In our new paper in The Lancet Public Health, we find that nicotine pouch use is rising in Britain, driven largely by increases among young adults, particularly young men. 🔗 Press release: ucl.ac.uk/news/2025/de... 📄 Paper: thelancet.com/journals/lan...

Among people who use heroin, tobacco smoking and illegal drugs cause a similar number of premature deaths buff.ly/tIC0Fqp @danlewer.bsky.social @tattanbirch.bsky.social @sharoncox.bsky.social

Concerns have been raised that vaping has created a 'new generation of nicotine addicts'. We examined changes in the proportion of US high-school students reporting symptoms of nicotine dependence, in the context of changing patterns of nicotine product use. onlinelibrary.wiley.com/doi/full/10....

We have a new paper out today in Lancet Public Health looking at increases in alcohol-specific deaths in England. www.sciencedirect.com/science/arti...

Will the disposable vape ban help reduce youth vaping? We discuss this in our editorial out today. Our conclusion: 1/3 Great to work alongside Katie East and Eve Taylor on this one! onlinelibrary.wiley.com/doi/10.1111/...
