Previous studies have demonstrated the influence of parental (both mother and father) cigarette smoking on adolescents' cigarette smoking. Little is known, however, about how parental tobacco use is related to waterpipe and dual waterpipe/cigarette use, which is increasing dramatically in the Arab countries. ⋯ (1) Influence of parents' cigarette smoking on adolescents' smoking has been demonstrated in earlier studies, however, little is known about how tobacco use behaviors of mother and father influences an adolescent's cigarette, waterpipe and dual cigarette/waterpipe use. (2) Associations of parental (both mother and father) tobacco use with adolescents' tobacco use differed significantly if the adolescent is a waterpipe smoker or dual user compared to an adolescent cigarette smoker. (3) Adolescents' exposed to their mothers' WPS or dual use were more likely to be a waterpipe smoker or dual user. High likelihood of adolescents' cigarette, waterpipe and dual use is found in homes where parental tobacco use is rampant with both parents smoking either cigarette, waterpipe or both.

In high-income countries, secondhand smoke (SHS) exposure is higher among disadvantaged groups. We examine socioeconomic inequalities in SHS exposure at home and at workplace in 15 low- and middle-income countries (LMICs). ⋯ SHS exposure is higher among the socioeconomically disadvantaged groups in high-income countries. Comprehensive smoke-free policies are pro-equity for certain health outcomes that are strongly influenced by SHS exposure. Using nationally representative Global Adult Tobacco Survey (2008-2011) data from 15 LMICs, we studied socioeconomic inequalities in SHS exposure at homes and at workplaces. The study showed that in most LMICs, SHS exposure at homes is higher among the poor and the less educated. At workplaces, SHS exposure is higher among the less educated groups. Accelerating implementation of pro-equity tobacco control interventions and strengthening of efforts targeted at the socioeconomically disadvantaged groups are needed to reduce inequalities in SHS exposure in LMICs.

This study seeks to determine whether comprehensive quitline services combined with text messaging improve smoking cessation rates beyond those achieved by offering comprehensive quitline services alone. ⋯ While the impact of quitline and text messaging services for smoking cessation have been examined in isolation, no study has explored the impact of combined services on smoking outcomes. This study examines the role of text messaging in combination with comprehensive quitline services including multi-call phone counseling, access to an interactive website and nicotine replacement therapy.

Electronic cigarettes (ECIGs) aerosolize a liquid that usually contains propylene glycol and/or vegetable glycerin, flavorants, and the dependence-producing drug nicotine in various concentrations. This study examined the extent to which ECIG liquid nicotine concentration is related to user plasma nicotine concentration in ECIG-naïve tobacco cigarette smokers. ⋯ Liquid nicotine concentration can influence plasma nicotine concentration in ECIG-naïve cigarette smokers, and, at some concentrations, the nicotine delivery profile of a 3.3V ECIG with a dual coil, 1.5-Ohm cartomizer approaches that of a combustible tobacco cigarette in this population. Finding a product that delivers nicotine as effectively as a tobacco cigarette, as we report here, may be essential for smokers who want to replace completely their combustible tobacco cigarettes with ECIGs.

The popularity of electronic cigarettes (e-cigarettes) among adolescents is growing worldwide. A more accurate model than the much discussed but inadequate Gateway Hypothesis is needed to explain some adolescents' initial preference for e-cigarettes over tobacco cigarettes, as well as any transition from e-cigarettes to tobacco smoking. Our aim was to summarize the diffuse fear that adolescents will be indirectly encouraged to begin smoking tobacco via the use of e-cigarettes and to systematize the disparate causal hypotheses used thus far in relevant literature. ⋯ We developed a model that provides causal hypotheses for the initiation of e-cigarette use and for the potential transition to tobacco smoking.
