Project Title: Nicotine Metabolism and the Development of Addiction in Adolescent Light Smokers
Fiscal Year: 2009


Abstract

DESCRIPTION (provided by applicant): Studies have shown that adult smokers with the presence of certain genetic markers associated with slower nicotine metabolism smoke fewer cigarettes and are more likely to quit. Although it seems likely that nicotine metabolism affects the degree of nicotine dependence in smokers, the impact on the development of nicotine dependence is less clear. Since addiction most frequently occurs during adolescence, prospective studies that focus on smoking during this time period are essential to give us information on the effects of nicotine metabolism on the progression to addiction. Objective: To ascertain whether the rate of nicotine metabolism affects adolescents' susceptibility to nicotine addiction. Specific aims: We will examine the association between the rate of nicotine metabolism and cigarette consumption over time in a prospective cohort of adolescent early/experimental smokers (Aim 1). We will also examine the association between the rate of nicotine metabolism and the development of addiction in adolescent early/experimental smokers (Aim 2). Study design: Using a prospective cohort design, we will examine the influence of the rate of nicotine metabolism (measured by the 3'-hydroxycotinine/cotinine ratio) on the development of nicotine addiction in adolescent early/experimental smokers (13-16 years-old who smoke 1-14 cigarettes per week). At baseline, smoking behavior and addiction questionnaires will be administered and saliva samples will be obtained for determination of nicotine metabolic rate. All subjects will then be seen at 6 month intervals up to 36 months. Addiction will be measured by increasing salivary cotinine levels reflecting increased intake and the development of nicotine addiction signs and symptoms using standardized scales. Significance: The proposed research is critical to understanding why and how some adolescent smokers make the transition from experimentation to addicted smoker. Although only a small percentage of teens smoke cigarettes, we know that those who continue smoking into adulthood are more likely to smoke heavily, less likely to quit and given the cumulative effect of smoking related toxins, are at increased risk for developing negative outcomes from smoking. Therefore, intervening early among adolescent smokers is essential to halt the devastating effects from smoking. Moreover, as studies of adult smokers have suggested that response to pharmacotherapy for smoking cessation may be influenced by a smoker's individual rate of nicotine metabolism, the metabolic rate may prove equally useful when choosing specific forms of nicotine replacement for adolescents. Therefore, research into the effect of nicotine metabolism on adolescent smokers may provide new and important insights into which teens may benefit from nicotine replacement and which may be more likely to benefit from non-nicotine pharmacotherapy or non- pharmacologic interventions. PUBLIC HEALTH RELEVANCE: Data derived from this study will provide us with essential information about why and how some adolescent smokers make the transition from experimentation to addicted smoker. As we better understand adolescent nicotine addiction, we can improve prevention and treatment strategies for adolescent smokers and thus prevent the multitude of preventable cancers associated with tobacco use.
