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. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. Our literature searches carried out on 1st April found: Avila JC, Maglalang DD, Nollen N, Lee SC, Suh R, Malone M, Binjrajka U, Ahluwalia JS, Using pod based e-cigarettes and nicotine pouches to reduce harm for adults with low socioeconomic status who smoke: a pilot randomized controlled trial Nicotine & tobacco research 2024. 10.1093/ntr/ntae047.

Mon, 29 Apr 2024 - 31 - March 2024 Ian Pope
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research interview Ian Pope. Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the new evidence in e-cigarette research and interview Dr Ian Pope, an emergency medicine physician and honorary associate professor at Norwich Medical School, about his new trial, which he co leads with Professor Caitlin Notley from the University of East Anglia. The new trial is the COSTED trial, the Cessation of Smoking Trial in the Emergency Department and funded by the British National Institutes of Health Research. This is a multi-centre randomised controlled trial, based in 6 emergency departments around the UK. This study tested the real-world effectiveness of an emergency department based smoking cessation intervention that included provision of an e-cigarette starter kit compared to usual care. (ClinicalTrial.gov:NCT04854616). Adults who smoke tobacco and were attending one of six EDs across the UK were randomised to either control (in which case they were given written information about stop smoking services) or intervention (brief smoking cessation intervention, provision of an e-cigarette starter kit, and referral to stop smoking services). Both groups were followed up 1, 3 and 6 months after randomisation. Smoking abstinence was biochemically verified at 6 months. There were over a thousand participants and biochemically verified smoking cessation rate of 7.2% in the intervention group 4.1% in the control group. The study found that it was feasible to implement a smoking cessation intervention in EDs with dedicated staff time to deliver the intervention and that EDs may represent an excellent opportunity to engage hard to reach smokers.

Reto Auer is Head of the Substance Use Unit, where he leads a variety of research projects, including a large randomized controlled trial designed to test the efficacy, safety and toxicology of nicotine e-cigarettes. Jamie Hartmann-Boyce interviews Reto Auer about his new study published in the New England Journal of Medicine ‘Electronic nicotine delivery systems for smoking cessation’. This trial randomized 1246 participants: 622 to free e-cigarettes and e-liquids, standard-of-care smoking-cessation counselling, and optional (not free) nicotine-replacement therapy; and 624 participants to a control group, which received standard counselling and a voucher, which they could use for any purpose, including nicotine-replacement therapy. This study was funded by the Swiss National Science Foundation and others and registered as ESTxENDS NCT03589989. The percentage of participants with validated continuous abstinence from tobacco smoking was 28.9% in the intervention group and 16.3% in the control group (relative risk, 1.77; 95% confidence interval, 1.43 to 2.20). The study concluded that adding e-cigarettes to standard smoking-cessation counselling resulted in greater abstinence from tobacco use among smokers than smoking-cessation counselling alone.

Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the new evidence in e-cigarette research and interview Assistant Professor Cara Murphy, clinical psychologist at Brown University. Cara Murphy works at the Center for Alcohol and Addiction in the School of Public Health and the Center for Addiction and Disease Risk Exacerbation. Jamie Hartmann-Boyce interviews Cara Murphy about her new trial, Trial for Harm Reduction With Incentives & Vaping E-cigarettes (THRIVE) and funded by the National Institute of General Medical Sciences. This trial will assess the effect of e-cigarettes and incentives on combustible cigarette smoking in individuals with overweight/obesity who smoke cigarettes. A randomized group of participants will given e-cigarettes for 6 weeks. carbon monoxide will be monitored and participants will either receive fixed incentives for sample completion or receive varying incentives contingent on their carbon monoxide levels. Researchers will compare groups to understand the effect of each condition on smoking-related behaviour. Cara outlines how individuals with overweight/obesity who smoke cigarettes have greatly increased risks of metabolic, cardiac, and pulmonary diseases due to the synergistic effects of tobacco and obesity. Cara also discusses issues faced by people who smoke and are overweight. Switching to e-cigarettes may decrease the risk of negative health outcomes and be a promising approach.

Wed, 31 Jan 2024 - 28 - E-cigarette marketing and the effects on young people and adults, with Eve Taylor
Jamie Hartmann-Boyce and Nicola Lindson discuss cigarette packaging, flavours and brand names with Eve Taylor, King's College London. Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the new evidence in e-cigarette research and interview Eve Taylor who is working on a PhD in the Nicotine Research Group at King's College London. Eve also works as a research assistant on projects including the International Tobacco Control Project and the Public Health England e-cigarette evidence reviews. Jamie Hartmann-Boyce interviews Eve Taylor at the E-Cigarette Summit, 16th November at the Royal College of Physicians, London. Eve discusses packaging regulations and the role that cigarette packaging and e-cigarette packaging have on the appeal to young people and adults. She draws on findings from the International Tobacco Control Policy Evaluation Project and Action on Smoking and Health (ASH) survey data. The survey data from ASH shows that young people are less interested in trying e-cigarettes in standardised packaging and colours compared to branded packaging. However, changing the packaging does not affect adults, including adults that use combustible cigarettes. Eve discusses the role of flavour names and brand names. The interview highlights that the consequences of any changes in policy need to be thought through and any changes in regulations need to be clear and easily enforceable.

Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and Ailsa Butler interviews Andrea Leinberger-Jabari from the Public Health Research Center at New York University, Abu Dhabi, United Arab Emirates. Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the new evidence in e-cigarette research. Ailsa Butler interviews Andrea Leinberger-Jabari, Assistant Director for tobacco research at the Public Health Research Center at New York University, Abu Dhabi, United Arab Emirates. Andrea Leinberger-Jabari talks to Ailsa Butler at the Society for Nicotine and Tobacco Research- E annual conference held in London where Andrea was presenting a poster of her work. Andrea describes her study of e-cigarettes and heated tobacco products in people in the United Arab Emirates (UAE). This is part of a larger cohort study at the Public Health Research Center called the UAE Healthy Futures study. Data is collected from Emirati adults residing in the UAE on tobacco use behaviors and, since becoming legal in 2019, on e-cigarettes and heated tobacco. The overall smoking rate is around 30% and men tend to smoke more than women. Of those who smoke combustible tobacco, over half smoke more than one type of combustible tobacco including cigarettes, shisha, pipe tobacco and Doha tobacco. Most e-cigarette users are people who already smoke combustible tobacco, are male, younger and college educated. The views on the perceived harm of e-cigarettes are mixed; people were unsure if they were more or less harmful than combustible tobacco. The top reasons for using e-cigarettes among people who use combustible tobacco, are that they might help them quit, that they are more acceptable than combustible cigarettes and they can be used in places where combustible cigarettes are banned. People not using combustible cigarettes use e-cigarettes out of curiosity and because they taste good. The EC market is new in the UAE and is growing rapidly, so continued monitoring of e-cigarettes and heated tobacco use in this emerging market will inform further policy and regulation The results of this study presented as a poster will be published soon. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. Our literature searches carried out August 1st and September 1st 2023 identified one new (Rose 2023 https://dx.doi.org/10.1007/s00213-023-06401-y), two linked (Przulj 2023 https://doi.org/10.3310/AGTH6901) (Kanobe 2023, https://dx.doi.org/10.3390/toxics11070564) and one new ongoing study (https://clinicaltrials.gov/ct2/show/NCT05960305).

Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Associate Sarah Pratt, Department of Psychiatry, Geisel School of Medicine, Dartmouth University, New Hampshire, USA. Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the new evidence in e-cigarette research and interview Associate Professor Sarah Pratt from Dartmouth University. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. Sarah Pratt discusses her research and her study of e-cigarette provision to people with serious mental illness to support them transitioning away from combustible tobacco. This research is funded by the US National Institute on Drug Abuse. An abstract of this work was presented at the Society for Research into Nicotine and Tobacco, SRNT, meeting in 2023 and published in Nicotine & Tobacco Research last year. People with serious mental illness (SMI) have great difficulty quitting and sustaining abstinence, warranting novel harm reduction strategies, including switching to potentially reduced-harm nicotine products, such as e-cigarettes. Sarah Pratt and her team conducted the first-ever trial of e-cigarette provision with instructions on their safe use versus usual care in 240 chronic smokers with SMI. They tested whether substitution of e-cigarettes could reduce harm as measured by the cigarette metabolite and carcinogen NNAL (the nitrosamine (4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol). The e-cigarette group had significantly lower NNAL at 4 weeks but the group difference was attenuated at 8 weeks. This study demonstrated rapid short-term harm reduction among chronic smokers with SMI assigned to receive e-cigarettes. The attenuation of this effect at 8 weeks suggests that smokers with SMI require more than e-cigarette provision alone to maintain reduced smoking. Sarah and her team conclude that development of a behavioural intervention in addition to e-cigarette provision seems warranted to prevent morbidity and early mortality in this high-risk group of smokers.

Mon, 17 Jul 2023 - 23 - May 2023 Matthew Carpenter
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Matthew Carpenter, Medical University of South Carolina, USA. Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Matthew Carpenter. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In the May 2023 episode Jamie Hartmann-Boyce talks with Professor Matthew Carpenter from the Medical University of South Carolina (MUSC) in Charleston SC, and co-leader of the Cancer Control Program within MUSC Hollings Cancer Center. Matthew Carpenter's primary research interests relate to tobacco use: craving and nicotine dependence, clinical trials for smoking cessation, and public health policy for effective tobacco control. Jamie interviews Matthew at the US E-cigarette Summit in Washington DC and asks about his Naturalistic E-Cig Trial (CONNECT) funded by National Cancer Institute. In this randomised controlled trial 638 participants who use combustible cigarettes are allocated to either: a control arm where they can continue using combustible cigarettes; or given an NJOY electronic cigarette to sample and can continue smoking their usual cigarettes as much or as little as they would like. The study gathered information on e-cigarette product use, purchasing of e-cigarettes and cessation of use of combustible cigarettes at 6 months. The study found an increase in quit attempts and an increase in smoking cessation of combustible cigarettes in the intervention arm.

Wed, 24 May 2023 - 22 - January 2023 Podcast
In this episode Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the emerging evidence in e-cigarette research and interview Professor Jonathan, Penn State College of Medicine. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In the January 2023 episode Jamie Hartmann-Boyce interviews Professor Jonathan Foulds from the Center for Research on Tobacco & Health, Penn State College of Medicine. Professor Foulds discusses his randomised controlled study of the effect of electronic nicotine delivery systems (ENDS) or e-cigarettes on combustible cigarette abstinence in people who use combustible cigarettes with no plans to quit. Their study had 520 adult participants who were interested in reducing but had no plans to quit using combustible cigarettes. The participants received brief advice and were randomized to one of four 24-week conditions, receiving either an eGo-style ENDS paired with 0, 8, or 36 mg/ml nicotine liquid (double-blind) or a cigarette-shaped tube, as a cigarette substitute (CS). Self-reported daily cigarette consumption and exhaled carbon monoxide (CO) were measured at all study visits. At 24 weeks, significantly more participants in the 36 mg/ml condition (10.8%) than in the 0 mg/ml condition (0.8%) and the CS condition (3.1%) were abstinent. The abstinence rate in the 8 mg/ml condition was 4.6%. Their randomized trial found study that few participants quit combustible cigarettes in the short term. However, if participants continued to use an ENDS with cigarette-like nicotine delivery, a greater proportion of participants completely switched to ENDS, as compared with placebo or a cigarette substitute. Jamie and Nicola also bring us up to date with the literature search conducted in January 2023. The searches identified 1 new ongoing study NCT05639790. We will include the studies we have found in future updates of the Cochrane review.

Thu, 26 Jan 2023 - 21 - November 2022 Podcast
In this episode Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the emerging evidence in e-cigarette research and summarise the findings of the newly published update to the Cochrane review of e-cigarettes for smoking cessation. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In the November 2022 episode Jamie Hartmann-Boyce and Nicola Lindson bring us up to date with the latest findings from our Cochrane review of e-cigarettes for smoking cessation. The latest Cochrane Review finds high certainty evidence that nicotine e-cigarettes are more effective than traditional nicotine-replacement therapy (NRT) in helping people quit smoking. Jamie and Nicola summarise their research led by the University of Oxford, and funded by Cancer Research UK, which has found the strongest evidence yet that e-cigarettes, also known as 'vapes', help people to quit smoking better than traditional nicotine replacement therapies, such as patches and chewing gums. The new evidence published in the Cochrane Library finds high certainty evidence that people are more likely to stop smoking for at least six months using nicotine e-cigarettes, or 'vapes', than using nicotine replacement therapies, such as patches and gums. Evidence also suggested that nicotine e-cigarettes led to higher quit rates than e-cigarettes without nicotine, or no stop smoking intervention, but less data contributed to these analyses. The updated Cochrane review includes 78 studies in over 22,000 participants - an addition of 22 studies since the last update in 2021. Smoking is a significant global health problem. According to the World Health Organisation (WHO), in 2020, 22.3% of the global population used tobacco, despite it killing up to half of its users. Stopping smoking reduces the risk of lung cancer, heart attacks and many other diseases. Though most people who smoke want to quit, many find it difficult to do so permanently. Nicotine patches and gum are safe, effective and widely used methods to help individuals quit. E-cigarettes heat liquids with nicotine and flavourings, allowing users to 'vape' nicotine instead of smoking. Data from the review showed that if six in 100 people quit by using nicotine replacement therapy, eight to twelve would quit by using electronic cigarettes containing nicotine. This means an additional two to six people in 100 could potentially quit smoking with nicotine containing electronic cigarettes.

Thu, 24 Nov 2022 - 20 - October 2022 with Dr Leonie Brose
Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the emerging evidence in e-cigarette research and interview Dr Leonie Brose, King's College London. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In the October episode Jamie Hartmann-Boyce interviews Dr Leonie Brose, Reader in Addiction Education and Nicotine Research at King's College London. Leonie Brose talks about the findings of a randomised controlled trial carried out with Dr Markos Klonizakis and the team at Sheffield Hallam University on the medium- and longer-term cardiovascular effects of e-cigarettes in adults making a stop-smoking attempt. The study compared cardiovascular effects in smokers attempting to quit smoking using e-cigarettes with or without nicotine or prescription nicotine replacement therapy (NRT). The study concluded that smokers attempting to quit experienced positive cardiovascular impact after both a 3- and 6-month period. None of the groups (i.e., nicotine-containing and nicotine-free e-cigarettes or NRT) offered superior cardiovascular benefits to the others. https://doi.org/10.1186/s12916-022-02451-9 Dr Brose also discusses the findings of the report by the Office for Health Improvements and Disparities (OHID) on Nicotine vaping in England: 2022 evidence update summary. The report aims to summarise the evidence on vaping products and to inform policies and regulations. It is a large body of work with 16 chapters covering policy and regulation, vaping and youth and presents the evidence on biomarkers of exposure and biomarkers associated with cancer, respiratory, cardiovascular and other health outcomes. The report also has chapters on fires, poisons and explosions linked to ECs, heated tobacco products and perceptions of harm. The headline from the report was that vaping poses only a small fraction of the risk of smoking combustible cigarettes. Jamie and Nicola also bring us up to date with the literature search conducted in October 2022. The October search identified 1 new study (https://doi.org/10.1186/s12916-022-02451-9), 3 ongoing studies and 1 record linked to a previously identified study. We will include the studies we have found in future updates of the Cochrane review.

Thu, 27 Oct 2022 - 19 - September 2022 with Harry Tattan-Birch
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. Jamie and Nicola also bring us up to date with the literature search conducted between July and September 1st 2022. The July, August and September searches found 6 new studies. We will include the studies we have found in future updates of the Cochrane review. For more information on the full Cochrane review updated in September 2021 see: https://doi.org/10.1002/14651858.CD010216.pub6 or our webpage: https://www.cebm.ox.ac.uk/research/electronic-cigarettes-for-smoking-cessation-cochrane-living-systematic-review-1
Wed, 28 Sep 2022 - 18 - June 2022 with Dr Francesca Pesola
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Dr Francesca Pesola. In the June episode Jamie Hartmann-Boyce talks with Francesca Pesola from the Wolfson Institute of Population Health Queen Mary University of London. Dr Francesca Pesola talks to Associate Professor Jamie Hartmann-Boyce about the results from the trial comparing e-cigarettes to nicotine patches for smoking cessation in pregnant women. Professor Tim Coleman discussed this study in the May 2021 podcast and the results have now been published in Nature Medicine, Hajek et al 2022 (DOI: 10.1038/s41591-022-01808-0). Dr Pesola outlines the need to identify smoking cessation aids to help women quit during pregnancy. Dr Pesola discusses the results of their randomised control trial of 1,140 participants comparing refillable e-cigarettes with nicotine patches. In this trial pregnant women who smoke were randomized to e-cigarettes or nicotine patches. Dr Pesola reports that the unadjusted analysis of the primary outcome of validated quit rates at the end of pregnancy were not found to be significantly different between the e-cigarette and nicotine patch arms. However, Dr Pesola explains that some people in the study used non-allocated products, for example people in the nicotine patch group were also found to be using e-cigarettes. This meant that if they then quit there was uncertainty as to whether the quitting behaviour was due to the nicotine patches or to the e-cigarettes. The study team had anticipated this behaviour and pre-specified that they would exclude people who were abstinent and who had used non-allocated products. Dr Pesola reports that after doing this e-cigarettes were found to be more effective than patches. The safety profile was similar for both study products, however, low birthweight (
Wed, 29 Jun 2022 - 17 - May 2022 Podcast with Neal Benowitz
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Neal Benowitz. In this episode Associate Professor Jamie Hartmann-Boyce and Dr Nicola Lindson discuss the emerging evidence in e-cigarette research and interview Professor Neal Benowitz. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. Long description In the May episode Jamie Hartmann-Boyce talks with Neal Benowitz, Emeritus Professor at the University of California San Francisco, Professor Benowitz practices medicine, cardiology and clinical pharmacology and has a particular interest in tobacco as a major risk factor for cardiovascular disease. Professor Neal Benowitz talks to Associate Professor Jamie Hartmann-Boyce about the toxicological data from studies of e-cigarettes. He stresses the importance of comparing e-cigarette use to combustible cigarette use, as the exposure to biomarkers that we can measure is much lower in people who vape than in people who use combustible cigarettes. Professor Benowitz points out that many e-cigarette users have been long-term combustible cigarette users so it is difficult to separate out the effects of each. He highlights the need for longitudinal studies among people who have only used e-cigarettes and have not used combustible cigarettes. Professor Benowitz also discusses the need to look at the different types of e-cigarettes, there are many different products and toxicity will vary between the different e-cigarette devices. Jamie and Nicola discuss recent work comparing biomarkers of harm. Exclusive e-cigarette use was associated with lower levels of biomarkers of harm than exclusive use of combustible tobacco, or use of a combination of combustible tobacco. This work was funded by the Oxford University Public Policy Challenge Fund and Cancer Research UK. Jamie and Nicola also bring us up to date with the literature search conducted on May 1st 2022. The May search found 2 new studies, 3 new ongoing studies and 2 records linked to previously identified studies. We will include the studies we have found in future updates of the Cochrane review.

Wed, 01 Jun 2022 - 16 - April 2022 with Assistant Professor Alex Liber
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Alex Liber. In the April episode Jamie Hartmann-Boyce talks with Assistant Professor Alex Liber, Department of Oncology at Georgetown University's School of Medicine, Washington DC, USA. Alex Liber discusses his work at the intersection between markets, public policy, and public health. Alex Liber discusses global tobacco control policy research and tax and price policy. He talks about why different countries react differently to policies and to why tobacco control is seen as the battle of politics, business, and health. He discusses the need for comparative regulatory language. Alex discusses the different e-cigarette policies adopted around the world. Turning to flavours Alex tells us about his work with his colleagues at Georgetown and the University of Michigan on the potential effects of a ban on the sale of menthol cigarettes in the United States. He expanded this work to on menthol cigarettes to look at European sales data and to the effect of the European Union's menthol cigarette ban of menthol cigarette sales in Poland. He reports that although the share of menthol cigarettes sales was 30% in Poland, cigarette sales overall did not drop. He explains that tobacco companies were able to convert their menthol cigarette smokers into standard flavour cigarette smokers, via rebranding cigarettes and flavouring cards. Alex is interested in documenting industry responses. Alex also discusses work looking at e-cigarette flavour bans and temporary bans in the US. Jamie and Nicola also bring us up to date with the literature search conducted on April 1st 2022. The April search found 4 new ongoing studies. We will include the studies we have found in future updates of the Cochrane review.

Tue, 26 Apr 2022 - 15 - March 2022 with Dr Ailsa Butler
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Dr Ailsa Butler. Assistant Professor Jamie Hartmann-Boyce and Dr Nicola Lindson talk with Dr Ailsa Butler from the Centre for Evidence Based Medicine, University of Oxford and co-author of the Cochrane review of e-cigarettes for smoking cessation. They discuss the findings of their recent work on the longer term use of e-cigarettes when provided as a tool to stop smoking. In the studies eligible for the review, just over half of people given nicotine e-cigarettes at study start were found to be still using e-cigarettes at six or more months follow up. Of successful quitters, 70% were found to still be using e-cigarettes at six months or more. The longer-term use of nicotine e-cigarettes may reflect their success as a quit smoking aid by preventing relapse to smoking. A key question about long-term e-cigarette use in people who have quit combustible cigarettes is whether it prevents or facilitates relapse or has no effect on relapse. This work was funded by Cancer Research UK and Oxford University's Public Policy Challenge Grant. Jamie and Nicola also bring us up to date with the literature search conducted on March 1st 2022. The search found 1 record linked to a study already identified as ongoing. We will include the studies we have found in future updates of the Cochrane review.

Fri, 28 Jan 2022 - 12 - November 2021 with guest Professor Anne Joseph
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Professor Anne Joseph. In the November 2021 episode Jamie Hartmann-Boyce talks with Professor Anne Joseph from the Department of Medicine, University of Minnesota Medical School, Minneapolis, about her study carried out with a team at the University of Minnesota and study's first author Kolawole Okuyemi, Department of Family and Preventive Medicine, University of Utah, Salt Lake City. DOI: 10.1093/ntr/ntab212 Professor Anne Joseph discusses her team's recent study that compares the effects of e-cigarettes with and without nicotine on patterns of combustible cigarette use and biomarkers of exposure to tobacco toxicants among African American smokers. Professor Joseph outlines that there are many reasons to look at the question of e-cigarette use with and without nicotine among African American smokers. African Americans are disproportionately impacted by tobacco-related diseases, for example lung cancer. This is in spite of different patterns of smoking by African Americans, such as smoking fewer average cigarettes per day but having more difficulty stopping smoking. In real world settings people change their behaviour without support of researchers and clinicians, Professor Joseph's study aimed to replicate this by providing little behavioural support. Participants were given a choice of menthol and non-menthol flavoured e-cigarette cartridges and were asked to use e-cigarettes ad libitum for 6 weeks. The majority of participants (88.6%) selected menthol e-cigarettes. Follow-up assessments were conducted at 2, 6, and 12 weeks post randomisation. Contrary to their hypotheses, they found that nicotine e-cigarettes did not significantly reduce the use of combustible cigarettes compared to non-nicotine e-cigarettes in this cohort of African American smokers. Their findings suggested that e-cigarettes were modestly associated with decreased use of combustible cigarettes among non-treatment seeking smokers, regardless of nicotine content, but without a reduction in tobacco toxicants. Professor Joseph considered that although e-cigarettes have potential to reduce harm if substituted for combusted cigarettes (or if they promoted cessation) because of lower levels of tobacco toxicants, their study suggested that ad libitum use of e-cigarettes among African American smokers, with or without nicotine, resulted in modest smoking reduction but did not change toxicant exposure in a cohort where smoking cessation or reduction was not the goal. The authors considered that their data suggested that testing future harm reduction interventions using e-cigarettes should include more specific behavioural change coaching, including substituting for or completely stopping combusted cigarettes. For more information on the full Cochrane review updated in September 2021 see: https://doi.org/10.1002/14651858.CD010216.pub6 or our webpage. Jamie and Nicola bring us up to date with the literature search conducted on November 1st. The November search found one new study described in the podcast. The DOI for the new included study (Okuyemi 2021) is 10.1093/ntr/ntab212 . We will include the studies we have found in future updates of the Cochrane review.
Thu, 02 Dec 2021 - 11 - October 2021 with special guest Nicholas DeVito
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and interview Nicholas DeVito. In this episode Jamie Hartmann-Boyce and Nicola Lindson discuss the emerging evidence in e-cigarette research and interview Nicholas DeVito. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In the October 2021 episode Jamie Hartmann-Boyce talks with Nick DeVito from the Evidence Based DataLab at the University of Oxford. They discuss his recent research which looks at e-cigarette manufacturers' compliance with clinical trial reporting expectations focussing on trials by Juul Labs and how they report their data. Nick's study was published in BMJ Tobacco Control (http://dx.doi.org/10.1136/tobaccocontrol-2020-056221). The discussion covered the importance of whether, where and how research findings are reported or published including publication bias and reporting bias, the selective reporting of outcomes. This interview covers the crucial role of trial registration for research transparency. Nick describes the FDA amendment act, in which studies are registered within 21 days with pre-registered outcomes and a primary completion date and that the results are to be put onto clinicaltrials.gov within a year. Clinicians, public health professionals, and the public cannot make informed choices about the benefits or hazards of e-cigarettes if the results of clinical trials are not completely and transparently reported. This interview highlights that transparency is key and the importance of all evidence being made available. For more information on the September Cochrane review see: https://doi.org/10.1002/14651858.CD010216.pub6 or our webpage. Jamie and Nicola also bring us up to date with the literature search conducted on October 1st. The October search found one new included study two reports linked to studies already in the review, and one new ongoing (NCT04854616). The DOI for the new included study (Morris 2021) is https://doi.org/10.1007/s11739-021-02813-w. We will include the studies we've found in future updates of the Cochrane review.
Wed, 27 Oct 2021 - 10 - September 2021 update to the Cochrane living review of electronic cigarettes for smoking cessation
Jamie Hartmann-Boyce and Nicola Lindson discuss the September 2021 update of their Cochrane living review of electronic cigarettes for smoking cessation, their response to a paper by Pisinger et al 2020 and emerging evidence in e-cigarette research. In this episode Jamie Hartmann-Boyce and Nicola Lindson discuss the emerging evidence in e-cigarette research and two recent publications by the group: the September 2021 update to the Cochrane living review of electronic cigarettes for smoking cessation; and a response to a paper by Pisinger et al 2020. This podcast is a companion to our Cochrane living systematic Review and shares the evidence from monthly searches and review findings. Jamie and Nicola discuss the team's response to a paper by Pisinger and Vestbo 2020, and underline that the aim of the Cochrane process is to always focus on the evidence (DOI: 10.1183/13993003.02117-2021 or link). They then outline the findings of the September update to the review which includes five new studies that have been added since the April 2021 version and includes search findings up to 1st May 2021. Overall the review includes 61 studies representing 16,759 participants. The main findings remain the same and some new comparisons have been included. 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 also still exists around nicotine containing e-cigarettes compared to no intervention (e.g. continued smoking). This reflects that the quality of the evidence is considered very low according to Cochrane standards. There is moderate certainty evidence that neither nicotine e-cigarettes nor non-nicotine e-cigarettes result in higher numbers of adverse or serious adverse effects. Turning to new comparisons this update includes a study of a pod device (Russell et al), the findings were consistent with the other included studies that showed that more people quit at 6 months or longer using EC than with NRT. This update also includes a study comparing nicotine salt to free-base nicotine e-cigarettes; no clear differences were found between the two. We also included studies that provided 'dual users' (people who already use EC and tobacco cigarettes) with advice on how to use their EC to quit smoking; in one study there was no usable data in a second larger study (Martinez) there was a marginally better quit rate, however there was no clear evidence of benefit. In response to feedback, for the first time in this update, data is included on the proportion of participants still using e-cigarettes or quitting aids) at six months or longer. Data from two studies comparing nicotine EC with NRT were notably different, with one finding no difference in the proportion of participants still using study product at longest follow-up, and the other finding significantly higher levels of EC use than NRT. There was no evidence for a difference in the proportion of people still using EC at longest follow-up in two studies comparing nicotine EC with non-nicotine EC. For all other studies the majority of participants that had been given nicotine EC at the start of the study were still using EC at 6 months or longer. Jamie and Nicola discuss the different ways that this result could be interpreted. It will be important to collect more information on this outcome. For more information on the September Cochrane review see: https://doi.org/10.1002/14651858.CD010216.pub6 or our webpage. Jamie and Nicola also bring us up to date with the literature search conducted on August 1st and September 1st. The August search found one linked study by Rubenstein et al 2021 (doi: 10.1016/j.addbeh.2021.107037) and two new ongoing studies (El-Khoury et al 2021 (doi: 10.1136/bmjopen-2021-048859); and NCT04708106 2021). No new studies were found in the September 1st search. We will include the studies we've found in future updates of the Cochrane review.
Tue, 21 Sep 2021 - 9 - July 2021 with special guest Dr Katie Myers Smith
Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research. Dr Katie Myers Smith discusses findings from her recent study. Jamie Hartmann-Boyce and Nicola Lindson discuss emerging evidence in e-cigarette research and Dr Katie Myers Smith responds to questions on her recent research. This podcast is a companion to the electronic cigarettes Cochrane living systematic review and shares the evidence from the monthly searches. In the July episode Dr Katie Myers Smith from Queen Mary University of London talks about her team's recent study looking at e-cigarettes versus nicotine replacement therapy (NRT) as a harm reduction intervention for people who smoke and who find quitting difficult. Their randomised controlled study compared e-cigarettes with NRT in 135 people who smoked and who were previously unable to stop smoking with conventional treatments. Dr Myers Smith's study found that in people who smoked and were unable to quit using conventional methods, e-cigarettes were more effective than NRT in facilitating validated long-term smoking reduction and smoking cessation, when limited other support was provided. We will include the results in our Cochrane review. For more information on the study see Myers Smith et al 2021, Addiction, June 2021, DOI: 10.1111/add.15628 . Our July 2021 literature search identified two new included studies (Myers Smith et al 2021, DOI: 10.1111/add.15628 ; Kimber et al 2021 DOI: 10.1016/j.addbeh.2021.106909 ) and two reports linked to studies already in the review (Leavens et al 2021, DOI: 10.1111/add.15597 linked to Pulvers 2020; Jones et al 2021, DOI: 10.1097/ADM.0000000000000881 linked to Klonizakis 2017).

In the June episode Jamie Hartmann-Boyce talks with Professor Thomas Brandon from the University of South Florida and the Moffitt Cancer Center on his team's new study published in Lancet Public Health. This study is a randomised control trial and investigates the effect of tailored advice to dual users of combustible and electronic cigarettes on how to use their electronic cigarette to quit combustible cigarettes. This targeted self-help intervention with high potential for dissemination could be efficacious in promoting smoking cessation among dual users of combustible cigarettes and e-cigarettes. We will include the results in our Cochrane review. For more information on the study see: Martinez 2021 (https://www.thelancet.com/pdfs/journals/lanpub/PIIS2468-2667(20)30307-8.pdf). Our June 1st literature search found one new protocol by Elling et al 2021 (doi: 10.2196/27088) and two linked studies (NCT01188239 linked to Caponnetto 2013a and a dissertation by Guttentag linked to Tseng 2016 (doi: 10.1093/ntr/ntw017).

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.
Wed, 26 May 2021 - 5 - 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

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.
