Conducting tobacco control surveys among schoolchildren in Bangladesh, India and Pakistan: A feasibility study.

Most of the world's 300 million smokeless tobacco (ST) users live in South Asia but ST policies for that region are poorly researched, developed and implemented. Longitudinal studies to understand the uptake and use of ST and smoking, and influences on these, such as health promotion strategies, are lacking. We planned to conduct longitudinal surveys among secondary school students in three countries with the highest ST burden: Bangladesh, India and Pakistan to explore ST and smoking uptake, use and health promoting strategies.

Does perceived vaping addiction predict subsequent vaping cessation behaviour among adults who use nicotine vaping products regularly?

Background: This study aimed to investigate whether perceived vaping addiction is a predictor of quitting nicotine vaping product (NVP) use among adults who have ever smoked and currently vape exclusively or predominantly in four countries: Australia, Canada, the US, and England.

Method: Data analysed (n = 574) came from participants (aged 18 + ) who completed the International Tobacco Control (ITC) Four Country Smoking and Vaping survey in 2018 and again in 2020. Baseline inclusion criteria were: (1) currently not smoking or non-daily smoking; and (2) using NVPs daily/weekly for a period of at least 4 months.

Packaging of disposable vaping products and e-liquids in England, Canada and the United States: A content analysis.

Background And Aims: Vaping product packaging is varied and often features bright colours and novel designs, particularly among recently marketed disposable vapes. This study provides an overview of attributes found on the packaging of popular disposable vapes and e-liquid bottles in England, Canada and the United States (US) and assesses compliance with local packaging regulations.

Design: Content analysis.

Support for banning sale of smoked tobacco products among adults who smoke: findings from the International Tobacco Control Four Country Smoking and Vaping Surveys (2018-2022).

Background: Many people continue to smoke despite strong policies to deter use, thus stronger regulatory measures may be required. In four high-income countries, we examined whether people who smoke would support a total ban on smoked tobacco products under two differing policy scenarios.

Methods: Data were from 14 363 adults (≥18) who smoked cigarettes (≥monthly) and participated in at least one of the 2018, 2020 or 2022 International Tobacco Control Four Country Smoking and Vaping Surveys in Australia, Canada, England and the USA.

Harm perceptions across vaping product features: An on-line cross-sectional survey of adults who smoke and/or vape in the United Kingdom.

Background And Aims: Vaping products are diverse with a wide variety of features, and popular products change rapidly. This study examined the features and types of vaping products that people who smoke and/or vape perceive contribute to the health harms of vaping.

Design, Setting And Participants: This was a cross-sectional survey co-designed with adults who smoked/vaped and pre-registered.

Associations between vaping and self-reported respiratory symptoms in young people in Canada, England and the US.

Background: Prevalence of youth nicotine vaping has increased, heightening concerns around negative health effects. This study aimed to compare self-reported respiratory symptoms among youth by vaping behaviours.

Methods: Participants (n = 39,214) aged 16-19 from the 2020 and 2021 International Tobacco Control Policy Evaluation Project (ITC) Youth Tobacco and Vaping Surveys (Canada, England, US).

Evaluation of a hospital-initiated tobacco dependence treatment service: uptake, smoking cessation, readmission and mortality.

Background: The National Health Service in England aims to implement tobacco dependency treatment services in all hospitals by 2024. We aimed to assess the uptake of a new service, adapted from the Ottawa Model of Smoking Cessation, and its impact on 6-month quit rates and readmission or death at 1-year follow-up.

Methods: We conducted a pragmatic service evaluation of a tobacco dependency service implemented among 2067 patients who smoked who were admitted to 2 acute hospitals in London, England, over a 12-month period from July 2020.

Use of 'Elf Bar' among youth and young adults who currently vape in England: cross-sectional associations with demographics, dependence indicators and reasons for use.

Background And Aims: Elf Bar is currently the leading e-cigarette (vape) brand in Great Britain. This study examined youth and young adults' use of Elf Bar, socio-demographic characteristics and dependence indicators and reasons for use over other brands.

Design: Cross-sectional survey.

Noticing education campaigns or public health messages about vaping among youth in the United States, Canada and England from 2018 to 2022.

Public health campaigns have the potential to correct vaping misperceptions. However, campaigns highlighting vaping harms to youth may increase misperceptions that vaping is equally/more harmful than smoking. Vaping campaigns have been implemented in the United States and Canada since 2018 and in England since 2017 but with differing focus: youth vaping prevention (United States/Canada) and smoking cessation (England).

Support for nicotine reduction in cigarettes: findings from the 2016 and 2020 ITC Four Country Smoking and Vaping Surveys.

Introduction: The USA and New Zealand have sought to establish a product standard to set a maximum nicotine level for cigarettes to reduce their addictiveness. This study examined support for very low nicotine cigarettes (VLNCs) in Australia, Canada, England and the USA between 2016 and 2020.

Methods: Repeated cross-sectional data were analysed from participants who currently smoke, formerly smoked or vaped and/or currently vape in the 2016 (n=11 150) and/or 2020 (n=5432) International Tobacco Control (ITC) Four Country Smoking and Vaping Survey.

How is nicotine vaping product (e-cigarette) use monitored in primary care electronic health records in the United Kingdom? An exploratory analysis of Clinical Practice Research Datalink (CPRD).

Background: Electronic health records (EHRs) could identify long-term health effects of nicotine vaping. We characterised the extent to which vaping is recorded in primary care EHRs in the UK, on a population level.

Methods: We performed descriptive analysis of Clinical Practice Research Datalink (CPRD), primary care electronic health records of 25% of the UK population (~ 16 million patients).

Prognosis of older adults with chronic lymphocytic leukemia: A Surveillance, Epidemiology, and End Results-Medicare cohort study.

Introduction: While prognosis for patients with chronic lymphocytic leukemia (CLL) has improved over time in younger adults, only modest improvements have occurred in older adults. We conducted a descriptive study of prognosis in older adults with CLL.

Materials And Methods: We used data from the Surveillance, Epidemiology, and End Results (SEER)-Medicare database from 2003 to 2016.

Exposure to Tobacco-Specific Nitrosamines Among People Who Vape, Smoke, or do Neither: A Systematic Review and Meta-Analysis.

Introduction: Smoking exposes people to high levels of Tobacco-Specific Nitrosamines (TSNAs), which include potent carcinogens. We systematically reviewed TSNA exposure between people smoking, vaping, and doing neither.

Aims And Methods: Databases were searched between August 2017-March 2022, using vaping-related terms.

Impact of E-liquid Packaging on Vaping Product Perceptions Among Youth in England, Canada, and the United States: A Randomized Online Experiment.

Introduction: Vaping is not risk-free but can help those who smoke to reduce harm to health and stop smoking. However, packaging of vaping products, including e-liquids, appeals to youth and might facilitate vaping among nicotine-naïve people. Standardized packaging of vaping products could moderate the appeal of vaping among youth.

Support Provided by Stop-Smoking Practitioners to Co-users of Tobacco and Cannabis: A Qualitative Study.

Introduction: Co-use of tobacco and cannabis is highly prevalent among cannabis users and is associated with poorer tobacco cessation outcomes. This study explored the barriers and enablers influencing stop-smoking practitioners' ability to provide optimal support to co-users.

Trends in Psychological Distress Among Adults in England, 2020-2022.

Importance: In the last 3 years, people in England have lived through a pandemic and cost-of-living and health care crises, all of which may have contributed to worsening mental health in the population.

Objective: To estimate trends in psychological distress among adults over this period and to examine differences by key potential moderators.

Design, Setting, And Participants: A monthly cross-sectional, nationally representative household survey of adults aged 18 years or older was conducted in England between April 2020 and December 2022.

Marketing claims on the websites of leading e-cigarette brands in England.

Introduction: Exposure to electronic cigarette (EC) marketing is associated with EC use, particularly among youth. In England, the Tobacco and Related Products Regulations and Committee of Advertising Practice (CAP) regulate EC marketing to reduce appeal to youth; however, there are little published data on EC marketing claims used online. This study therefore provides an overview of marketing claims present on the websites of EC brands popular in England.

Efficacy of WeChat-based online smoking cessation intervention ('WeChat WeQuit') in China: a randomised controlled trial.

Background: China has approximately 300 million current smokers, and smoking cessation services are limited. This study aimed to assess the efficacy of a Cognitive Behavioral Theory-based smoking cessation intervention ('WeChat WeQuit') via the most popular social media platform in China, WeChat.

Methods: A parallel, single-blind, two-arm randomised controlled trial was conducted via WeChat between March 19, 2020 and November 16, 2022.

Pattern and prevalence of vaping nicotine and non-nicotine drugs in the United Kingdom: a cross-sectional study.

Objectives: Electronic vaping devices are being used to consume nicotine and non-nicotine psychoactive drugs. We aimed to determine the pattern and prevalence of using vaping devices for nicotine and/or non-nicotine drug administration in the United Kingdom and how these differ by drug type and individual sociodemographic characteristics. We explored reasons for vaping onset and continuation.

Association of Fully Branded and Standardized e-Cigarette Packaging With Interest in Trying Products Among Youths and Adults in Great Britain.

Importance: e-Cigarette vaping among youths and adults has increased in Great Britain. The design of e-cigarette packaging may appeal to youths. Regulations that reduce the appeal of e-cigarettes to youths may deter adult smokers from trying e-cigarettes to help them quit smoking.

A critique of the Australian National Health and Medical Research Council CEO statement on electronic cigarettes.

This paper critically analyses a statement by Australia's National Health and Medical Research Council (NHMRC) on e-cigarettes in May 2022 that will be used to guide national policy. We reviewed the evidence and the conclusions drawn in the NHMRC Statement. In our view, the Statement is not a balanced reflection of the benefits and risks of vaping because it exaggerates the risks of vaping and fails to compare them to the far greater risks of smoking; it uncritically accepts evidence of harms from e-cigarettes while adopting a highly sceptical attitude towards evidence of their benefits; it incorrectly claims that the association between adolescent vaping and subsequent smoking is causal; and it understates the evidence of the benefits of e-cigarettes in assisting smokers to quit.
