Since coming on the market over a decade ago, e-cigarettes have divided opinion. A team of Oxford researchers are searching for new e-cigarette studies every month. In this podcast, Dr Jamie Hartmann-Boyce and Dr Nicola Lindson talk about what has been found, and how this changes what we know about e-cigarettes.
This podcast is made possible through funding from Cancer Research UK.

May 2021 with special guest Professor Tim Coleman
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Tim Coleman. Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Tim Coleman. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches.
In the May episode Jamie Hartmann-Boyce talks with Professor Tim Coleman from the University of Nottingham's Faculty of Medicine and Health Sciences. Professor and GP Tim Coleman discusses a study he is carrying out with colleagues from Queen Mary University of London which looks at helping pregnant women who smoke tobacco cigarettes quit smoking. This trial of 1140 pregnant women compares usual care of behavioural support plus nicotine patches to behavioural support plus e-cigarettes in women willing to receive help to stop smoking. This multi-centre randomised control trial is taking place in the UK and we will include the results in our Cochrane review when these become available. For more information on the study see: https://fundingawards.nihr.ac.uk/award/15/57/85
Our May literature search found four new ongoing studies which may be relevant to our review when they are completed.
April 2021 Cochrane living review of electronic cigarettes for smoking cessation update and questions
Jamie Hartmann-Boyce and Nicola Lindson discuss the April 2021 update to their Cochrane living review of electronic cigarettes for smoking cessation and respond to questions from listeners. Jamie Hartmann-Boyce and Nicola Lindson discuss the April 2021 update to the Cochrane living review of electronic cigarettes for smoking cessation. This podcast is a companion to this Cochrane Review and shares the evidence from monthly searches and review findings.
In this episode Jamie Hartmann-Boyce and Nicola Lindson discuss the latest update to the review and respond to questions covering subjects, such as risk of bias, design of randomised control trials (RCTs), second hand vapour and sustainable cessation, put to them by listeners. This update includes six new studies that have been added since the 2020 version of the review and we are pleased to see the first inclusion of an RCT studying e-cigarette pod devices. There is still moderate certainty that nicotine containing e-cigarettes help more people to quit at 6 months or longer compared to e-cigarettes without nicotine or than NRT (nicotine replacement therapy). Uncertainty still exists around nicotine containing e-cigarettes compared to no intervention (eg continued smoking). This reflects that the quality of the evidence is considered very low according to Cochrane standards. In this update the low certainty evidence for no difference in adverse and serious adverse effects between nicotine e-cigarettes and non-nicotine e-cigarettes has been upgraded to moderate certainty evidence.
Jamie and Nicola also bring us up to date with the literature search conducted on April 1st, which found one linked and two new ongoing studies. doi: 10.3390/ijerph18020430 ; ANZCTR - Registration ; https://doi.org/10.1093/ehjci/ehaa946.2359
March 2021 with special guest Professor Caitlin Notley
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Caitlin Notley. Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Caitlin Notley. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches.
In the March episode Jamie Hartmann-Boyce interviews Professor Caitlin Notley from the Addiction Research Group at the University of East Anglia. The interview covers her qualitative research that centres on electronic cigarettes as a harm reduction tool, smoking cessation and relapse prevention in vulnerable populations. Professor Notley also discusses relapse prevention in pregnant and post-partum women and the role of social identity.
As well as our usual searches, in March we searched conference abstracts from the annual meeting of the Society for Research on Nicotine and Tobacco (SRNT). We identified four new included studies, five new ongoing studies and five papers linked to studies already included in the review. The four new studies identified are summarised in the ‘in a nutshell’ section of the podcast. They are all reported as conference abstracts; three of which were identified from the SRNT 2021 abstract book (SYM2A, SYM2B, PH‐353; https://www.srnt.org/page/2021_Meeting). The fourth was found in a systematic review identified through our search and is available here: http://dx.doi.org/10.1016/j.drugalcdep.2015.07.1091.
February 2021 with special guest Dr Rachna Begh
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Dr Rachna Begh. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In this episode Jamie Hartmann-Boyce and Nicola Lindson interview Dr Rachna Begh about the findings from her ongoing UK Management of Smoking in Primary Care, MaSC, study. This randomised controlled study explores the feasibility, acceptability effectiveness of general practitioner and nurse promotion of e-cigarettes versus standard care for smoking reduction and abstinence in people who smoke and who have smoking-related chronic diseases who are unwilling to stop smoking.
January 2021 with special guest Professor Jasjit Ahluwalia
Jamie & Nicola review 4 new studies & interview Prof Jasjit Ahluwalia. In this episode Jamie Hartmann-Boyce and Nicola Lindson interview Professor Jasjit Ahluwalia about his team’s recent study on the effect of pod e-cigarettes vs cigarettes on carcinogen exposure among African American and Latinx smokers (Pulvers, 2020, see links to all studies in short description above). They also talk through three other studies: Schiebein et al, an exploratory non-randomized study of an e-cigarette intervention with people accessing a homeless supported temporary accommodation service; Orga-Hess et al’s study which tested a method for evaluating the effects of e-cigarettes on quit-related motivation and behaviour; and a study by Yingst et al which explored the acceptability of electronic nicotine delivery systems (ENDS) among HIV positive smokers.
