Let's talk e-cigarettes, February 2026

What this episode covers

Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Jodi Gilman, Department of Psychiatry at Harvard Medical School and Massachusetts General Hospital. Associate Professor Jamie Hartmann-Boyce and Associate Professor Nicola Lindson discuss the new evidence in e-cigarette research and interview Dr Jodi Gilman, Associate Professor of Psychology in the Department of Psychiatry at Harvard Medical School and Massachusetts General Hospital. In the February 2026 podcast Jodi Gilman talks about their secondary analysis of a randomised clinical trial looking at cannabis use and nicotine vaping cessation outcomes among adolescents and young adults. Participants were 16 to 25 and reported vaping nicotine regularly and did not smoke tobacco. The full study assessed the efficacy of varenicline for nicotine vaping cessation. For more detail on the parent trial listen to the interview with Eden Evins in the April 2025 podcast. Jodi Gilman discusses the finding that, among adolescents and young adults attempting to reduce or stop nicotine vaping, baseline cannabis use was not associated with nicotine vaping abstinence. Varenicline was helpful for nicotine vaping cessation regardless of cannabis use. This finding indicates that co-use of cannabis may not be a barrier to successful nicotine vaping cessation treatment. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and Interventions for quitting vaping review and shares the evidence from the monthly searches.
