E-Cigarette Use in Adolescents and Adults—A JAMA Collection
Mené sur 1 503 adolescents américains utilisant la cigarette électronique (âge : 13-17 ans ; durée de suivi : 1 à 7 mois), cet essai randomisé évalue l'efficacité, du point de vue de l'abstinence autodéclarée, d'un programme automatisé et interactif par SMS pour l'arrêt du vapotage
The introduction of electronic cigarettes (e-cigarettes) in recent years has created new dilemmas for clinical and research communities. E-cigarettes are battery-powered devices that heat liquids containing nicotine, flavoring, and other substances to create aerosols. Their use is often called “vaping.” E-cigarettes have been marketed as safer alternatives to cigarettes because they do not contain the carcinogens found in combustible tobacco products. More than 4.5% of US adults, 10% of high school students, and 4.6% of middle school students report currently using e-cigarettes.The dilemmas from e-cigarettes arise from their contrasting benefits and risks. They may help current smokers quit conventional cigarettes, but their long-term effects are unknown, and they may serve as an entry point to nicotine addiction for nonsmokers, particularly adolescents. For adult smokers, a recent Cochrane review found high certainty that e-cigarettes produce higher quit rates than nicotine replacement therapy. However, the substitution of e-cigarettes as an aid to smoking cessation may lead to long-term use of the e-cigarettes themselves. For nonsmokers, e-cigarettes hold no benefits, and they may increase the risk of nicotine addiction for adolescents, in part because they are more appealing and easily concealed than cigarettes.
