Association of e-cigarette vaping and progression to heavier patterns of cigarette smoking
Menée aux Etats-Unis à partir d'enquêtes réalisées entre 2014 et 2015 auprès de 3 282 adolescents (âge moyen : 15,5 ans), cette étude analyse l'association entre l'utilisation de la cigarette électronique et la progression vers un tabagisme excessif
E-cigarette vaping is reported by 37% of US 10th-grade adolescents and is associated with subsequent initiation of combustible cigarette smoking. Whether individuals who vape and transition to combustible cigarettes are experimenting or progress to more frequent and heavy smoking is unknown. In addition, because some adolescents use e-cigarettes as a smoking cessation aid, adolescent smokers who vape could be more likely to reduce their smoking levels over time. Therefore, associations of vaping with subsequent smoking frequency and heaviness pattern among adolescents were examined.
