Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Harry Tattan-Birch. In the September episode Jamie Hartmann-Boyce interviews Harry Tattan-Birch from the Department of Behavioural Science and Health, University College London. Harry Tattan-Birch talks about their team's recent randomised controlled trial examining whether, in adults receiving behavioural support, offering e-cigarettes together with varenicline helps more people stop smoking cigarettes than varenicline alone. Tentative evidence suggests that offering e-cigarettes alongside varenicline to people receiving behavioural support may be more effective for smoking cessation than varenicline alone. https://doi.org/10.1093/ntr/ntac149 Harry Tattan-Birch also discusses his research into heated tobacco products.

This work was funded by the Oxford University Public Policy Challenge Fund and Cancer Research UK.
