Background: Preventing 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.
Methods: Repeat 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.
Results: The 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.
Conclusions: Patterns 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.
