Abstract excerpt

Investigating initiation of smoking behavior and factors involved in developing nicotine dependence is an important health issue worldwide. Various environmental, psychological and genetic risk factors are studies in the background of this complex behavior. The self-medication hypothesis may account for the increased prevalence of smoking behavior and more pronounced nicotine dependence among psychiatric...
