Smoking remains the leading cause of preventable illness and premature death in the UK. Smoking among children and young people has declined substantially over recent decades, with fewer than 1 in 20 (4.8%) 11 to 17-year-olds in Great Britain currently smoking in 2026. Around 18% report having ever smoked.

However, vaping among children and young people remains a concern. According to the latest ASH Youth Smokefree GB survey, 19% of 11 to 17-year-olds have tried vaping and 6% currently vape, with 2% reporting daily use. Following a rapid increase between 2021 and 2023, youth vaping prevalence has stabilised, with ever-use remaining between 18% and 20% since 2023.

Exposure to vaping products through retail environments, online advertising and social media continues to be associated with increased awareness and experimentation among young people. (Action on Smoking and Health - ASH, 2026)
