Project description:PurposeThe tobacco and nicotine market is diversifying. Implications for public health will depend on trends in use, including overall use, and who is using these products. This study examined differences over time (2017-2019), across countries (Canada, England, the United States (US)), and by smoking and vaping, in use of other tobacco/nicotine products and overall use.MethodsThe study includes online repeat cross-sectional surveys of youth aged 16-19 years in Canada (N = 11,714), England (N = 11,170), US (N = 11,838) in 2017, 2018, and 2019. Past 30-day use of tobacco/nicotine products (any, cigarette, e-cigarette, other combusted [cigars/cigarillos/waterpipe], other non-combusted [smokeless tobacco/nicotine replacement therapies) were examined by country, year, and, for other combusted and non-combusted products, past 30-day cigarette smoking and vaping. Use of emerging products (IQOS, nicotine pouches) was explored in 2018-2019.ResultsFrom 2017 to 2019, use of any product increased in Canada (17.1%-23.2%, AOR = 1.07 [95% CI = 1.04-1.09]) and the US (18.0%-24.0%, AOR = 1.06 [1.04-1.09]) but not England (20.8%-21.7%, AOR = 1.01 [.99-1.03]). Use of other combusted products (cigars/cigarillos/waterpipe) showed little change (Canada: 8.1%-7.8%; England: 6.3%-7.3%; US: 8.6%-8.5%; p ≥ .151). Use of other non-combusted products (smokeless/nicotine replacement therapies) increased in all countries (Canada: 1.5%-3.2%, AOR = 1.02 [1.01-1.02]; England: 1.4%-2.6%, AOR = 1.02 [1.01-1.03]; US: 3.3%-4.9%, AOR = 1.02 [1.01-1.02]). Vaping increased in all countries (Canada: 8.4%-17.8%; England: 8.7%-12.6%; United States: 11.1%-18.5%; all p < .001). Smokers and vapers reported greater use of other combusted and non-combusted products than those who neither smoked/vaped (p < .001). Emerging product use was rare (≤1.5%).ConclusionsYouth past 30-day tobacco and nicotine product use increased from 2017 to 2019 in Canada and the United States, largely due to increases in vaping and other non-combusted products. "Other" tobacco/nicotine products were used predominantly by youth who smoked cigarettes and/or vaped.

Project description:BackgroundPreventing uptake of nicotine products among youth remains a central objective of tobacco control policy. Comparing trends in the use of nicotine across countries provides an opportunity to identify emergent product trends and to evaluate 'natural experiments' in policies.MethodsRepeat cross-sectional data were analysed from eight waves of the International Tobacco Control Youth Tobacco and Vaping Survey, conducted between 2017 and 2022. Non-probability samples of youth aged 16-19 years in Canada, England and the USA (N=104 473) completed online surveys including measures on vaping, smoking and use of other nicotine products. This paper summarises findings across the 5-year period of the study, as part of a comprehensive report on key indicators of youth vaping in the three countries.ResultsThe youth nicotine market has rapidly evolved across the three countries, with different patterns of combustible and non-combustible product use in Canada, the USA and England. These changes are primarily attributable to trends in youth vaping: following declines during the initial COVID-19 pandemic period, by 2022, vaping prevalence neared pre-pandemic levels in the USA and Canada, and reached record highs in England. Notable shifts also occurred in the types of vaping products used by youth, including increased use of disposable, nicotine salt-based products. Additional findings are reported on a range of policy-relevant indicators, including for vaping products, promotions and purchasing.ConclusionsPatterns of nicotine use among youth have rapidly evolved in recent years due to the proliferation of nicotine products, the COVID-19 pandemic and the emerging impact of policy measures.

Project description:IntroductionThe current study sought to examine trends in indicators of dependence for youth vaping and smoking during a period of rapid evolution in the e-cigarette market.Aims and methodsData are from repeat cross-sectional online surveys conducted between 2017 and 2022 among youth aged 16-19 in Canada, England, and the United States (US). Participants were 23 145 respondents who vaped and/or smoked in the past 30 days. Four dependence indicators were assessed for smoking and vaping (perceived addiction, frequent strong urges, time to first use after waking, days used in past month) and two for vaping only (use events per day, e-cigarette dependence scale). Regression models examined differences by survey wave and country, adjusting for sex, age, race, and exclusive/dual use.ResultsAll six indicators of dependence increased between 2017 and 2022 among youth who vaped in the past 30 days (p < .001 for all). For example, more youth reported strong urges to vape at least most days in 2022 than in 2017 (Canada: 26.5% to 53.4%; England: 25.5% to 45.4%; US: 31.6% to 50.3%). In 2017, indicators of vaping dependence were substantially lower than for smoking; however, by 2022, youth vaping was associated with a greater number of days used in the past month (Canada, US), shorter time to first use (all countries), and a higher likelihood of frequent strong urges (Canada, US) compared to youth smoking.ConclusionsFrom 2017 to 2022, indicators of vaping dependence increased substantially. By 2022, vaping dependence indices were comparable to those of smoking.ImplicationsIndicators of vaping dependence among youth have increased substantially since 2017 to levels that are comparable to cigarette dependence among youth who smoke. Future research should examine factors underlying the increase in dependence among youth who vape, including changes to the nicotine profile and design of e-cigarette products.

Project description:BackgroundThe e-cigarette market has rapidly evolved, with a shift towards higher nicotine concentration and salt-based products, such as JUUL; however, the implications for youth vaping remain unclear.MethodsRepeat cross-sectional online surveys were conducted in 2017, 2018 and 2019, with national samples of youth aged 16-19 years recruited from commercial panels in Canada (n=12 018), England (n=11 362) and the USA (n=12 110). Regression models examined differences between countries and over time in the types of e-cigarette products used (design and nicotine content), reasons for using brands and differences in patterns of use, sociodemographics and dependence symptoms by brand/nicotine content.ResultsIn 2019, the use of pod- or cartridge-style e-cigarettes was greater in Canada and the USA than England, with Smok and JUUL the leading brands in all countries. In 2019, youth vapers in England were less likely to report using e-cigarettes with ≥2% nicotine (12.8%) compared with Canada (40.5%; adjusted OR (AOR)=4.96; 95% CI 3.51 to 7.01) and the USA (37.0%; AOR=3.99, 95% CI 2.79 to 5.71) and less likely to report using nicotine salt-based products (12.3%) compared with Canada (27.1%; AOR=2.77, 95% CI 1.93 to 3.99) and the USA (21.9%; AOR=2.00, 95% CI 1.36 to 2.95). In 2019, self-reported use of products with higher nicotine concentration was associated with significantly greater frequency of vaping, urges to vape and perceived vaping addiction (p<0.05 for all).ConclusionsThe use of high-nicotine salt-based products is associated with greater symptoms of dependence, including JUUL and other higher-nicotine brands. Greater use of high-nicotine salt-based products may account for recent increases in the frequency of vaping among youth in Canada and the USA.

Project description:ImportanceLittle is known about temporal trends in children's well-being and how the COVID-19 pandemic may have influenced the well-being of young Australians. Certain demographic groups may be more vulnerable to experiencing declines in well-being.ObjectiveTo examine well-being trends over 6 consecutive years among South Australian students and explore the influence of sociodemographic characteristics.Design, setting, and participantsLongitudinal analyses of annual (2017 to 2022) cross-sectional data of students in grades 4 through 9 (n = 40 392 to 56 897 per year) attending South Australian government schools from the Well-being and Engagement Collection (WEC) census.ExposuresCalendar year (2017-2022) and sociodemographic characteristics (sex, school grade, parental education, language spoken at home, residential region) from school enrollment records.Main outcomes and measuresStudents self-reported life satisfaction, optimism, happiness, cognitive engagement, emotional regulation, perseverance, worry, and sadness.ResultsOver 6 years (2017 to 2022), a total of 119 033 students (mean [SD] age, 12.1 y; 51.4% male) participated in this study. Most well-being measures declined over time, with consistent worsening of well-being from 2020 onward. For example, compared with 2017, sadness was 0.26 (95% CI, 0.25-0.27) points higher in 2020 (standardized mean difference [SMD], 0.27) and remained elevated by more than 0.26 points (SMD, 0.27) in 2021 and 2022. At almost every time point, greatest well-being was reported by students of male sex (except cognitive engagement and perseverance), in earlier school grades, with highest parental education, speaking a language other than English at home, and residing in outer regional and remote settings (for satisfaction, optimism, and emotional regulation). Sociodemographic differences in well-being were generally consistent over time; however, sex differences widened from 2020 for all indicators except cognitive engagement and perseverance. For example, between 2017 and 2022, sadness increased by 0.27 (95% CI, 0.25-0.29) more points among females than males (SMD, 0.28).Conclusions and relevanceIn this longitudinal analysis of annual census data, there were downward trends in students' well-being, especially since 2020. The largest sociodemographic disparities were observed for students of female sex, those in later school grades, and those with lowest parental education. Urgent and equitable support for the well-being of all young people, particularly those facing disparity, is imperative.

Project description:IntroductionThe 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 methodsUsing 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.ResultsFrom 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.ConclusionsAlthough 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.ImplicationsThe 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.

Project description:BackgroundWe examined whether the implementation of electronic cigarette (e-cigarette) policies at the state level (e-cigarette-inclusive smoke-free (ESF) policies, excise taxes on e-cigarettes and raising tobacco legal purchasing age to 21 years (T21)) affected recent upward trends in youth e-cigarette use.MethodsData were from participants from 34 US states who completed the Youth Risk Behavior Survey (YRBS) state surveys in 2017 and 2019 (n=278 271). States were classified as having or not having ESF policies, any e-cigarette excise tax and T21 policies by 1 January 2019. Participants reported ever, past 30-day and frequent (≥20 days) e-cigarette use; past 30-day combustible cigarette smoking; and age, sex and race/ethnicity. Weighted multivariable logistic regression models assessed whether changes in e-cigarette use over time differed by policy status, adjusting for participants' demographics and combustible cigarette smoking.ResultsPrevalence of ever and past 30-day youth e-cigarette use in states with ESF policies decreased during 2017-2019, while the prevalence of these measures in states without ESF policies increased. States with T21 policies showed non-significant changes in prevalence of ever and past 30-day youth e-cigarette use, whereas states without T21 policies showed significant increases in ever and past 30-day youth e-cigarette use. States with ESF and T21 policies showed slower increases in youth frequent e-cigarette use. E-cigarette excise taxes were not associated with decreasing prevalence of youth e-cigarette use.ConclusionsState-level ESF and T21 policies could be effective for limiting growth of youth e-cigarette use despite an overall national increase. Higher e-cigarette excise tax rates may be needed to effectively reduce youth e-cigarette use.

Project description:ImportanceMenthol cigarettes were prohibited in England in May 2020 and nationally in Canada in October 2017 but remain permitted in the US. Evidence on the outcomes of menthol cigarette bans among youth outside of Canada, and the characteristics of youth smokers, is lacking.ObjectivesTo evaluate the outcomes of menthol cigarette bans on youth menthol cigarette smoking and to characterize youth menthol cigarette smokers in terms of demographics and cigarette consumption and dependence.Design, setting, and participantsThis survey study uses data from online repeat cross-sectional International Tobacco Control Youth Tobacco and Vaping Surveys conducted in 2018, 2019, February 2020, and August 2020. Participants included past 30-day smokers aged 16 to 19 years. Data analysis was performed from March 2021 to January 2022.Main outcomes and measuresUsually smoke a brand of cigarettes that was menthol, including capsule.ExposuresMenthol cigarette ban, comparing 3 countries over time: Canada, where a ban already existed, England, where a ban was implemented during the study, and the US, where no national ban was present. Age, sex, race, and consumption and dependence were also examined by menthol smoking in each country, and in England before vs after the ban.ResultsThe analytical sample comprised 7067 participants aged 16 to 19 years, of whom 4129 were female and 5019 were White. In England, the weighted percentage of youth smokers who reported smoking a menthol or capsule cigarette brand was stable in the 3 survey waves before the menthol ban (2018 to February 2020, 9.4% vs 12.1%; adjusted odds ratio [AOR], 1.03; 95% CI, 0.99-1.06; P = .15) but decreased to 3.0% after the ban (February 2020 vs August 2020, AOR, 1.07; 95% CI, 1.04-1.10; P < .001). The decrease between February and August 2020 in England was similar across all demographic groups but was greater among youth who perceived themselves as addicted to cigarettes (AOR, 0.37; 95% CI, 0.41-0.97; P = .04). In the 2 comparison countries, menthol or capsule smoking was stable across all waves (2018 to August 2020: US, 33.6%-36.9%; Canada, 3.1%-2.3%) and was more prevalent in the US than in England (AOR, 5.58; 95% CI, 4.63-6.72; P < .001). Menthol or capsule smoking was also more prevalent among smokers in England who were female vs male (10.9% vs 7.2%; AOR, 1.04; 95% CI, 1.01-1.06; P = .002); among smokers in the US who identified as Black vs White (60.6% vs 31.9%; AOR, 1.33; 95% CI, 1.23-1.44; P < .001) or who were frequent smokers (AOR, 1.07; 95% CI, 1.01-1.13; P = .03), smoked more cigarettes per day (2-5 vs 1, AOR, 1.09; 95% CI, 1.02-1.15; P = .006; >5 vs 1, AOR, 1.10; 95% CI, 1.03-1.18; P = .007), or had urges to smoke every or most days (AOR, 1.08; 95% CI, 1.02-1.14; P = .006); and among smokers in Canada who perceived themselves as addicted to cigarettes (AOR, 1.02; 95% CI, 1.00-1.03; P = .01).Conclusions and relevanceIn this survey study, the proportion of youth smokers who smoke menthol (including capsule) cigarettes decreased substantially after the menthol ban in England. This association was consistent across all demographic groups. Perceived addiction among menthol smokers was also lower where menthol cigarettes were banned.

Project description:IntroductionHeated tobacco products (HTPs), such as IQOS, have been introduced in a growing number of international markets. However, little is known about perceptions of HTP products among youth.MethodsData are from wave 1 of the International Tobacco Control Youth Tobacco and E-cigarette Survey (2017), a web-based cohort survey of people aged 16-19 years from Canada, England and the USA. Respondents (n=12 064) were shown an image of IQOS and asked about their awareness, interest in trying and susceptibility to trying the product. Youth awareness, interest in trying and susceptibility to trying IQOS were analysed using descriptive statistics, and logistic regression models were used to examine correlates of these outcomes.ResultsOverall, 7.0% of youth reported awareness of IQOS (England=5.6%, Canada=6.4% and USA=9.1%) and 38.6% expressed interest in trying the product (England=41.8%, Canada=33.0% and USA=40.9%). Within each country, all key outcomes varied by smoking status: greater proportions of youth who were currently smoking or had a history of smoking reported being aware of, interested in trying and susceptible to trying IQOS. Interest and susceptibility to trying IQOS were associated with male sex, current tobacco use and current e-cigarette use. Across all countries, susceptibility to trying IQOS (25.1%) was higher than for tobacco cigarettes (19.3%), but lower than for e-cigarettes (29.1%).ConclusionsAwareness of HTPs, such as IQOS, is emerging among youth in Canada, England and the USA. Interest in trying these products is very high among smokers, but also present among non-smokers.

Project description:ObjectivesThe last 5 years have seen substantial changes in England's social and economic landscape as a result of Brexit, the COVID-19 pandemic and cost of living crisis. We aimed to examine changes in cross-border and illicit tobacco purchasing over this period.DesignNationally representative monthly cross-sectional survey.SettingEngland, 2019-2022.Participants11 232 adults (≥18 years) who smoked in the past year.Main outcome measuresWe estimated time trends in the proportion reporting purchasing tobacco from (1) cross-border and (2) illicit sources in the past 6 months.ResultsBetween February 2019 and October 2022, there was a non-linear increase in the proportion of participants reporting cross-border tobacco purchases (from 5.2% to 16.1% overall; prevalence ratio (PR)=3.10, 95% CI 2.03-4.73). Prevalence first increased from 5.2% to 15.4% between February 2019 and April 2020, before falling to 7.8% between April 2020 and September 2021 during the COVID-19 pandemic, and then increasing again to 16.1% by the end of the period. Changes in cross-border tobacco purchasing were more pronounced among participants from more advantaged (from 6.6% to 23.3%; PR=3.52, 95% CI 2.05-5.91) compared with less advantaged (4.4% to 11.5%; PR=2.61, 95% CI 1.17-5.20) social grades (pinteraction=0.034). There was no overall change in the proportion reporting illicit tobacco purchases (from 9.2% to 8.5%; PR=0.92, 95% CI 0.70-1.21), nor any significant difference in trends by social grade (pinteraction=0.783).ConclusionsDespite a fall in cross-border tobacco purchasing during the first year of the COVID-19 pandemic among adults in England who smoke, the proportion reporting cross-border tobacco purchases is now three times higher than it was at the start of 2019. The proportion reporting illicit tobacco purchases has not changed substantially.
