis of addiction to nicotine. The hope is that by better understanding the biology of nicotine addiction, novel prevention and cessation strategies can be developed and targeted to individuals most likely to benefit. This article provides an overview of currently available data from genetics research on smoking behavior and discusses study design issues to be addressed to make progress in this line of research.
