Let's talk e-cigarettes, March 2025

What this episode covers

Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Monserrat Conde from the University of Oxford. Associate Professor Jamie Hartmann-Boyce and Associate Professor Nicola Lindson discuss the new evidence in e-cigarette research and interview Dr Monserrat Conde from the Nuffield Department of Primary Care Health Sciences, University of Oxford. In the March podcast Monserrat Conde discusses the findings of the recent systematic review of electronic cigarettes and subsequent smoking in young people and an evidence and gap map. The systematic review aims to assess the evidence for a relationship between the use of e-cigarettes /vapes and subsequent smoking in young people under 30, and whether this differs by demographic characteristics. There is very low certainty evidence suggesting that e-cigarette use and availability are inversely associated with smoking in young people (i.e. as e-cigarettes become more available and/or are used more widely, youth smoking rates go down or, conversely, as e-cigarettes are restricted, youth smoking rates go up). At an individual level, people who vape appear to be more likely to go on to smoke than people who do not vape; however, it is unclear if these behaviours are causally linked. Monserrat discusses the differences in the information coming from the population studies compared to the individual level studies and notes that most studies are from high income countries, in particular from the US.
