ABSTRACT
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.
ABSTRACT
INTRODUCTION: The UK has achieved reductions in illicit tobacco (IT) market size and share. However, there remains a 17.7% tobacco duty gap, contributing to health inequalities. In January 2024, the UK government announced a new strategy to control IT, along with provision of new funding. METHODS: A representative cross-sectional survey of adults in England ran in April 2022 to evaluate attitudes and exposure to IT. Tobacco smokers were asked questions about encounters with IT, while all participants answered questions on knowledge and perspectives on IT. RESULTS: Of 262 tobacco smokers, 18.3% (95% CI 13.8% - 23.6%) had come across IT in the past year. Men had four times the odds of encountering IT recently than women. Among 1,767 adults responding to questions on IT, two-thirds agreed IT harmed children, and more than half agreed IT was linked to organised crime. Younger adults, smokers and those in lower socio-economic groups were less likely to agree IT was harmful. CONCLUSIONS: Exposure to IT, especially among younger males, remains a concern. While most of the public acknowledge its harm, this is not universal, and some population groups are less likely to do so. IMPLICATIONS: The study highlights persistent exposure to illicit tobacco in England, especially among younger males, and varying perceptions of illicit tobacco harm across socio-economic groups. Tackling illicit tobacco requires collaboration between health and enforcement agencies, independent of the tobacco industry's influence. Strategies should include components that shift demand for illicit tobacco and denormalise its presence in communities, particularly in lower socio-economic areas with higher smoking prevalence.
