[Identifying addictive behaviors among adolescents: a school based survey]
French epidemiological data show that adolescents today experiment with tobacco at an earlier age than in the 1990s. Half of them combine tobacco consumption with other psychoactive products such as alcohol or cannabis. Tobacco consumption usually begins in adolescence and early smoking initiation is related to stronger nicotine dependence and problems quitting in adulthood. Occasional tobacco consumption rapidly leads to nicotine dependence. The national smoking cessation questionnaire is a tool to assess addictive behaviors among adolescents. It includes validated scales such as the loss of autonomy over tobacco and psychological evaluation. The aim of this school based study was to assess addictive behaviors among adolescents (specifically loss of autonomy over tobacco) and psychological profile. Data were collected from a cross sectional study conducted in a high school in the Paris metropolitan area (Nogent sur Marne) in 2007 by the smoking cessation team of the Albert Chenevier Hospital. Three hundred adolescents filled in a questionnaire concerning tobacco, alcohol, and cannabis consumption as well as their psychological profile. Loss of autonomy over tobacco use was evaluated with the Hooked on Nicotine Checklist (HONC) Anxiety and depressive disorders were identified using the Hospital Anxiety and Depression scale (HAD) Self administered questionnaires were anonymously completed in the classroom by 151 girls and 149 boys aged 15 16 years (mean, 15.4 years) 34% of the adolescents smoked and most of them smoked at least one cigarette a day; 38% had used cannabis at least once in their life and one third of them smoked more than 10 cannabis joints per month. Adolescents who frequently smoked cannabis had started smoking tobacco earlier than the other smokers (mean, 11.7 years versus 13.2 years) Adolescents often used different tobacco products. Manufactured cigarettes were the most frequently used, followed by shisha (waterpipe) and hand rolled cigarettes. Among those who only smoked shisha, 76% had declared being non smokers. Alcohol was the first psychoactive drug experimented by these adolescents; 73% had used alcohol at least once in their life and 10% used alcohol several times a week. According to the HONC, 94% of the smokers had lost control of their tobacco consumption. Concerning anxiety and depressive disorders, anxiety and depression scores were higher among smokers than non smokers. Less than 6% of never smokers had a depression score greater than 8 compared to 26% of adolescents smoking cannabis more than 10 times a month. The rapidity of the loss of autonomy among young smokers emphasizes the need for early interventions for tobacco prevention and cessation among adolescents. Tobacco use was often associated with anxiety and depressive symptoms, suggesting a need for professional support. The national smoking cessation questionnaire may be helpful in pediatric wards and consultations.
