- 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.
- 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.
- 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.
- 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.
- 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.

Consumers
- Approximately half of the respondents believed they [HTPs] are safer than traditional cigarettes and almost 1/4 believed they are safer than e-cigarettes.
- Among the respondents, 57.9% declared, that e-cigarette use causes serious diseases, with significant differences between smokers and non-smokers (60.4% vs. 49.1%, p = 0.01). Over a quarter of respondents (27.9%) did not know whether e-cigarette use causes disease. Lung cancer was the most common (65.8%) health effect of e-cigarette use indicated by the respondents. More than half of respondents believed that e-cigarette use causes stroke (54.4%) or myocardial infarction (59.4%), wherein non-smokers compared to smokers (p < 0.001) more often declared that e-cigarette use causes cardiovascular diseases.
- Among the respondents, 70% declared that e-cigarettes are as harmful as traditional cigarettes, wherein smokers compared to non-smokers more often declared that e-cigarettes are less harmful than traditional cigarettes (28.6% vs. 19.5%; p = 0.01). There were no statistically significant differences (p > 0.05) between smokers and non-smokers in the perception of the harmfulness of heated tobacco products. One-fourth of the respondents declared that smokeless tobacco is less harmful than traditional cigarettes with significant differences between smokers (32.3%) and non-smokers (22.9%; p = 0.01).
- The linear regression analysis indicated that relative to women, men consider slim cigarettes, smokeless tobacco and e-cigarettes to be more harmful than traditional cigarettes (p < 0.05).
- The smokers of traditional cigarettes reported menthol cigarettes to be less harmful than traditional cigarettes, relative to the non-smokers (p = 0.05).
- The smokers of traditional cigarettes reported more harmfulness (compared to traditional cigarettes) in menthol, slim cigarettes, and e-cigarettes comparing to the non-smokers (p ≤ 0.03).

- Between 2014 and 2019 in England, at the population level, monthly changes in the prevalence of accurate harm perceptions among current tobacco smokers were strongly associated with changes in e-cigarette use.
- For every 1% decrease in the mean prevalence of current tobacco smokers who endorsed the belief that e-cigarettes are less harmful than combustible cigarettes, the mean prevalence of e-cigarette use decreased by 0.48%

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.
- 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.

- 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.
- 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.
- 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.
- 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.
- Between 2017 and 2018, the percentage of US adults who perceived ENDS to be less harmful than cigarettes decreased, while there was an increase in the proportion of US adults who perceived ENDS to be more harmful or much more harmful.
- Recent population-level data highlight that 49%–80% of US adults incorrectly believe that nicotine is responsible for most of the cancer caused by smoking.
- Additionally, between 23% and 43% of young adults responded “don’t know” to items on nicotine perceptions and more than 50% of respondents, including past 30-day tobacco users, perceived nicotine gum and patch to be as harmful or more harmful than cigarettes to overall health and specifically, to causing cancer or heart attack.
- 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%).
Health Care
- 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.
- 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.

2007: Nurses' knowledge about the risk of light cigarettes and other tobacco "harm reduction" strategies
- Nurses had misperceptions about nicotine replacement: 60% believed that nicotine causes cancer, 72% believed that nicotine patches could cause heart attacks, and 40% and 15% believed that a prescription is needed for the nicotine patch or gum, respectively.
- Nurse misinformation could lead to inaccurate recommendations and failure to capitalize on the teachable moment provided by the medical encounter.
