RESUMO
INTRODUCTION: Flavors with names describing blended tastes/sensations or with ambiguous terminology ("concept flavors") are available on the e-cigarette market. AIMS AND METHODS: This study investigates adolescent and young adult use and sensory perceptions of blended and concept flavors. Current e-cigarette users aged 15-24 years (N = 2281) completed an online convenience sample survey (October 20-November 23, 2020) and rated the sensory attributes (fruity, cooling, sweet, and minty) of their current flavor(s) using nine-point scales. T-tests compared mean sensory perception scores within and between flavors. To compare concept flavors to blends, reference categories used the average of blends with relevant descriptors: fruit (Banana Ice, Iced Mango, Melon Ice, Cool Cucumber); cooling (Banana Ice, Iced Mango, Melon Ice, Blue B Ice, Cool Cucumber, Lush Ice, and Menthol Purple); sweet (Vivid Vanilla) and mint (Mint-sation). RESULTS: Most respondents had used at least one product with blended descriptors (74.8%) or concept flavor (57.9%) in the past 30 days. All flavors had high perceived strength for at least two sensory attributes. Mint taste was not perceived to be a strong sensory characteristic for all but two flavors (Mint-sation and Winter) in the study. The most commonly used flavors used blended descriptors (Iced Mango was used by 30.2% of the sample; Banana Ice: 26.2%; Lush Ice: 23.8%; Melon Ice: 22.9%). Some concept flavors did not significantly differ from flavor blend reference categories for strength of: fruit taste (Bahama Mama and Tropic); cooling sensation (Marigold, Island Breeze, Winter); sweet taste (Bahama Mama, Honeymoon, Island Breeze, Island Cream, Meteor Milk, OMG, Royal Dagger and Tropic); and mint taste (Winter). CONCLUSIONS: Blended and concept flavors are used by most young e-cigarette users, who describe these products as fruity, sweet, and cooling. A variety of flavored products with high youth appeal are available in the U.S. market. IMPLICATIONS: This study of adolescent and young adult e-cigarette users finds evidence of the popularity of e-cigarette flavors combining a cooling sensation with fruity and sweet flavorings. Some products with this flavor profile do not use characterizing descriptors. Findings inform public health interventions intended to reduce e-cigarette use in young people.

BACKGROUND: While much is known about the influence of tobacco control spending on the demand for conventional cigarettes, little is known about the effects of tobacco control spending on the demand for electronic cigarettes (e-cigarettes). This study provides the first evidence on the association between state tobacco control spending and high school student vaping in the USA. METHODS: We used data from the 2015 through 2019 National Youth Risk Behavior Surveys to estimate vaping prevalence and vaping intensity demand equations. We employed logistic regressions to estimate the vaping prevalence equations and generalised linear models with log-link and gamma distribution to estimate the vaping intensity equations. RESULTS: We found evidence that funding for state tobacco control programmes had a significant negative association with both vaping prevalence and vaping intensity among high school students in the USA. Our results indicate that a 50% increase in state spending on tobacco control during the time of the surveys would have been associated with a 7.46% lower high school student vaping prevalence rate than what was observed. CONCLUSIONS: There has been a dramatic increase in e-cigarette use by adolescents and young adults in the USA. The rapid rise in e-cigarette use has been a significant source of public policy concern for many states. The results of this study strongly suggest that increased spending on tobacco control programmes will reduce the number of high school students who vape and will decrease the number of days vaping products are used by high school students. These findings should be extremely valuable to policymakers interested in curbing the youth vaping epidemic in the USA.

BACKGROUND: Mass media campaigns have been shown to be effective in reducing cigarette use. However, evidence is limited for whether campaigns can shift e-cigarette use among youth and young adults (YYA). To assess the impact of the truth anti-e-cigarette campaign, which focused on the effects of vaping on mental health, this study examines the relationship between campaign awareness and e-cigarette behaviour among YYA. METHODS: Data from weekly cross-sectional surveys of YYA aged 15-24 years from September 2021 to October 2022 were used for multilevel models assessing how weekly campaign awareness is related to intentions to use e-cigarettes and current e-cigarette use (past 30 days). Weekly campaign awareness was calculated by averaging individual-level awareness for each week. Control variables included individual-level campaign awareness, sociodemographics, perceived financial situation, parental smoking, sensation seeking, and mental health. RESULTS: Weekly campaign awareness ranged from 50% to 78%, with most weeks (77%) being within 65% and 75% of weekly campaign awareness. At weekly awareness levels between 65% and 75%, there was a significant association with lower intentions to use e-cigarettes. A dose-response relationship was observed for current use: compared with weeks with lower (<65%) awareness, weeks with awareness of 65-70% had 14% lower odds of current use, weeks with 70-75% awareness had 16% lower odds and weeks with >75% weekly awareness had 18% lower odds (p=0.018, p=0.009 and p=0.007, respectively). CONCLUSIONS: Findings from this analysis of weekly campaign awareness demonstrate that exposure to the truth anti-e-cigarette campaign is associated with significantly lower odds of intentions to use and current use of e-cigarette among YYA.
RESUMO
BACKGROUND: E-cigarette promotion on social media coincided with the rapid growth of e-cigarette use among American youth, particularly with the increased JUUL pod vaporiser use. We examined commercial JUUL-related messages on Instagram to identify marketing appeals used to target users along the continuum of e-cigarette use; we mapped the appeals to existing theoretical marketing frameworks to better understand industry strategies. METHODS: Hashtag-based keyword rules were used to collect JUUL-related posts from the Instagram application programming interface, 1 March-13 November 2018. Posts were classified as commercial or non-commercial. A combination of machine learning methods, keyword algorithms and human coding were used to characterise message themes in commercial posts. RESULTS: Keyword filters captured 50 817 relevant posts and 41% were commercial. Among commercial posts, 91% contained recruitment/trial-based appeals (eg, combustible tobacco cessation; product sampling; giveaways) and 71% featured reinforcement/addiction-related appeals (eg, loyalty programmes). None of the commercial messages contained e-cigarette cessation-related appeals and less than 25% mentioned quitting combustible tobacco as a recruitment appeal. CONCLUSIONS: Instagram posts featuring e-cigarette related marketing can increase exposure to persuasive messages encouraging e-cigarette trial and use particularly among susceptible youth. Stronger regulations are needed to prevent exposure to social media marketing among young social media users.

BACKGROUND: The E-cigarette, or Vaping Product-Use Associated Lung Injury (EVALI) Outbreak of 2019 hospitalised thousands and killed dozens of people in the USA and raised perceptions of the dangers posed to health by electronic cigarettes (e-cigarettes). These illnesses along with continued increases in youth vaping rates lead to the passage of many state and federal laws intended to curtail the sale of flavoured e-cigarettes. Little is known about the impact of these events on US e-cigarette and cigarette retail sales. METHODS: Using Nielsen Scantrack sales data from January 2014 to January 2020 for 23 US states, we evaluate the effect of the EVALI outbreak. First-differenced state-panel regressions tracking unit sales of total-level and category-level e-cigarettes and cigarette sales controlling for price, Tobacco 21 policy coverage, product distribution, seasonality, EVALI-attributable deaths, and state-level e-cigarette policies affecting the availability of e-cigarettes (non-tobacco flavoured and total) were employed. RESULTS: Dollar sales of e-cigarettes declined 29% from their pre-EVALI peak by January 2020. Total sales of e-cigarettes declined in response to EVALI deaths and the total e-cigarette sales ban put in place in Massachusetts adopted in its wake. Cigarette sales were largely unchanged by either the direct or indirect policy effects of the EVALI outbreak, except for in Massachusetts, where cigarette sales-particularly those smoked by young people-rose temporarily after a total ban on e-cigarette sales. CONCLUSION: Sales of e-cigarettes declined in response to the EVALI outbreak and from the most restrictive regulatory policies that were adopted in response, while sales of cigarettes were affected less.

INTRODUCTION: Little is known on whether cigarette filter-related knowledge or beliefs are associated with support for policies to reduce their environmental impact. METHODS: A cross-sectional, population-based sample of US adults aged 18-64 years (n=2979) was used to evaluate filter-related knowledge and beliefs by smoking status using data collected between 24 October 2018 and 17 December 2018. Multivariate logistic regression models explored whether these knowledge and belief items were associated with support for two policies, a US$0.75 litter fee and a ban on sales of filtered cigarettes, controlling for demographic characteristics and smoking status. RESULTS: Regardless of smoking status, 71% did not know plastic was a cigarette filter component and 20% believed filters were biodegradable. Overall, 23% believed filters reduce health harms and 60% believed filters make it easier to smoke; 90% believed cigarette butts are harmful to the environment. Individuals believing cigarette butts harmed the environment were more likely to support a litter fee (adjusted OR (aOR)=2.33, 95% CI: 1.71 to 3.17). Individuals believing that filters are not biodegradable had higher odds of supporting a litter fee (OR=1.47, 95% CI: 1.15 to 1.88). Respondents believing that filters do not make cigarettes less harmful were more likely to support a litter fee (aOR=1.50, 95% CI: 1.20 to 1.88) and filter ban (aOR=2.03, 95% CI: 1.64 to 2.50). Belief that filters make it easier to smoke was associated with decreased support for a filter ban (aOR=0.69, 95% CI: 0.58 to 0.83). CONCLUSIONS: Comprehensive efforts are needed to educate the public about the impact of cigarette filters in order to build support for effective tobacco product waste policy.

OBJECTIVE: Antismoking mass media campaigns have contributed to significant declines in combustible tobacco use among young people. This study evaluates a national anti-e-cigarette campaign to determine its association with knowledge, attitudes and beliefs in the context of increasing e-cigarette use in the USA. METHODS: A national sample of respondents aged 15-24 years (n=8421) was drawn from a repeated cross-sectional online panel survey (220 participants/week) (October 2018 to December 2019). Self-reported exposure to the truth anti-e-cigarette campaign was measured according to level of ad awareness. Outcomes were subjective knowledge of campaign-targeted facts about e-cigarettes and attitudinal constructs about perceived e-cigarette harm, social unacceptability and anti-industry sentiments. Covariates included respondent demographics, current e-cigarette use and cigarette use, parental smoking, sensation seeking, mental health and growth in e-cigarette sales. RESULTS: Ad awareness was associated with knowledge that e-cigarette users are more likely to start smoking (low OR: 1.28, 95% CI 1.14 to 1.44; high OR: 1.88, 95% CI 1.66 to 2.13) and of the nicotine content of JUUL compared with cigarettes (low OR: 1.63, 95% CI 1.45 to 1.82; high OR: 2.50, 95% CI 2.21 to 2.84). High ad awareness was associated with knowledge that the long-term health effects of JUUL use are unknown (OR: 1.88, 95% CI 1.57 to 2.28). High ad awareness was associated with significantly higher perceived product harm (OR: 1.35, 95% CI 1.18 to 1.54), social unacceptability (OR: 1.32, 95% CI 1.15 to 1.53) and anti-industry attitudes (OR: 1.40, 95% CI 1.21 to 1.62), compared with respondents with no awareness. CONCLUSIONS: Young people with awareness of anti-e-cigarette ads demonstrate higher levels of campaign-targeted knowledge, attitudes and beliefs. Future campaign evaluation priorities include measuring the campaign effects on e-cigarette use behaviours.

BACKGROUND: E-cigarettes are the most-commonly used tobacco product by youth since 2014. To prevent youth access and use of e-cigarettes, many U.S. states and localities have enacted policies over a relatively short period of time. The adoption of these policies has necessitated timely data collection to evaluate impacts. METHODS: To assess the impact of flavored e-cigarette policies in select states and local jurisdictions across the United States, a multi-method, complementary approach was implemented from July 2019 to present, which includes analyses of cross-sectional online surveys of young people ages 13-24 years with retail sales data. RESULTS: From February 2020 through February 2023, cross-sectional surveys have been conducted in three cities, one county, and eight states where policy changes have been enacted or are likely to be enacted. Data collection occurred every six months to provide near real-time data and examine trends over time. Additionally, weekly retail sales data were aggregated to showcase monthly sales trends at the national level and for the selected states. DISCUSSION: This rapid and efficient method of coupling online survey data with retail sales data provides a timely and effective approach for monitoring a quickly changing tobacco product landscape, particularly for states and localities where rapidly-available data is often not available. This approach can also be used to monitor other health behaviors and relevant policy impacts.

Background: E-cigarette device types vary in the amount of nicotine delivered to users. Given that youth and young adults are using pod-based and disposable e-cigarettes with high nicotine concentrations, it is important to determine how e-cigarette use behaviors associated with nicotine dependence may differ across e-cigarette device type. Methods: Baseline information was collected from September 2020 to March 2021 and follow-up information was collected from July to October 2021 from the Truth Longitudinal Cohort. The final analytic sample included respondents (aged 15-24) who reported current use of e-cigarettes at either baseline or follow-up and provided information on the 4-item E-cigarette Dependence Scale (EDS). Differences in endorsement of items from the EDS by e-cigarette device type (pod-based, disposable, or tank) were assessed using chi-square tests. Results: Participants (N = 308) were evenly split on age (15-20, 21+) and gender. Most 15-20-year-olds used disposable e-cigarettes, while those 21+ years primarily used tank devices. Although EDS score did not differ by e-cigarette device type, positive endorsement of two items from the EDS significantly differed by e-cigarette device type. More tank users endorsed reaching for a device without thinking about it (tank: 92.6%; pod-based: 79.0%; disposables: 79.9%, p = 0.04) and vaping more before going into a situation where vaping is not allowed (tank: 92.9%; pod-based: 71.0%; disposables: 73.0%, p < 0.01). Conclusions: Findings have the potential to inform policy implementation by providing evidence for specific targets for regulatory action that can help to reduce the burdens of e-cigarette use among youth and young adults, as results suggest that tank device users are more likely to endorse use behaviors associated with nicotine dependence.

BACKGROUND: Unacceptably high levels of e-cigarette use among youth paired with growing research about the dangers of vaping demonstrate a critical need to develop interventions that educate young people to reject e-cigarette use and promote cessation for current users. Vaping: Know the Truth (VKT) is a free digital learning experience prioritizing middle and high school students that aims to improve students' knowledge about the dangers of using e-cigarettes and provide quitting resources for those who already vape. The current study was designed to evaluate whether students receiving the curriculum increased knowledge of the dangers of vaping. METHODS: The outcome measures were calculated as the change in the number of correct responses from the pre- to post-module assessments among middle and high school students who completed four modules of the VKT curriculum (N = 103,522). Linear regression was performed to determine the association between the student's pre-module assessment score and the knowledge change score after completion of the four modules. RESULTS: Students' e-cigarette knowledge significantly improved by an average of 3.24 points (SD: 3.54), following implementation of the VKT curriculum. This indicates that participants answered more than 3 additional questions correctly, on average, after the intervention. CONCLUSION: Findings demonstrate that the Vaping: Know the Truth curriculum is an effective resource for increasing knowledge among youth about the harms associated with e-cigarette use. Further research is needed to evaluate whether the intervention is associated with behavioral outcomes over time.
RESUMO
OBJECTIVES: To assess the quality of evidence on the effectiveness of local US laws restricting the sale of flavored tobacco products. METHODS: We conducted a systematic search and qualitative scoping review of English-language papers published through May 2020 that evaluated flavored tobacco sales policies implemented by US jurisdictions during 2010-2019. We constructed a conceptual model for flavored and menthol tobacco sales restriction outcomes, assigned GRADE quality of evidence ratings to policy outcomes evaluated through the included studies, and summarized factors that might explain weak or inconsistent findings. RESULTS: We found moderate to high quality of evidence associating policy implementation with reduced availability, marketing, and sales of policy-restricted products, and decreased youth and adult tobacco use of these products; however, policy exclusions and exemptions, implementation challenges, tobacco industry actions (e.g., marketing of concept-named flavored products; exploiting policy exemptions for certain store types), and consumer responses (e.g., cross-border or illicit purchasing) might undermine or mitigate intended policy effects. CONCLUSIONS: Flavored and menthol tobacco product sales restrictions implemented and evaluated in US jurisdictions appear to have achieved some of their intended outcomes; however, deficiencies in study designs, methods, and metrics could contribute to equivocal findings on quality of evidence associating policy implementation and outcomes. Gaps in the evidence are beginning to be filled with research using more rigorous study designs, improved measurement and analytic methods, and longer-term follow-up. IMPLICATIONS: In the absence of comprehensive federal action, US jurisdictions have the obligation to restrict flavored and menthol product sales to protect vulnerable populations from tobacco-related harms. The considerable expenditure of financial resources, political will, and time dedicated to policy adoption and implementation argue for evaluation studies designed to maximize the quality of evidence. This review offers generalizable insights into evaluation findings that can inform efforts to enhance tobacco control policy implementation and impact in the US and globally.

OBJECTIVE: To determine whether awareness of emerging vaping-attributable health conditions influences vaping-related risk perceptions and behaviours among young people. DESIGN: Respondents aged 15-24 years (n=3536) were drawn from a repeated cross-sectional online panel survey (222 participants/week) during an e-cigarette/vaping-associated lung injury (EVALI) outbreak in the USA (September 2019-January 2020). Logistic regression models tested for associations between EVALI awareness and perceived lung injury risk and product harm, stratified by e-cigarette/vape use and controlling for awareness of other e-cigarette/vaping news stories, demographic characteristics and outbreak week. Other models measured the association between perceived risk of lung injury and intentions to use (non-users) or intentions to quit (current users) e-cigarettes/vape products. Changes in national retail e-cigarette sales data were examined during national EVALI outbreak reporting. RESULTS: EVALI awareness was associated with: perceived risk of lung injury (current users OR 1.59, p=0.004; non-users OR 2.11, p<0.001); belief that e-cigarettes/vapes contain dangerous chemicals (current users OR 1.47, p=0.017; non-users OR 1.88, p<0.001) and belief that e-cigarettes/vapes are harmful (current users OR 1.66, p=0.002; non-users OR 1.67, p<0.001). Perceived risk of lung injury from e-cigarette/vape use was associated with intentions to own e-cigarette/vape products (ever-users OR 0.25, p<0.001; never-users OR 0.61, p=0.004) and intentions to quit among current users (OR 2.02, p=0.002). Declines in e-cigarette sales were observed following news of the EVALI outbreak. CONCLUSIONS: News of vaping-attributable health conditions may prevent e-cigarette/vape use and encourage cessation among young people. Tobacco control campaigns should address uncertain health effects of e-cigarettes or vape products and align with risk communication by public health agencies during outbreaks.

INTRODUCTION: Nicotine pouches are gaining popularity, yet their marketing is understudied. METHODS: Using Numerator advertising data from January 2019 to September 2021 regarding three popular brands of nicotine pouch in the USA-Zyn (by Swedish Match, introduced in the USA in July 2016), On! (Altria, August 2016) and Velo (RJ Reynolds, July 2019)-we examined (1) general advertising characteristics (eg, media type, year); (2) ad content (ie, headlines and imagery themes); (3) prominent media channels (ie, specific websites, magazines, etc); and (4) ad expenditures. RESULTS: There were 286 unique ads (Zyn: 44.4%; On!: 2.8%; Velo: 52.8%), 119 143 occurrences (Zyn: 3.5%; On!: 0.5%; Velo: 96.0%) and $24 774 650 total expenditures (Zyn: 4.7%; On!: 0.6%; Velo: 94.7%). The greatest proportion of ad occurrences and expenditures were accounted for by radio (75.9% and 28.2%, respectively) and television (16.2% and 56.5%), followed by mobile (0.5% and 7.2%) and online display (6.7% and 3.6%). Across ad occurrences and expenditures, prominent headline themes included 'freedom' (26.0% and 17.1%, respectively), 'brand' (9.6% and 18.6%) and 'flavour' (16.4% and 7.6%); images mainly featured the product alone (61.4% and 56.1%), text (16.2% and 24.6%) or men (8.7% and 8.6%); and prominent channel themes were entertainment (34.7% and 37.3%), news/weather (14.3% and 21.7%), business/finance (12.9% and 9.0%) and sports (9.5% and 1.0%). Zyn and On! prioritised online display and print; Velo prioritised radio and television. Zyn's and Velo's headlines focused on 'freedom', with Zyn also emphasising 'brand' and Velo 'innovation'; On!'s headlines emphasised 'flavour'. CONCLUSIONS: Regulatory efforts must be informed by surveillance of nicotine pouch marketing and impacts on consumer subgroups (eg, young people).
RESUMO
OBJECTIVES: This umbrella review aims to summarise the evidence about electronic nicotine delivery systems' (ENDS) risk and safety health profile to inform ENDS health communication strategies. DATA SOURCES AND STUDY SELECTION: Six databases were searched for systematic reviews presenting evidence on ENDS-related health effects. Ninety reviews divided into five categories were included: toxicity=20, health effects=40, role in smoking cessation=24, role in transition to combustible cigarettes (CCs)=13 and industry marketing claims=4. DATA EXTRACTION: Findings were synthesised in narrative summaries. Meta-analyses were conducted by study type when appropriate. Quality assessment was conducted using the Measurement Tool to Assess Systematic Reviews. The Institute of Medicine's Levels of Evidence Framework was used to classify the evidence into high-level, moderate, limited-suggestive and limited-not-conclusive. DATA SYNTHESIS: We found high-level evidence that ENDS exposes users to toxic substances; increases the risk of respiratory disease; leads to nicotine dependence; causes serious injuries due to explosion or poisoning; increases smoking cessation in clinical trials but not in observational studies; increases CC initiation; and exposure to ENDS marketing increases its use/intention to use. Evidence was moderate for ENDS association with mental health and substance use, limited-suggestive for cardiovascular, and limited-not-conclusive for cancer, ear, ocular and oral diseases, and pregnancy outcomes. CONCLUSIONS: As evidence is accumulating, ENDS communication can focus on high-level evidence on ENDS association with toxicity, nicotine addiction, respiratory disease, ENDS-specific harm (explosion, poisoning) and anti-ENDS industry sentiment. Direct comparison between the harm of CCs and ENDS should be avoided. PROSPERO REGISTRATION NUMBER: CRD42021241630.
RESUMO
Mass media campaigns are an effective population-level intervention for preventing tobacco use. However, little evidence exists for whether these campaigns similarly influence demographic subgroups. This study examined the effects of the truth® campaign to reduce tobacco use among demographic subgroups. We used data from a national, continuous, cross-sectional tracking survey of 15-24-year-olds (n = 32 331). We used a measure of weekly aggregated campaign exposure to assess whether cigarette smoking intentions and current cigarette use varied by race/ethnicity, financial situation and population density subgroups, controlling for factors known to be associated with tobacco use. Examining estimates across subgroup categories in light of the overall model estimates revealed that the effects of week-level campaign exposure on cigarette smoking intentions and current cigarette use were similar across subgroups. Wald tests of equality across estimates in each subgroup suggested that the estimates did not differ from one another in any given instance. The truth campaign does not differ significantly in its capacity to prompt declines in tobacco use across a broad spectrum of US youth and young adults. Mass media tobacco prevention campaigns can be an effective and critical component of a comprehensive tobacco control program, particularly with respect to reducing tobacco-related disparities among demographic subgroups.

Objective: To examine use and frequency patterns across e-cigarettes, cigarettes, and little cigars, cigarillos, and cigars (LCCs) over time. Methods: Data were obtained from the Truth Longitudinal Cohort (TLC), a nationally representative longitudinal cohort of youth and young adults. Latent class analysis was conducted to classify participants (n = 5274) into subgroups based upon frequency of use of cigarettes, e-cigarettes, and little cigars, cigarillos, and cigars (LCCs) in the past 30 days. Latent transition analysis was used to estimate the probability of use pattern transitions across 23 months (February 2018 to December 2019), adjusted for the effects of gender, race/ethnicity, financial situation, sensation seeking, parent education, and household smoking. Findings: Findings reveal four groups of tobacco product users: (1) frequent to daily cigarette users (9%), (2) frequent to daily cigarette and LCC users (3%), (3) frequent to daily e-cigarette users (10%), and (4) former or noncurrent tobacco users (78%). Although most respondents (69-94%) retained their initial user patterns during the observation period, results also indicate shifts between user groups. Notably, 14% of frequent to daily cigarette and LCC users transitioned to frequent to daily cigarette use, while 6% of frequent to daily cigarette and LCC users, 9% of frequent to daily cigarette users, and 4% of former or noncurrent tobacco users transitioned to frequent to daily e-cigarette use. Conclusion: Although most frequent to daily tobacco users stay with their primary product, there are transitions between frequent to daily cigarette, e-cigarette, and LCC use. Transition patterns may influence risk for nicotine addiction among youth and young adults. Thus, policies focused on preventing and reducing all tobacco use are needed to curb the risk of nicotine addiction among youth and young adults.

Objective: The objective of this study is to examine the relationships between e-cigarette flavors, nicotine concentration, and their interaction on measures of nicotine dependence.Methods: Survey data are drawn from a cross-sectional convenience sample of past 30-day e-cigarette users aged 15 to 24 years (N = 2037) collected between October 2020 and November 2020. Participants were asked to provide information about the e-cigarette products they used most regularly. Only those with available information on flavors (fruit, mint, menthol/ice, and tobacco), nicotine concentration (0-2.9%, 3-4.9%, and 5% or greater), and time to first vape after waking (within 30 minutes, greater than 30 minutes) were included in analyses (N = 1430). Generalized linear regression models were used with log link and binary distribution to assess the relationship between flavors, nicotine concentration, and nicotine dependence. Effect modification by nicotine concentration was assessed using an interaction term for flavors by nicotine concentration. Models were adjusted for age, race/ethnicity, gender, and financial situation.Findings: Fruit, mint, and menthol flavor user groups had a very similar dose-response relationship between nicotine concentration and prevalence of vaping within 30 minutes. These groups showed that the prevalence of vaping within 30 minutes gradually increased as nicotine concentration increased. Meanwhile, tobacco flavor user groups demonstrated a decrease in prevalence of vaping within 30 minutes, as nicotine concentration increased.Conclusion: Results highlight the need for understanding how e-cigarette product characteristics like flavors and nicotine concentration can facilitate nicotine dependence to e-cigarettes. Findings suggest that comprehensive e-cigarette product regulation of all flavors and reducing nicotine concentration will help to reduce the risk for nicotine dependence among young people.

Objectives. To determine whether the COVID-19 pandemic affected e-cigarette use among young people in the United States.Methods. Data came from a weekly cross-sectional online survey of youths and young adults (aged 15-24 years). Logistic regression analyses measured odds of past-30-day e-cigarette use (n = 5752) following widespread stay-at-home directives (March 14-June 29, 2020), compared with the preâCOVID-19 period (January 1-March 13, 2020). Logistic regression among a subsample of current e-cigarette users (n = 779) examined factors associated with reduced use following stay-at-home orders.Results. Odds of current e-cigarette use were significantly lower during the COVID-19 pandemic compared with the preâCOVID-19 period among youths aged 15 to 17 years (odds ratio [OR] = 0.72; 95% confidence interval [CI] = 0.54, 0.96) and young adults aged 18 to 20 years (OR = 0.65; 95% CI = 0.52, 0.81). E-cigarette users with reduced access to retail environments had higher odds of reporting reduced e-cigarette use (OR = 1.51; 95% CI = 1.07, 2.14).Conclusions. COVID-19 stay-at-home directives present barriers to e-cigarette access and are associated with a decline in e-cigarette use among young people.Public Health Implications. Findings support the urgent implementation of interventions that reduce underage access to e-cigarettes to accelerate a downward trajectory of youth and young adult e-cigarette use.

In 2020, almost 20% of high school students reported current e-cigarette use. Mass media tobacco prevention campaigns are effective for preventing tobacco use among youth and young adults but selecting messages that will have maximum impact on the target audience is a significant challenge for campaign developers. This study describes the method for identification of potential messaging targets for a national anti-vape mass media campaign using criteria proposed by Hornik and Woolf in their health communication framework. A national sample of 15- to 24-year-olds (N = 1564) was recruited via an online panel in May 2020. Participants endorsed a series of vape-related attitudinal items. Items were considered potential message targets if they distinguished between the four vape use groups (current users, ever users, susceptible never-users, and non-susceptible never-users) and if less than 70% of respondents endorsed the anti-vape item response. The resulting items targeted five potential message themes, each forming a scale measured with three to four individual items. Message themes included social acceptability of vaping, anti-vape industry sentiment, independence from vaping, non-vaping identity, and perceived risk of harm. Findings were used to inform the development of truth® campaign messaging focused on reducing the prevalence of e-cigarette use among youth and young adults.
