2022: Do smokers' perceptions of the harmfulness of nicotine replacement therapy and nicotine vaping products as compared to cigarettes influence their use as an aid for smoking cessation? Findings from the ITC Four Country Smoking and Vaping Surveys

• We analyzed data from 1,315 current daily smokers (10+ cigarettes per day) who were recruited at Wave 1 (2016), and who reported making a quit attempt by Wave 2 (2018) of the International Tobacco Control Four Country Smoking and Vaping Surveys in Australia, Canada, England, and the United States.
• Consistent with past studies,our findings confirm that harm perceptions influence nicotine product use, with accurate perceptions associated with greater likelihood of use as a smoking cessation aid, whereas inaccurate perceptions appear to deter their use for this purpose.

2022: Exposure to Negative News Stories About Vaping, and Harm Perceptions of Vaping, Among Youth in England, Canada, and the United States Before and After the Outbreak of E-cigarette or Vaping-Associated Lung Injury (‘EVALI’)

• Between 2017 and February–March 2020, youth exposure to negative news stories, and perceptions of vaping harms, increased, and increases were exacerbated during and immediately after ‘EVALI’. By August 2020, exposure to negative news stories returned to 2019 levels, while perceptions of harm were sustained.

2021: Effects of brief exposure to misinformation about e-cigarette harms on twitter: a randomised controlled experiment

• This is the first study to explore the effect of exposure to misinformation about e-cigarette harms on Twitter, showing that after brief exposure to tweets that e-cigarettes are as or more harmful than smoking, current smokers may be deterred from using e-cigarettes (measured with intention to purchase e-cigarettes) as a harm reduction strategy. They are also more likely to wrongly believe that e-cigarettes are more harmful than regular cigarettes.
• The increasing trends of misperceptions about the relative harms of e-cigarettes compared with regular cigarettes are important for public health because perceived harms of e-cigarettes are associated with smokers' willingness to use e-cigarettes6 as a harm reduction strategy.

2020: Tobacco harm reduction in the 21st century

• These products have been subjected to regulatory bans and heavy taxation and are rejected by smokers and society based on misperceptions about nicotine, sensational media headlines
• These barriers will need to be addressed if tobacco harm reduction is to make the maximum impact on the tobacco endemic.

2020: Inequalities, harm reduction and non-combustible nicotine products: a meta-ethnography of qualitative evidence

• The review only identified studies exploring the attitudes of socioeconomically disadvantaged smokers towards NCNP (non-combustible nicotine products) for harm reduction or cessation purposes (i.e. we did not identify any relevant studies of more advantaged socioeconomic groups).
• Using a lines-of-argument meta-ethnographic approach, we identified a predominantly pessimistic attitude to NCNP for harm reduction or cessation of smoking due to:
  • wider circumstances of socioeconomic disadvantage;
  • lack of a perceived advantage of alternative products over smoking;
  • and a perceived lack of information about relative harms of NCNP compared to smoking.

2022: What are people’s views about the risks of vaping? Findings from conversations with the public.

• The graph (see website) shows that since 2013 there has been an increase in people inaccurately thinking that vaping is equally or more harmful than smoking among adults in Great Britain.
• People were asked what they thought was causing this increase in inaccurate beliefs:
  • ‘Youth vaping epidemic’ (the increase in youth vaping, particularly seen in the US) and increasing perceptions that vaping is for younger people
  • Misinformation about vaping (for example, that it can cause popcorn lung)
  • Negative news stories about vaping
  • Increasing disapproval of vaping
  • Vaping becoming the ‘new smoking’ (smoking becoming less prevalent while vaping becomes more prevalent, so there’s less to compare vaping to / less of a ‘negative comparison’)
  • Increasing discussions and education in school about ‘negative consequences of vaping’
  • Desensitisation to public health messaging about the reduced harm of vaping relative to smoking

2022: Myths and Misinformation: Mapping the barriers to smoking cessation and the uptake of nicotine alternatives

• ...with 93% of Brits overestimating the health risk of nicotine,...The over 60s and those from the lowest socio economic groups (C2DE) are the most likely to be misinformed...

2022: The Khan review Making smoking obsolete

• However, there is lots of confusion, even misinformation, about vaping. The most common relates to its harm. I have spoken to the very best academics and scientists across the country and internationally. They all told me that vaping is far less harmful than smoking.
• In cigarettes, we know that it is not the nicotine that kills you but the other thousands of toxic chemicals such as tar and carbon monoxide. Vapes give smokers the nicotine they crave but protect them from the toxins they would inhale from a cigarette.

2022: Associations Between Nicotine Knowledge and Smoking Cessation Behaviors Among US Adults Who Smoke

• This study provides longitudinal evidence that among adult smokers, misperceiving nicotine as a primary cause of smoking-related diseases may be associated with reduced cessation success and lower likelihood of using less harmful nicotine products. These misperceptions may therefore impede efforts to encourage smokers ready to quit to use evidence-based cessation support such as nicotine replacement during quit attempts and limit the success of policies designed to shift smokers to less harmful sources of nicotine.

• Their well-intentioned but misguided and unscientific beliefs, however, may actually reap a consequence they certainly do not intend: increased youth cigarette smoking.
• Yet many government regulators and elected officials have allowed misinformed and misguided activists who refuse to discuss the science behind tobacco harm reduction to take the reins on this vital public health issue, while in other countries (Great Britain and New Zealand, for example), governments leverage tobacco harm reduction strategies to save lives.

2020: Perception of the relative harm of electronic cigarettes compared to cigarettes amongst US adults from 2013 to 2016: analysis of the Population Assessment of Tobacco and Health (PATH) study data

• In this study, the proportion of US adults who incorrectly perceived e-cigarettes as equal to, or more, harmful than cigarettes increased steadily regardless of smoking or vaping status.
• Current adult smokers appear to be poorly informed about the relative risks of e-cigarettes yet have potentially the most to gain from transitioning to these products.
• The findings of this study emphasise the urgent need to accurately communicate the reduced relative risk of e-cigarettes compared to continued cigarette smoking and clearly differentiate absolute and relative harms.
