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: Video: Depression causes vaping!

• In this talk Professor Notley will discuss the latest evidence exploring associations between nicotine use and common mental health conditions, including depression.
• Interpretive assumptions will be drawn out, including inappropriate claims of causal relationships between vaping and depression.

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: 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.

• About 61.2% of smokers believe nicotine causes cancer or don't know.
• High perceived threat of tobacco may be overgeneralized to nicotine. High prevalence of the misperception among Non-Hispanic Black and low-income smokers is concerning, considering existing health disparities. Messaging should attempt to correct the misperception that nicotine causes cancer.

• 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.

2019: Perceived Comparative Harm of Cigarettes and Electronic Nicotine Delivery Systems

• Public education is an essential complement to the Food and Drug Administration’s efforts to move smokers away from combusted tobacco products and prevent non-users from trying nicotine and tobacco products.
• Following exposure, nicotine education participants reported fewer false beliefs about nicotine, nicotine replacement therapies, e-cigarettes, and reduced nicotine cigarettes compared with the control conditions.
• Nicotine messaging doubled the probability of a correct response (false, 78.3% vs 36.8%) to nicotine is a cause of cancer and dramatically reduced the probability of responding don’t know to this item (5.3% vs 26.0%).

2021: Persistent Misperceptions about Nicotine among US Physicians: Results from a Randomized Survey Experiment

• Question wording is important when measuring physicians’ beliefs about nicotine; however, even after accounting for question version, misperceptions about the direct health effects of nicotine were common and varied by sex and specialty.

2020: Nicotine Risk Misperception Among US Physicians

• Overall, the majority of physicians “strongly agreed” that nicotine directly contributes to the development of cardiovascular disease (83.2%), COPD (80.9%), and cancer (80.5%). Comparatively fewer “strongly agreed” that nicotine directly contributes to the development of birth defects (32.9%) and 30.2% did not answer this question—a potential indicator of “do not know.”
• While it is possible that some physicians may have misunderstood the question (e.g., considered harm caused by tobacco, rather than nicotine), results are consistent with other studies finding notable nicotine misperceptions.
