Abstract

Aims: To measure changes over time (between 2017 and 2023) in disposable e-cigarette use and popular brands among youth in Canada, England and the United States (US) who vaped.

Design: Nine waves of repeat cross-sectional data from the International Tobacco Control Policy Evaluation Project (ITC) Youth Tobacco and Vaping Survey.

Setting: Online surveys conducted in Canada, England and the US between 2017 and 2023.

Participants: Youth aged 16 to 19 years who had vaped in the past 30 days (n = 19 710).

Measurements: Usual type (disposable, cartridge/pod, tank) and brand of e-cigarette used; covariates sex at birth, age, race/ethnicity, cigarette smoking status, vaping on ≥20 of the past 30 days.

Findings: In 2017, the majority of youth who vaped in the past 30 days reported using refillable tank e-cigarettes, whereas disposable e-cigarettes were the least commonly used product type in Canada (10.0%), England (8.6%) and the US (14.4%). Cartridge/pods overtook tank devices in Canada and the US by 2020; however, by 2023, disposables were the leading type of e-cigarette used by youth who vaped in all three countries (Canada = 58.5%; England = 83.2%; US = 67.3%). The shift to disposables occurred among all socio-demographic groups, with few differences by vaping and smoking status. The percentage of youth who vaped that reported ‘no usual’ brand also decreased substantially from 2017 (29% to 42%) to 2023 (11% to 17%). The rise of disposable e-cigarettes appeared to be driven primarily by individual brands in the US (Puff Bar in 2020/2021, Elf Bar in 2022/2023) and England (Elf Bar in 2022/2023).

Conclusions: The e-cigarette market has evolved rapidly with notable shifts in the types of e-cigarettes used by youth who vape in Canada, England and the United States. Although the timing differed across countries, major shifts in device types appear to be driven by individual brands and were often accompanied by increases in vaping prevalence among youth.
