Potential smoke-free dividend across local areas in England: a cross-sectional analysis.

BACKGROUND: The value that might be added to local economies each year through the money that people who smoke tobacco would save if everyone quit smoking is called the 'smoke-free dividend'. This study aimed to estimate the value of the smoke-free dividend across local areas in England, and how it relates to the average income in those areas. METHODS: The study was a cross-sectional descriptive analysis of tobacco expenditure from the Smoking Toolkit Study (STS) matched to income and smoking prevalence data for English local authorities. The STS sample was from 2014 to 2020 and comprised 18 721 adults who smoke cigarettes. Self-reported expenditure estimates from the STS were adjusted for under-reporting. This adjustment aimed to align the total expenditure estimate with figures derived from government tax receipts and national estimates of illicit tobacco use. The smoke-free dividend is calculated as 93% of spending on legal tobacco, which is the percentage estimated to leave the local economy, plus 100% of spending on illicit tobacco. RESULTS: The total dividend in England is estimated to be £10.9 billion each year, which equates to £1776 per person who smokes or £246 per adult regardless of smoking status. The estimated dividend is greater in areas with lower average income, with a correlation coefficient of -0.521 (95% CI -0.629, -0.392) between the average income of local areas and the dividend per adult. CONCLUSIONS: This study has estimated that local economies could gain a substantial dividend if everybody stopped smoking, which is larger in lower income areas, meaning that geographical economic inequalities could be reduced.

Exploring the opinions and potential impact of unflavoured e-liquid on smoking cessation among people who smoke and smoking relapse among people who previously smoked and now use e-cigarettes: findings from a UK-based mixed methods study.

BACKGROUND: Although electronic cigarettes (e-cigarettes) appear to be effective in helping people who smoke to stop smoking, concerns about use of e-cigarettes among young people have led to restrictions on non-tobacco flavoured e-liquids in some countries and some US states. These restrictions could reduce the appeal of these products to non-smoking youth but could have negative consequences for people who smoke or use e-cigarettes. METHODS: In this mixed methods study, we recruited UK adults who smoked or used to smoke and subsequently vaped to explore their opinions of unflavoured e-liquids and their beliefs about how they would be impacted by hypothetical e-liquid flavour restrictions. Participants trialled an unflavoured e-liquid instead of their usual nicotine product for four hours and completed a survey and an online interview. RESULTS: Using Interpretive Phenomenological Analysis and graphically presented data, we found differences in participants' opinions of unflavoured e-liquid. If only unflavoured, tobacco flavoured, and menthol flavoured e-liquids remained on the UK market, some people who smoke or vape may be unaffected, but some may relapse to smoking or continue smoking. Despite most wanting to prevent young people from initiating vaping, participants had varying opinions on whether flavour restrictions would be an effective method. CONCLUSIONS: The findings highlight that people who smoke and vape could be impacted by flavour restrictions in a range of ways, some of which could have a potential adverse impact on harm reduction efforts in the UK (e.g., by making smoking more appealing than vaping).

Effects of electronic cigarette e-liquid flavouring on cigarette craving.

BACKGROUND: E-liquid flavour restrictions may discourage electronic cigarette (e-cigarette) uptake among youth. However, possible unintended consequences may include reduced appeal and effectiveness of e-cigarettes for smoking cessation. Non-tobacco flavours appear to be important for smoking cessation, but how and why are currently unclear. METHODS: We conducted an experimental study in a UK sample of adult daily smokers using an independent groups design (N=84). Participants were randomised to use an e-cigarette with nicotine-containing fruit/sweet-flavoured e-liquid (blackcurrant, strawberry, vanilla, caramel) or unflavoured e-liquid for 1 week. The primary outcomes were average, peak and cue-elicited cigarette craving (the latter was assessed using a cue exposure task). The secondary outcomes were smoking lapse occurrence, enjoyment of the e-cigarette, ease of transitioning from smoking to using an e-cigarette, intentions to continue using an e-cigarette, intentions and motivation to quit smoking, return to smoking, and continuation of e-cigarette use. RESULTS: E-liquid flavouring did not appear to have an effect on average cigarette craving (b 0.18, 95% CI -0.44 to 0.79, p=0.57), peak cigarette craving (b -0.12, 95% CI -0.59 to 0.35, p=0.62) or cue-elicited cigarette craving (b -0.21, 95% CI -3.86 to 3.43, p=0.91). We did not find evidence of a difference in secondary outcomes. CONCLUSIONS: We did not find evidence to suggest that nicotine-containing fruit/sweet-flavoured and unflavoured e-liquids have different effects on cigarette cravings after 1 week of use. Further research is needed to establish if differences emerge over longer periods of exposure and extend to smoking cessation outcomes.

Tobacco-free Nicotine Pouch Use in Great Britain: A Representative Population Survey 2020-2021.

INTRODUCTION: Tobacco-free nicotine pouches are products that are placed between the lip and gum, where they deliver nicotine to users. Little is known about nicotine pouch use in Great Britain since they entered the market in 2019. METHODS: Data came from a monthly representative survey of the adult (≥18 years) population in Great Britain (England, Scotland, and Wales) between November 2020 and October 2021 (n = 25 698). We estimated the weighted prevalence of pouch use, overall and stratified by demographics, smoking status, and other nicotine use. RESULTS: Nicotine pouch use was rare among adults, with a weighted prevalence of just 0.26% (95% compatibility interval [CI] = 0.19-0.35). Prevalence doubled from November 2020 to October 2021 (0.14%-0.32%; prevalence ratio [PR] = 2.22, 95% CI = 1.33-3.70). Pouch use was over four times more common among men than women (0.42% vs. 0.09%; PR = 4.55, 95% CI = 2.27-9.09) but less common in older age groups (p < .001). Pouch use was more prevalent among current smokers (0.87%; PR = 13.60, 95% CI = 5.46-33.89), recent former smokers (0.97%; PR = 15.21, 95% CI = 4.03-57.42), and long-term (>1 year) former smokers (0.24%; PR = 3.71, 95% CI = 1.36-10.15), compared with never smokers (0.06%). Prevalence was also elevated among e-cigarette (1.64% vs. 0.15%; PR = 10.59, 95% CI = 5.74-19.52) and nicotine replacement therapy users (2.02% vs. 0.21%; PR = 9.75, 95% CI = 4.64-20.49). CONCLUSIONS: One in 400 adults in Great Britain use nicotine pouches, but the prevalence increased from 2020 to 2021. IMPLICATIONS: Tobacco-free nicotine pouches were introduced to the market in Great Britain in 2019. We found that while pouch use is currently rare in Great Britain, these products have become more popular over time. Pouch use is largely concentrated among younger and middle-aged men who use other nicotine products and have a history of smoking. Continued monitoring of nicotine pouch use is needed.

Smokeless tobacco products, supply chain and retailers' practices in England: a multimethods study to inform policy.

BACKGROUND: In England, many people of South Asian origin consume smokeless tobacco (ST). ST use can lead to oral cancer, which is disproportionately high in South Asians. Our aims were to assess the compliance of ST product retailers with statutory regulations and to explore the supply chain of ST. METHODS: We undertook a multimethods study between August 2017 and July 2019 in five English boroughs with a high proportion of ethnic South Asians. We purchased ST products and conducted field surveys with ST retailers at point of sale. Qualitative interviews were conducted with ST retailers and suppliers. ST packs were assessed for regulatory compliance, while quantitative and qualitative data triangulated information on retailers' practices and the ST supply chain. RESULTS: We collected 41 unique ST products, which included dry snuff, naswar, gutka, chewing tobacco and zarda. ST products were not registered, and demonstrated low compliance with health warning (14.6%) and packaging (56.1%) requirements. ST availability in surveyed boroughs was high (38.2%-69.7%); dry snuff, naswar and zarda were most commonly available. ST retailers demonstrated limited knowledge of regulations, and one-third were found to advertise ST at point of sale. Qualitative insights revealed illicit supply and distribution networks, as well as ST production in discreet locations. CONCLUSION: ST products are widely available in England, yet non-compliant with statutory regulations. In order to safeguard consumers, in particular ethnic South Asians, stronger efforts are needed to regulate the supply chain of ST at both national and international levels.

Prevalence of waterpipe (Shisha, Narghille, Hookah) use among adults in Great Britain and factors associated with waterpipe use: data from cross-sectional Online Surveys in 2012 and 2013.

INTRODUCTION: We assessed the prevalence and frequency of waterpipe smoking among adults (aged 18+ years) in Great Britain (GB) and determined demographic factors associated with use. METHODS: We used cross-sectional representative population surveys conducted online in 2012 and 2013. A total of 12,436 adults in 2012 and 12,171 in 2013 were recruited from a commercial online survey panel. RESULTS: The prevalence of ever use of waterpipe across both survey years combined was 11.6% (95% confidence interval [CI] = 11.0-12.1). Frequent use (at least once or twice a month) was 1.0% (95% CI = 0.8-1.2) and was similar in both 2012 and 2013. There was some suggestion of increased ever but not frequent use among 18-24-year-olds between survey years. After adjustment for covariates, females had lower odds of ever waterpipe use than males (odds ratio [OR] = 0.71, 95% CI = 0.63-0.79), those in the lowest social grade had lower odds of use compared to those in the highest social grade (OR = 0.43, 95% CI = 0.35-0.54), older people were at much lower odds of ever use than younger people, ever having smoked cigarettes increased odds of ever waterpipe use, and being Asian (OR = 1.84, 95% CI = 1.39-2.45) or of mixed ethnicity (OR = 2.36, 95% CI = 1.64-3.40) increased likelihood of ever use compared to White ethnicity. CONCLUSIONS: Frequent waterpipe smoking was relatively rare in these representative samples of the GB adult population, and prevalence was similar between 2012 and 2013. Continued monitoring and targeted interventions are appropriate.

The perceptions of UK youth of branded and standardized, 'plain' cigarette packaging.

BACKGROUND: Tobacco packaging is an important form of promotion. Standardizing cigarette packages ('plain' packaging) represents a novel tobacco control policy. This study examined perceptions of branded and standardized cigarette packages among British youth. METHODS: Seven hundred twelve youth aged 11-17 completed an online survey. Participants viewed pairs of packages altered using a 3 × 2 factorial design: health warning type (40% text, 40% pictorial or 80% pictorial) × standardized pack colour (white vs. brown). A discrete-choice task was used in which participants selected packs based on attractiveness, taste, tar, health risk, impact of health warning and enticement to start smoking. Participants also compared regular Silk Cut and 'Superslims' Silk Cut packs. Participants completed a final selection task from two standardized and two branded packs. RESULTS: Warning type was significantly associated with all six outcomes: packs with larger pictorial warnings were more likely to be perceived as less attractive, less smooth, greater health risk, higher tar delivery, more effective health warnings and less likely to encourage initiation. The same pattern was found for brown vs. white standardized packages, with the exception of attractiveness and initiation. Compared with the regular Silk Cut pack, the 'Superslims' Silk Cut pack was perceived as significantly more favourable on all six outcomes. Finally, among respondents who selected a pack in the pack selection task, 95.1% selected a branded pack vs. 4.9% who selected a standardized pack. CONCLUSIONS: Increasing the size of pictorial health warnings and standardizing the appearance and shape of packages may discourage smoking initiation among young people.

Estimating the harms of nicotine-containing products using the MCDA approach.

BACKGROUND: An international expert panel convened by the Independent Scientific Committee on Drugs developed a multi-criteria decision analysis model of the relative importance of different types of harm related to the use of nicotine-containing products. METHOD: The group defined 12 products and 14 harm criteria. Seven criteria represented harms to the user, and the other seven indicated harms to others. The group scored all the products on each criterion for their average harm worldwide using a scale with 100 defined as the most harmful product on a given criterion, and a score of zero defined as no harm. The group also assessed relative weights for all the criteria to indicate their relative importance. FINDINGS: Weighted averages of the scores provided a single, overall score for each product. Cigarettes (overall weighted score of 100) emerged as the most harmful product, with small cigars in second place (overall weighted score of 64). After a substantial gap to the third-place product, pipes (scoring 21), all remaining products scored 15 points or less. INTERPRETATION: Cigarettes are the nicotine product causing by far the most harm to users and others in the world today. Attempts to switch to non-combusted sources of nicotine should be encouraged as the harms from these products are much lower.

E-cigarettes: prevalence and attitudes in Great Britain.

INTRODUCTION: Electronic cigarettes (e-cigarettes) are a means of recreational nicotine use that can potentially eliminate the need to smoke tobacco. Little is known about the prevalence of use or smokers' attitudes toward e-cigarettes. This study describes use of and attitudes toward e-cigarettes in Britain. METHODS: Respondents from three surveys were recruited from a panel of adults in Britain. Preliminary online and face-to-face qualitative research informed the development of a smokers' survey (486 smokers who had used e-cigarettes and 894 smokers who had not). Representative samples of adults in Britain were then constructed from the panel for population surveys in 2010 (12,597 adults, including 2,297 smokers) and 2012 (12,432 adults, including 2,093 smokers), generating estimates of the prevalence of e-cigarette use and trial in Great Britain. RESULTS: Awareness, trial, and current use increased between 2010 and 2012; for example, current use more than doubled from 2.7% of smokers in 2010 to 6.7% in 2012. The proportion of ever-users currently using e-cigarettes was around one-third in both years. In 2012, 1.1% of ex-smokers reported current e-cigarette use, and a further 2.7% reported past use. Approximately 0.5% of never-smokers reported having tried e-cigarettes. CONCLUSIONS: While we found evidence supporting the view that e-cigarette use may be a bridge to quitting, we found very little evidence of e-cigarette use among adults who had never smoked. British smokers would benefit from information about the effective use, risks, and benefits of e-cigarettes, as this might enable the use of e-cigarettes to improve public health.

Rapid growth in disposable e-cigarette vaping among young adults in Great Britain from 2021 to 2022: a repeat cross-sectional survey.

AIMS: To estimate recent trends in the prevalence of disposable e-cigarette vaping in Great Britain, overall and across ages, and to measure these trends in the context of changes in smoking and vaping prevalence. DESIGN: The Smoking Toolkit Study, a monthly representative cross-sectional survey. SETTING: Great Britain. PARTICIPANTS: A total of 36 876 adults (≥ 18 years) completed telephone interviews between January 2021 and April 2022. MEASUREMENTS: Current e-cigarette vapers were asked which type of device they mainly use. We estimated age-specific monthly time trends in the prevalence of current disposable e-cigarette use among vapers and inhaled nicotine use (vaping/smoking), smoking and vaping among adults. FINDINGS: From January 2021 to April 2022, there was an 18-fold increase in the percentage of vapers who used disposables, rising from 1.2 to 22.2% [prevalence ratio (PR) = 18.0; 95% compatibility interval (CI) = 9.18-49.0]. Growth in disposable e-cigarette vaping was most pronounced in younger adults (interaction P-value = 0.013): for example, the percentage of 18-year-old vapers using disposables rose from 0.4 to 54.8% (PR = 129; 95% CI = 28.5-4520), while it rose from 2.1 to 10.0% (PR = 4.73; 95% CI = 2.06-23.6) among 45-year-old vapers. However, the overall percentage of people currently using any inhaled nicotine remained stable over time both among all adults (20.0 versus 21.2%; PR = 1.06; 95% CI = 0.92-1.22) and among 18-year-olds (30.2 versus 29.7%; PR = 0.99; 95% CI = 0.80-1.22). In 18-year-olds, vaping prevalence grew (11.3 versus 17.7%; PR = 1.57; 95% CI = 1.12-2.29), and there was imprecise evidence for a decline in smoking (24.5 versus 19.5%; PR = 0.80; 95% CI = 0.63-1.04). In 45-year-olds, there was relatively little change in vaping (PR = 1.08; 95% CI = 0.88-1.33) or smoking prevalence (PR = 1.01; 95% CI = 0.88-1.16). CONCLUSIONS: Use of disposable e-cigarettes in Great Britain grew rapidly between 2021 and 2022, especially among younger adults, but the overall prevalence of inhaled nicotine use was stable over time. Most young adult vapers in Great Britain now use disposable products.

Youth use of e-liquid flavours-a systematic review exploring patterns of use of e-liquid flavours and associations with continued vaping, tobacco smoking uptake or cessation.

BACKGROUND AND AIMS: There is concern that young people may be attracted to e-liquid flavours, prompting long-term vaping in naive users and potentially subsequent tobacco smoking. We aimed to review the use of e-liquid flavours by young people and describe associations with uptake or cessation of both regular vaping and tobacco smoking, adverse effects and subjective experiences. DESIGN: Systematic review, including interventional, observational and qualitative studies reporting on the use of e-cigarette flavours by young people (aged < 18 years). SETTING: Studies published in English language from any country or cultural setting. PARTICIPANTS: Young people and their carers (aged < 18 years). MEASUREMENTS: A meta-analysis was not possible due to substantial heterogeneity, inconsistency in reporting of flavour categorizations and non-interventional study designs; thus, we narratively report findings. FINDINGS: In total, 58 studies were included. The quality of the evidence was extremely low. Most (n = 39) studies were cross-sectional survey designs. In total, 11 longitudinal cohort studies assessed trajectories; eight qualitative studies reported on user experiences. Studies reported views and experiences of a total of 512 874 young people. Both cross-sectional and longitudinal studies suggested that flavours are important for initiation and continuation of vaping. Qualitative evidence shows interest and enjoyment in flavours. There was judged to be insufficient evidence that use of e-liquid flavours specifically is associated with uptake of smoking. No studies found clear associations between flavours and cessation in this population. We found no included reports of adverse effects of flavours. CONCLUSIONS: Flavours may be an important motivator for e-cigarette uptake, but the role of flavours in tobacco smoking uptake or cessation is unclear. The quality of the evidence on use of e-cigarette flavours by young people is low overall.

Reciprocal influences of tobacco use on illicit opioid and alcohol use during the first six-months of specialist addiction treatment.

BACKGROUND: This is the first national study of lagged reciprocal associations between tobacco smoking frequency and change in illicit opioid or alcohol use frequency within six-months of treatment. METHODS: All adults admitted to publicly-funded specialist addiction treatment in England in 2018/19 and enrolled for at least six months for either opioid use disorder (OUD; n = 22,046; 82.4 % of those eligible) or alcohol use disorder (AUD; n = 15,251; 78.8 % of those eligible). Two cross-lagged panel models estimated, separately for OUD and AUD patients, the relationships between smoking at admission and change in main drug over six months, and between main drug use at admission and change in smoking over six months. RESULTS: Within the OUD cohort, illicit opioid use frequency reduced from 17.7 days to 8.0 days and smoking tobacco remained at 18.8 days. After controlling for available covariates, higher smoking frequency at admission was associated with a relative increase in illicit opioid use at six-months (0.02 days [95 % CI 0.00-0.03]). Within the AUD cohort, alcohol use frequency reduced from 21.2 days to 14.4 days while smoking tobacco reduced from 12.6 days to 11.5 days. Higher smoking frequency at admission was associated with a relative increase in alcohol use at six-months (0.03 days [95 % CI 0.02-0.04]) and higher alcohol use frequency at admission was associated with a relative increase in smoking at six-months (0.04 [95 % CI 0.02-0.06]), controlling for available covariates. CONCLUSIONS: Higher smoking frequency at admission is associated with higher illicit opioid and alcohol use frequency after six-months of specialist addiction treatment.

The SPECTRUM Consortium: a new UK Prevention Research Partnership consortium focussed on the commercial determinants of health, the prevention of non-communicable diseases, and the reduction of health inequalities.

The main causes of non-communicable diseases (NCDs), health inequalities and health inequity include consumption of unhealthy commodities such as tobacco, alcohol and/or foods high in fat, salt and/or sugar. These exposures are preventable, but the commodities involved are highly profitable. The economic interests of 'Unhealthy Commodity Producers' (UCPs) often conflict with health goals but their role in determining health has received insufficient attention. In order to address this gap, a new research consortium has been established. This open letter introduces the SPECTRUM ( S haping  Public h Ealth poli Cies  To  Reduce ineq Ualities and har M)Consortium: a multi-disciplinary group comprising researchers from 10 United Kingdom (UK) universities and overseas, and partner organisations including three national public health agencies in Great Britain (GB), five multi-agency alliances and two companies providing data and analytic support. Through eight integrated work packages, the Consortium seeks to provide an understanding of the nature of the complex systems underlying the consumption of unhealthy commodities, the role of UCPs in shaping these systems and influencing health and policy, the role of systems-level interventions, and the effectiveness of existing and emerging policies. Co-production is central to the Consortium's approach to advance research and achieve meaningful impact and we will involve the public in the design and delivery of our research. We will also establish and sustain mutually beneficial relationships with policy makers, alongside our partners, to increase the visibility, credibility and impact of our evidence. The Consortium's ultimate aim is to achieve meaningful health benefits for the UK population by reducing harm and inequalities from the consumption of unhealthy commodities over the next five years and beyond.
