This paper examined changes in exposure to display of these products in shops and sources of these products among children and adolescent users over timeMethods Data from representative repeated online cross-sectional surveys of youth in Great Britain (11–18 years) were used (2018–2022; n=12 445). Outcome measures included noticing product displays and sources of e-cigarettes and tobacco cigarettes. Logistic regressions examined the associations of these outcome variables over time and with sociodemographic variables.Results Of 12 040 participants with complete data, 10.1% used some form of nicotine product (4.2% cigarettes, 2.9% e-cigarettes, 3.0% both) at least occasionally. The likelihood of noticing tobacco cigarettes on display fell over time for both supermarkets (2018: 67.1% to 2022: 58.5%) and small shops (2018: 81.3% to 2022: 66.3%), but the likelihood of noticing e-cigarettes in supermarkets rose (2018: 57.4% to 2022: 66.5%). Sources of tobacco cigarettes did not differ over time, but e-cigarette users were more likely to get their e-cigarettes from small shops in 2022 (51.2%) vs 2019 (34.2%) (OR 2.02, 95% CI 1.24, 3.29).Conclusion This study provides evidence that current policies to limit awareness of and access to both tobacco and e-cigarettes among adolescents in the UK may not be effective. UK policies on the advertising, promotion and sale of both tobacco and e-cigarettes need to be reinforced to deter use among children and adolescents.Data may be obtained from a third party and are not publicly available.
