Randomized Controlled Trial Multicenter Study
Gender differences in a randomized controlled trial treating tobacco use among adolescents and young adults with mental health concerns.
Treatment of tobacco use in mental health settings is rare despite high rates of comorbidity. With a focus on early intervention, we evaluated a tobacco treatment intervention among adolescents and young adults recruited from outpatient, school-based, and residential mental health settings and tested for gender differences. ⋯ Adolescent and young adult smokers with mental health concerns are a challenging group to engage and to effectively treat for tobacco addiction, particularly heavier smokers and boys. Innovative approaches are needed.

Several states implemented comprehensive smoke-free laws in workplaces (14 states), restaurants (17 states), and bars (13 states) between 2002 and 2007. We tested the hypothesis that public support for smoke-free laws increases at a higher rate in states that implemented smoke-free laws between 2002 and 2007 (group A) than in states that implemented smoke-free laws after that time or not at all (group B). The period before the implementation (1992-2001) was also considered. ⋯ The positive association between the implementation of smoke-free restaurant and bar laws and the rate of increase in support for these laws partly supported the hypothesis. The implementation of the laws may have caused support to increase, but also states that have higher support may have been more likely to implement smoke-free laws.

U.S. adolescents increasingly use e-cigarettes. The perceived harm of e-cigarettes has not been described, nor has the correlation between harm perception and e-cigarette use been assessed. This study examines correlates of e-cigarette harm perception and use of e-cigarettes in a national survey. ⋯ Perception of e-cigarettes as less harmful than conventional cigarettes was associated with increased e-cigarette use, including among cigarette-naive e-cigarette users. These findings should prompt further scientific investigation and merit attention from regulators.

Increasingly popular electronic cigarettes (e-cigarettes) may be the most promising development yet to end cigarette smoking. However, there is sparse evidence that their use promotes cessation. We investigated whether e-cigarette use increases smoking cessation and/or has a deleterious effect on quitting smoking and motivation to quit. ⋯ Daily use of electronic cigarettes for at least 1 month is strongly associated with quitting smoking at follow-up. Further investigation of the underlying reasons for intensive versus intermittent use will help shed light on the mechanisms underlying the associations between e-cigarette use, motivation to quit, and smoking cessation.

Electronic cigarettes (e-cigs) are becoming increasingly popular, but little is known about their dependence potential. This study aimed to assess ratings of dependence on electronic cigarettes and retrospectively compare them with rated dependence on tobacco cigarettes among a large sample of ex-smokers who switched to e-cigs. ⋯ Current e-cigarette users reported being less dependent on e-cigarettes than they retrospectively reported having been dependent on cigarettes prior to switching. E-cig dependence appears to vary by product characteristics and liquid nicotine concentration, and it may increase over time.
