Introduction Although adolescent cigarette use continues to decline in the United States, electronic cigarette (e-cigarette) use among adolescents has escalated rapidly. This study assessed trends and patterns of e-cigarette use and concurrent cigarette smoking and the relationships between e-cigarette use and smoking cessation intentions and behaviors among high school students in North Carolina. Methods Data came from high school students who completed the schoolbased, cross-sectional North Carolina Youth Tobacco Survey in 2011 (n = 4,791) and 2013 (n = 4,092). This study assessed changes in prevalence of e-cigarette and cigarette use from 2011 through 2013, and cessation-related factors associated with those students' current and past use of e-cigarettes in 2013. Results The prevalence of current e-cigarette use (use in the past 30 days) significantly increased from 1.7% (95% CI, 1.3%-2.2%) in 2011 to 7.7% (95% CI, 5.9%-10.0%) in 2013. Among dual users, current e-cigarette use was negatively associated with intention to quit cigarette smoking for good (relative risk ratio [RRR] = 0.51; 95% CI, 0.29-0.87) and with attempts to quit cigarette smoking in the past 12 months (RRR = 0.69; 95% CI, 0.49-0.97). Current ecigarette smokers were less likely than those who only smoked cigarettes to have ever abstained from cigarette smoking for 6 months (RRR = 0.42; 95% CI, 0.21-0.82) or 1 year (RRR = 0.21; 95% CI, 0.09-0.51) and to have used any kind of aids for smoking cessation (RRR = 0.46; 95% CI, 0.29-0.74). Conclusion Public health practitioners and cessation clinic service providers should educate adolescents about the risks of using any nicotinecontaining products, including e-cigarettes, and provide adequate tobacco cessation resources and counseling to adolescent tobacco users.
