RESUMO
BACKGROUND: The popularity of e-cigarettes is on the rise among current cigarette users. Therefore, there are concerns about their health implications. This study examined the impact of health-related social media use on e-cigarette use among current cigarette users. It assesses the mediating influence of online anti-tobacco messages and the moderating role of the harm perception of e-cigarettes. METHODS: This study was focused on 563 current cigarette users from the 2022 Health Information National Trends Survey (HINTS). Three tasks were performed: (1) assessing the direct and indirect impacts of health-related social media use on e-cigarette use among current cigarette users, (2) exploring the mediating role of exposure to online anti-tobacco messages, and (3) examining the moderating influence of e-cigarette harm perception on the path from anti-tobacco messages to e-cigarette use. RESULTS: Health-related social media use was positively associated with current cigarette users' e-cigarette use directly (bp = 0.183, p < .01) and indirectly through exposure to online anti-tobacco messages (bp = 0.023, 95% CI: [0.001, 0.051]). Harm perception of e-cigarettes moderated the relationship between online exposure to anti-tobacco messages and e-cigarette use (bp=-0.467, p < .01). The relationship appeared weaker for individuals who perceived greater harm from e-cigarettes. CONCLUSIONS: Health-related social media use positively correlates with e-cigarette use among current cigarette users through exposure to online anti-tobacco messages. The perceived harm of e-cigarettes moderates this indirect path. These findings have implications for public health interventions aimed at smoking cessation.

BACKGROUND: Current e-cigarette use has increased among young adults in the USA despite a consistent decrease in perceiving e-cigarettes as less harmful than cigarettes over time. This study examined time-varying predictors associated with the changes in e-cigarette relative harm perception over time among US young adults. METHODS: Data were from the 2013-2018 Population Assessment of Tobacco and Health (PATH) Study for young adults (18-24 years). A time-varying effect model (TVEM) was applied to examine the association between the relative harm perception change and the associated time-varying predictors. RESULTS: Of the 8427 young adults, the prevalence of those who perceived e-cigarettes as less harmful than cigarettes decreased from 50.3% in Wave 1 (2013-2014) to 27.7% in Wave 4 (2016-2018). Young adults who were male were more likely to perceive e-cigarettes as less harmful than cigarettes over time (OR = 1.58; 95%CI, 1.53-1.64). In addition, the changes in e-cigarette relative harm perception were less noticeable among those with advanced degrees, who had non-combustible smoke-free home rules, who held negative tobacco-related attitudes, and those who were current e-cigarette users or ever used alcohol (all p values < 0.05). CONCLUSIONS: A decline was observed in US young adults who perceived e-cigarettes as less harmful than cigarettes from the PATH Study across four waves (2013-2018). The study findings underscore the importance of risk communication that focuses on harm perception profiles and the need for appropriate interventions to balance the considerations of e-cigarette use among young adults.

OBJECTIVES: This study investigates the effect of e-cigarette-related harm and addiction perceptions on e-cigarette initiation among US tobacco-naïve adolescents. STUDY DESIGN: This is a longitudinal study. METHODS: Using data from five waves (2013-2019) of the Population Assessment of Tobacco and Health Study, we created a longitudinal data set for 2775 youth aged 12-17 years who had no prior use of tobacco products at Wave 1. E-cigarette initiation was defined as transitioning from non-use at Wave 1 to ever use in subsequent waves. Kaplan-Meier survival and Cox proportional hazard regression models were used to assess the impact of harm and addiction perceptions on e-cigarette initiation. RESULTS: Our analytic sample comprised 63.1% of youth who had never used tobacco products at Wave 1 and consequently initiated e-cigarette use in subsequent waves. Over time, fewer individuals perceived e-cigarettes as harmless (14.1%-2.1%), whereas more perceived them as likely to cause addiction (53.7%-76.6%). Compared with perceiving e-cigarettes as a lot of harm, those perceiving some harm (adjusted hazard ratio [aHR] = 1.30, 95% confidence interval [CI]: 1.12-1.52), little harm (aHR = 1.42, 95% CI: 1.20-1.68), or no harm (aHR = 2.09, 95% CI: 1.64-2.65) were more likely to initiate e-cigarette use. Demographic factors for initiation included being Black or Hispanic ethnicity (vs White), younger age (12-14 vs15-17 years), and receiving over $20 per week (vs $0) in pocket money, with P-values <0.05. However, in adjusted results, addiction perceptions did not significantly impact e-cigarette initiation (P-values >0.05). CONCLUSIONS: Among youth without prior tobacco/nicotine use, perceiving e-cigarettes as having low harm significantly predicted initiation over time. Effective prevention strategies, including targeted risk communication interventions, are essential for discouraging e-cigarette use among youth.

Background: Research is needed to identify the determinants of motivation to quit smoking among non-Hispanic Black (NHB) adults who smoke menthol cigarettes and reside in communities covered by menthol cigarette bans. Objectives: This study examined the associations between motivation to quit smoking and a range of individual-level predictors, including measures of demographics, harm/risk perception of menthol cigarettes, and awareness of a ban on menthol cigarettes in Los Angeles County unincorporated communities. Self-identified NHB adults who currently smoke menthol cigarettes (N=50; M=47.2 years; SD=13.7; 46% female) were recruited in Los Angeles County unincorporated communities. Participants completed an interviewer-administered cross-sectional survey between January to September 2021. Results: Participants (74%) reported an annual household income of less than $25,000. Participants' mean age at cigarette initiation was 15.7 years old (SD=5.68). Most (88%) were aware of the ordinance banning menthol cigarette sales. Employing multivariable linear regression analysis, harm/risk perception of menthol cigarettes (B=14.69, p<0.01) and awareness of the local menthol ban (B=26.18, p<0.05) were found to be independently associated with motivation to quit smoking. Conclusions: Findings from this community-based sample suggest that among NHB adults who smoke menthol cigarettes, motivation to quit smoking is influenced by their perception of menthol cigarettes as harmful and awareness of local policy banning the sale of menthol cigarettes. Findings underscore the need for community-centered and culturally grounded interventions to facilitate quitting among NHB adults who smoke in order for communities covered by menthol bans to achieve health equity in reducing preventable racial inequities due to menthol cigarettes.

Electronic nicotine delivery systems (ENDS) use has dramatically increased in the US. This study aimed to characterize changes in ENDS harm perception over time and associated predictors among US adolescents. Data from the 2013-2018 Population Assessment of Tobacco and Health Study (PATH) for adolescents (12-17 years) were utilized. Trend analyses were employed to delineate changes in comparative and absolute ENDS harm perception over a four-year interval. We applied a time-varying effect model (TVEM) to examine the associations between the changes in harm perception and associated predictors. The results suggest that perception of ENDS as less harmful than cigarettes significantly decreased from 54.3% at Wave 1 (2013) to 30.4% at Wave 4 (2018) (P < 0.001). Perception of ENDS as no or little harm decreased from 35.9% at Wave 1 to 16.9% at Wave 4 (P < 0.001). These changes in harm perception were less robust among males, adolescents who did not have positive tobacco-related attitudes, and those with smoke-free home rules (P's < 0.05). Additionally, having ever used ENDS or alcohol were more likely to be associated with reduced ENDS-related harm perception over time (P's < 0.05). Our results show that while ENDS-related harm perception have generally increased, this does not appear to be equally experienced across all adolescents, potentially highlighting the importance of at-risk groups and targets for intervention. This study can help identify individuals at risk of ENDS initiation because of their favorable ENDS harm perception profile, as well as guide the development of ENDS risk communication interventions for adolescents.

INTRODUCTION: The 21st century was marked by a dramatic increase in adolescent e-cigarette use in the United States (US). The popularity of non-traditional flavor types, including fruit and pastry, is thought to contribute toward growing product use nationally, leading to a variety of federal and state regulations limiting the use of non-traditional flavors in the US. The relationship between flavor type and increased adolescent use suggests a possible link between flavor use and addiction and harm perception. This study assessed if the flavor type used when initiating e-cigarette use predicted addiction and harm perceptions. METHODS: The study utilized data from the multi-wave youth Population Assessment of Tobacco Health Study. It explored the impact initiating e-cigarette use with traditional versus non-traditional flavor types among cigarette users on the outcome variables: e-cigarette addiction and harm perception. Both e-cigarette addiction and harm perception were measured using self-report, Likert scale questionnaires. Descriptive statistics characterized the study variables and linear regression analyses performed to test whether flavor initiation type is associated with addiction and harm perception. RESULTS: The study sample consisted of 1,043 youth (weighted N = 1,873,617) aged 12 to 17 years who reported at least one instance of e-cigarette use. After adjusting for age, age of onset, sex, race and annual household income there was no statistically significant difference in addiction levels between those initiating with traditional versus non-traditional flavors (p = 0.294). Similarly, traditional versus non-traditional flavor initiation did not show a statistically significant difference in adolescent e-cigarette harm perceptions (p = 0.601). CONCLUSIONS: Traditionally flavored e-cigarette initiation produces similar risk for addiction and harm perceptions as non-traditionally flavored initiation. These findings suggest that banning non-traditional flavors alone may be ineffective in curbing e-cigarette addiction and harm perception. Additional research is needed to better understand which e-cigarette product characteristics and behaviors may be associated with greater addiction and reduced harm perceptions.

Background: National estimates of electronic vaping product (EVP) use exist, but little is known about young adult EVP users who interact with the healthcare setting. Methods: Cross-sectional survey of 18-25 year olds receiving care in our ambulatory medical practice. Population differences were evaluated with the chi square test reporting unadjusted odds ratios (ORs). Results: Response rate was 16.6% (n = 1,017/6,119). The prevalence of ever EVP use was 46.0% of whom 13.9% used every day. Each additional day of alcohol use (past 30 days) was associated with increased odds of being an EVP user (OR = 1.06, 95% CI 1.02-1.09), and cannabis use (past 30 days) was associated with a higher odds of being an EVP user compared to non-cannabis users (OR = 40.0, 95% CI 17.4 - 111.8). Observing a biological parent (OR = 2.89, 95% CI 1.98-4.24), step parent (OR = 2.03, 95% CI 1.02-4.19) and full sibling (OR = 2.31, 95% CI 1.78-3.00) using inhaled substances (past 30 days) was associated with increased odds of being an ever EVP user. Ever EVP users had lower odds than never users to report that EVPs with nicotine are "a little" or "a lot" more harmful than smoking "regular" tobacco cigarettes (OR = 0.53, 95% CI 0.37 - 0.76). Conclusion: Our survey is limited by a low response rate but confirms observed associations between EVP use and substance use and social influences. Our data also suggest that professionals should regularly screen for EVP use among young people, especially those with exposure to family members who used inhaled substances.

BACKGROUND: Electronic cigarettes (e-cigarettes) have been characterised as significantly less harmful than cigarettes by many health agencies and regulators globally. In this study, we examined to what extent perceived relative harms of e-cigarettes compared to cigarettes have changed in the USA. METHODS: We analysed the data from the longitudinal and nationally representative, Population Assessment of Tobacco and Health Study to assess the relative perceived harm of e-cigarettes amongst US adults between 2013 and 2016. RESULTS: The proportion of US adults who correctly perceived e-cigarettes as less harmful than cigarettes decreased each year from 41.1% (CI 40.1-42.1%) in 2013-2014, 31.5% (CI 30.8-32.2%) in 2014-2015 and 25.3% (CI 24.6-26.0%) in 2015-2016. Concurrently, the proportion of US adults who perceived e-cigarettes as equally, or more, harmful than cigarettes increased from 53.7% (CI 52.3-55.1%), 64.9% (CI 63.6-66.2%) to 72.7% (CI 71.5-73.9%) respectively. The proportion of US adults who held negative relative harm perceptions of e-cigarettes increased regardless of current smoking or vaping status by 24.6% and 29.6% respectively within 3 years. In Wave 3, the proportion of current smokers who perceived the relative harm of e-cigarettes as less harmful was lower at 29.3% (CI 28.2-30.4%) compared to current e-cigarette users at 43.5% (CI 40.3-46.7%). Former smokers who used e-cigarettes and believed that they were equally, or more, harmful than cigarettes in 2014-2015 had significantly higher rates of smoking relapse in the following year, 29% and 37% (p < 2.2e-16), respectively, compared to those with positive relative harm perceptions who reported relapse rates of 19%. CONCLUSIONS: 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. Further research is required to elucidate why the relative harm of e-cigarettes is misunderstood and continues to deteriorate.

Perceptions of harm and addictiveness are associated with smoking combusted cigarettes, but these factors have not been fully explored for e-cigarettes. Specifically, little is known about the perceived harm and addictiveness of e-cigarettes, or whether information-seeking about e-cigarettes is related to trying e-cigarettes. We aimed to determine the relationship between (1) perceived e-cigarette harm and addictiveness and trying e-cigarettes; (2) nicotine perceptions and trying e-cigarettes; and (3) e-cigarette information-seeking, Internet use, and trying e-cigarettes. We used data from the nationally representative 2015 Health Information National Trends Survey-FDA (HINTS-FDA 2015). Weighted multivariable logistic regression models assessed independent associations between perceived e-cigarette harm, perceived e-cigarette addictiveness, nicotine perceptions, e-cigarette information-seeking, personal Internet use, and trying e-cigarettes, among 3195 adults. Compared to people who believed e-cigarettes were equally or more addictive than combusted cigarettes, those who believed e-cigarettes were less addictive had 2.49 times the odds of trying e-cigarettes (95% confidence interval [CI]: 1.30, 4.74). Perceived e-cigarette harm and nicotine perceptions were not associated with trying e-cigarettes. The positive association between e-cigarette addictiveness and trying e-cigarettes coupled with the lack of an association between nicotine perceptions and trying e-cigarettes suggests people do not fully understand that e-cigarettes contain nicotine and therefore could be addictive. People most frequently reported searching for information about potential health effects of e-cigarettes (37.9%), indicating that people are interested in learning about the potential impact of e-cigarette use on their health. People who searched for information about e-cigarettes had 10.23 higher odds of trying e-cigarettes (CI: 5.41, 19.33).

BACKGROUND: Health disparities associated with e-cigarette use are increasingly apparent among US adolescents. Perceptions of e-cigarette harm and addiction play an important role in understanding adolescents' e-cigarette use behavior. The objective of this systematic review is to examine racial/ethnic and socio-economic disparities in e-cigarette harm and addiction perceptions among US adolescents. METHODS: We searched five databases to identify cross-sectional or longitudinal studies that focused on adolescents (≤ 18 years of age) who were ever, current, or never e-cigarettes users; we then examined how race/ethnicity and/or socio-economic status (SES) impacted e-cigarette harm and/or addiction perceptions. Two co-authors independently identified relevant studies, extracted data, and assessed the risk of bias. RESULTS: Adhering to PRISMA guidelines, eight of 226 identified studies met the inclusion criteria. These eight studies examined either perceptions regarding absolute e-cigarette harm and/or addiction (i.e., assessing perception of only e-cigarette) or relative e-cigarette harm and/or addiction (i.e., comparative perceptions to traditional cigarettes) by race and ethnicity. Two of the eight studies assessed absolute harm and/or addiction perceptions of e-cigarettes by SES. Our results indicate that, compared to all other racial/ethnic groups, relative e-cigarette harm and addiction perceptions were lower among Non-Hispanic White adolescents; however, absolute e-cigarette harm perception was higher among these groups. No clear patterns of racial/ethnic differences in absolute e-cigarette addiction perceptions and SES differences in absolute e-cigarette harm perceptions were reported. CONCLUSION: More research is needed to explicitly assess perceptions of e-cigarette harm and addiction among US adolescents by race/ethnicity and SES to develop subgroup appropriate public health messaging.

BACKGROUND: Prior research indicates a direct, short-term effect of e-cigarette advertising on e-cigarette use among youth. This study seeks to investigate the long-term effects of e-cigarette advertisements and disparities in exposure among adolescents with different levels of internalizing problems. METHODS: Panel data of the Population Assessment of Tobacco and Health (PATH) Study Waves 3-5 (2015-2019) were analyzed. Youth aged 12-17 who were non-e-cigarette users at the time of Wave 3 were included (n = 4,678). A moderated mediation model was employed to examine the mediating role of perceived harm of e-cigarettes and the moderating effect of internalizing problems. RESULTS: Exposure to e-cigarette advertisements in Wave 3 predicted lower harm perception of e-cigarette in Wave 4 (bp = -0.055, p <.01), leading to more e-cigarette use in Wave 5 (bp = -0.042, p <.001). While e-cigarette advertisements exhibited a lasting indirect effect (bp = 0.002, p <.05), there was no long-term direct effect (bp = 0.017, p >.05) on youth e-cigarette use. Furthermore, a moderating effect of internalizing problems was observed (bp = 0.107, p <.05). CONCLUSIONS: E-cigarette advertisements can exert a lasting influence indirectly by diminishing harm perception, particularly among those with lower internalizing problems. Adolescents with higher internalizing problems exhibit lower susceptibility to advertisement influence, yet their perceived harm of e-cigarettes is notably lower than their peers with fewer internalizing problems. These disparities underscore the need for tailored prevention strategies: implementing anti-e-cigarette education programs for adolescents with low internalizing problems and providing mental health care for those facing internalizing challenges. Regulatory measures targeting e-cigarette advertising are also crucial.

Objective: Synthetic nicotine (SN) e-cigarettes emerged on the market as an alternative to tobacco-derived nicotine (TDN) vaping products. It is critical to understand the harm perceptions, purchase, and use of SN vs. TDN e-cigarettes. Methods: From November 2021 to February 2023, we conducted intercept interviews with 263 adult customers at 37 vape shops in Southern California. Self-reported use and harm perceptions towards SN vs TDN e-cigarettes were examined. A qualitative analysis of researcher-obtained photographs of vaping items just purchased by customer participants was conducted. Results: Past 30-day SN e-cigarette use was reported by 44 (16.7 %) customers. Past 30-day SN e-cigarette users vs. non-users reported vaping on more days in the past month (29.3 vs. 26.1 days, p = 0.02). Overall, 23.8 % of participants perceived SN e-cigarettes as less harmful than TDN ones; never-smoking vapers and dual users perceived SN e-cigarettes as less harmful than salt-based TDN e-cigarettes. Among 44 customers who purchased SN products (verified through qualitative analysis of photographs), only 13 (29.6 %) self-reported using SN products in the past month, while 5 (11.4 %) indicated they were not aware of the existence of SN products. Most SN vaping products (71.4 %) displayed a modified "tobacco-free" warning label. Conclusions: Misperceptions about SN e-cigarettes were documented in this study, including the perception that SN is either less or more harmful than TDN. Further, some customers may be unknowingly purchasing and using SN e-cigarettes. Regulating "tobacco-free nicotine" terminology in SN vaping products marketing is suggested. SN product labeling should not imply that SN is safe/safer than TDN.
RESUMO
PURPOSE: To evaluate the trend of harm perception for e-cigarettes and the trend of the association between harm perception for e-cigarettes and for cigarettes among US youth from 2014 to 2019. DESIGN, SETTING AND SUBJECTS: The National Youth Tobacco Survey is an annual, cross-sectional, school-based survey done among youth selected using three-stage probability sampling. ANALYSIS: Data were drawn from the 2014 to 2019 Surveys. A Multinomial logistic regression model was used to assess the association between harm perception for e-cigarettes and harm perception for cigarettes for each year. RESULTS: The percentage of youth who perceived e-cigarettes as harmless decreased from 2014 to 2019 (17.2% to 5.8%). From 2015 to 2018, the percentage of smokers who perceived e-cigarettes as a little harmful increased (33.6% to 41.2%). The positive association between harm perception for e-cigarettes and harm perception for cigarettes became stronger with time. In 2014, the odds of perceiving e-cigarettes as harmless relative to very harmful were 19.55 times greater for youth who perceived cigarettes as harmless, compared to those who perceived cigarettes as very harmful (OR = 19.55; 95% CI: 14.19-26.94). These odds increased to 77.65 times in 2019 (OR = 77.65; 95% CI: 41.48-107.85). CONCLUSION: This study suggests a stronger relationship between perceived harm of cigarettes and e-cigarettes with time. Interventions to prevent smoking have the potential to change e-cigarette use.

BACKGROUND: This study investigates how ENDS harm perception influences ENDS initiation over time among US young people. METHODS: Data were from the sample of the Population Assessment of Tobacco and Health (PATH) Study conducted from 2013 to 2018. The Cox proportional hazards regression models were used to assess the relationship between absolute (the perception of harm from ENDS only) and relative harm perception (ENDS' harm relative to cigarettes) and ENDS initiation among adolescents (12-17 years) and young adults (18-24 years) separately. Harm perception was assessed at the wave before ENDS initiation in a subsequent wave. Weighted results were reported. RESULTS: Of the 11,633 adolescents and 5089 young adults from baseline, 17.1% and 25.5% initiated ENDS use across four waves, respectively. Among adolescents (HR=2.31; 95%CI: 1.95-2.73) and young adults (HR=1.97; 95%CI: 1.69-2.30), perceiving lower relative harm of ENDS significantly predicted ENDS initiation in subsequent waves. Among adolescents, perceiving lower absolute harm of ENDS (HR=2.18; 95%CI: 1.83-2.60) predicted ENDS initiation in subsequent waves. Additionally, adolescents and young adults who ever used any other tobacco products or alcohol and lived with anyone who used tobacco were more likely to initiate ENDS use. CONCLUSIONS: Among a representative longitudinal cohort of adolescents and young adults who had never used ENDS at baseline, perceiving ENDS as reduced or low-harm products significantly predicted ENDS initiation in subsequent waves. These findings underscore the importance of ENDS harm perception and the central role of risk communication strategies that need to target those young people at particular risk of unwarranted ENDS use.

PURPOSE: Perceived harm is associated with substance use. Changes in product and policy landscapes may impact perceived harms of tobacco and cannabis. This study aimed to examine changes in young adults' perceived harms of tobacco and cannabis and their associations with use behavior during a period including both before and after legalization of cannabis. METHODS: We conducted a panel survey of California Bay Area young adults (mean age = 23.5 years old, 64.4% female) in 2014 and 2019-2020. Participants (N = 306) reported past 30-day use and perceived harms of tobacco and cannabis at both waves. Perceived harms to health of cannabis and tobacco (cigarettes, e-cigarettes, hookah, smokeless tobacco, and secondhand tobacco smoke) were measured from 1-"Not at all harmful" to 7-"Extremely harmful." Mixed-effects logistic regressions examined associations between perceived harms and use of tobacco and cannabis, controlling for demographics. RESULTS: Participants perceived lower harm for cannabis than for tobacco products. Perceived harms of e-cigarettes, hookah, and smokeless tobacco significantly increased over time; while perceived harms of cigarettes, secondhand tobacco smoke, and cannabis did not change. Increased perceived harm of e-cigarettes was associated with lower odds of any tobacco use (OR = 0.72, 95%CI = 0.56, 0.92), and increased perceived harm of cannabis was associated with lower odds of any cannabis use (OR = 0.51, 95%CI = 0.42, 0.62). CONCLUSIONS: Findings suggest that perceived harms of e-cigarettes and cannabis play important roles in driving young adult use behaviors. Risk communication efforts that increase perceptions of health harms related to e-cigarettes and cannabis may decrease use of tobacco and cannabis among young people.

OBJECTIVES: The use of alternative nicotine products by middle and high school students is a growing concern due to industry marketing techniques, availability, and popularity of new products, and ambiguous nicotine concentrations. The 2021 National Youth Tobacco Survey (NYTS) provides information about the frequency, and characteristics of middle, and high school students who have used nicotine pouches. METHODS: The National Youth Tobacco Surveys provide important information about the frequency of use of tobacco and alternative nicotine products by a representative sample of students in schools in the United States. The 2021 survey included questions about the use of nicotine pouches/dissolvable tobacco products. The results from the survey were analysis using descriptive statistics, and logistic regression to model the association between the use of these alternative nicotine products, and the use of electronic cigarettes or the use of conventional cigarettes. RESULTS: A total of 20 413 students participated in the survey year 2021; 17 842 were included in the final data analysis. Their ages ranged from 9 to 18+. Identified risk factors for the use of alternative nicotine products included race, and age. The adjusted odds ratio (OR) was lower in non-Hispanic Black and Hispanic students, as compared to non-Hispanic White students. Older students had a substantially higher risk of using nicotine/dissolvable tobacco products, specifically, compared to students less than or equal to 13 years old. The OR increased 174% (OR: 2.74; 1.70-4.41) in 17-year-old students. The perception of harm associated with electronic cigarettes increased the likelihood of using alternative nicotine products. Students who did not smoke cigarettes (OR: 0.39; 0.27-0.56) or did not smoke electronic cigarettes (OR: 0.20; 0.18-0.40) had significantly lower OR for using alternative nicotine products. CONCLUSIONS: The 2021 National Youth Tobacco Survey indicates that a relatively small percentage of middle school and high school student have used nicotine pouches. However, with the increase in new, alternative tobacco products, understanding adolescent use in comparison to other tobacco products is an important trend to monitor.

PURPOSE: The aim of this study is to examine US youths' harm perceptions toward nondaily use of e-cigarettes, cigarettes, cigars, smokeless tobacco, and hookahs. METHODS: The nationally representative, cross-sectional National Youth Tobacco Survey annually assessed the following: "How much do you think people harm themselves when they [use tobacco products] some days but not every day?" Weighted estimates for 2020 were generated overall (grades 6-12) and by select demographics. Multivariable regression examined linear and quadratic changes during 2016-2020 (excluding cigars). RESULTS: In 2020, the prevalence of middle and high school students reporting "no" or "little" harm (vs. "some" or "a lot") was 20.1% for e-cigarettes, 17.4% for hookahs, 14.6% for cigars, 13.5% for smokeless tobacco, and 11.0% for cigarettes. During 2016-2020, perceptions of "no" or "little" harm decreased for e-cigarettes, increased for cigarettes and smokeless tobacco, and exhibited nonlinear changes for hookahs.

INTRODUCTION: Electronic cigarette (e-cigarette) harm perceptions and information seeking behaviours are both important antecedents of e-cigarette use, yet the relationship between them has been rarely studied. We assessed how absolute (e-cigarettes are harmful to my health) and relative harm perceptions (e-cigarettes are more/less harmful than cigarettes) were associated with specific e-cigarette information seeking behaviours in a sample of current, former and never cigarette smokers. METHODS: We used data from US adults in two cycles of the Health Information National Trends Survey (HINTS-FDA 2015, n = 3738; 2017, n = 1736). Analyses controlled for socio-demographics, ever e-cigarette use and survey cycle. Data were analysed between January and August 2020. RESULTS: Higher relative harm perceptions were associated with lower odds of having sought any information on e-cigarettes [adjusted odds ratio 0.61, 95% confidence interval (0.48, 0.84)] and on how to use e-cigarettes to quit smoking specifically [adjusted odds ratio 0.59, 95% confidence interval (0.38, 0.91)]. Smoking status did not moderate associations between absolute or relative harm perceptions and information seeking behaviours, nor was it associated with specific information seeking behaviours after adjusting for covariates. DISCUSSION AND CONCLUSIONS: The risks of e-cigarettes relative to combusted cigarettes (as opposed to the absolute risks of e-cigarettes) appear to be more important in individuals' information seeking behaviours about e-cigarettes. Public health messages could ensure that all individuals understand how one's health risk would change if they exclusively used e-cigarettes, switched to e-cigarettes completely or used both products.

BACKGROUND: The growth in e-cigarette use may be driven by the perception that they are a safer, healthier alternative to conventional cigarettes. However, their long-term health implications are not well known and use is discouraged by most cancer societies. It is currently unclear how cancer survivors perceive the risks associated with e-cigarette and how this may influence use in this population. METHODS: A cross-sectional analysis was conducted using the Health Information National Trends Survey (HINTS) (Years 2017-2019). Our primary study outcome was the perception of harm associated with e-cigarettes compared to traditional cigarettes among adults with and without a self-reported history of cancer. We used logistic regression analyses assessing the association of a cancer history with the perception that e-cigarettes are as much or more harmful than cigarettes. RESULTS: A total of 11,846 respondents (weighted population estimate 243,728,483) were included. Of these, 26.6% reported a history of cancer. The proportion of cancer survivors who perceived e-cigarettes to be as much or more harmful than conventional cigarettes was similar to non-cancer respondents (70.6% vs 68.3%, P = 0.35). There was no difference in perception of harm among cancer and non-cancer respondents, adjusted for sociodemographic factors (OR 0.82, 95% CI 0.6-1.1). Past (OR 9.06, 95% Cl 5.06-16.20) and never e-cigarette use (OR 23.40, 95% Cl 13.56-40.38) as well as having a history of cardiopulmonary disease (OR 1.28, 95% Cl 1.05-1.56) was associated with higher odds of perceiving e-cigarettes to be as much or more harmful. CONCLUSION: Cancer survivors commonly perceive e-cigarettes to be as much or more harmful than traditional cigarettes though these findings are similar to perceptions among adults without a history of cancer. There is a strong association with avoidance of e-cigarette products among those who perceive them to be harmful.

New tobacco and nicotine-containing products are gaining more popularity among young people. The aim of this study is to assess the prevalence in the perception of e-cigarettes and heated tobacco among young people in Poland and to assess the factors that are positively correlated with this perception. A cross-sectional study covering almost 12,000 adolescents aged 13-18 was carried out in January and February 2020. Data were collected through a detailed questionnaire recommended for monitoring tobacco use by adolescents. The results of the study showed that 52.2% and 61.9% of young people perceive e-cigarettes and heated tobacco products as less harmful compared to traditional cigarettes, respectively. The risk of perceiving these products as less harmful than smoking was higher among older adolescents, males, those who used these products, had a family member who used e-cigarettes/heated tobacco products and those who were exposed to tobacco advertising. Our study indicates the need to consider the coexistence of traditional smoking, e-cigarettes and heated tobacco and its impact on the assessment of the harmfulness of these products. More research is needed to better understand how perceptions of the harmfulness of e-cigarettes and heated tobacco affect their subsequent use.
