E-cigarette Use Among Young Adults in the U.S.

ABSTRACT:

Introduction

Use of e-cigarettes is increasing among young adults in the U.S. Whether e-cigarette use serves as an aid to smoking reduction or cessation among young adults remains a matter of contention. This analysis examines patterns of e-cigarette use in relation to cigarette smoking in a nationally representative sample of U.S. young adults.

Methods

Data were analyzed from nationally representative U.S. adults, aged 18 to 35years (N=12,415), in the 2012-2013 National Epidemiologic Survey on Alcohol and Related Conditions-III. Logistic regression assessed associations between e-cigarette use and smoking intensity, continuity, and reduction while controlling for several potential confounding factors. Data were analyzed in 2018.

Results

Among cigarette smokers, e-cigarette use was associated with higher odds of tobacco use disorder (AOR=2.58, 95% CI=1.73, 3.83) and daily cigarette smoking (AOR=1.67, 95% CI=1.73, 3.83). Among adults aged 26-35years, e-cigarette use was also associated with heavy cigarette smoking (AOR=2.01, 95% CI=1.09, 3.74). Among lifetime smokers, e-cigarette use was associated with lower odds of stopping smoking (AOR=0.14, 95% CI=0.08, 0.23) and lower odds of a 50% reduction in cigarettes smoked per day (AOR=0.63, 95% CI=0.43, 0.93). Only 13.1% of young adults who ever used e-cigarettes reported using them to help stop or quit smoking.

Conclusions

Use of e-cigarettes by U.S. young adults, most of which is not intended to help reduce smoking, is related to more rather than less frequent and intensive cigarette smoking.

Project description:Background'Ice' e-cigarette flavours-marketed as a combination of fruity/sweet and cooling flavours (eg, 'blueberry ice' or 'melon ice')-recently entered the US market. The prevalence and correlates of ice flavoured e-cigarette use in young adults are unknown.MethodsThis cross-sectional study of a Los Angeles, California, USA, cohort analysed data from the past 30-day e-cigarette (current) users (n=344; M (SD)=21.2 (0.4) years old) who completed web-based surveys from May-August 2020. The exposure variable was self-reported e-cigarette flavour used most often in the past month (menthol/mint, fruit/sweet or ice). Outcomes included self-reported combustible tobacco use, vaping dependence symptoms, frequency of use and device type used.ResultsAmong current e-cigarette users, 48.8% reported using ice flavours most often, 33.7% predominately used fruit/sweet and 17.4% used menthol/mint. Using primarily ice-flavour was associated with reporting more past-30-day vaping days (vs menthol/mint: b=4.4, 95% CI (1 to 7.7); vs fruit/sweet: b=3.6, 95% CI (0.8 to 6.4)) and more episodes per vaping day versus fruit/sweet users (b=2.4, 95% CI (0.5 to 4.3)). Ice-flavour users were less likely than menthol/mint users to use JUUL/cartridge-based rechargeable (OR=0.1, 95% CI (0.03 to 0.45)) and more likely than sweet/fruit users to use disposable non-cartridge (OR=3.9, 95% CI (2.1 to 7.4)) devices than refillable/rechargeable tank/pen or other devices. Ice users had greater odds of past 30-day combustible tobacco use versus menthol/mint users (OR=2.7, 95% CI (1.3 to 5.7)) and vaping dependence symptoms than versus sweet/fruit users (OR=2.6, 95% CI (1.5 to 4.4)).ConclusionYoung adult use of ice flavoured e-cigarettes may be common and positively associated with combustible tobacco use, nicotine vaping frequency and dependence and use of disposable e-cigarette devices. Further study of the prevalence, determinants and health effects of ice flavoured e-cigarette use is warranted.

Project description:IntroductionE-cigarette advertising may benefit young adult cigarette smokers in transitioning to using e-cigarettes. We assessed whether e-cigarette advertising exposure was associated with subsequent e-cigarette use among young adult cigarette smokers.Aims and methodsData were from Waves 4 (2016-2018) and 5 (2018-2019) of the nationally representative Population Assessment of Tobacco and Health (PATH) study adult survey. Respondents were young adult established cigarette smokers at Wave 4 (18-34 years; n = 3391) and a subsample of those who tried to quit smoking cigarettes completely in the past year at Wave 5 (n = 1235). Multivariable logistic regressions were used to examine the associations between e-cigarette advertising exposure (by channel of exposure) and subsequent past-year e-cigarette use in general and e-cigarette use to quit smoking cigarettes, controlling for covariates.ResultsAt Wave 5, 43.4% of smokers reported past-year use of e-cigarettes; and 14.8% of smokers who tried to completely quit smoking reported past-year use of e-cigarettes to quit. E-cigarette advertising exposure was associated with subsequent past-year e-cigarette use (adjusted odds ratio [AOR] = 1.53, p < .0001, 95% confidence interval [CI] = 1.27, 1.86) and past-year use to quit smoking cigarettes (AOR = 1.65, p < .01, 95% CI = 1.19, 2.29). Advertising exposure through brick-and-mortar stores or websites/social media was similarly associated with both e-cigarette use behaviors.DiscussionExposure to e-cigarette advertising among U.S. young adult established cigarette smokers may be associated with subsequent e-cigarette use and use to quit smoking. More research is needed to understand the features of e-cigarette advertising (eg, discounts, flavors, smoker-targeted claims) that may shape perception and behavior related to e-cigarette use among young adult smokers.ImplicationsLittle is known about the associations between e-cigarette advertising exposure and e-cigarette use among young adult cigarette smokers who may benefit from switching to e-cigarettes. This study found that e-cigarette advertising exposure was positively associated with (1) subsequent e-cigarette use among U.S. young adult established cigarette smokers and (2) subsequent e-cigarette use to quit smoking cigarettes among those who tried to completely quit in the past year. These observed associations were driven by smokers who did not currently use e-cigarettes at baseline. E-cigarette advertising exposure through brick-and-mortar stores or websites/social media was also positively associated with subsequent e-cigarette use behaviors.

Project description:ImportanceDespite increasing use of cigarettes and electronic cigarettes (e-cigarettes) and related health effects among youth, few studies have reported their effects on eyes.ObjectiveTo examine the frequency and severity of ocular symptoms (ocular discomfort, pain, burning, itching, redness, dryness, glare, blurriness, strain, and headaches) in young e-cigarette and cigarette users.Design, setting, and participantsIn an observational cross-sectional study, a survey conducted in May 6 to 14, 2020, asked participants about use (ever, past 30 days, and past 7 days) of e-cigarettes and cigarettes. The participants included US individuals aged 13 to 24 years.Main outcomes and measuresAssociations between vision-related outcomes (general vision, severity/frequency of ocular symptoms) and tobacco use were analyzed using weighted multivariable logistic regressions, adjusting for sociodemographic factors, contact lens use, and other combustible use.ResultsThere were 2168 never users, 2183 ever users, 1092 past 30-day users, and 919 past 7-day users of e-cigarettes; 55.9% of e-cigarette ever users also used cigarettes (dual users). Of the 4351 respondents, 63.8% identified as female, and mean (SD) age was 19.1 (2.9) years. Between 1.1% and 3.9% of ever dual users reported severe to very severe ocular symptoms; between 0.9% and 4.3% reported daily symptoms, which was higher than the proportion of symptoms in e-cigarette- or cigarette-only users. Past 7-day dual users had more severe itching (adjusted odds ratio [AOR], 2.37; 95% CI, 1.36-4.13; P = .002), redness (AOR, 2.58; 95% CI, 1.50-4.46; P = .001), dryness (AOR, 2.89; 95% CI, 1.64-5.08; P < .001), glare (AOR, 2.56; 95% CI, 1.50-4.35; P = .001), blurriness (AOR, 2.47; 95% CI, 1.36-4.50; P = .003), headaches (AOR, 2.31; 95% CI, 1.34-4.00; P = .003); and more frequent pain (AOR, 3.45; 95% CI, 2.09-5.68; P < .001), burning (AOR, 3.08; 95% CI, 1.86-5.09; P < .001), and redness (AOR, 2.72; 95% CI, 1.69-4.36; P < .001) than all other participants. Past 30-day dual users had more severe dryness (AOR, 2.65; 95% CI, 1.61-4.36; P < .001) and more frequent pain (AOR, 3.33; 95% CI, 2.12-5.21; P < .001) than all other participants. Ever dual users experienced more severe dryness (AOR, 1.60; 95% CI, 1.05-2.43; P = .03) and blurriness (AOR, 1.79; 95% CI, 1.21-2.64; P = .003) and more frequent pain (AOR, 1.69; 95% CI, 1.13-2.53; P = .01) and blurriness (AOR, 1.63; 95% CI, 1.13-2.36; P = .009) than never users.Conclusions and relevanceIn this cross-sectional US study, adolescents and young adult users of both e-cigarettes and cigarettes had a higher likelihood of experiencing severe and frequent ocular symptoms, with past 7-day users reporting more symptoms than past 30-day users or ever users. These findings provide additional reasons for users of e-cigarettes and cigarettes to reduce their tobacco use to possibly prevent or minimize ocular symptoms.
