There is limited understanding of what influences vaping cessation, especially as vaping regulations change, and different jurisdictions have different regulations. This study involves 281 ex-vapers (16–24 years) from Nova Scotia, Canada. A content analysis was used to understand and compare youth and young adults’ (YA) experiences of quitting vaping. Both helpful and unhelpful factors for quitting vaping were identified; each category had five themes and twenty-one sub-themes. Helpful factors were consistent across both age categories and included planned and unplanned vaping control interventions, health concerns, social support, evidence-based support, and unassisted quitting methods. Similarly, the five themes identified as unhelpful factors were consistent for both age groups: negative personal implications, negative social influences, planned and unplanned vaping control interventions, the side effects of previous use, and simultaneous and alternative substance use. Policies that limit access and raise awareness about lung health and well-being can help youth quit vaping. For YAs, increasing awareness about social support and health concerns is crucial. Raising e-cigarette costs and reducing vaping normalization supports quitting for YAs. Stress reduction and training to handle social pressure could aid youth, while YAs might benefit from treatment for other substance use to help with nicotine quitting. Full article

The prevalence of e-cigarette use (vaping) in young adults is concerning, particularly because the initiation of combustible tobacco use is higher in e-cigarette vapers. It is unclear why young, never-smoker vapers decide to start smoking cigarettes, but they may be influenced by perceptions of health risks and accessibility. We designed a social media questionnaire to assess factors driving the initiation of combustible tobacco use by e-cigarette vapers (multi-inhalant use) and switches between inhalant types. Respondents reported an earlier initiation of combustible tobacco versus vaping (18 vs. 19, respectively, p < 0.0001), greater ease of obtaining combustibles versus vaping products (p < 0.01), and pleasure of vaping being equivalent to that of smoking. The majority of subjects (57%) reported smoking first prior to adding vaping devices, 32% reported initiating both smoking and vaping within 12 months of one another, and 11% reported initiating vaping first. Among respondents (n = 864) who switched from vaping to smoking (n = 104), the primary reasons included 1. the perception that smoking was healthier (44%) and 2. greater accessibility of cigarettes (40%). For those who switched from smoking to vaping (n = 178), the predominant motivations included 1. having friends or family who vape (40%) and 2. the perception that vaping was healthier (36%). Among multi-inhalant users (n = 223), key factors driving this behavior included 1. increased enjoyment (47%) and 2. greater variety (42%). Our findings imply that there is no single, dominant reason driving the initiation of combustible use or switching from one inhalant to another. Further, tobacco users are receiving mixed messaging, leading many to believe that combustible tobacco is the healthier option. Public health interventions are needed to prevent the initiation of e-cigarette vaping by youth and to educate the public about the health effects of tobacco products. Full article

Background and Objectives: Pneumothorax is a medical condition characterized by the accumulation of air in the pleural cavity, leading to lung collapse. While cigarette smoking is a well-known risk factor, the role of electronic cigarettes is less understood. This systematic review aimed to evaluate the outcomes of vaping-associated pneumothorax, in addition to its clinical features and management strategies, by compiling published case reports and case series. Materials and Methods: The choice to use case reports and case series was due to the limited availability of other types of studies on this emerging condition, as vaping-associated pneumothorax is relatively rare and primarily reported in isolated cases. Following the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines, we conducted a systematic search of six databases for case reports and case series. Data extraction and quality assessment were performed independently by multiple reviewers. Results: Seven case reports and four case series with a total number of 16 patients were included. Most patients were young, underweight men who presented with chest pain and shortness of breath. Conventional cigarette and cannabis use were commonly reported alongside vaping. The main treatment was the insertion of a chest tube, with surgical interventions reserved for severe cases. Patients who were treated non-surgically exhibited a higher recurrence rate. Additionally, specific symptoms such as chest pain radiating to the ipsilateral shoulder were associated with a higher recurrence rate. Conclusions: Clinicians should be vigilant for pneumothorax in at-risk individuals, consider targeted screening for symptomatic vapers, and prioritize early surgical intervention in recurrent cases to reduce complications. Further research is needed to understand the pathophysiology of vaping-associated spontaneous pneumothorax and optimal management strategies. Full article

Environmental exposure to e-cigarettes is a significant yet often overlooked issue in the medical field. In this review, we examine various aspects of exposure mechanisms, including the risks of secondhand and thirdhand vaping. Our findings highlight numerous environmental concerns related to the fabrication, consumption, and waste management of e-cigarettes. Additionally, we address the pressing issue of plastic pollution linked to vaping products. We also explore methods to protect passive vapers and propose strategies aimed at mitigating the environmental impact of e-cigarettes as well as safeguarding innocent bystanders. Full article

Background: E-cigarettes, initially designed for nicotine consumption, are now increasingly being used to smoke cannabis, resulting in a growing trend known as “dual vaping”. This term describes individuals, referred to as “dual users”, who use e-cigarettes for both substances. This study aims to review and analyze existing research on dual vaping, with a focus on the associated health risks and behavioral patterns. Methods: A narrative review of the literature was conducted using PubMed. Studies focusing on individuals who use electronic cigarettes for vaping tobacco and cannabis, either chronically or episodically, were examined. Relevant articles were identified and thematically synthesized to provide a comprehensive overview of the topic. Results: Dual vaping was found to be prevalent among younger men, White and Hispanic populations, and individuals with higher economic status and educational level. The use of one substance was shown to predispose individuals to the use of the other, often leading to concurrent use of both substances. Peer influence and positive expectations regarding e-cigarettes were identified as significant predictors of dual use. Dual vapers exhibited a higher susceptibility to respiratory and systemic symptoms compared to those who exclusively vaped nicotine or cannabis. Moreover, a notable prevalence of psychiatric disorders, such as substance use disorders, anxiety, and depression, was observed in this group. Fruit-flavored e-cigarettes were the most preferred option among dual vapers when using both nicotine and cannabis. Conclusions: Current evidence is insufficient to fully elucidate the long-term impacts of dual vaping on physical and mental health, particularly when compared to individuals who have never vaped. Further studies are needed to gain a more comprehensive understanding of this behavior. Full article

This study of 18–24-year-old young adults (YAs) in Australia who use, or used to use, nicotine vape products (NVPs) sought to explore their experiences when attempting to quit vaping to understand the barriers and identify facilitators of cessation. We analysed data from a survey (n = 532) of 422 YAs who vape and 110 YAs who used to vape, as well as interactive workshops (n = 12) and semi-structured interviews (n = 3), which included 7 YAs using and 8 no longer using NVPs. Social Cognitive Theory informed the data collection, with open-ended questions exploring how personal, environmental and behavioural factors shaped vaping cessation. Qualitative analyses revealed 11 themes shaping vaping cessation, including the normalisation of vaping, easy access and a desire to fit in. Vaping cessation was complicated by using NVPs to manage symptoms of mental ill-health. Additionally, former vapers reported using combustibles to replace vaping, highlighting the risk of health impacts from smoking. Potential support sources included friends and general practitioners, or family doctors. Support service development must consider de-normalising vaping, addressing underlying mental health issues and providing effective campaigns around the health risks of vaping and smoking. The findings highlight the need to invest in vaping cessation, and they can inform the design of vaping cessation programs to better support those trying to quit and ensure the success of their quit attempts.

Background: Cannabis use is associated with an increased risk of coronary heart disease (CHD), including angina pectoris (AP), and myocardial infarction (MI). However, it is not clear whether cannabis use is an independent risk factor of AP and/or MI, because cannabis is often smoked together with tobacco. We investigated whether cannabis is an independent risk factor of MI and whether this risk is similar in cannabis smokers, cannabis vapers, and those who use cannabis edibles. Methods: A systematic review was performed, according to the PRISMA guidelines and using Medline (PubMed), Embase, and Google Scholar as databases. Results: Twenty-two eligible papers were identified. After adjustment for concurrent tobacco use, cannabis smoking remained significantly associated with incidents of MI, with aORs ranging between 1.03 and 5.24, and particularly high aORs in the younger age group. In never-tobacco smokers, frequent cannabis smoking was also associated with a significant MI risk (aOR = 1.88). Frequent and current cannabis use in any form other than smoking (e.g., vaping, but mostly ingestion) was not associated with a significantly increased cardiovascular risk (frequent use: aOR = 1.00 ns; current use: aOR = 1.31 ns). Conclusions: Like tobacco smoking, cannabis smoking may independently provoke MI. Vaping and ingestion of cannabis might be less harmful, probably because absence of combustion prevents exposure to certain toxins in cannabis smoke, including carbon monoxide. Full article

Electronic cigarette (e-cig) use, otherwise known as “vaping”, is widespread among adolescent never-smokers and adult smokers seeking a less-harmful alternative to combustible tobacco products. To date, however, the long-term health consequences of vaping are largely unknown. Many toxicants and carcinogens present in e-cig vapor and tobacco smoke exert their biological effects through epigenetic changes that can cause dysregulation of disease-related genes. Long non-coding RNAs (lncRNAs) have emerged as prime regulators of gene expression in health and disease states. A large body of research has shown that lncRNAs regulate genes involved in the pathogenesis of smoking-associated diseases; however, the utility of lncRNAs for assessing the disease-causing potential of vaping remains to be fully determined. A limited but growing number of studies has shown that lncRNAs mediate dysregulation of disease-related genes in cells and tissues of vapers as well as cells treated in vitro with e-cig aerosol extract. This review article provides an overview of the evolution of e-cig technology, trends in use, and controversies on the safety, efficacy, and health risks or potential benefits of vaping relative to smoking. While highlighting the importance of lncRNAs in cell biology and disease, it summarizes the current and ongoing research on the modulatory effects of lncRNAs on gene regulation and disease pathogenesis in e-cig users and in vitro experimental settings. The gaps in knowledge are identified, priorities for future research are highlighted, and the importance of empirical data for tobacco products regulation and public health is underscored.

Background: While public health efforts have made tobacco smoking near obsolete among adolescents, vaping products are quickly taking their place. With the negative health consequences looming ahead of young vapers, there is a desperate need to curb youth vaping. Adolescents want to be actively engaged in their health which creates space to educate on vaping in this population segment. Methods: From January to May 2023, 35 adolescents aged 11–18 participated in interviews to assess the investigator-developed Teen E-cigarette and Vaping Educational Resource (T-EVER). All the interviews were recorded and transcribed for independent analysis by two study team members. Results: The participants liked the T-EVER, indicating they were engaged in the content. However, some participants wanted more information. The participants wanted health professionals to educate them on vaping but were worried about the potential barriers facing the implementation in community pharmacy settings. Conclusions: Adolescents want to learn about vaping, but there are limited opportunities to do so. The T-EVER is designed to educate youth about vaping. This tool was well received and has the potential to be used by pharmacists as a vaping prevention and cessation intervention. More research is required to discern the true scope of the pharmacist’s role in using an educational tool to address adolescent vaping. Full article

The increase in the popularity and use of electronic cigarettes (e-cigarettes) has consistently risen worldwide and has become associated with adverse health outcomes. This study has identified the attitudes and perceptions of undergraduate students who vape in three universities in Mexico. A cross-sectional study involving 495 participants was conducted using a survey from October to December 2023. Three universities in different states in Mexico collaborated with colleges in Yucatan, Durango, and Nuevo Leon, Mexico. Descriptive statistics include frequencies and percentages, and four logistic regression models were employed. In the sample, 31% and 17.54% of participants reported smoking and vaping, respectively. Students who reported vaping in the last month reported that their first experience with vaping was at an average of 17.3 years of age, and of those, 71.26% (n = 62) reported having vaped for over 100 days, while the remaining 38% reported vaping for between 2 and 100 days. Students from Veracruz and Yucatan began vaping at a younger age than in the central and northern regions. There is a need to educate students about the dangers of the chemicals in the liquids they use, the secondary exposure vapers, and the health dangers they pose. Full article

This study examined how Social Cognitive Theory (SCT) constructs help explain the intention to quit e-cigarettes in young Australian adults aged 18–24 years to inform vaping cessation programs. A cross-sectional survey of young adult vapers (n = 422) between March and the end of May 2023 examined personal, environmental, and behavioural factors of vaping cessation. Hierarchical multiple regression analysis examined the effects of SCT constructs on intention to quit vaping, controlling for covariates. Results found, in our sample consisting of 68% (n = 360) females, 18% (n = 95) males and 14% (n = 77) others, almost two-thirds (59.7%) of participants reported a quit attempt in the last year; with quit attempts being associated with quit intention (p ≤ 0.001). Model 1 (past year quit attempt, gender, educational attainment) accounted for 28.7% of the variance in quit intentions, with the addition of Model 2 SCT constructs adding a further significant 6.3% variance. Self-efficacy (B = 0.164, p ≤ 0.001), benefits (B = −0.106, p = 0.041) and social norms (B = −0.086, p = 0.035) had significant independent associations with quit intention. Findings demonstrate the SCT theoretical framework is suitable for use when developing vaping cessation programs, identifying the SCT constructs as important factors for quit intention. The findings can be used to inform the development of evidence-based vaping cessation programs to encourage vapers to quit and/or better support them in the quitting process. Full article

Little attention has been devoted to understanding the language surrounding e-cigarette use. Researchers employ terms such as users of e-cigarettes or ENDS, but language employed outside scholarly writing is relatively unexamined. Thus, this study examined the language used by college students to refer to people who use e-cigarettes. College students (N = 1037; M_age= 20.67, SD = 3.81; 72.1% female; 69.6% White) at a southern U.S. university responded to the open-ended question: “What do you call a person who uses e-cigarettes?” Of 1086 responses, e-cigarette users’ (n = 591) and nonusers’ (n = 495) responses were examined separately. Although users and nonusers had the same two top terms (“vaper” and “smoker”), a clearer consensus existed among users where “vaper” was most common (51.3%) followed by “smoker” (21.0%). These same terms were endorsed by 37.0% and 31.5% of nonusers, respectively. The third most popular responses of users related to addiction (e.g., “addict”, “fiend”; 8.46%), whereas nonusers’ responses indicated they did not know what to call an e-cigarette user (e.g., “I don’t know”; 7.1%). Users were equally likely to use positive (e.g., “Vape God”) and negative (e.g., “fool”) terms, whereas nonusers were nearly six times more likely to use negative terms. Therefore, it may be useful to capitalize on these language trends in health campaigns as well as develop separate messaging for users vs. nonusers. Full article

Proteases such as neutrophil elastase cleave and activate the epithelial sodium channel (ENaC), causing airway dehydration. Our current study explores the impact of increased protease levels in vapers’ airways on ENaC activity and airway dehydration. Human bronchial epithelial cultures (HBECs) were exposed to bronchoalveolar lavage fluid (BALF) from non-smokers, smokers and vapers. Airway surface liquid (ASL) height was measured by confocal microscopy as a marker of hydration. ENaC cleavage was measured by Western blotting. Human peripheral blood neutrophils were treated with a menthol-flavored e-liquid (Juul), and the resulting secretions were added to HBECs. BALF from smokers and vapers significantly and equally increased ENaC activity and decreased ASL height. The ASL height decrease was attenuated by protease inhibitors. Non-smokers’ BALF had no effect on ENaC or ASL height. BALF from smokers and vapers, but not non-smokers, induced ENaC cleavage. E-liquid-treated neutrophil secretions cleaved ENaC and decreased ASL height. Our study demonstrated that elevated protease levels in vapers’ airways have functional significance since they can activate ENaC, resulting in airway dehydration. Lung dehydration contributes to diseases like cystic fibrosis (CF), chronic obstructive pulmonary disease (COPD) and asthma. Thus, our data predict that vaping, like smoking, will cause airway surface dehydration that likely leads to lung disease. Full article

Taxes on the consumption of certain products have played a key role in public revenue analysis in European countries. This work assesses the differences in tax planning for new non-combustion products across some European territories. Through theoretical analysis, the paper has three distinct aspects. Firstly, we show the taxpayer profile in different countries. Secondly, the study analyzes the risks for the health system and the individual. Thirdly, the design of the national tobacco tax is based on previous experience and planning in Europe. This paper concludes with a case study for different countries: (1) Spain “vapers” and “smokers”, where the analysis is based on micro-data from the European Health Interview Survey 2020. (2) Sweden, with the analysis of snus, shows it as a practice on how to reach economic savings while decreasing economic costs thanks to the nudging of consumers towards better products. The results show taxation and, especially, land taxation should consider differences in planning in the case of new products, such as non-combustion products, given the user per capita income and the potential lower health risks involved.

The prevalence of vaping worldwide is showing an upward trend. This study aimed to determine the factors associated with motivation to quit vaping among vapers in the Federal Territory of Kuala Lumpur, Malaysia, through a cross-sectional, purposive sampling study. Respondents were required to complete a questionnaire consisting of vapers’ sociodemographic questions, habitual behavioral pattern questions, the e-Fagerström Test of Nicotine Dependence, the Glover–Nilsson Smoking Behavioral Dependence Questionnaire, perception questions, motivation to quit questions, and withdrawal symptom questions. A total of 311 vapers participated in this study. The majority of the vapers were male (84.6%), younger (18–25 years) (55.3%), and with monthly income less than RM 4000 (USD 868; 83.9%). The level of motivation to quit vaping was found to have a significant association with the perception of vaping being as satisfying as cigarette smoking (p = 0.006) and mild to very strong nicotine dependence (p = 0.001). Participants who recorded moderate and strong habitual vaping behaviors had lower odds of having high motivation to quit vaping compared to those recording slight habitual behaviors (OR = 0.279, 95%CI(0.110–0.708), p = 0.007 and OR = 0.185, 95%CI(0.052–0.654), p = 0.009, respectively). Factors associated with higher motivation to quit vaping could be explored to gain better understanding of how to increase their motivation level for future quit attempts. Full article
