Abstract
ABSTRACT Despite the decline in the prevalence of e-cigarette use among youth during the coronavirus disease 2019 pandemic, more than 2.5 million of US high and middle schoolers are still using e-cigarettes. Furthermore, those who use e-cigarettes are starting at a younger age and are using them more intensely, reflecting, at least in part, a high addiction liability of modern e-cigarettes. Beyond addiction, accumulating evidence suggests that, in the short-term, e-cigarettes are associated with cardiovascular and pulmonary effects, whereas the long-term effects of e-cigarette use are yet to be established. The aim of this review is to synthesize current knowledge on e-cigarette use among youth, including established and potential risks and efforts to date to curb youth exposure to e-cigarettes. In addition, we provide recommendations for health care providers, researchers, and other stakeholders to address this significant public health issue.

Informing the development of interventions for e-cigarette use and prevention of transition to cigarette smoking in young adults: A qualitative study. Prev Med Rep 2023; 35:102332. [PMID: 37519444 PMCID: PMC10382918 DOI: 10.1016/j.pmedr.2023.102332] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2023] [Revised: 07/13/2023] [Accepted: 07/17/2023] [Indexed: 08/01/2023] Open
Abstract
E-cigarette use in young individuals may increase risk for cigarette smoking initiation. Over half of young adults who use e-cigarettes voiced their desire to quit e-cigarettes. Mobile-based interventions may allow for an easy-to-use platform to engage young adults in cessation services and reduce risk for cigarette uptake. To inform development of such programs, this study sought to gather information about what young adults want to see included in e-cigarette cessation interventions that also target future smoking risk. Nine online focus groups (n = 33) were conducted in July and August 2022 with young adults who either (1) currently used e-cigarettes, (2) formerly used e-cigarettes, or (3) initiated nicotine use with e-cigarettes but subsequently smoked cigarettes (dual use). Two research team members independently coded the transcripts and identified themes. A third researcher independently reviewed the coding and thematic analysis. Participants believed that mobile-based interventions should include peer support, ways to track cessation progress, education about the harms of e-cigarettes, gamification, and incentivization. They also believed that to prevent future cigarette smoking, interventions need to include education about the harms of smoking, teach refusal skills for offers to smoke, and incorporate personal anecdotes from former smokers. To increase their readiness, motivation, and self-efficacy to quit, participants who continue to use e-cigarettes reported needing effective substitutions to replace e-cigarettes, barriers to hinder their access to e-cigarettes, and social support. Findings from this study may be useful to incorporate when developing interventions designed to reduce e-cigarette use and risk of progression to smoking for young adults.

Abstract
BACKGROUND Despite measures to reduce young people's access to electronic cigarettes (ECs), or "vapes", many countries have recorded rising youth vaping prevalence. We summarised studies documenting how underage youth in countries with minimum age sales restrictions (or where sales are banned) report accessing ECs, and outline research and policy implications. METHODS We undertook a focused literature search across multiple databases to identify relevant English-language studies reporting on primary research (quantitative and qualitative) and EC access sources among underage youth. RESULTS Social sourcing was the most prevalent EC access route, relative to commercial or other avenues; however, social sourcing dynamics (i.e., who is involved in supplying product and why) remain poorly understood, especially with regard to proxy purchasing. While less prevalent, in-person retail purchasing (mainly from vape shops) persists among this age group, and appears far more common than online purchasing. CONCLUSIONS Further research examining how social supply routes operate, including interaction and power dynamics, is crucial to reducing youth vaping. Given widespread access via schools and during social activities and events, exploring how supply routes operate and evolve in these settings should be prioritized. Inadequate compliance with existing sales regulations suggest greater national and local policy enforcement, including fines and licence confiscation for selling to minors, is required at the retailer level.

Abstract
INTRODUCTION Globally, the use of vapes, or e-cigarettes, is increasing. While vaping is less harmful than smoking and may help smokers to quit, there is also the possibility that vaping may lead to smoking. The current study aimed to determine the prevalence of vaping and smoking in Aotearoa New Zealand and explore longitudinal pathways between smoking status and vape use. METHOD Data related to smoking and vaping status was analysed from Times 10, 11 and 12 across 2018-2020 of the New Zealand Attitudes and Values study, a large, representative, multi-wave study of adults living in New Zealand. Weighted descriptive analyses were used to determine prevalence rates of vaping and smoking and a generalised linear modelling approach was used to examine the likelihood of changing to, or taking up, the other behaviour in the transition between time points. RESULTS Broadly, the prevalence of smoking was found to be decreasing over time while the prevalence of vaping was increasing. Despite these general trends, no differences were observed in the likelihood of transitioning from smoking to vaping or from vaping to smoking, indicating that either pathway was equally as likely. DISCUSSION AND CONCLUSIONS The current findings demonstrate that vaping appeared to be just as likely to have a gateway effect to smoking as it was to have a cessation effect. This highlights the need for greater consideration regarding vaping-related policies and restrictions.

Abstract
Background The rapid increase in electronic nicotine product (ENP) use among young people has been a global public health challenge, given the potential harm of ENPs and nicotine dependence. Many countries have recently introduced legislations to regulate ENPs, but the impacts of these policies are poorly understood. This systematic review aims to critically synthesise empirical studies on the effects of global regulations regarding ENPs on the prevalence of use, health outcomes and their determinants, using the 4A marketing mix framework (acceptability, affordability, accessibility and awareness). Methods Following the PRISMA guideline, we searched PubMed, Embase, Scopus, Web of Science, Academic Search Complete, Business Source Complete, and APA PsycINFO databases from inception until June 14, 2022 and performed citation searches on the included studies. Reviewed literature was restricted to peer-reviewed, English-language articles. We included all pre-post and quasi-experimental studies that evaluated the impacts of e-cigarette policies on the prevalence of ENP use and other health outcomes. A modified Joanna Briggs Institute (JBI) Critical Appraisal checklist for quasi-experimental studies was used for quality assessment. Due to heterogeneity of the included studies, we conducted a narrative synthesis of evidence. Results Of 3991 unduplicated records screened, 48 (1.2%) met the inclusion criteria, most were from high-income countries in North America and Europe and 26 studies measured self-reported ENPs use. Flavour restrictions significantly decreased youth ENP use and taxation reduced adult use; mixed results were found for the impacts of age restrictions. Indoor vaping restrictions and the European Tobacco Products Directive (TPD) did not seem to reduce ENP use based on existing studies. Changes in determinants such as sales and perceptions corroborated our conclusions. Few studies assessed the impacts of other regulations such as advertising restrictions and retail licensing requirements. Conclusions Flavour restrictions and taxes have the strongest evidence to support effective control of ENPs, while others need powerful enforcement and meaningful penalties to ensure their effectiveness. Future research should focus on under-examined policies and differential impacts across sociodemographic characteristics and countries. Registration PROSPERO CRD42022337361.

Abstract
Background To support tobacco control efforts, this study sought to characterize longitudinal transitions in use of electronic nicotine delivery systems (ENDS) and cigarettes. Methods Participants were nationally representative samples of 53,729 US adults from Waves 3-5 (2015-2019) of the Population Assessment of Tobacco and Health Study. We examined behavioral transitions (initiation, relapse, progression, and cessation) in ENDS and cigarette use across waves. Weighted generalized estimating equation models adjusted for sociodemographic variables. Findings Of never ENDS users at baseline, an estimated 1.7% reported initiating ENDS use by follow-up. Of former ENDS users, an estimated 12.1% relapsed into ENDS use. Of periodic ENDS users at baseline, 13% progressed to established ENDS use. Of baseline current ENDS users, 46.3% discontinued ENDS use. The corresponding transitions for cigarette smoking were 1.6% (initiation), 4.8% (relapse), 21.1% (progression), and 14% (discontinuation). Adults aged 18-24 (vs. older age), Hispanics (vs. non-Hispanic white), and past 12-month cannabis users were more likely to initiate ENDS or cigarettes (all p < 0.05). Having any internalizing mental health symptoms increased the odds of ENDS initiation, while externalizing symptoms increased the odds of cigarette initiation. Those who perceived nicotine as very harmful (vs. none/low harm) were more likely to discontinue ENDS. Current cigarette users (vs. non-users) at baseline were more likely to initiate, relapse, or discontinue ENDS (all p < 0.05) and vice versa. Interpretation We observed high changeability in ENDS and cigarette use among US adults over time. In absolute terms, ENDS use grew, while smoking fell. Tobacco control programs should focus on priority populations, including young adults and people with internalizing and externalizing mental health symptoms.

Responses to potential nicotine vaping product flavor restrictions among regular vapers using non-tobacco flavors: Findings from the 2020 ITC Smoking and Vaping Survey in Canada, England and the United States. Addict Behav 2022; 125:107152. [PMID: 34695685 PMCID: PMC9094050 DOI: 10.1016/j.addbeh.2021.107152] [Citation(s) in RCA: 4] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/07/2021] [Revised: 09/03/2021] [Accepted: 10/11/2021] [Indexed: 01/07/2023]
Abstract
INTRODUCTION Some jurisdictions have implemented nicotine vaping product (NVP) flavor restrictions because of concerns about rising adolescent use. However, little is known how these restrictions may impact adult vapers. This study describes the level of support and predictive behavioral responses to a hypothetical NVP ban on non-tobacco flavors among regular adult vapers who only use flavors that would be banned. METHODS Data came from 851 regular vapers (all current or ex-smokers) participating in the 2020 ITC Four Country Smoking and Vaping Survey in Canada, England, and the United States (US). A random sample of respondents in each country received and completed the questions about flavor bans: (1) do you support or oppose a ban on all non-tobacco flavors; and (2) what would you do if all flavors were banned, with the exception of tobacco in the US, and tobacco and menthol in Canada and England. Those who used tobacco-flavored or unflavored NVPs were excluded from all analyses, and additionally, vapers of menthol flavor in Canada and England were excluded from Aim 2. RESULTS Overall, 53.6% of vapers were strongly opposed to flavor bans, 28.2% were opposed, 9.3% were in support, 3.6% were in strong support, and 5.2% did not know. Predicted behavioral responses were: 28.8% would continue vaping an available flavor, 28.3% would find a way to get their banned flavor(s), 17.1% would stop vaping and smoke instead, 12.9% said that they would stop vaping and not smoke, and 12.9% do not know what they would do. Responses to a potential flavor ban largely varied by smoking and vaping status, and by the level of support of a flavor restriction policy. CONCLUSIONS At this time, it is not clear what net population-level consequences would occur if non-tobacco flavored NVPs were prohibited. While a majority of vapers in this study opposed this policy, and many vapers would not be willing to switch to available flavors, there was considerable variability in predicted behavioral responses.
