Longitudinal associations between use and co-use of cigars and cigarettes: A pooled analysis of three adolescent cohorts.

ABSTRACT: INTRODUCTION:Patterns of adolescent tobacco product use are evolving rapidly and need examination. We assessed whether ever use of cigars (i.e., lifetime use) was related to an increased risk of subsequent cigarette initiation and dual use of cigars and cigarettes. METHODS:Leveraging data from three prospective cohort studies of adolescents (n?=?6258), we assessed the odds of initiating cigarettes at one-year follow-up among ever cigar users at baseline, relative to never cigar users, after adjusting for demographics and e-cigarette use. We also assessed patterns of transition between exclusive use of cigars, exclusive use of cigarettes, and dual use of both cigars and cigarettes between baseline and follow-up and whether these associations differed by e-cigarette use. RESULTS:Among never cigarette smokers (n?=?4876; 79.3% of the total sample), 3.4% reported ever cigar use by baseline. Ever cigar use by baseline was associated with higher likelihood of initiating cigarettes by follow-up (31.3%) relative to never cigar use at baseline (8.4%; adjusted odds ratio?=?2.26, 95% confidence interval: 1.52, 3.35). Effect estimates were stronger if e-cigarette was used by baseline. Furthermore, exclusive ever cigar use by baseline was associated with a 2-4-fold increase in the odds of transition to exclusive cigar, exclusive cigarette, and dual use at follow-up relative to non-users of either product by baseline. CONCLUSIONS:Comprehensive tobacco regulations and early prevention efforts focused on reducing youth appeal of cigars may be warranted, as cigar use may place youth at risk for subsequent cigarette use as well as dual use of cigars and cigarettes.

Project description:AIMS:This study tested whether adolescents who used cannabis or met criteria for cannabis dependence showed neuropsychological impairment prior to cannabis initiation and neuropsychological decline from before to after cannabis initiation. DESIGN:A longitudinal co-twin control study. SETTING AND PARTICIPANTS:Participants were 1989 twins from the Environmental Risk (E-Risk) Longitudinal Twin Study, a nationally representative birth cohort of twins born in England and Wales from 1994 to 1995. MEASUREMENTS:Frequency of cannabis use and cannabis dependence were assessed at age 18. Intelligence quotient (IQ) was obtained at ages 5, 12 and 18. Executive functions were assessed at age 18. FINDINGS:Compared with adolescents who did not use cannabis, adolescents who used cannabis had lower IQ in childhood prior to cannabis initiation and lower IQ at age 18, but there was little evidence that cannabis use was associated with IQ decline from ages 12-18. For example, adolescents with cannabis dependence had age 12 and age 18 IQ scores that were 5.61 (t = -3.11, P = 0.002) and 7.34 IQ points (t = -5.27, P < 0.001) lower than adolescents without cannabis dependence, but adolescents with cannabis dependence did not show greater IQ decline from age 12-18 (t = -1.27, P = 0.20). Moreover, adolescents who used cannabis had poorer executive functions at age 18 than adolescents who did not use cannabis, but these associations were generally not apparent within twin pairs. For example, twins who used cannabis more frequently than their co-twin performed similarly to their co-twin on five of six executive function tests (Ps > 0.10). The one exception was that twins who used cannabis more frequently than their co-twin performed worse on one working memory test (Spatial Span reversed; ? = -0.07, P = 0.036). CONCLUSIONS:Short-term cannabis use in adolescence does not appear to cause IQ decline or impair executive functions, even when cannabis use reaches the level of dependence. Family background factors explain why adolescent cannabis users perform worse on IQ and executive function tests.

Project description:IntroductionPain has been implicated in the onset and maintenance of nicotine addiction, and there is initial cross-sectional evidence of covariation between pain and the use of cigarettes and e-cigarettes. The goals of the current study were to: (1)test pain severity as a predictor of initiating co-use of cigarettes and e-cigarettes, (2)examine longitudinal associations between pain and use/co-use of cigarettes and e-cigarettes, (3)generate the first prevalence rate data regarding cigarette and e-cigarette use as a function of pain, and (4)examine gender as a moderator of these associations.Aims and methodsData were drawn from Waves 1-4 of the Population Assessment of Tobacco and Health Study (2013-2018).ResultsAmong exclusive cigarette smokers at Wave 1 (n = 7719), pain severity was associated with a greater likelihood of and faster trajectory to initiating co-use of cigarettes and e-cigarettes (ps < .05). A significant pain × gender interaction (p < .05) revealed this prospective relationship was stronger among women. Among adult respondents who provided at least three waves of data (n = 24 255), greater Wave 1 pain severity was positively associated with e-cigarette use, cigarette smoking, and co-use of cigarettes and e-cigarettes at Waves 2, 3, and 4 (ps < .001). At Wave 4 (n = 33 822), adults with moderate or severe pain endorsed rates of e-cigarette and cigarette use almost two times greater versus no or low pain (ps < .001).ConclusionsCollectively, these findings provide evidence that pain likely serves as an important candidate risk factor for the initiation and maintenance of cigarette and e-cigarette use.ImplicationsThis is the first prospective study to show that pain serves as an important risk factor for initiation and maintenance of cigarette and e-cigarette use over time. Weighted prevalence estimates further demonstrated that individuals with moderate or severe pain endorsed rates of cigarette and e-cigarette use and co-use approximately two times greater compared to those with no or low pain. These findings highlight a subpopulation of nicotine users more susceptible to greater healthcare burden, nicotine dependence, and physical impairment. Nicotine users with comorbid pain may benefit from integrated interventions that address pain in the context of cessation.

Project description:IntroductionThis study assessed the association of exclusive and concurrent use of cigarettes, electronic nicotine delivery systems (ENDS), and cigars with ever and past 12-month wheezing symptoms among a nationally representative sample of US adult current tobacco users.MethodsCross-sectional data from the Population Assessment of Tobacco and Health (PATH) Study Wave 3 (W3) were used. The weighted prevalence of self-reported ever and past 12-month wheezing symptoms for noncurrent users compared with users of cigarettes, ENDS, cigars, and any combination of these products (polytobacco use of these tobacco products) were presented for 28 082 adults. The cross-sectional association of tobacco use with self-reported wheezing symptoms was assessed using weighted multivariable and ordinal logistic regression with consideration of complex sampling design.ResultsSignificantly higher odds of ever had wheezing or whistling in the chest at any time in the past were observed among current cigarette (adjusted odds ratio: 2.62, 95% confidence intervals [CI]: 2.35, 2.91), ENDS (1.49, 95% CI: 1.14, 1.95), and polytobacco users (2.67, 95% CI: 2.26, 3.16) compared with noncurrent users. No associations were seen for cigar use. Polytobacco use was associated with a higher odds of ever wheezing when compared with exclusive ENDS (1.61, 95% CI: 1.19, 2.17) and exclusive cigar use (2.87, 95% CI: 1.93, 4.26), but not exclusive use of cigarettes.ConclusionsEver wheezing is associated with the use of cigarettes, ENDS, and polytobacco use of cigarettes, ENDS, and/or cigars, but not cigar use. The association of polytobacco use and wheezing appears to be driven by cigarette use.ImplicationsCross-sectional associations with ever and past 12-month wheezing symptoms were found to be the strongest among cigarette users, exclusively or in combination. Future longitudinal research is needed to better understand how cigarette use interacts with other tobacco and nicotine products and contributes to respiratory symptoms.
