Different genes influence smoking risk during adolescence and adulthood (March 31, 2011) -- There is growing evidence that the risk factors for addiction change throughout the lifespan. The risk factors for developing addiction in adolescence are the most intensively studied because this life phase is associated with the highest addiction risk. Traits linked to addiction risk during adolescence include pleasure-seeking, behavioral disinhibition, and devaluation of the future negative consequences of behavior. In contrast, the development of substance use among adults is more commonly associated with high levels of stress, anxiety, and depression. ... > full story
