Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Elly Leavens, University of Kansas Medical Center, USA. Associate Professor Jamie Hartmann-Boyce and Associate Professor Nicola Lindson discuss the new evidence in e-cigarette research and interview Dr. Elly Leavens, Assistant Professor in the Department of Population Health at the University of Kansas Medical Center.
In the November 2025 podcast Elly Leavens talks about her recent pilot trial published in Frontiers in Public Health, called 'E-cigarette puff topography instruction to enhance switching among COPD patients who smoke'. This pilot study was supported by funds from the Cancer Prevention and Control Program within the University of Kansas Cancer Center, as well as by the National Cancer Institute. The 46 participants who smoked and had chronic obstructive pulmonary disease (COPD) completed a 12-week e-cigarette switching trial in which they were randomized to brief advice or low intensity, or high-intensity puffing topography training. Elly Leavens and colleagues found that e-cigarettes had potential to minimize harm in COPD patients who smoke, but that, puff topography training did not change switch success or reduction in cigarette smoking as compared to the brief advice to switch.

Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research interview Jaqueline Avila. Associate Professor Jamie Hartmann-Boyce and Associate Professor Nicola Lindson discuss the new evidence in e-cigarette research and interview Professor Jaqueline Avila from the Department of Gerontology, University of Massachusetts Boston, USA. Professor Avila describes their pilot study to assesses the harm-reduction potential of e-cigarettes and oral nicotine pouches among people who smoke with low socioeconomic status. This pilot of 45 people provides novel evidence that e-cigarettes and nicotine pouches can be a harm-reduction tool for individuals with lower SES who smoke and are not willing to quit smoking, contributing to reducing tobacco-related disparities in this population. This study is funded by Brown University.
