Abstract
BACKGROUND The tobacco industry has a history of using language to downplay the harms associated with cigarettes and mislead consumers and policymakers. Emerging evidence suggests similar tactics are being used in the context of e-cigarettes; however, exploration of the impact of product name on attitudes towards e-cigarettes and susceptibility to use is lacking. This experimental study explored whether attitudes towards e-cigarettes and susceptibility to use are influenced by the names used by the industry to describe and market these products. METHOD An accredited web panel provider recruited a sample of 383 Australians aged 12-29 years who had never smoked to participate in an online survey that featured an embedded experiment. Participants were randomly allocated to one of three conditions, each of which used a different name to describe e-cigarettes (condition 1: 'e-cigarettes', condition 2: 'vapes'; condition 3: either 'IGETS', 'Puff Bars', 'HQD Cuvies' or 'Gunnpods'). The survey assessed respondents' overall opinion of the product described; attitudes towards the product; liking of the product; and curiosity, willingness and intentions to use the product. RESULTS Those in the 'brand name' condition scored higher than those in the 'e-cigarettes' condition on all dependent variables. Those in the 'vapes' condition scored higher than those in the 'e-cigarettes' condition on product attitude. CONCLUSION Findings indicate that the use of brand names and terms such as 'vapes' instead of 'e-cigarettes' results in more favourable attitudes towards e-cigarettes and susceptibility to use among young Australians. Results highlight the problematic influence of promotional language use favoured by industry.

Tobacco industry strategies to influence the regulation of new and emerging tobacco and nicotine products in Latin America and the Caribbean. Rev Panam Salud Publica 2024; 48:e43. [PMID: 38859810 PMCID: PMC11164239 DOI: 10.26633/rpsp.2024.43] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/22/2023] [Accepted: 01/02/2024] [Indexed: 06/12/2024] Open
Abstract
Objective To document tobacco industry strategies to influence regulation of new and emerging tobacco and nicotine products (NETNPs) in Latin America and the Caribbean. Methods We analyzed industry websites, advocacy reports, news media and government documents related to NETNPs, focusing on electronic cigarettes and heated tobacco products. We also conducted a survey of leading health advocates. We applied the policy dystopia model to analyze industry action and argument-based strategies on NETNP regulations. Results Industry actors engaged in four instrumental strategies to influence NETNP regulation - coalition management, information management, direct involvement in and access to the policy process, and litigation. Their actions included: lobbying key policy-makers, academics and vaping associations; providing grants to media groups to disseminate favorable NETNP information; participating in public consultations; presenting at public hearings; inserting industry-inspired language into draft NETNP legislation; and filing lawsuits to challenge NETNP bans. The industry disseminated its so-called harm reduction argument through large/influential countries (e.g., Argentina, Brazil, and Mexico). Industry discursive strategies claimed NETNPs were less harmful, provided safer alternatives, and should be regulated as so-called harm reduction products or have fewer restrictions on their sale and use than those currently in place. Conclusion Our analysis provides a better understanding of industry strategies to undermine tobacco and nicotine control. To help counter industry efforts, health advocates should proactively strengthen government capacities and alert policy-makers to industry attempts to create new regulatory categories (so-called reduced-risk products), provide misleading information of government authorizations of NETNPs, and co-opt so-called harm-reduction messages that serve the industry's agenda.

Abstract
Electronic nicotine delivery systems (ENDS) - which include electronic cigarettes or e-cigarettes, or simply e-cigs, and marijuana vaping have become increasingly popular. ENDS devices have been established as one of the tobacco quit methods and promoted to be safer compared to traditional tobacco cigarettes. Emerging evidence demonstrates that e-cigarette and marijuana vape use can be harmful, with potential associations with cancer. Herein, we summarize the level of evidence to date for altered immune response, with a focus on cancer risks in the offspring after maternal use of, or aerosol exposures from, ENDS or marijuana vape during pregnancy. From 27 published articles retrieved from PubMed, we sought to find out identified carcinogens in ENDS aerosols and marijuana vapor, which cross the placental barrier and can increase cancer risk in the offspring. Carcinogens in vaping aerosols include aldehydes, metals, tobacco-specific nitrosamines, tobacco alkaloids, polycyclic aromatic hydrocarbons, and volatile organic compounds. Additionally, there was only one passive vaping exposure case study on a human fetus, which noted that glycerol, aluminum, chromium, nickel, copper, zinc, selenium, and lead crossed from the mother to the offspring's cord blood. The carcinogens (metals) in that study were at lower concentrations compared to the mother's biological matrices. Lastly, we observed that in utero exposures to ENDS-associated chemicals can occur in vital organs such as the lungs, kidneys, brain, bladder, and heart. Any resulting DNA damage increases the risk of tumorigenesis. Future epidemiological studies are needed to examine the effects of passive aerosol exposures from existing and emerging electronic nicotine and marijuana products on developing offspring to cancer.

Abstract
INTRODUCTION Instagram is a popular social networking platform for sharing photos with a large proportion of youth and young adult users. We aim to identify key features in anti-vaping Instagram image posts associated with high social media user engagement by artificial intelligence. AIMS AND METHODS We collected 8972 anti-vaping Instagram image posts and hand-coded 2200 Instagram images to identify nine image features such as warning signs and person-shown vaping. We utilized a deep-learning model, the OpenAI: contrastive language-image pre-training with ViT-B/32 as the backbone and a 5-fold cross-validation model evaluation, to extract similar features from the Instagram image and further trained logistic regression models for multilabel classification. Latent Dirichlet Allocation model and Valence Aware Dictionary and sEntiment Reasoner were used to extract the topics and sentiment from the captions. Negative binomial regression models were applied to identify features associated with the likes and comments count of posts. RESULTS Several features identified in anti-vaping Instagram image posts were significantly associated with high social media user engagement (likes or comments), such as educational warnings and warning signs. Instagram posts with captions about health risks associated with vaping received significantly more likes or comments than those about help quitting smoking or vaping. Compared to the model based on 2200 hand-coded Instagram image posts, more significant features have been identified from 8972 AI-labeled Instagram image posts. CONCLUSION Features identified from anti-vaping Instagram image posts will provide a potentially effective way to communicate with the public about the health effects of e-cigarette use. IMPLICATIONS Considering the increasing popularity of social media and the current vaping epidemic, especially among youth and young adults, it becomes necessary to understand e-cigarette-related content on social media. Although pro-vaping messages dominate social media, anti-vaping messages are limited and often have low user engagement. Using advanced deep-learning and statistical models, we identified several features in anti-vaping Instagram image posts significantly associated with high user engagement. Our findings provide a potential approach to effectively communicate with the public about the health risks of vaping to protect public health.

Abstract
INTRODUCTION The surge in popularity of e-cigarettes and heated tobacco products (HTPs) in South Korea, driven by perceived health benefits and COVID-19-related concerns, has led to increased advertising claims about their safety despite ongoing debates about their health effects. This study explores the marketing strategies of online e-cigarette and HTP retailers in South Korea pre- and post-COVID-19, examining potential misleading claims and providing a foundation for future regulatory measures. METHODS We conducted a comprehensive study of eight major e-commerce platforms and three dominant search engines in South Korea to analyze the marketing and advertising strategies of e-cigarettes and heated tobacco products (HTPs) (n=774). Using specific keywords, promotional strategies were identified and categorized, after which statistical analysis was conducted to understand the frequency and proportion of these strategies, highlighting differences between HTP and e-cigarette sellers. RESULTS Our analysis reveals a significant rise in the number of online retailers selling e-cigarettes and HTPs following the COVID-19 pandemic, with the promotional strategies 'Stay home and vape' and 'Trendy' being the most prevalent. Trends also indicate a shift in promotional strategies over the years, with a marked increase in health reassurance themes and appeals to trendiness, particularly targeting female consumers, which were used significantly more at HTPs stores. CONCLUSIONS The study highlights the need for stricter regulation due to the potential health risks posed by the aggressive marketing strategies of e-cigarette and HTP online retailers in South Korea, amplified by the COVID-19 pandemic.

Abstract
INTRODUCTION Coupons are an effective, frequently used tobacco marketing strategy. This study examined prospective associations between cumulative exposure to e-cigarette coupons and changes in e-cigarette use among U.S. adults. METHODS Data were from a representative U.S. adult cohort (n=19,824) in the Population Assessment of Tobacco and Health Study (waves [W] 2, 3, 4, and 5), collected from October 2014 to November 2019. Analysis was conducted in 2022. Four logistic regression models examined associations of a number of waves for which participants received e-cigarette coupons during W2-W4 with changes in e-cigarette use: W2 never use to W5 current use (initiation); W2 current nondaily use to W5 daily use (progression); W2 current use to W5 former use (cessation), and W2 former use to W5 current use (return-to-use). RESULTS Overall, 66.1% of U.S. adults never used e-cigarettes, 10.6% currently used e-cigarettes, and 23.4% formerly used e-cigarettes at W2. The average number of waves for which participants received e-cigarette coupons during W2-W4 was 0.13: 0.10 among W2 individuals who never used e-cigarettes, 0.30 among individuals who currently used e-cigarettes on a nondaily basis, 0.50 among individuals who currently used e-cigarettes, and 0.17 among individuals who formerly used e-cigarettes. Receiving coupons at increased waves was associated with (1) greater odds of initiation (AOR=1.58, 95% CI=1.26-1.97); (2) lower odds of cessation (AOR=0.78, 95% CI=0.67-0.91); and (3) increased odds of return-to-use (AOR=1.39, 95% CI=1.14-1.69). Findings did not differ by W2 cigarette smoking status. CONCLUSIONS E-cigarette coupons may encourage and sustain e-cigarette use. Policies restricting e-cigarette coupons may curb e-cigarette use.

Abstract
BACKGROUND The rising prevalence of electronic cigarette (E-cigarette) use among adolescents is a major public health concern. This study investigates the prevalence of E-cigarette use among male adolescents in Al-Ahsa, Saudi Arabia, and explores associated factors. METHODOLOGY A cross-sectional study was conducted from December 2022 to April 2023, involving 476 male students aged 12 to 19. Data were collected through structured questionnaires, covering sociodemographic information, E-cigarette usage patterns, reasons for use, sources of acquisition, awareness of nicotine content, and perceptions of harm. Statistical analysis was performed using SPSS 25 (IBM Corp., Armonk, NY), with significance set at p < 0.05. RESULTS The study revealed a prevalence of 17.4% E-cigarette use among participants, with 12.6% using E-cigarettes exclusively and 4.8% concurrently with traditional tobacco cigarettes. Key findings included initiation as early as age eight, sustained and frequent use, and motivations including peer influence (61.4%), curiosity (31.3%), and flavored options (26.5%). Online platforms (34.9%) and shopping malls (28.9%) were the primary sources of E-cigarette acquisition. Most participants were aware of the nicotine content (84.3%) and believed E-cigarettes were harmful (86.7%). Importantly, 69.9% expressed intentions to quit, with 44.6% planning to do so within 30 days. Significant associations were found between E-cigarette use, education level, and having friends who smoke. CONCLUSION This study highlights the prevalence of E-cigarette use among male adolescents in Al-Ahsa, Saudi Arabia, and identifies peer influence, curiosity, and appealing flavors as driving factors. Targeted prevention and intervention programs, along with regulatory efforts to restrict access, are urgently needed to address this growing public health issue. Increasing awareness of E-cigarette risks and providing cessation support are vital steps towards mitigating E-cigarette use among Saudi male adolescents.

Abstract
Background Health warning labels (HWLs) are evidence-based tobacco control strategies; however, their application to e-cigarettes and related impacts (e.g. on perceived risk), including across countries with different regulations, are understudied. Design and Methods Using 2021 survey data from 927 US and Israeli adults reporting past-month tobacco use, multivariate analyses examined: (1) sociodemographics in relation to self-reported impact of e-cigarette HWLs (i.e. more concerned about e-cigarette use, reassured, no effect) among those who noticed e-cigarette HWLs (multinomial regressions); and (2) HWL impacts in relation to use intentions and perceived addictiveness and harm (linear regressions). Results Among those who noticed HWLs (n = 835, 90.1%), 34.1% reported HWLs resulted in greater concern about e-cigarette use, 45.5% no effect, and 20.4% reassurance. Factors associated with greater concern (vs no effect) included e-cigarette non-use (vs use; aOR = 1.69, 95% CI:1.22, 2.38), US (vs Israel) resident (aOR = 1.65, 95% CI:1.16, 2.34), age 18-25 (vs 36-45; aOR = 1.72, 95% CI:1.11, 2.67), and more education (aOR = 1.85, 95% CI:1.30, 2.63). Factors associated with being reassured (vs no effect) included use of cigarettes (aOR = 1.71, 95% CI:1.06, 2.75), e-cigarettes (aOR = 2.64, 95% CI:1.77, 3.94), and other tobacco (aOR = 2.11, 95% CI:1.39, 3.21), and Israeli resident (aOR = 2.33, 95% CI:1.47, 3.70). Not noticing HWLs (vs no effect) correlated with lower intentions (β = -0.44, 95% CI:-0.87, -0.01), perceived addictiveness (β = -0.61, 95% CI:-1.05, -0.18), and harm (β = -0.56, 95% CI:-0.95, -0.18); reassurance correlated with greater use intentions (β = 0.48, 95% CI:0.12, 0.83); and greater concern was unassociated with use intentions or perceived risk. Conclusion Effects of differing e-cigarette HWLs in distinct subpopulations warrant research. Despite being noticed, they may have no effect or encourage e-cigarette use.

Abstract
Despite claims of safety or harm reduction for electronic cigarettes (E-cig) use (also known as vaping), emerging evidence indicates that E-cigs are not likely safe, or necessarily safer than traditional cigarettes, when considering the user's risk of developing vascular dysfunction/disease. E-cigs are different from regular cigarettes in that E-cig devices are highly customizable, and users can change the e-liquid composition (such as the base solution, flavors, and nicotine level). Since the effects of E-cigs on the microvascular responses in skeletal muscle are poorly understood, we used intravital microscopy with an acute (one-time 10 puff) exposure paradigm to evaluate the individual components of e-liquid on vascular tone and endothelial function in the arterioles of the gluteus maximus muscle of anesthetized C57Bl/6 mice. Consistent with the molecular responses seen with endothelial cells, we found that the peripheral vasoconstriction response was similar between mice exposed to E-cig aerosol or cigarette smoke (i.e., 3R4F reference cigarette); this response was not nicotine dependent, and endothelial cell-mediated vasodilation was not altered within this acute exposure paradigm. We also report that, regardless of the base solution component [i.e., vegetable glycerin (VG)-only or propylene glycol (PG)-only], the vasoconstriction responses were the same in mice with inhalation exposure to 3R4F cigarette smoke or E-cig aerosol. Key findings from this work reveal that some component other than nicotine, in inhaled smoke or aerosol, is responsible for triggering peripheral vasoconstriction in skeletal muscle, and that regardless of one's preference for an E-cig base solution composition (i.e., ratio of VG-to-PG), the acute physiological response to blood vessels appears to be the same. The data suggest that vaping is not likely to be 'safer' than smoking towards blood vessels and can be expected to produce and/or result in the same adverse vascular health outcomes associated with smoking cigarettes.
