A longitudinal study of the association between e-cigarette use contexts and alcohol use problems among college students

Objective: Previous studies had explored the associations between e-cigarette use and alcohol use problems, yet they did not fully consider e-cigarette use contexts. This longitudinal study conducted a prospective examination of e-cigarette use contexts and alcohol use problems among college students. Participants: College e-cigarette users at three public universities from Fall 2019 to Fall 2020 were included (N = 377). Methods: A linear mixed model with a random intercept and random slope was employed to examine the longitudinal associations. Results: Higher frequencies of e-cigarette use (β = 0.38, p < 0.001), being hooked on e-cigarettes (β = 0.96, p < 0.01), using e-cigarettes for socializing purposes (β = 0.58, p < 0.05), and more occasions of co-using e-cigarettes with alcohol (β = 0.05, p < 0.001) were linked to more alcohol use problems. Conclusions: Intervention efforts should incorporate comprehensive screening that includes both e-cigarette and alcohol use, enhance awareness of peer influence, and provide at-risk populations with education regarding the potential synergistic effects of e-cigarette and alcohol co-use.

Exposure to e-cigarette and heated tobacco product advertisements via digital, traditional media, and points-of-sale: An examination of associations with use intentions and perceived risk among adults in Armenia and Georgia.

E-cigarette and heated tobacco product (HTP) marketing often leverages digital media and points-of-sale (POS) and advertises risk reduction, including in Armenia and Georgia where male cigarette use rates are high. Using 2022 survey data from Armenian and Georgian adults (n=1468, mean age=42.92 years, 51.4% female; and past-month use of e-cigarettes 3.2%, HTPs 2.7%, and cigarettes 31.6%), multivariable linear regression examined 4 outcomes - e-cigarette and HTP use intentions and perceived risk (1=not at all, to 7=extremely) - in relation to past-month e-cigarette or HTP advertisement exposure via digital media, traditional media, and POS, controlling for covariates (country, age, gender, education level, relationship status, children, past-month cigarette and e-cigarette/HTP use). E-cigarette and HTP use intentions were low (mean score=1.47, SD=1.39 each), while perceived risk was high (mean score=5.83, SD=1.6, and mean score=5.87, SD=1.56, respectively). Past-month exposure to e-cigarette and HTP advertisements, respectively, were 12.9% and 11.2% via digital media, 6.1% and 4.8% traditional media, and 22.5% and 21.1% POS. For e-cigarettes, ad exposure via digital media was associated with greater use intentions (β=0.24; 95% CI: 0.03-0.44), ad exposure via traditional media (β= -0.32; 95% CI: -0.55 - -0.09) and POS (β= -0.30; 95% CI: -0.60 - -0.004) was associated with lower risk perceptions. For HTPs, ad exposure via digital media (β=0.35; 95% CI: 0.14-0.56) and POS (β=0.21; 95% CI: 0.04-3.63) was associated with greater use intentions, and ad exposure at POS was associated with lower risk perceptions (β= -0.23; 95% CI: -0.42 - -0.03). Tobacco control efforts should monitor and regulate e-cigarette and HTP marketing, particularly via digital media which may effectively promote use, and via POS which may target and influence risk perceptions.

Cost Comparison and Spending on Tobacco Products: Evidence from A Nationally Representative Sample of Adult E-Cigarette Users.

Over 20 states and local jurisdictions in the U.S. have imposed e-cigarette taxes. It is important to evaluate how adult vapers, including those who also smoke respond to e-cigarette taxation. The purpose of this study is to examine factors associated with adult vapers' cost comparison between e-cigarettes and cigarettes (i.e., which one is perceived to be more expensive) and expenditures (i.e., dollars spent) on these two products. We recruited a nationally representative sample of 801 adult e-cigarette users in the U.S., who participated in an online survey in April-May 2023. Nested-ordered logit and ordinary least squares regressions were used in analysis. On average, adult vapers spent $82.22 per month on e-cigarettes, and dual users spent $118.77 per month on cigarettes. More frequent e-cigarette use, lower state-level e-cigarette taxes, age and exclusive use of rechargeable tank systems with e-liquids were associated with considering e-cigarettes as less expensive than cigarettes. Exclusive use of tank systems was associated with lower e-cigarette spending. Adults who used e-cigarettes more frequently preferred to report weekly (versus monthly) spending on e-cigarettes; among dual users, everyday smokers were more likely to think of weekly (versus monthly) spending on cigarettes compared to someday smokers. Among US adult vapers, tobacco use frequency and e-cigarette device type are closely related to cost measures; e-cigarette taxes are associated with cost comparison between e-cigarettes and cigarettes, suggesting potential financial disincentive for vaping. Policymaker may consider imposing differential taxes by e-cigarette product types due to their different costs to consumers. This study provides supportive evidence that e-cigarette taxes may impact how vapers compare the costs of e-cigarettes relative to cigarettes. Given different expenditures and cost comparisons by e-cigarette device types, tax and policy design may need to take into consideration of e-cigarette device types. We also found that indoor tobacco use restrictions in shared housing may reduce vaping, and future research is needed. The associations between socio-demographics and cost comparison and expenditures reflect known patterns in price responsiveness and vaping prevalence. Cost comparison and expenditures are related measures, which may further reflect product affordability.

Use of E-Cigarette, Traditional Cigarettes, and C-Reactive Protein: The Cross Cohort Collaboration

This cross-sectional study included 18,797 participants from six longitudinal cohorts (CARDIA, FHS Gen III, HCHS/SOL, MESA, MiHeart, and REGARDS). 5,806 of them were with high-sensitivity C-reactive protein (hs-CRP) measurements. We found that among exclusive electronic cigarette (EC) use was associated with significantly lower high-sensitivity C-reactive protein (hs-CRP) levels compared to exclusive combustible cigarette use, suggesting a potentially lower inflammatory burden. hs-CRP levels in dual users and former smokers currently using EC were comparable to those observed in exclusive cigarette smokers. In contrast, individuals who exclusively used ECs showed no significant difference in hs-CRP levels compared to never smokers. These findings have important implications for tobacco regulation, public health, and clinical practice, highlighting the need for continued monitoring of EC-related health impacts.

The prevalence of adolescent problem gambling: examining sociodemographic risk factors in New Mexico

ABSTRACT Problem gambling in adolescence can lead to significant negative consequences, yet few studies have examined the prevalence and risk factors among diverse youth populations. This study investigated gambling and related non-gambling activities and sociodemographic correlates of problem gambling in 2,533 high-school students in New Mexico aged 12–18 years (mean age 15.6), with an approximately equal gender distribution (49.3% male, 49.3% female, 1.4% unspecified). Overall, 3% screened positive for problem gambling, with higher rates among males (3.9%) than females (2.1%), Native American (4.5%), and Hispanic (3.3%) versus white (1.5%) students. In-person activities were more common than online activities for both gambling and non-gambling activities. Substance use behaviors, including binge drinking, e-cigarette, marijuana, and prescription painkiller use, were more prevalent among people with gambling problems. Controlling for demographics, the interaction between Hispanic ethnicity and past 30-day binge drinking was positively associated with problem gambling. A risk score combining substance use and housing instability also positively predicted problem gambling. These findings demonstrate sociodemographic and substance use risk factors for problem gambling among New Mexico adolescents. The study highlights the importance of considering diverse ethnic backgrounds and co-occurring risk behaviors in developing targeted prevention and intervention strategies for adolescent problem gambling across various cultural contexts.

What Is the Role of Imagined Futures in the Development of E-Cigarette Use among Young People?

Public health ‘gateway’ narratives concerning young people’s e-cigarette use warn against a future generation beset by escalating addiction and a possible epidemic of tobacco- and vaping-related illnesses. We argue that such imaginaries of vaping futures are in fact based in smoking pasts, which, while likely not ‘real’ in the sense of predicting the development of youth vaping, have real consequences through influencing the conditions of young people’s e-cigarette use. Drawing on a study of 14–18-year-old vapers, we consider how the future imaginaries of gateway thinking – characterised by escalating dependence – both oppose and intersect with a cultural stock of neo-liberal future imaginaries – marked by progressive independence and self-determination. We show how both sets of imaginaries are negotiated and entangled within the logics and practices of young vapers’ ‘futures-in-process’ to advance debates in the sociology of futures and offer a radical rethinking of substance use by youth.

Minority stress mediates associations of sexual minority state policies and tobacco use among US sexual minority young adults

IntroductionState policies surrounding sexual minority (SM) rights are associated with tobacco use among SM individuals. Research is scant regarding the role of distinct SM policy categories on SM young adults’ (SMYAs) tobacco use and mechanisms explaining these associations. MethodsWe analyzed 2023 survey data from 1100 SMYAs (ages 18–34; 14.2 % gender minority; 66.1 % bisexual+, 29.1 % monosexual; 53.2 % racial/ethnic minority) with representation across 45 US states and DC. Regression-based models examined: 1) direct associations of residing in states with negative and limited (vs. comprehensive) SM state policies with respect to 7 policy categories (relationship/parent recognition, nondiscrimination, religious exemptions, LGBTQ youth, healthcare, criminal justice, gender identity documents) with minority stress (mental health, internalized stigma, community connectedness); 2) direct associations of policy categories and minority stress with tobacco use (past-month cigarette, e-cigarette, any tobacco use, number of products used); and 3) indirect associations of policy categories with tobacco use through minority stress. ResultsRelative to residing in states with comprehensive policies, residing in states with limited relationship/parent recognition policies indirectly predicted higher odds of e-cigarette use through mental health; weaker nondiscrimination policies indirectly predicted using more tobacco products through internalized stigma; and negative healthcare policies indirectly predicted higher odds of cigarette and any tobacco use through community connectedness. ConclusionsThese novel findings regarding associations among distinct SM policy categories, minority stress mediators, and tobacco use outcomes warrant further examination to better understand these distinct mechanisms, ultimately to inform SM-related policy and advocacy efforts, as well as tobacco prevention and cessation efforts.

Desires and Needs for Quitting Both e-Cigarettes and Cigarettes Among Young Adults: Formative Qualitative Study Informing the Development of a Smartphone Intervention for Dual Tobacco Cessation.

Dual use of both e-cigarettes and cigarettes is popular among young adults and may lead to greater nicotine dependence and additive adverse health effects than single-product use. However, existing cessation programs target quitting either e-cigarettes or cigarettes, highlighting a need for interventions to help young adults quit both products (ie, dual tobacco cessation). This formative study is part of a larger project to develop a smartphone intervention for dual tobacco cessation among young adults. This study aimed to (1) explore desires for and experiences with quitting both e-cigarettes and cigarettes and (2) identify needs and preferences for dual tobacco cessation intervention programming. Semistructured interviews were conducted to elicit the need for and experience with dual tobacco cessation among 14 young adults (18-29 years old) recruited through Instagram (Meta) advertisements in 2023. We conducted a thematic analysis to identify common themes related to quitting experiences and cessation needs. Participants expressed a strong desire for dual tobacco cessation and had attempted to quit both tobacco products, mostly "cold turkey." The priority product for quitting first varied by the individual's perceived harm or level of consumption. Targets for dual tobacco cessation interventions included (1) highlighting the health effects of dual tobacco use compared with single product use, (2) providing cessation support to quit one prioritized product while cutting down the other product with the explicit goal to quit both, (3) emphasizing unique facilitators and barriers to quitting each product (eg, unpleasant smell of cigarettes facilitating smoking cessation and accessibility and flavors of e-cigarettes hindering vaping cessation), and (4) addressing co-use of tobacco with alcohol or cannabis. Participants wanted personalized interventions through smartphone apps that would tailor support to their tobacco use patterns and unique quitting goals and needs. They also suggested presenting intervention content in multimedia (eg, videos, graphic pictures, quizzes, and games) to increase engagement. This study provides important insights into young adults' experiences, needs, and preferences for dual tobacco product cessation. We highlight important targets for future smartphone apps to deliver personalized and tailored support to meet the heterogeneous needs and preferences of young people who want to quit using both e-cigarettes and cigarettes.

Social Media Exposure and Other Correlates of Increased e-Cigarette Use Among Adolescents During Remote Schooling: Cross-Sectional Study.

Little is known about the role of exposure to e-cigarette-related digital content, behavioral and mental health factors, and social environment on the change in adolescent e-cigarette use during COVID-19 shelter-in-place orders and remote schooling. The aim of the study was to examine changes in adolescent e-cigarette use during shelter-in-place and remote schooling in association with exposure to e-cigarette-related digital content and other correlates: stronger e-cigarette dependence, feeling lonely, inability to socialize, e-cigarette use to cope with shelter-in-place, and the number of family members aware of participants' e-cigarette use. A cross-sectional survey conducted between August 2020 and March 2021 included 85 California adolescents (mean age 16.7, SD 1.2 years; 39/85, 46% identified as female and 37/85, 44% as Hispanic) who reported e-cigarette use in the past 30 days. Multivariable penalized logistic regressions determined associations adjusted for age, race and ethnicity, and mother's education. The outcome of increased e-cigarette use was defined as more frequent use of e-cigarettes of the same or stronger nicotine or tetrahydrocannabinol concentration. Almost all respondents (83/85, 98%) reported using social media more since shelter-in-place, and 74% (63/85) reported seeing e-cigarette digital content. More than half (46/85, 54%) reported increased e-cigarette use during shelter-in-place. Most individuals who increased use were exposed to e-cigarette digital content (38/46, 83%) compared to those who did not increase e-cigarette use (25/39, 64%), but the association was nonsignificant after adjusting for demographics (adjusted odds ratio [AOR] 2.34, 95% CI 0.71-8.46). Respondents who felt lonely (AOR 3.33, 95% CI 1.27-9.42), used e-cigarettes to cope with shelter-in-place (AOR 4.06, 95% CI 1.39-13.41), or had ≥2 family members aware of participants' e-cigarette use (AOR 6.42, 95% CI 1.29-39.49) were more likely to report increased e-cigarette use. Almost all participants reported using social media more during shelter-in-place, with many respondents reporting increased e-cigarette use, and significant associations with loneliness and use to cope with shelter-in-place. Future interventions should consider leveraging digital platforms for e-cigarette use prevention and cessation and address the mental health consequences of the COVID-19 pandemic.

Prognosis after switching to electronic cigarettes following percutaneous coronary intervention: a Korean nationwide study.

Despite the increasing popularity of electronic cigarettes (E-cigarettes), the prognostic impact of switching to E-cigarettes in smokers with coronary artery disease who have undergone percutaneous coronary intervention (PCI) remains unclear. Using a nationwide cohort from the Korean National Health Insurance database, 17 973 adults (≥20 years) identified as smokers (based on a health screening examination within 3 years before PCI) who underwent health screening within 3 years after PCI were enrolled to determine changes in smoking habits. Patients were classified as continued combustible cigarette users, successful quitters, or switchers to E-cigarettes. The group switching to E-cigarettes was further divided into dual users (using both combustible and E-cigarettes) and those exclusively using E-cigarettes. Primary outcomes included major adverse cardiac events (MACEs), a composite of all-cause death, spontaneous myocardial infarction, and repeat revascularization. Among the total population, 8951 patients (49.8%) continued using combustible cigarettes, 1694 (9.4%) were switched to E-cigarettes, and 7328 (40.7%) successfully quit smoking after PCI. During a median follow-up of 2.4 years, the cumulative incidence of MACE was lower among E-cigarette switchers (10%) or quitters (13.4%) than among continued combustible cigarette users (17%). When continued combustible cigarette users were used as the reference, the multivariable-adjusted hazard ratios with 95% confidence intervals for MACE were 0.82 (0.69-0.98) for switchers to E-cigarettes and 0.87 (0.79-0.96) for successful quitters. Compared with dual users, entirely switching to E-cigarettes was associated with a significantly lower MACE risk (hazard ratio 0.71; 95% confidence interval 0.51-0.99). Among smokers who underwent PCI for coronary artery disease, switching to E-cigarette use (particularly complete transition) or quitting smoking was associated with reduced MACE risk than with continued combustible cigarette use.

Correlation Between Diverse Smoking Habits and the Risk of Developing Type 2 Diabetes: A Comparative Analysis.

Diabetes mellitus (DM) is a prevalent metabolic illness that arises as a result of a complex interplay between genetic predisposition, environmental influences, and lifestyle choices. The precise mechanisms elucidating the association between smoking and the onset of DMremain incompletely understood, despite the proposal of several ideas. The objective of this study ‎was to conduct a comparative analysis of blood glucose levels, hemoglobin A1c (HbA1c) levels, insulin hormone levels, and homeostasis model assessment of insulin resistance (HOMA-IR) ‎levels in diabetic patients who smoked and those who did not. The study included a total of 320 volunteers divided into four groups, with each group consisting of 80 volunteers. The first group served as the control group and consisted of ‎healthy individuals. The remaining three groups consisted of type 2 diabetes mellitus (T2DM) patients, categorized based on their smoking habits. The second ‎group comprised T2DM patients who did not smoke, the third group consisted of T2‎DM patients who smoked cigarettes, and the fourth group included T2DM patients ‎who smoked e-cigarettes.‎At recruitment, data on age, fat %, waist circumference (cm), and body mass index (kg/m2) was collected. Biochemical markers measured were fasting blood glucose (FBG), HbA1c, insulin, and HOMA-IR‎ levels. The findings demonstrated a statistically significant increase (P<0.001) in the levels of each parameter, particularly among patients with T2DM who engaged in e-cigarette smoking, compared to the control group.‎ It was found that engaging in dual smoking, which involves the use of both traditional cigarettes and e-cigarettes, was associated with a higher likelihood of elevated HbA1c levels and other negative health effects. When it comes to the management of diabetic patients, abstaining from smoking and participating in smoking cessation programs, for patients who smoke, should be the essential approaches. It was found that dual smokingled to a higher likelihood of elevated HbA1c levels and this association was most pronounced among male individuals, those who were physically inactive, and thoseclassified as obese. Further studies should be conducted on the detrimental health consequences associated with e-cigarettes, with a particular focus on enhancing the awareness of healthcare professionals and their patients of the potential risks. This is particularly significant due to the prevailing perceptionthat e-cigarettes are inherently "safe".

The Intersection of Sexual Orientation, Substance Use, and Mental Health: Findings from Hints 5.

The data for this study were obtained from the Health Information National Trends Survey (HINTS 5, Cycle 4). Sample participants included 3583 adults (93.87% heterosexuals). We used multinomial regression to measure the relative risk ratios (RRRs) of being a former and current user versus never a user of tobacco and e-cigarettes and binomial regression to measure the odds ratios of depression between the LGBTQ and heterosexuals. Current smoking prevalence is higher among LGBTQ participants (17.3%) compared to heterosexuals (11.0%). The disparity is even greater for e-cigarette use, with 7.3% of LGBTQ participants being current users versus 2.8% of heterosexuals and 24.5% of LGBTQ participants being former users compared to 9.3% of heterosexuals. Compared to heterosexuals, the relative risk ratio of being a current tobacco user among the LGBTQ participants was about 1.75 times higher [RRR = 1.75, 95%CI = 1.16, 2.64], and that of e-cigarette use was about 2.8 times higher [RRR = 2.81, 95%CI = 1.57, 5.05]. Among current e-cigarette users, heterosexual participants had 1.9 percentage points [risk difference = 1.94, 95%CI = 1.20, 3.13] higher probability of depression, whereas among the LGBTQ participants, the risk was about 3.7 times higher [OR = 3.67, 95%CI = 1.06, 12.74]. Our findings conclude that the LGBTQ are more likely to use tobacco and e-cigarettes compared to heterosexuals and that the risk of depression from e-cigarette smoking is more pronounced among the LGBTQ participants.

Conjunctival and Corneal Endothelium Profile in a Sample of Healthy Electronic Cigarette Smokers

Objective: Though e-cigarette is thought of as a healthy alternative way of smoking, the unknown nicotine concentration level and chemical compounds from the aerosol mist and flavourings are potentially harmful and may exert irritation or damage to the ocular surface. Thus, a cross-sectional study was conducted to identify the conjunctival and corneal endothelium profile among healthy e-cigarette smokers, and the relationship between smoking behaviour with the conjunctival and corneal endothelium profile. Material and Methods: Seventeen healthy e-cigarette smokers and 17 non-smokers were recruited for this study where their palpebral redness, bulbar redness, limbal redness, conjunctival roughness, central corneal thickness, endothelial cell density, and coefficient of variation of endothelium cell area were assessed using slit lamp biomicroscope and specular microscope. Results: There was a non-significant, higher mean rank observed in the total palpebral redness, total bulbar redness, total limbal redness, total conjunctival roughness, central corneal thickness, endothelial cell density, and coefficient of variation of the endothelium cell area in e-cigarette smokers compared to non-smokers (p-value&gt;0.05). Only smoking frequency and total palpebral redness showed a statistically significant, positive, and fair correlation (r=0.349, p-value=0.043), while no other smoking behaviour showed a significant correlation (p-value&lt;0.05). Conclusion: The use of e-cigarettes showed no significant impact on the conjunctival and corneal profile among the users, but further research with comprehensive evaluation is required in a larger sample size of more established e-cigarette smoking profiles.

E-cigarette retail outlets in Mexico: a country that bans the sale.

Restrictive e-cigarette policies have not allowed for the characterization of the sale of these tobacco products in the countries where they are implemented. This is because it is believed that there are no stores. However, the use of e-cigarettes persists in these countries. A content analysis of electronic cigarette points of sale through the internet in Mexico was conducted. Cross-sectional study. Structured searches were performed in the Google Maps search engine with the terms "electronic cigarette store" and "vape store" in combination with the name of each state of Mexico, in the period from October 2021 to February 2022. A total of 695 e-cigarette stores were located, of which 481 (69.2%) were physical stores, 207 hybrid stores (29.8%), 4 online stores (0.6%) and 3 (0.4%) vending machines. A total of 316 e-cigarette brands and 578 vape liquid brands were identified. The sales attraction strategy they used the most was free shipping of products (85.8%). Stores used WhatsApp (92.5%), Facebook (86.3%) and Instagram (74.4%) to promote their products. Only 35.1% of stores checked the age of their customers, of which, 95.9% asked if the customer was of legal age and 4.1% asked for the date of birth. In addition, 25.6% of the stores warned about nicotine addiction and 24.2% specifically about the ingredients of the liquids. E-cigarettes are widely available and marketed in a variety of retail outlets in Mexico. The high number of stores, brands of liquids, and e-cigarettes indicates non-compliance with existing regulations. E-cigarette consumption has increased globally, even in countries with restrictive regulations. However, there is limited data on the density and characteristics of vape stores in low- and middle-income countries with restrictive regulations. This study found no significant differences in e-cigarette sales between countries with permissive and restrictive regulations. Therefore, it is suggested that, in addition to establishing restrictive policies on the sale of e-cigarettes, their enforcement should also be monitored. Countries with restrictive measures should regulate Internet sales and promotion of e-cigarettes with greater emphasis.

Health Risks Associated with Adopting New-Generation Disposable Products Among Young Adults Who Use E-Cigarettes.

New-generation disposable e-cigarettes have become increasingly popular among young adults in the USA since the FDA's partial flavor ban. This study aims to examine longitudinal changes in health risks among young adults who adopted these novel products, as well as the health effects of device types beyond the effects of other important e-cigarette characteristics. This study recruited e-cigarette users via voluntary response sampling from three college campuses in the USA to respond to four-wave online surveys conducted in four consecutive semesters. Among the participants who adopted disposables during the study, their health risks (dependence symptoms, respiratory symptoms, combustible tobacco use) and e-cigarette consumption characteristics (use frequency, nicotine concentration and flavors) before and after the adoption were compared using paired-sample t- or McNemar's tests. Generalized linear mixed models with a random intercept were conducted on data from the entire sample to investigate the effects of device type (tank, cartridge/pod, disposable) on health risks, controlling for other e-cigarette consumption characteristics. The study sample of 650 e-cigarette users were, on average, 20 years old, with 49% being male, 70% being White, and 13% being Hispanic. Adopting disposables may increase secondary dependence motives (t = 2.42, p < 0.05) and the use of higher levels of nicotine concentration (t = 2.09, p < 0.05) and sweet flavors (x2 = 22.53, p < 0.05) but decrease the number of times of vaping per day (t = -2.18, p < 0.05) and the use of menthol flavors (x2 = 4.57, p < 0.05). Tank use is associated with a higher level of primary dependence motives (b = 0.1998, p < 0.05) and a greater odds of using combustible tobacco (b = 0.4772, p < 0.05). Although disposable use is not associated with the likelihood of using combustible tobacco, it is associated with higher levels of both primary (b = 0.2158, p < 0.05) and secondary (b = 0.2533, p < 0.05) dependence motives. It is not the device type, but rather the frequency of vaping, that affects respiratory symptoms (b = 0.0602, p < 0.05). The findings indicate that when young adults switch to disposables, their e-cigarette dependence and use of sweet-flavored e-liquids increase. Even after controlling for use frequency, nicotine concentration and flavors, using disposables is related to not only instrumental motives that are influenced by psychological and environmental contexts but also heavy, automatic use that can operate without environmental cues. Given the health risks associated with disposable e-cigarettes, more comprehensive tobacco product regulations that consider the impact of device types may be needed.
