  • Characterising ‘Spree Bar’

    Richard J O’connor, Dongmei Li et al.ARTICLETobacco Control2026

    There is limited evidence of widespread uptake of Spree Bar to date. However, its marketing approach and striking mislabeling and coolant ubiquity underscore the need for regulatory vigilance

  • Same brand, same flavour

    Michelle K Page, Noel J Leigh et al.ARTICLETobacco Control2025

  • E-cigarette consumption among youth who vape in Canada, England, New Zealand and the USA

    Makenna N Gomes, Jessica L Reid et al.ARTICLETobacco Control2025

    The findings suggest substantial e-liquid consumption among youth who vape in all four countries

  • Digital footprints of the US e-cigarette market

    Zidian Xie, Alex C Liber et al.ARTICLETobacco Control2025

    Google search trends and social media activities can serve as digital footprints of the e-cigarette market, providing reliable data sources for near-real-time monitoring of the prominence of e-cigarette brands in the marketplace

  • Exposure to Iqos ads and reduced exposure claims, and association with perceived risk from Covid-19 on Iqos purchase and use intentions

    Open AccessAkshika Sharma, Brian V Fix et al.ARTICLEFrontiers in Public Health2024

    Introduction: IQOS was authorized to be marketed as a reduced exposure product by the Food and Drug Administration in October 2020 during the global COVID-19 pandemic. Those who smoke may be more sensitive to reduced exposure marketing claims and may have an increased inclination toward IQOS use. We evaluated the likelihood of trying and purchasing IQOS as a function of exposure to ads, product appeal, and COVID-19 risk perceptions using the orig…

  • Transformation of the tobacco product market in Japan, 2011–2023

    Open AccessK Michael Cummings, A Roberson et al.ARTICLETobacco Control2024

    While many factors may account for the decreased sale of cigarettes in Japan over the past 12 years, the increased sale of HTPs appears to be a factor

  • Awareness and perceived behaviour changes following the New York state vaping flavour ban, 2021–2022

    Open AccessLiane M Schneller, Jessica L Reid et al.ARTICLETobacco Control2024

    Less than one-third of NY youth, regardless of vaping status, reported that an e-cigarette flavour ban was present where they live. Further, most youth who were aware of the ban misunderstood which flavours were restricted and/or that the ban applied to all stores that sold e-cigarettes. Increased enforcement and educational efforts could improve awareness and understanding of the NY e-cigarette flavour ban

  • The effect of survival processing on memory for pictures depends on how memory is tested

    Open AccessStephen A Dewhurst, Rachel J Anderson et al.ARTICLEMemory2023

    Two experiments investigated the effects of survival processing on memory for pictures of objects. In experiment 1, participants were presented with 32 pictures of common objects and rated them for their relevance to a survival scenario, a moving home scenario, or for pleasantness. In a surprise recall test, participants in the survival condition recalled more of the verbal labels of the objects than participants in the moving and pleasantness co…

  • Reasons for Initiation and Regular Use of Heated Tobacco Products among Current and Former Smokers in South Korea

    Open AccessHong Gwan Seo, Steve S Xu et al.ARTICLEInternational Journal of…2023

    South Korea is the world’s second-largest heated tobacco product (HTP) market after Japan. HTP sales in South Korea have increased rapidly since May 2017, accounting for 10.6% of the total tobacco market in 2020. Despite this, little is known as to why HTP consumers who were current and former smokers started using HTPs and used them regularly. We analyzed cross-sectional data for 1815 adults (aged 19+) who participated in the 2020 International …

  • Switching to cigarette brand variants with different filter ventilation levels

    Dana Mowls Carroll, Katelyn Tessier et al.ARTICLETobacco Control2023

    Switching to CBV with lower FV does not appear to increase exposure and may even reduce exposure for some. Additional investigations are recommended to confirm these descriptive findings

  • Heavy metals in ENDS

    Ashleigh C Block, Liane M Schneller et al.ARTICLETobacco Control2023

    The presence of heavy metals only in closed-system products suggests that metals may be leaching from ENDS device parts. Highly variable heavy metal concentrations between ENDS products demonstrate that various product characteristics may affect the degree of leaching and that there is a need for further regulation of these products

  • Still ‘Cool’

    Open AccessMichelle K Page, Emily E Paul et al.ARTICLETobacco Control2023

    While manufacturers have removed menthol descriptors from CA packaging and the menthol ingredient from cigarettes, synthetic cooling chemicals detected in several CA brands suggest that cooling sensory effects may still be sustained. Policymakers must consider both the chemical ingredients themselves and sensory effects in future regulatory approaches

  • Use of Inhaled Nicotine and Cannabis Products among Adults Who Vape Both Substances

    Danielle M Smith, Andrew Hyland et al.ARTICLESubstance Use & Misuse2022

    Background Co-occurring use (co-use) of nicotine and cannabis is common, and represents a broad range of use behaviors, including concurrent use, sequential use, and co-administration. Co-use has primarily been examined through the lens of smoked tobacco and cannabis. Little is known about those who co-use vaped nicotine and cannabis, and the degree to which specific co-use behaviors are associated, based on mode of use and/or substance.Methods W…

  • Trends in Overall and Menthol Market Shares of Leading Cigarette Brands in the USA

    Open AccessErin J Miller Lo, William J Young et al.ARTICLEInternational Journal of…2022

    Many factors can shift cigarette brand preference, and surveillance is an important tactic to inform regulatory strategy. The objective of this study was to identify shifts in top brands' overall and menthol market share from 2014 to 2019. We used data from the National Survey on Drug Use and Health public use datasets, which are a nationally representative, cross-sectional survey of people aged 12+ in the USA. In our analysis of top brands, we a…

  • Changes in product labelling practices and the use of flavouring chemical additives in vaping products after enactment of statewide flavour legislation

    Open AccessMichelle K Page, Ashleigh C Block et al.ARTICLETobacco Control2022

    While a majority of products appeared to remain non-compliant, this study suggests that enactment of legislation on vaping products making expressed or implied flavour claims may result in some manufacturer changes to product labelling including removal of flavour descriptors. However, use of flavouring additives in vaping products appeared not to be impacted by the ban

  • Impact of Canada’s menthol cigarette ban on quitting among menthol smokers

    Open AccessGeoffrey T Fong, Janet Chung‐Hall et al.ARTICLETobacco Control2022

    This pooled analysis of Canada's menthol cigarette ban provides the foundation for estimating the impact of menthol bans in the USA and other countries. Projections suggest that a US menthol cigarette ban would have a substantial impact on increasing quitting

  • Evolution of tobacco products

    Richard J O’connor, Liane M Schneller et al.ARTICLETobacco Control2022

    Declines in cigarette smoking prevalence in many countries and the consolidation of the tobacco industry have prompted the introduction of other forms of nicotine delivery. These include electronic nicotine delivery systems (ENDS), heated tobacco products (HTPs) and oral nicotine products (ONPs). Evolving over time, some of these products now deliver nicotine at levels comparable to cigarettes and may serve as effective substitutes for smokers. H…

  • Over 1 year later

    Olivia A Wackowski, Stefanie K Gratale et al.ARTICLETobacco Control2022

    Despite the passage of time, considerable lack of knowledge and misperceptions about EVALI remain among those who smoke. Our findings suggest the need for continued efforts to promote better understanding of EVALI and appropriate behavioural and policy responses

  • E-cigarette and tobacco product use among NYS youth before and after a state-wide vaping flavour restriction policy, 2020–2021

    Open AccessLiane M Schneller, Karin Kasza et al.ARTICLETobacco Control2022

    Nearly all NYS youth continued to vape flavours that were restricted in NYS. While youth past 30-day vaping prevalence decreased significantly from 2020 to 2021, increased flavour restriction compliance could result in an even greater decrease. Continuous monitoring is important to better understand perceptions, use patterns and access at the individual level, retail level and population level to inform future enforcement and restrictions

  • ‘It’s all the other stuff!’ How smokers understand (and misunderstand) chemicals in cigarettes and cigarette smoke

    Open AccessBill King, Ron Borland et al.ARTICLEPublic Understanding of Science2021

    Many people understand chemicals as entities that do not occur naturally, and which are also invariably toxic. Tobacco control messages liberally use the term ‘chemicals’ to evoke these meanings and create concern among smokers. This may reinforce misunderstandings, potentially leading to smokers making harmful choices. To investigate smokers’ understandings of chemicals, we conducted qualitative research using 18 individual interviews and three …

  • Internal Validity of Two Promising Methods of Altering Temporal Orientation among Cigarette Smokers

    Open AccessRichard J O’connor, Ellen Carl et al.ARTICLEInternational Journal of…2021

    Relapse to smoking continues to be among the most urgent global health concerns. Novel, accessible, and minimally invasive treatments to aid in smoking cessation are likely to improve the reach and efficacy of smoking cessation treatment. Encouraging prospection by decreasing delay discounting (DD) is a new therapeutic target in the treatment of smoking cessation. Two early-stage interventions, delivered remotely and intended to increase prospect…

  • Don’t Know” Responses for Nicotine Vaping Product Features among Adult Vapers

    Open AccessNicholas J Felicione, K Michael Cummings et al.ARTICLEInternational Journal of…2021

    Nicotine vaping products (NVPs) have evolved rapidly, and some vapers have difficulty reporting about their NVP. NVP knowledge may be important for providing accurate survey data, understanding the potential risks of NVP use, and assessing legal and regulated products. This paper examines current vapers who responded "don't know" (DK) regarding their NVP features. Data are from adult daily/weekly vapers in Waves Two (2018, n = 4192) and Three (20…

  • Indicators of dependence and efforts to quit vaping and smoking among youth in Canada, England and the USA

    David Hammond, Jessica L Reid et al.ARTICLETobacco Control2021

    Prevalence of dependence symptoms among young e-cigarette users increased between 2017 and 2019, more so in Canada and the USA compared with England. Dependence symptom prevalence was lower for e-cigarettes than smoking; however, the gap has narrowed over time

  • Risk perceptions and continued smoking as a function of cigarette filter ventilation level among US youth and young adults who smoke

    Dana Mowls Carroll, Katelyn Tessier et al.ARTICLETobacco Control2021

    Youth and young adults who use higher FV cigarettes perceived their brand as less harmful compared with other brands. However, level of FV was not associated with continued smoking

  • Evaluating the impact of menthol cigarette bans on cessation and smoking behaviours in Canada

    Open AccessJanet Chung‐Hall, Geoffrey T Fong et al.ARTICLETobacco Control2021

    Although menthol smokers were most likely to switch to non-menthol cigarettes, the menthol ban was also significantly associated with higher rates of quit attempts and quit success among menthol smokers compared with non-menthol smokers, and may have helped to prevent relapse among menthol smokers who had quit smoking before the ban. Results confirm and extend evaluation of Ontario's menthol ban across provinces covering 83% of the Canadian popul…
