Vaping research priorities - my top ten

Following up on the guest post by Louise Ross: What are the vaping research priorities? Have your say… I have now had my say and wanted to share my top 10 priorities.

Here is a link to the vaping research priorities survey If you have ideas, please respond by 20 March 2019.

Here are the 10 ideas I have submitted (now updated with a postscript)

Practice

1. What are the barriers [technology, usability, experience, perceptions, commercial etc] to smokers switching to vaping, what can we learn from the experience of people who tried but gave up on vaping?

2. What evidence- and experience-based advice can be given to smokers who want to try to quit smoking by vaping e.g. on choosing products,  getting started (simple or advanced products?), getting over the learning curve, immediate versus gradual smoking cessation, what to do if it doesn’t work etc).  Is it beneficial for cessation and relapse prevention to use multiple products – e.g. an e-cigarette and a synthetic snus like Zyn? What should the advice or support offer from GPs, pharmacists, newsagents, smoking cessation professionals look like?

3. Are there smokers (how many) for whom e-cigarettes are not an adequate substitute for smoking but heated tobacco products are?  How should we characterise the difference between e-cigarettes and heated tobacco products to best inform consumers of risks and opportunities? Should they be more or less treated as the same – and how should smoking cessation professionals deal approach heated products.

Risks and benefits

4. How can we make judgements about long-term risk without waiting for decades of epidemiology – given we would know today that cigarettes are dangerous without waiting for actual cancers to develop, can gain similar insights into the relative safety of vaping?

5. By what methods could we know if there was a gateway effect from vaping to smoking and what does the evidence tell us so far?

6. By what methods could we assess the population health impact of the introduction of vaping and other reduced risk technologies, and what does the evidence tell us so far?

Policy

7. How can we evaluate the impact of e-cigarette policies (e.g. strength limits, advertising bans,  tank or container volume limits, indoor vaping bans, taxes, flavour bans) to check for beneficial impact or harmful unintended consequences?

8. What is the effect of tobacco taxation or other anti-smoking policies on economically, mentally ill or otherwise disadvantaged smokers and how can e-cigarettes relieve harmful economic and other impacts on smokers that arise from tobacco control policies?

9. What scientific work needs to be done to prepare for the next iteration of the EU Tobacco Products Directive and what European collaborations can be formed to support it? (Post-Brexit UK is likely to comply with EU law but will have a limited voice in its development).

Research funding

10. By what mechanism could independent researchers leverage far greater funds (c. $80m per year) by influencing and/or peer-reviewing the pipeline of projects developed by the Foundation for a Smoke-Free World – without taking funds from the Foundation?


Note on proposal 10: scrutinising the Foundation for a Smoke Free World.

The last of these (10) might seem a little puzzling, but it is an attempt to see how $80m year for twelve years can be leveraged in a way that has value and impact. In an exchange of letters with the Foundation about independence and accountability, several of us suggested:

8. External scrutiny. Given its controversial nature, the Foundation should submit itself to an exacting external scrutiny and audit regime, which should be independently funded.
The focus of such an effort would be two-fold:
1) To confirm that the finance and business practices of the Foundation are beyond reproach; and
2) To provide independent critical feedback on the programmatic, scientific investments of the Foundation.
For relatively modest expenditure, a third party could quality-assure or challenge the much larger flow of funds through the Foundation. We recognise that external funding may take time to arrange and is not under the direct control of the Foundation, but it would useful to see proposals for independent scrutiny defined within the Foundation’s governance model.

Letter to Derek Yach, Foundation for a Smoke Free World, 16 November 2017. [link

To which the Foundation replied:

8. External Scrutiny – The Foundation sees value in having external scrutiny from a third party. We would welcome exploring with you the logistics of implementing such an approach. For example, it would help to know: (a) your vision of acceptable funding sources which could support external review; (b) who do you think would be the best party or parties to provide the scrutiny, and; (c) to whom that third party would be accountable?

Reply from Derek Yach, Foundation for a Smoke Free World, 9 January 2018. [link]

I haven’t responded to the Foundation’s questions in its reply because it would not be me doing it and it would require careful design – but I do think it is worth considering as part of a research priorities exercise.

Postscript: the other thing I would find interesting – no, essential – is research into ‘the controversy’.  We need a sociological exploration of the beliefs, moral intuitions, loyalties, political world-views, role models, leadership styles and tribalism that underpin the controversy – and I would include myself as a subject.

    Is it possible to imagine that vaping liquids can be produced with not only nicotine but with other psychoactive elements of tobacco? Indeed, vaping is a frustrating experience for many addicted smokers. Nicotine alone does not explain the smokers’ links to tobacco.

    This was my proposal:

    How are e-cigarette aerosol “particles” (droplets) processed once they are deposited in the respiratory tracts? This is an important issue because there is a lot of misinformation on these “particles”. Anti-vaping pseudo-science attempts to conflate them with solid suspended particles (particulate matter) of air pollution and tobacco smoke, which are harmful. There are strong arguments (from what we know of aerosol physics and chemistry) to estimate that e-cigarette droplets are not harmful. However, as far as I know there is still no research on the pharmacology of their interaction with respiratory and pulmonary tissues once they are deposited in the upper and lower airways and the lungs. Once we have good quality research on this issue, it will be possible to assess in a more solid and robust manner health risks from vaping, either for primary users or for bystanders exposed to environmental exhaled vapor.

    Your research priorities, particularly on health impacts, are so wide in scope that imo the resulting research could be almost useless because insufficiently focused.

    • Fair enough, it’s just a steer rather than a specified research programme. Have you put more specific proposals into the survey? If so, please share in a comment. I’m interested in all ideas on this…
