In 2008-2009, we conducted a 6-week, open-label trial of transdermal nicotine replacement therapy and practical counseling for 34 adolescents seeking smoking cessation in Los Angeles. Dependent outcomes were study retention, use of the patch, and 7-day quit status at the end-of-study and at follow-up visits. Predictors of outcomes included cigarette dependence, withdrawal symptoms, demographic and psychiatric measures, and other substance use. Variables significant in bivariate analysis (p < .10) were retained in a multivariate model. Subjects had significant pre-to-post reductions in quit rates, dependence, and withdrawal symptoms. Subjects also reported a high number of comorbidities. Implications for clinicians are discussed.
