Vaping among adults in England who have never regularly smoked: a population-based study, 2016-24.

BACKGROUND: E-cigarettes are increasingly used by smokers and ex-smokers, often to support smoking cessation, but also among those who have never regularly smoked. The aim of our study is to estimate time trends in vaping prevalence among adults who have never regularly smoked and describe the profile of adult never-regular-smokers who vape. METHODS: In this nationally representative, monthly cross-sectional survey in England, 153 073 participants (aged ≥18 years) were recruited from July, 2016, to April, 2024. 94 107 (61·5%) of the 153 073 participants had never regularly smoked. Logistic regression estimated associations between survey wave and current vaping, overall, and by sociodemographic characteristics and alcohol consumption. FINDINGS: Vaping prevalence among never-regular-smokers was relatively stable up to 2021, at an average of 0·5% (95% CI 0·5-0·6) between July, 2016, and December, 2020; it then increased rapidly, reaching 3·5% (2·8-4·4) in April, 2024. This increase was largely driven by young adults (19·0% [13·9-25·4] among individuals aged 18 years) and those with higher alcohol consumption levels (22·1% [11·7-37·8%] among the heaviest drinkers). By contrast, trends among all adults (including current and former smokers) suggested the rise in vaping prevalence plateaued among all ages by early 2023. In 2023-24, 55·6% (48·2-62·8) of never-regular-smokers who vaped reported vaping daily; 81·7% (75·4-86·7) had been vaping for 6 months or more. The most used devices in 2023-24 were disposables (50·2% [42·9-57·5]) and the most commonly used e-liquids contained 20 mg/mL or more nicotine (44·6% [37·4-52·0]). INTERPRETATION: The number of adults in England who vape but have never regularly smoked rose rapidly between 2021 and 2024, particularly in younger age groups and most of these individuals reported vaping regularly over a sustained period. The public health impacts of this finding will depend on what these people would otherwise be doing: it is likely that some might have smoked if vaping were not an available option (exposing them to more harm), whereas others might not have smoked or vaped.

Associations of close social connections with smoking and vaping: a population study in England.

INTRODUCTION: Studies consistently demonstrate smoking is a socially contagious behaviour, but less is known about the influence of social connections on vaping. This study examined associations between having close social connections who smoke or vape and relevant smoking and vaping outcomes. METHODS: This was a representative cross-sectional survey of adults (≥16y) in England. Participants (n=1,618) were asked how many people they discuss important matters with (i.e., close social connections) and how many of them smoke/vape. We tested associations between (i) smoking and (ii) vaping among close social connections and participants' own smoking and vaping status; harm perceptions of e-cigarettes (among current smokers); attempts and success in quitting smoking (among past-year smokers); and use of e-cigarettes as a smoking cessation aid (among past-year smokers who tried to quit). RESULTS: Adults with ≥1 close social connection who smoke were more likely than those with none to smoke themselves (32.8% vs. 9.4%; ORadj=7.23[95%CI 4.74-11.0]) and had an uncertain lower likelihood to quit (12.2% vs. 19.8%; ORadj=0.46[0.17-1.23]). Those with ≥1 close social connection who vape were more likely than those with none to vape themselves (29.6% vs. 6.3%; ORadj=5.16[3.15-8.43]) and to use e-cigarettes in their most recent attempt to quit (57.0% vs. 27.9%; ORadj=18.0[1.80-181]), and had an uncertain higher likelihood to perceive e-cigarettes as less harmful than cigarettes (30.8% vs. 12.2%; ORadj=2.37[0.82-6.90]). CONCLUSIONS: In England, we replicated well-established associations with smoking and found similar evidence for vaping. People were much more likely to vape and to use e-cigarettes to quit smoking if they had close social connections who vaped. IMPLICATIONS: The cross-sectional design means it is not clear whether smoking/vaping among close social connections influences people to smoke/vape themselves, or whether people who smoke/vape select to form close social connections with others who similarly smoke/vape. Further research is required to establish causality. If the associations we observed are causal, interventions that encourage smokers to switch to vaping may have positive spillover effects on social connections' perceptions of e-cigarettes and use of these products to support smoking cessation.

Roll-your-own tobacco use among people smoking menthol cigarettes in Great Britain, 2020-2023: a population-based survey.

INTRODUCTION: The sale of factory-made cigarettes with menthol as characterising flavour has been prohibited in Great Britain since May-2020. However, menthol accessories like flavoured filters for roll-your-own (RYO) tobacco can be sold legally, possibly undermining the policy. This study aimed to explore the association of RYO and menthol cigarette smoking. METHODS: Data were collected between October-2020 and October-2023 from a monthly population-based cross-sectional survey, with 82,120 adults (18+) living in Great Britain providing complete data. Logistic regression models assessed the association between predominant RYO tobacco use and menthol cigarette smoking, and whether it differed by sociodemographic characteristics, unadjusted and adjusted for age, gender, ethnicity, nation, and socioeconomic position. Time-trends in RYO tobacco use among people smoking menthol cigarettes were modelled over the study period. RESULTS: There has been no clear decrease in menthol cigarette smoking prevalence among people who smoke (~14%) following the ban. Predominant RYO use increased among people smoking menthol cigarettes from 49.6% (95%CI: 42.2-57.0) in October-2020 to 61.9% (95%CI: 57.5-66.0) in June-2022, after which it remained stable. Predominant RYO use was more common among people smoking menthol than non-flavoured cigarettes overall (adjusted odds ratio (ORadj)=1.30, 95%CI: 1.14-1.49) and across demographic subgroups. This association was most pronounced in middle-aged compared with older people (35 vs. 65 years ORadj=1.18, 95%CI: 1.01-1.35), and in ethnic minorities compared with White people (ORadj=1.56, 95%CI: 1.03-2.36). CONCLUSIONS: There was a substantial increase in RYO use among people smoking menthol cigarettes in the first two years after the ban, from approximately 50% to 60%. IMPLICATIONS: The availability of menthol accessories may have undermined the ban on factory-made mentholated cigarettes in Great Britain. Roughly one in seven people who smoke cigarettes still report smoking menthol cigarettes and among these, about two thirds predominantly use roll-your-own tobacco. Since there has been no noteworthy change in the prevalence of menthol cigarette smoking since October-2020, new measures will likely be necessary to achieve a further reduction. For example, menthol accessories could be banned or their advertising and availability heavily restricted.

Examining differences in real-world effectiveness of e-cigarettes for smoking cessation by source of purchase in England: an observational study of different contexts before and after the COVID-19 pandemic.

INTRODUCTION: The effectiveness of e-cigarettes for smoking cessation may differ by source of purchase. The changing influence of self-selection on purchase location caused by COVID-19 pandemic-related vape shop closures means we can examine the association between smoking abstinence e-cigarette use by purchase source and test for moderation of this association by the timing of the pandemic. METHODS: Repeat-cross-sectional nationally representative surveys, conducted between January-2017 and August-2023. Participants (N=1,284; ≥18y, 46.9% women) who made a past-year quit attempt, used an e-cigarette in their most recent attempt, currently vaping and provided data on the purchase source were included. The association between e-cigarette purchase source and continuous abstinence following the most recent quit attempt was assessed with adjusted regression, including an interaction between the timing of pandemic restrictions (March-2020 through January-2022). RESULTS: Overall, 48.1% usually purchasing their e-cigarettes from vape shops, declining from 53.6% pre-pandemic to 40.6% during the pandemic. There was inconclusive evidence that those purchasing from vape shops had greater odds of quitting smoking (ORadj=1.25, 95%CI 0.92-1.76). The association between purchase source and successful quitting did not depend upon whether purchasing occurred before or during the pandemic (F=0.08, pinteraction=0.774; pre-pandemic: ORadj=1.23, 0.79-1.91; and pandemic: ORadj=1.29, 0.81-2.06). CONCLUSIONS: More data are needed to conclusively determine whether purchasing from a specialist vape shop increases smoking cessation. Given the changing influence of self-selection on purchase location caused by the pandemic, the similar associations between purchase source and quit success across both periods suggests it is unlikely an artefact of unmeasured confounding. IMPLICATIONS: It is important to know if where e-cigarettes are purchased can increase their effectiveness for smoking cessation. While we found a positive association between purchasing from a specialist vape shop and abstinence rates, the results were inconclusive. Further studies are required to establish whether purchasing from specialist vape shops improves smoking cessation outcomes compared with other purchase sources.

Willingness to get vaccinated initially and yearly against COVID-19 and its association with vaccine hesitancy, vaccine knowledge and psychological well-being: a cross-sectional study in UK adults.

OBJECTIVES: This study explores the association between vaccine hesitancy, vaccine knowledge and psychological well-being with (1) receipt of/willingness to receive an initial vaccine against COVID-19, and (2) willingness to get vaccinated yearly against COVID-19. The importance of different vaccine attributes (eg, vaccine technology, effectiveness, side effects) to choose a specific COVID-19 vaccine was also assessed. DESIGN: Cross-sectional survey administered during May to June 2021 on vaccine hesitancy, vaccine knowledge, psychological well-being, willingness to receive COVID-19 vaccines, sociodemographics and COVID-19-related factors. SETTING: UK. PARTICIPANTS: A self-selected sample of 1408 adults. OUTCOME MEASURES: Receipt of/willingness to receive COVID-19 vaccine for the first time and yearly. RESULTS: Receipt of/willingness to receive a vaccine against COVID-19 initially and yearly were high (97.0% and 86.6%, respectively). Vaccine hesitancy was negatively associated with receipt of/willingness to receive vaccine initially/yearly (adjusted OR (aOR)=0.09, 95% CI 0.04 to 0.26, p<0.001/aOR=0.05, 95% CI 0.03 to 0.09, p<0.001). Vaccine knowledge and psychological well-being were positively associated with willingness to receive a yearly vaccine (aOR=1.81, 95% CI 1.43 to 2.29, p<0.001 and aOR=1.25, 95% CI 1.02 to 1.51, p=0.014, respectively), and general vaccine knowledge also with receipt of/willingness to receive vaccine initially (aOR=1.69, 95% CI 1.18 to 2.42, p=0.004). Vaccine effectiveness was the most important attribute for participants to choose a specific COVID-19 vaccine. CONCLUSIONS: Improving vaccine knowledge and emphasising vaccine efficacy may minimise vaccine hesitancy and increase COVID-19 vaccine uptake.

Trends in long term vaping among adults in England, 2013-23: population based study.

OBJECTIVE: To examine trends in long term (>6 months) vaping among adults in England. DESIGN: Population based study. SETTING: England. PARTICIPANTS: 179 725 adults (≥18 years) surveyed between October 2013 and October 2023. MAIN OUTCOME MEASURES: Time trends in prevalence of long term vaping using logistic regression, overall and by vaping frequency (daily or non-daily), and main type of device used (disposable, refillable, or pod). RESULTS: The proportion of adults reporting long term vaping increased non-linearly, from 1.3% (95% confidence interval 1.1% to 1.5%) in October 2013 to 10.0% (9.2% to 10.9%) in October 2023, with a particularly pronounced rise from 2021. This rise included an increase in long term daily vaping, from 0.6% (0.5% to 0.8%) to 6.7% (6.0% to 7.4%). Absolute increases in long term vaping were larger among people with a history of regular smoking (current smokers: 4.8% (4.0% to 5.8%) to 23.1% (20.4% to 25.9%); recent former smokers: 5.7% (3.4% to 9.2%) to 36.1% (27.6% to 45.4%); long term former smokers: 1.4% (1.0% to 1.9%) to 16.2% (14.2% to 18.4%)), but an increase also occurred among people who had never regularly smoked (0.1% (0.0% to 0.2%) to 3.0% (2.3% to 3.8%)). Growth was also more pronounced in young adults (eg, reaching 22.7% (19.2% to 26.5%) of 18 year olds v 4.3% (3.6% to 5.2%) of 65 year olds), including among those who had never regularly smoked (reaching 16.1% (11.1% to 22.7%) of 18 year olds v 0.3% (0.1% to 0.6%) of 65 year olds). Between October 2013 and March 2021, most long term vapers mainly or exclusively used refillable electronic cigarettes (2.5% to 3.3% of adults) and few (0.1% of adults) used disposable devices. However, prevalence of long term vaping using disposable devices subsequently rose rapidly, and by October 2023 similar proportions of adults mainly or exclusively used disposable and refillable devices (4.9% (4.2% to 5.7%) and 4.6% (4.0% to 5.3%), respectively). CONCLUSIONS: The prevalence of long term vaping increased substantially among adults in England during 2013-23. Much of this increase occurred from 2021, coinciding with the rise in popularity of disposable e-cigarettes. Half of long term vapers now mainly or exclusively use disposable devices. The growth was concentrated among people with a history of regular smoking, but an increase also occurred among people who never regularly smoked, especially young adults.

Trends in vaping and smoking following the rise of disposable e-cigarettes: a repeat cross-sectional study in England between 2016 and 2023.

Background: There has been a rapid rise in disposable (single-use) e-cigarette vaping among young adults in England since June 2021 (leading to a planned ban on these products). We examined how this has affected population trends in current (i) vaping, (ii) tobacco smoking, and (iii) inhaled nicotine use. Methods: We used data from a nationally-representative monthly repeat cross-sectional survey of adults (≥18) in England (n = 132,252; July-2016-May-2023). Using interrupted time-series analyses (segmented logistic regression), we estimated yearly trends in current tobacco smoking, vaping, and inhaled nicotine use (smoking and/or vaping) before ('pre-disposables') and after June-2021 ('post-disposables'), stratified by age group (18 to 24, 25 to 44, 45 and over). We also examined trends in daily use and in vaping among never-smokers. Findings: Pre-disposables, vaping and smoking prevalence had been stable or declining across all age groups. However, post-disposables, the odds of current vaping increased by 99% per year among 18 to 24-year-olds (odds ratio [OR] = 1.99; 95% confidence interval [CI] = 1.71 to 2.31), compared with 39% (OR = 1.39; 95% CI = 1.26 to 1.52) in 25 to 44-year-olds and 23% (OR = 1.23; 95% CI = 1.12 to 1.35) in those aged 45 or older. Smoking rates continued to decline - albeit modestly - in 18 to 24-year-olds (OR = 0.88, 95% CI = 0.77 to 1.00) and 25 to 44-year-olds (OR = 0.93, 95% CI = 0.86 to 1.00), but increased among those aged 45 or older (OR = 1.12, 95% CI = 1.05 to 1.20). As a result, post-disposables, the overall prevalence of inhaled nicotine use increased across all age groups. Trends were similar for daily use, but post-disposables increases in vaping were greatest among people who had never regularly smoked (e.g., 18 to 24-year-olds: OR = 2.50, 95% CI = 1.82 to 3.43). Interpretation: Since disposable vapes started becoming popular in England, historic declines in nicotine use have reversed. Now, nicotine use appears to be rising, driven primarily by sharp increases in vaping among young people. Smoking declines have been most pronounced in age groups with the largest increases in vaping. Funding: Cancer Research UK.

Secondhand Nicotine Absorption From E-Cigarette Vapor vs Tobacco Smoke in Children.

Importance: With the prevalence of e-cigarette use (vaping) increasing worldwide, there are concerns about children's exposure to secondhand vapor. Objective: To compare nicotine absorption among children who are (1) exposed to secondhand tobacco smoke only or (2) exposed to secondhand vapor only with (3) those exposed to neither. Design, Setting, and Participants: The US Continuous National Health and Nutrition Examination Survey (NHANES) is a repeat cross-sectional survey. Participants are interviewed in their homes and, several days after, visit a mobile examination center to provide biological specimens. This study uses data from a nationally representative sample of US households from 2017 to 2020. Participants were children aged 3 to 11 years with serum cotinine levels incompatible with current firsthand nicotine use (ie, <15 µg/L). The final analysis was conducted on January 9, 2024. Exposures: Reported exposure to secondhand smoke or vapor indoors in the past 7 days (only secondhand smoke, only secondhand vapor, or neither). Covariates included age, sex, ethnicity, family income, body weight, and height. Main Outcomes and Measures: The primary outcome was serum cotinine concentration, an objective biomarker of nicotine absorption. Geometric mean cotinine levels and 95% CIs were calculated using log-normal tobit regression, accounting for the complex survey design and weights. Results: The mean (SD) age of the 1777 children surveyed was 7.4 (2.6) years, 882 (49.6%) were female, and 531 (29.9%) had family incomes below the poverty level. Nicotine absorption, as indexed by serum cotinine level, was highest among children only exposed to secondhand smoke (0.494 µg/L µg/L; 95% CI, 0.386-0.633 µg/L), followed by those exposed only to secondhand vapor (0.081 µg/L; 95% CI, 0.048-0.137 µg/L), equating to 83.6% (95% CI, 71.5%-90.5%; P < .001) lower nicotine absorption. Among children with no reported secondhand exposure, the geometric mean cotinine level was 0.016 µg/L (95% CI, 0.013-0.021 µg/L), or 96.7% (95% CI, 95.6%-97.6%; P < .001) lower than for those with exposure to secondhand smoke. Results were similar after covariate adjustment. Conclusions and Relevance: In this cross-sectional study of US children, nicotine absorption was much lower in children who were exposed to secondhand vapor vs secondhand smoke, but higher than in those exposed to neither. These findings suggest that switching from smoking to vaping indoors may substantially reduce, but not eliminate, children's secondhand exposure to nicotine and other noxious substances.

Impact of Standardised Packaging of Tobacco Products Regulations on cigarette consumption and youth smoking in England: interrupted time-series analysis.

BACKGROUND: In the UK in May 2016, standardised packaging of tobacco products was implemented, including minimum pack sizes of 20 sticks or 30 g loose tobacco. The change was intended to reduce uptake by increasing upfront costs to young people, but there was concern it may unintentionally increase consumption among people smoking. This study aimed to assess whether the introduction of the policy was associated with changes in (1) mean daily factory-made (FM)/roll-your-own (RYO) cigarettes consumption among people smoking predominantly (a) FM and (b) RYO cigarettes; and (2) current smoking prevalence among 16-24-year-olds. METHODS: Data (N=257 929) were from a representative monthly cross-sectional survey of adults (≥16 years) in England, collected between November 2007 and January 2020. Outcome measures were mean daily (FM/RYO) cigarette consumption among those smoking FM/RYO cigarettes, and prevalence of current smoking among 16-24-year-olds. Time-series analyses were conducted using Autoregressive Integrated Moving Average with Exogenous variables (ARIMAX) regression models including a gradual level change starting in June 2017 and ending in May 2018 for cigarette consumption and a step change in June 2016 for prevalence of current smoking. RESULTS: The ARIMAX model was not able to detect a change in mean daily cigarette consumption-for FM (Badj=-0.543, 95% CI -1.381 to 0.296) or RYO (Badj=0.002, 95% CI -0.518 to 0.522) following the implementation of standardised packaging. The unadjusted analysis suggested the implementation of standardised packaging was associated with a small (3%) decrease in smoking prevalence among 16-24-year-olds (Bunadj=-0.031, 95% CI -0.062 to 0.000), but this association was attenuated after adjustment for covariates (Badj=-0.010, 95% CI -0.039 to 0.019). CONCLUSIONS: The implementation of standardised packaging of tobacco products was not associated with a meaningful change in the mean number of FM or RYO cigarettes consumed by people smoking in England, suggesting the larger pack size has not had an unintended consequence of substantially increasing cigarette consumption. However, there was also little evidence that the policy substantially reduced smoking among 16-24-year-olds.

Nicotine strength of e-liquids used by adult vapers in Great Britain: A population survey 2016 to 2024.

BACKGROUND AND AIMS: In March 2024, the UK government announced plans to introduce a Vaping Products Duty that will tax e-liquids based on their nicotine strength. This study examined trends in the nicotine strength of e-liquids used by adult vapers and differences in those currently used across relevant subgroups. DESIGN: Nationally-representative, cross-sectional household survey, July 2016 to January 2024. SETTING: Great Britain. PARTICIPANTS: 7981 adult vapers. MEASUREMENTS: Participants were asked whether the e-cigarette they mainly use contains nicotine (yes/no) and the e-liquid strength (no nicotine, >0-≤ 6, 7-11, 12-19 or ≥20 mg/ml). We also collected information on the main device type used (disposable/refillable/pod), age, gender, occupational social grade, history of ≥1 mental health conditions, smoking status and (among past-year smokers) level of cigarette addiction. FINDINGS: The proportion of vapers in England using high-strength (≥20 mg/ml) e-liquids increased from an average of 3.8% (95% confidence interval [CI] = 2.9-5.0) up to June 2021 to 32.5% (CI = 27.9-37.4) in January 2024 (the vast majority of whom [93.3% in January 2024] reported using exactly 20 mg/ml; the legal limit). This rise was most pronounced among those using disposable e-cigarettes, those aged 18-24 years and all smoking statuses (including never smokers) except long-term (≥1y) ex-smokers. Of those surveyed in 2022-2024 in Great Britain, overall, 89.5% (CI = 88.1-90.8) said they usually used e-cigarettes containing nicotine, 8.7% (CI = 7.5-10.0) used nicotine-free e-cigarettes, and 1.8% (CI = 1.2-2.4) were unsure. The proportion using ≥20 mg/ml was higher among those mainly using disposable (47.9%) compared with pod (16.3%) or refillable (11.5%) devices; never smokers (36.0%), current smokers (28.8%) or recent (<1y) ex-smokers (27.4%), compared with long-term ex-smokers (13.9%); and younger (16-24y; 44.2%) compared with older (≥25y; range 9.4-25.1%) age groups. There were no notable differences across other subgroups of interest. CONCLUSIONS: Use of high-strength nicotine e-liquids in England appears to have increased sharply in recent years. Most adult vapers in Great Britain appear to use e-cigarettes that contain nicotine but different subgroups use different strengths: nicotine strengths tend to be higher among those who mainly use disposable devices and those aged 16-24y, and lower among long-term ex-smokers.

Trends in Daily Cigarette Consumption Among Smokers: A Population Study in England, 2008-2023.

INTRODUCTION: This study aimed to estimate time trends in cigarette consumption among smokers in England between 2008 and 2023 and to explore differences by key potential moderators. AIMS AND METHODS: We used data from 57 778 adult cigarette smokers participating in a nationally representative monthly cross-sectional survey between January 2008 and September 2023. We estimated monthly time trends in mean daily consumption of (1) any, (2) manufactured, and (3) hand-rolled cigarettes among all smokers and by main type of cigarettes smoked, smoking frequency, age, gender, occupational social grade, region, nicotine replacement therapy use, and vaping status. RESULTS: Overall cigarette consumption fell from 13.6 [95% CI = 13.3 to 13.9] to 10.6 [10.5 to 10.8] per day between January 2008 and October 2019 (a 22% decrease), then remained stable up to September 2023. Over this period, the proportion mainly or exclusively smoking hand-rolled cigarettes increased (from 30.6% [29.1%-32.1%] in 2008 to 52.1% [49.7%-54.5%] in 2023). As a result, manufactured cigarette consumption fell by 47%, from 9.5 [9.2-9.8] per day in January 2008 to 5.0 [4.7-5.3] in September 2023, while hand-rolled cigarette consumption increased by 35%, from 4.2 [3.9-4.4] to 5.6 [5.3-5.9], respectively. The decline in overall cigarette consumption was observed across all subgroups, but was greater among non-daily smokers, younger smokers, and those who vaped. CONCLUSIONS: Over the last 15 years, the average number of cigarettes consumed each day by smokers in England has fallen by almost a quarter, but has plateaued since October 2019. There has been a sharp decline in the number of manufactured cigarettes consumed and an increase in the number of hand-rolled cigarettes consumed, as smokers have increasingly shifted towards using hand-rolled tobacco. IMPLICATIONS: While average cigarette consumption in England has fallen over the past 15 years, this declining trend has stalled (and reversed in some population groups) since 2019. The availability of cheap, hand-rolled tobacco appears to be undermining policies that aim to reduce smoking by raising the price of tobacco (eg, through taxation) and could be targeted to reignite the decline in cigarette consumption.

Social smoker identity and associations with smoking and quitting behaviour: A cross-sectional study in England.

BACKGROUND: 'Social smoking' typically occurs predominantly or exclusively in the presence of others who are smoking. Relatively little is known about changes in the prevalence of 'social smoking identity' over time and its association with other smoking-related correlates. METHODS: Data were from the Smoking Toolkit Study, a nationally-representative cross-sectional survey in England. Participants were 26,774 adults who currently smoked or had quit in the past year, surveyed between February-2014 and April-2021. We estimated the proportion identifying as having a social smoking identity, changes over time, and associations with smoking in social situations, cigarette dependence, motivation to stop, quit attempts and success. RESULTS: Of adults who currently smoked or had quit in the past year, 34.0% (95% Confidence Interval (CI)=33.5-34.6) identified as having a social smoking identity. There was a near linear increase in this proportion from 31.9% (95%CI=29.7-34.2) in February-2014 to 36.5% (95%CI=34.1-38.9) in April-2021. Adults who currenty smoked identifying as having a social smoking identity were less cigarette dependent (adjusted B=0.34, 95%CI=0.31-0.37) and more motivated to stop (aOR=1.20, 95%CI=1.15-1.26) than those who did not. Adults who currently smoked or had quit in the past year identifying as having a social smoking identity reported more smoking in social situations (aOR=6.45, 95%CI=6.13-6.80) and past-year quit attempts (aOR=1.22, 95%CI=1.14-1.30) than those who did not. Quit success was not associated with having a social smoking identity among adults who currently smoked or had quit in the past year and who had attempted to quit (aOR=0.90, 95%CI=0.79-1.02). CONCLUSIONS: An increasing proportion, over a third, of adults who currently smoked or had quit in the past year in England identify as having a social smoking identity. Despite being associated with lower dependence, greater motivation to quit and more quit attempts, social smoking identity is not associated with greater quit success, suggesting a complex interplay between identity and smoking-related behaviours.

Characterising smoking and nicotine use behaviours among women of reproductive age: a 10-year population study in England.

BACKGROUND: Tobacco smoking affects women's fertility and is associated with substantial risks of adverse pregnancy outcomes. This study explored trends by socioeconomic position in patterns of smoking, use of non-combustible nicotine products, and quitting activity among women of reproductive age in England. METHODS: Data come from a nationally representative monthly cross-sectional survey. Between October 2013 and October 2023, 197,266 adults (≥ 18 years) were surveyed, of whom 44,052 were women of reproductive age (18-45 years). Main outcome measures were current smoking, vaping, and use of nicotine replacement therapy (NRT), heated tobacco products (HTPs), and nicotine pouches; mainly/exclusively smoking hand-rolled cigarettes and level of dependence among current smokers; past-year quit attempts among past-year smokers; and success of quit attempts among those who tried to quit. We modelled time trends in these outcomes, overall and by occupational social grade (ABC1 = more advantaged/C2DE = less advantaged). RESULTS: Smoking prevalence among women of reproductive age fell from 28.7% [95%CI = 26.3-31.2%] to 22.4% [19.6-25.5%] in social grades C2DE but there was an uncertain increase from 11.7% [10.2-13.5%] to 14.9% [13.4-16.6%] in ABC1. By contrast, among all adults and among men of the same age, smoking prevalence remained relatively stable in ABC1. Vaping prevalence among women of reproductive age more than tripled, from 5.1% [4.3-6.0%] to 19.7% [18.0-21.5%], with the absolute increase more pronounced among those in social grades C2DE (reaching 26.7%; 23.3-30.3%); these changes were larger than those observed among all adults but similar to those among men of the same age. The proportion of smokers mainly/exclusively smoking hand-rolled cigarettes increased from 40.5% [36.3-44.9%] to 61.4% [56.5-66.1%] among women of reproductive age; smaller increases were observed among all adults and among men of the same age. Patterns on other outcomes were largely similar between groups. CONCLUSIONS: Among women of reproductive age, there appears to have been a rise in smoking prevalence in the more advantaged social grades over the past decade. Across social grades, there have been substantial increases in the proportion of women of reproductive age who vape and shifts from use of manufactured to hand-rolled cigarettes among those who smoke. These changes have been more pronounced than those observed in the general adult population over the same period.

Intersection of gambling with smoking and alcohol use in Great Britain: a cross-sectional survey in October 2022.

OBJECTIVES: Gambling is associated with cigarette smoking and alcohol consumption. We explored the intersection of gambling across all risk levels of harm with smoking and alcohol use among adults in Great Britain. DESIGN: A nationally representative cross-sectional survey in October 2022. SETTING: Great Britain. PARTICIPANTS: A weighted total of 2398 adults (18+ years). OUTCOME MEASURES: We examined the prevalence of past-year gambling and, among those reporting gambling, assessed the associations between the outcome of any risk of harm from gambling (scoring >0 on the Problem Gambling Severity Index) and the binary predictor variables of current cigarette smoking and higher risk alcohol consumption (AUDIT-C score≥4). We also explored data on weekly expenditure on gambling with smoking and alcohol use among those categorised at any-risk of harm from gambling. RESULTS: Overall, 43.6% (95% CI 41.2% to 45.9%) of adults gambled in the past year. Among these, 7.3% (95% CI 5.3% to 9.3%) were classified at any-risk of harm from gambling, 16.0% (95% CI 13.2% to 18.8%) were currently smoking and 40.8% (95% CI 37.2% to 44.4%) were drinking at increasing and higher risk levels. There were no associations between any risk of harm from gambling and current smoking (OR adjusted=0.80, 95% CI 0.35 to 1.66) or drinking at increasing and higher risk levels (OR adjusted=0.94, 95% CI 0.52 to 1.69), respectively. Analyses using Bayes factors indicated that these data were insensitive to distinguish no effect from a range of associations (OR=95% CI 0.5 to 1.9). The mean weekly spend on gambling was £7.69 (95% CI £5.17 to £10.21) overall, £4.80 (95% CI £4.18 to £5.43) among those classified as at no risk and £45.68 (95% CI £12.07 to £79.29) among those at any risk of harm from gambling. CONCLUSIONS: Pilot data in a population-level survey on smoking and alcohol use yielded similar estimates to other population-level surveys on gambling participation and at-risk gambling. Further data are needed to elucidate the intersections more reliably between gambling, smoking and alcohol use and inform population-level approaches to reduce harm.

'Stopping the start': support for proposed tobacco control policies - a population-based survey in Great Britain 2021-2023.

OBJECTIVES: This study assessed public support for four proposed tobacco control policies in Great Britain: (1) Raising the sales age of tobacco by 1 year every year (Smokefree Generation); (2) Raising the sales age of tobacco from 18 years to 21 years; (3) Providing prescription e-cigarettes as smoking cessation aids to adults who smoke; (4) Restricting e-cigarette advertising to prevent youth uptake. DESIGN: Repeat cross-sectional population-based survey weighted to match the population of Great Britain. SETTING: The survey was conducted in England, Scotland and Wales in September 2021, October 2022 and October 2023. PARTICIPANTS: 6541 adults living in Great Britain. MAIN OUTCOME MEASURES: Support for each policy and year and prevalence ratios (PRs) comparing support between years and subgroups. RESULTS: The most popular policy each year was restricting e-cigarette advertising (74%/79%/85%), followed by raising the sales age to 21 years (50%/58%/64%), providing prescription e-cigarettes (45%/44%/47%) and Smokefree Generation (34%/44%/49%). The largest increases were for policies about the age of sale (Smokefree Generation: 2021/2022 PR=1.28, 95% CI 1.18 to 1.40, 2022/2023 PR=1.12, 95% CI 1.04 to 1.20; raising the age to 21 years: 2021/2022 PR=1.16, 95% CI 1.09 to 1.23, 2022/2023 PR=1.11, 95% CI 1.05 to 1.17). Only 30% opposed Smokefree Generation in 2023 down from 41% in 2021. CONCLUSIONS: Support for each policy increased each year, except for providing prescription e-cigarettes. Restricting e-cigarette advertising was the most popular policy, while support for age of sale policies, in particular for a Smokefree Generation, grew most. TRIAL REGISTRATION: The study protocol was published on the Open Science Framework (https://osf.io/46z2c/) prior to starting the analysis.

Impact of the disruption in supply of varenicline since 2021 on smoking cessation in England: A population study.

BACKGROUND AND AIMS: Varenicline is one of the most effective smoking cessation treatments. Its supply in England was disrupted in July 2021 due to nitrosamine impurities found by its supplier, Pfizer. This study measured the impact of this disruption on smoking cessation in England. DESIGN, SETTING AND PARTICIPANTS: The study used repeated cross-sectional surveys conducted monthly, from June 2018 to December 2022. Set in England, it comprised a total of 3024 adults who reported smoking during the past year and had made at least one serious attempt to quit in the past 6 months. MEASUREMENTS: Generalized additive models analyzed the association of the varenicline supply disruption with the trend in self-reported varenicline use in the most recent quit attempt. We used these results to estimate the population-level impact of the disruption on smoking cessation. FINDINGS: Before July 2021, the proportion of past 6-month quit attempts using varenicline was stable at approximately 3.9% [risk ratio (RR)trend = 1.034, 95% confidence interval (CI) = 0.823-1.298]. The trend in varenicline use has changed sharply since the supply disruption (RRΔtrend = 0.297, 95% CI = 0.120-0.738), with prevalence falling by 69.3% per year since; from 4.1% in June 2021 to 0.8% in December 2022. Convergently, National Health Service general practitioner prescribing data reported that just 0.1% of prescriptions for smoking cessation treatments in December 2022 were for varenicline. Assuming that varenicline does not return to the market, we estimate that this could result in ~8400 fewer people stopping smoking for at least 6 months, ~4200 fewer long-term ex-smokers and ~1890 more avoidable deaths each year. CONCLUSIONS: In England, the disruption in supply of varenicline since 2021 has coincided with a substantial fall in the use of varenicline in attempts to quit smoking.

Are People More Likely to Vape or Smoke Indoors? A Population Survey of Adults in England.

BACKGROUND: Increasingly, people smoke cigarettes outdoors and avoid exposing bystanders to harm. People may not have the same motivation to vape outdoors since e-cigarettes, unlike cigarettes, do not create side stream emissions and exhaled aerosol contains fewer toxicants than secondhand smoke. This study aims to estimate the prevalence and correlates of vaping and smoking indoors among adults in England. AIMS AND METHODS: Data came from the Health Survey for England 2019, a cross-sectional household survey. Adults who vape or smoke (N = 1530) were asked whether they had vaped or smoked indoors inside the home, car, or other places within the past 7 days. Logistic regression was used to estimate prevalence and key correlates of indoor use, including age, sex, presence of adults/children in home, housing tenure, and nicotine dependence. RESULTS: People who exclusively vaped were much more likely to use their product indoors than those who exclusively smoked (87.0% vs. 52.0%; odds ratio [OR] = 6.16, 95% confidence interval [CI] = 4.09 to 9.28). Similarly, people who dual used had higher odds of vaping than smoking indoors (62.1% vs. 44.3%; OR = 3.76, 95% CI = 2.06 to 6.84). The preference for vaping over smoking indoors was found across different locations, including at home and in cars. Those who were older, highly dependent on nicotine, and lived alone were most prone to use any product indoors. While housing tenure was not strongly associated with vaping indoors, those living in social housing were much more likely to smoke indoors than homeowners. CONCLUSIONS: Adults in England are much more likely to vape than smoke indoors. Age, nicotine dependence, and living alone are strongly associated with both behaviors. IMPLICATIONS: Our results show that people have a strong preference for vaping over smoking indoors, including in the home. Given the high prevalence of vaping indoors, policy makers, landlords, and businesses must weigh up the ethics, benefits, and harms of extending smoke-free laws to include e-cigarettes.

Trends in Exclusive Non-Cigarette Tobacco Smoking in England: A Population Survey 2013-2023.

INTRODUCTION: The UK Government intends to implement a "smokefree generation" policy prohibiting the sale of all tobacco products to people born after 2008. National surveys provide comprehensive data on cigarette smoking, but little is known about patterns of non-cigarette tobacco smoking across key population groups. AIMS AND METHODS: Using data from a nationally representative cross-sectional survey of adults in England, collected monthly between September 2013 and September 2023 (n = 196 721), we estimated time trends in exclusive non-cigarette tobacco (eg, cigar/pipe/shisha) smoking prevalence, overall and by age, gender, occupational social grade, region, ethnicity, and vaping status. Interviews were conducted face-to-face until March 2020 and via telephone thereafter. RESULTS: From September 2013 to September 2023, there was a non-linear increase in exclusive non-cigarette tobacco smoking prevalence (from 0.36% to 1.68%; prevalence ratio = 4.72 [95% CI = 3.43-6.48]). Prevalence was relatively stable up to February 2020 (at an average of 0.46%), then increased sharply at the start of the COVID-19 pandemic (at the same time as survey methods changed), to 0.90% (0.82%-0.99%) in March 2020. This was followed by a steadier rise, peaking at 1.97% in May 2022, before falling slightly to 1.68% by September 2023. In 2022/2023, 1 in 10 smokers (10.8% [9.64%-12.0%]) exclusively used non-cigarette tobacco. The rise in prevalence was observed across all subgroups but was most pronounced among younger adults (eg, reaching 3.21% of 18-year-olds vs. 1.09% of 65-year-olds). Prevalence was consistently higher among men and current vapers. CONCLUSIONS: Although exclusive use of non-cigarette combustible tobacco remains rare among adults in England, it has increased in recent years, particularly among younger ages. As of September 2023, there were approximately 772 800 adult exclusive non-cigarette tobacco smokers in England; around five times more than a decade earlier. IMPLICATIONS: The proportion of adults in England who do not use cigarettes at all but smoke other combustible tobacco products has increased substantially in recent years, with a particularly pronounced rise among young people. The inclusion of non-cigarette combustible tobacco products under the proposed "smokefree generation" policy is therefore likely to be important for achieving the greatest reduction in youth uptake of tobacco smoking, as it would ensure young people who are unable to legally buy cigarettes do not buy other combustible tobacco products that are similarly harmful to health.

Smoking prevalence and purchasing of menthol cigarettes since the menthol flavour ban in Great Britain: a population-based survey between 2020 and 2023.

BACKGROUND: Menthol cigarettes have been banned in Great Britain (GB) since May 2020. Still, menthol accessories and unlabelled cigarettes perceived as mentholated are available, and people can buy menthol cigarettes overseas or illicitly. This study assessed: trends in smoking menthol cigarettes among all adults and 18-24-year-olds in GB between October 2020 and March 2023; trends in and differences between England, Scotland and Wales during the same period and purchase sources among people smoking menthol versus non-flavoured cigarettes. METHODS: Population-weighted data were from a monthly cross-sectional survey of adults in GB. Among people smoking cigarettes, we calculated the proportion smoking menthol cigarettes across all adults and 18-24-year-olds, and prevalence ratios (PR) between the first and last quarter. We also calculated the proportions of people smoking menthol/non-flavoured cigarettes by purchase source (including illicit sources). RESULTS: In the first quarter, 16.2% of adults smoking cigarettes reported menthol cigarette smoking with little to no decline throughout the study (PR 0.85, 95% CI 0.71 to 1.01), while it declined among 18-24-year-olds (PR 0.75, 95% CI 0.63 to 0.89). The prevalence of menthol cigarette smoking fell by two-thirds in Wales (PR 0.36, 95% CI 0.19 to 0.62) but remained relatively stable in England (PR 0.88, 95% CI 0.72 to 1.06) and Scotland (PR 0.94, 95% CI 0.59 to 1.53). The main purchasing sources were licit (93.9%), 14.8% reported illicit sources and 11.5% cross-border purchases, without notable differences from people smoking non-flavoured cigarettes. CONCLUSIONS: Roughly one million adults in GB still smoke menthol cigarettes and, with the exception of Wales and young people, there were no noteworthy changes in the post-ban period. There was no indication that the overall persistence of menthol smoking was driven by illicit purchases.
