E-Cigarette Use Among Youths and Young Adults During the COVID-19 Pandemic: United States, 2020

Factors associated with intentions to quit vaping and quit attempts among Adolescents: A structural equation modeling approach

OBJECTIVES

Previous youth tobacco research has identified multiple factors relating to intentions to quit vaping and quit attempts among current e-cigarette users in adolescents. The pathways in the complex associations with vaping cessation behaviors remain unclear.

METHODS

Using data from the 2022 National Youth Tobacco Survey (NYTS) (grades 6-12), structural equation models (SEMs) are developed to examine the associations of social environment, vaping risk perceptions, e-cigarette marketing, vaping characteristics, and demographics with two outcome measures - intentions to quit vaping and past year quit attempts among current e-cigarette users.

RESULTS

The national sample of current e-cigarette users (n = 2,701) consisted of 52.7 % females, 47.0 % non-Hispanic Whites, 80.1 % high school students, and 56.2 % heterosexual individuals. Among them, 70.2 % reported intentions to quit vaping and 66.3 % reported past year quit attempts. The protective factor for quit intentions was vaping risk perceptions (p < 0.001). Risk factors included e-cigarette marketing (p = 0.04), dual use of e-cigarettes and other tobacco products (p = 0.003), vaping due to feeling anxious or stressed (p = 0.01), vaping for nicotine buzz (p = 0.002), nicotine dependence (p = 0.02), identifying as Gay or Lesbian (p < 0.001), bisexual (p = 0.03), or Hispanic (p = 0.04). Similar associations were observed with quit attempts except that e-cigarette marketing, vaping due to feeling anxious or stressed, vaping dependence, and identifying as Hispanic were not significant. Besides, high vaping frequency (p < 0.001), grade level (p < 0.001) and not sure about sexual orientation (p = 0.01) were also negatively associated with quit attempts.

CONCLUSIONS

This study provided insights into factors influencing vaping cessation outcomes among adolescent current e-cigarette users. Developing tailored vaping cessation programs based on these findings could enhance quit success.

Comparison of smoking traditional, heat not burn and electronic cigarettes on salivary cytokine, chemokine and growth factor profile in healthy young adults-pilot study

Objective: Smoking is the cause of numerous oral pathologies. The aim of the study was to evaluate the effect of smoking traditional cigarettes, e-cigarettes, and heat-not-burn products on the content of salivary cytokines, chemokines, and growth factors in healthy young adults. Design: Three groups of twenty-five smokers each as well as a control group matched in terms of age, gender, and oral status were enrolled in the study. In unstimulated saliva collected from study groups and participants from the control group, the concentrations of cytokines, chemokines, and growth factors were assessed by Bio-Plex® Multiplex System. Results: We demonstrated that smoking traditional cigarettes is responsible for increasing the level of IFN-γ compared to non-smokers and new smoking devices users in unstimulated saliva in the initial period of addiction. Furthermore, e-cigarettes and heat-not-burn products appear to have a similar mechanism of affecting the immune response system of unstimulated saliva, leading to inhibition of the local inflammatory response in the oral cavity. Conclusion: Smoking traditional cigarettes as well as e-cigarettes and heat-not-burn products is responsible for changes of the local immune response in saliva. Further research is necessary to fill the gap in knowledge on the effect of new smoking devices on the oral cavity immune system.

Engagement, Mental Health, and Substance Use Under In-Person or Remote School Instruction During the COVID-19 Pandemic

BACKGROUND

Adolescents' school engagement, mental health, and substance use have been major concerns during the COVID-19 pandemic, particularly given disruptions to school instruction. We examined how the instructional setting was associated with academic and health-related outcomes within an adolescent cohort followed during the pandemic.

METHODS

During 3 semi-annual follow-up surveys, adolescents (N = 1066 students; 2242 observations) from 8 California high schools responded to items measuring academic self-efficacy, school connectedness, internalizing and externalizing problems, and use of substances. Separate generalized estimating equation models predicted outcomes based on the instructional setting.

RESULTS

Relative to in-person instruction, students in remote instruction reported lower academic self-efficacy (Beta: -0.11; 95% confidence interval [CI]: -0.22, -0.01) and school connectedness (Beta: -0.37; 95% CI: -0.48, -0.25), greater odds of past 30-day internalizing problems (AOR: 1.46; 95% CI: 1.09, 1.95), externalizing problems (AOR: 1.36; 95% CI: 1.02, 1.82), and cigarette, cigar, smokeless tobacco, or hookah use (AOR: 2.50; 95% CI: 1.06, 5.91), but lower odds of past 30-day e-cigarette use (AOR: 0.50; 95% CI: 0.30, 0.86).

CONCLUSIONS

Multiple adverse outcomes related to school engagement, mental health, and substance use were associated with remote instruction. To reduce such impacts under future emergencies, schools should rely sparingly on remote instruction and provide appropriate supportive resources.

Bidirectional relationships between nicotine vaping and maladaptive eating behaviors among young adults

Background

Past research indicates that young adult cigarette smokers are at risk of engaging in maladaptive eating behaviors (MEBs); however, whether this relationship extends to nicotine vaping is unclear. The current study assessed bidirectional associations between four types of MEBs and nicotine vaping among young adults.

Methods

1,303 young adults (20.5 ± 2.3 years; 63 % female) from a public, urban university were recruited and completed online surveys at six-month intervals from spring 2021 (W1) to spring 2023 (W5). Past 30-day nicotine vaping and four types of MEBs (susceptibility to external cues, emotional eating, routine restraint, and compensatory restraint) were evaluated.

Results

Longitudinal cross-lagged models examined the bidirectional relationships between past 30-day nicotine vaping and each type of MEB across five waves. Nicotine vaping predicted both susceptibility to external cues (β = 0.10, p <.05; Wave 2 to 3) and emotional eating (β = 0.08, p <.05; Wave 1 to 2). A significant cross-lag regression (Wave 4 to 5) showed nicotine vaping predicted to routine restraint (β = 0.08, p <.05), and routine restraint predicted to nicotine vaping (β = 0.12, p <.05).

Conclusions

Results indicated that nicotine vaping predicted MEBs; however, the type of MEB differed across waves, which may have been due to the COVID-19 pandemic context. Nicotine vaping predicted to MEBs reflecting vulnerability to the external environment and emotion regulation during a period of heightened restrictions, whereas later when pandemic restrictions had ceased nicotine vaping predicted only to routine restraint. Integrating research and practice on nicotine vaping and MEBs may inform public health efforts to decrease co-occurring health-risks in young adulthood.

Factors Associated With the Changes in Smoking and Electronic cigarette use in Adolescents During the COVID-19 Pandemic: A Longitudinal Analysis

PURPOSE

Explore the factors associated with the changes in smoking and electronic cigarette (e-cigarette) use and susceptibility among adolescents during the COVID-19 pandemic.

METHODS

We surveyed a cohort of students (7th-12th grade) from private schools in Guatemala. Baseline (May-September 2019) was conducted in-person and follow-up (June-November 2020) online during the lockdown. Separate Generalized Estimating Equations logistic models regressed current smoking (n = 3,729), current e-cigarette use (n = 3,729), smoking susceptibility among never-smokers (n = 2,596), and susceptibility to e-cigarette use among never-users (n = 1,597) on online ad exposure, visiting stores, social network smoking/e-cigarette use, substance use (alcohol, marihuana, and cigarette or e-cigarette), perceived harm of using cigarettes/e-cigarettes, sociodemographic characteristics, and survey wave. Interactions were assessed between time and ad exposures, friends smoking and e-cigarette use.

RESULTS

Frequency of store visits, exposure to online ads, and the use of cigarette and e-cigarette lowered at follow-up. Online e-cigarette ads, having family and friends who smoke, and current e-cigarette use increased the likelihood of being a current smoker. Frequent exposure to online e-cigarette ads, having family who use e-cigarettes, and being a current smoker were associated with higher likelihood of current e-cigarette use. Exposure to either online ads or having friends that smoke or use e-cigarettes, increased susceptibility to using either product. Interaction results showed that high exposure to online e-cigarette ads overtime increased the susceptibility to use e-cigarettes.

DISCUSSION

Exposure to online ads and friends and family cigarette and e-cigarette use increased adolescent consumption and susceptibility during the pandemic.

E-cigarette Use and Severe Coronavirus Disease 2019 (COVID-19) Outcomes: A Meta-Analysis

E-cigarettes have been known to cause varied poor health outcomes prior to coronavirus disease 2019 (COVID-19), but after the impact of COVID-19, evidence came out that was, in some instances, not as expected regarding the severity of COVID-19 among e-cigarette users (vapers). A meta-analysis was performed on the available evidence to comprehensively find the effect of COVID-19 on existing or past e-cigarette users (vapers). The Meta-analysis of Observational Studies in Epidemiology (MOOSE) guidelines were used to perform this meta-analysis. PubMed was searched for observational studies that described outcomes after COVID-19 positivity from December 1, 2019, to December 2023. Medical Subject Headings (MeSH) keywords were used for searching the relevant studies highlighting the relationship between COVID-19 and e-cigarette users. Calculations for pooled prevalence, 95% confidence interval (95% CI), weights for current e-cigarette users and vapers, and outcomes (events) were made. To analyze the data, Review Manager V.5.4 was used. The I² statistic was used to assess statistical heterogeneity. The I² statistic of >50% was considered significant heterogeneity. The "leave-one-out" method was used for sensitivity analysis. Out of 3231 studies, four studies reported data on vaping and non-vaping status and composite outcomes, resulting in a sample size of 653 COVID-19-positive cases. The pooled prevalence of being COVID-19 positive, having symptoms, or visiting an emergency room was 7.78% (653/8392). COVID-19 patients with current vaping status had decreased odds of poor outcomes compared to non-smokers, with a pooled odds ratio (OR) of 0.09 (95% CI 0.00-2.42; p>0.05) with heterogeneity between studies (I²=99%, p=0.15). Because of difficulties related to data collection and other factors, this meta-analysis was unable to conclusively establish the correlation between e-cigarette usage and severe COVID-19 outcomes such as hospitalization, admission to the intensive care unit, and fatality. Additional research using more detailed data is necessary to fully understand this correlation.

E-cigarette use or dual use of E-cigarette and combustible cigarette and mental health and cognitive impairment: Findings from the National Health Interview Survey, 2020-2021

BACKGROUND

Studies on the association between e-cigarette use and mental health are mostly among adolescents and young adults, leaving limited evidence of this association among general US adults. Besides, few studies have examined how e-cigarette use or dual use of e-cigarette and combustible cigarette is related to cognitive function.

METHODS

Cross-sectional data of 56,734 adults from the 2020-2021 National Health Interview Survey were analyzed. Weighted multivariable logistic regression models were applied to examine the independent association between e-cigarette use or dual use and anxiety symptoms, depression symptoms, serious psychological distress (SPD), and cognitive impairment.

RESULTS

Compared with never e-cigarette users, current e-cigarette users had 2.10-fold (95 % CI: 1.84, 2.39), 2.53-fold (95 % CI: 2.13, 3.00), 2.02-fold (95 % CI: 1.47, 2.76), and 2.00-fold (95 % CI: 1.47, 2.72) higher odds of reporting anxiety symptoms, depression symptoms, SPD, and cognitive impairment, respectively. Former e-cigarette use was also associated with all three mental conditions and cognitive impairment (AOR ranged from 1.38 to 2.53, all P < 0.01). Dual users were more likely to report all three mental conditions and cognitive impairment than those who never used combustible cigarette and e-cigarette (AOR ranged from 1.89 to 2.83, all P < 0.01). Dual users also had a greater likelihood of having anxiety or depression symptoms than exclusive combustible cigarette users (AOR ranged from 1.46 to 1.47, all P < 0.01).

CONCLUSIONS

E-cigarette use or dual use is associated with poor mental health and cognitive impairment among US adults. Regulations on e-cigarette use are needed to prevent mental illness and improve cognitive function.

Changes in substance use among adolescents before and during the COVID-19 pandemic in Guatemala

Objectives

Due to the COVID-19 pandemic, on March 16th, schools had to be closed in Guatemala and went to online teaching. We sought to analyze the change in substance use among high school students in Guatemala associated with the lockdown.

Methods

Data from two surveys (2019, n=2096, and 2020, n=1606) of a student cohort in private high schools in Guatemala City was used. Logistic models for past 30-day cigarette, e-cigarette, marijuana, and alcohol (including binge drinking) were used, regressing these on survey wave, while adjusting for sex, scholastic performance, high school year of student, parental education, substance use, and household member tobacco use.

Results

Prevalence declined for smoking (10% to 3%, p<0.001), e-cigarette (31% to 14%, p<0.001), marijuana (4.3% to 1.9%, p<0.001), and alcohol use (47% to 38.5%, p<0.001), and binge drinking (24% to 13%, p<0.001). Adjusted models showed wave 2 associated with lower odds of using cigarettes (AOR=0.44, 95%CI=0.32-0.62), e-cigarettes (AOR=0.41, 95% CI=0.35-0.49, p<0.001), and binge drinking (AOR=0.73, 95%CI=0.59-0.89; p=0.002).

Conclusion

Among Guatemalan adolescents, COVID-19 restrictions were associated with a significant decrease in smoking, e-cigarette use, and binge drinking.

Emerging Adults' Experiences with E-Cigarette Cessation

Background: The use of electronic nicotine delivery systems (ENDS) is one of the most common substance use behaviors in college students, yet most individuals show some interest in quitting. The current study added to the limited literature on ENDS cessation by examining readiness to quit and the use and perceived efficacy of ENDS cessation methods in a heterogeneous sample of college students. Methods: Students 18-24 years in Psychology courses (N = 1563; 73% female) from six US universities completed an online survey between September 2021-April 2022. Results: Nearly half the sample (n = 738, 47%) reported lifetime ENDS use and nearly half of lifetime users (n = 356, 48%) reported a quit attempt. Most ENDS users reported some readiness to quit (n = 251, 67%). Quitting "cold turkey", using willpower, and replacing ENDS use with another activity were endorsed most frequently; strategies were perceived as more helpful if students had direct experience with them. Social support (e.g., counseling, groups, family/friend support) and nicotine replacement products were perceived as effective but were utilized infrequently. Digital tools (i.e., apps, text messaging) were perceived to be least helpful and were utilized infrequently. Conclusion: Most college students who use ENDS are interested in quitting and have relied on unassisted methods for cessation. Our data suggest a significant opportunity for college personnel and public health officials to further enhance awareness and uptake of ENDS cessation resources for this demographic. Digital tools that integrate social support may be especially effective given their low cost, demonstrated efficacy, and alignment with students' preferences for social support.

Patterns of Daily Cigarette and E-cigarette Use among United States Youth and Young Adults: Insights from the Truth Longitudinal Cohort between 2018 and 2019

Purpose

Temporal patterns of daily tobacco product use among ever users from the Truth Longitudinal Cohort (TLC) between 2018 and 2019 were explored.

Methods

The sample (N = 5274) includes individuals (15-36 years), residing in the United States, who had ever used any tobacco product at Wave 7 (February - May 2018) and provided tobacco use information at Wave 9 (September - December 2019).

Results

There was a nonsignificant 1.1 percentage point increase in daily tobacco use (on at least 25 of the past 30 days), from 14.6% (95% CI: 12.8, 16.6) to 15.7% (95% CI: 13.8, 17.7). Tobacco product use remained stable over time, as 65.3% (95% CI: 56.4, 73.3) of daily cigarette smokers, 57.0% (95% CI: 43.6, 69.4) of daily e-cigarette vapers, and 8.5% (95% CI: 2.0, 29.3) of daily dual users stayed with their primary tobacco product. There was also some evidence of switching, as 7.5% (95% CI: 3.7, 14.8) of daily cigarette smokers became daily e-cigarette vapers and 2.3% (95% CI: 0.7, 6.8) of daily e-cigarette vapers became daily cigarette smokers.

Discussion

Although most daily tobacco users were likely to continue using their primary product, some daily users transitioned to daily use of other products - suggesting that policies and public education focused on reducing overall nicotine use are essential for addressing the nicotine epidemic among young people.

Pathways to Quitting E-cigarettes Among Youth and Young Adults: Evidence From the truth® Campaign

PURPOSE

This study examines the pathways through which e-cigarette users' awareness of the truth® campaign influences e-cigarette use frequency over time.

DESIGN AND SETTING

Data included four waves (2020-2023) of the Truth Longitudinal Cohort, a probability-based, nationally representative survey.

PARTICIPANTS

The analytic sample was 15-24-year-olds who reported current e-cigarette use at baseline (N = 718). Wave-by-wave retention rates were 64% to 69%.

MEASURES

Respondents' cumulative awareness of truth® ads was calculated (Waves 1-2). Strength of agreement with campaign-targeted attitudes was measured on five-point scales (Wave 2). The outcome was change in the 4-level frequency of e-cigarette use (Waves 2-4).

ANALYSIS

Latent growth structural equation modeling examined the pathway from cumulative ad awareness to the frequency of e-cigarette use via campaign-targeted attitudes.

RESULTS

Model fit estimates identified a three-step pathway by which awareness of the campaign reduced e-cigarette use. Ad awareness was significantly associated with stronger campaign-targeted attitudes: perceived risk (β = .20, P < .0001); anti-vape industry (β = .13, P = .003); independence from addiction (β = .13, P = .004); and affinity with groups that reject vaping (β = .18, P < .0001). Each attitude was significantly associated with stronger perceived norms against e-cigarette use (respectively: β = .25, P < .0001; β = .15, P < .0001; β = .12, P = .018; β = .27, P < .0001). Perceived norms against e-cigarette use had a significant negative relationship with growth in e-cigarette use frequency over time (β = -.23, P < .0001).

CONCLUSION

Greater truth® anti-vaping ad awareness strengthens campaign-targeted attitudes among current users, increasing perceived norms against e-cigarette use and reducing use over time.

Assessment of prevalence, predictors, reasons and regulations of substance smoking among children in Ghana

BACKGROUND

In Ghana, it is against the law for children to smoke. Nevertheless, a portion of children in the country do smoke. However, there is a paucity of research on young smokers in Ghana and other sub-Saharan African nations. This study, therefore, investigated the prevalence of smoking, the kinds of substances children smoke, predictors of smoking, reasons for and factors that lead children to smoke, and regulation of smoking among children in Ghana.

METHODS

In total, 5024 children aged 8-17 were studied using a cross-sectional convergent parallel mixed method. Descriptive statistics, Person's Chi-square test, Fisher Exact test, and binary logistic regression were used to analyse the quantitative data. In contrast, thematic analysis was used to analyse the qualitative data.

RESULTS

The results showed that 3.2% of children had ever smoked. Male children smoked more often than female children. The prevalence of cigarette, marijuana, and shisha smoking was 78.3%, 18%, and 3.7%, respectively. While more male children than female children smoked cigarettes and marijuana, more female children than male children used shisha. Children mainly smoked for fun and due to group culture. In addition, children were influenced by friends; parents, family members, and neighbours who smoke; curiosity; and advertisements and videos to initiate smoking. Despite the availability of regulations and laws regulating tobacco products in public places, tobacco advertisement, promotion, and sale to persons under 18, children are still smoking.

CONCLUSIONS

Children who have ever engaged in smoking reported using cigarettes, marijuana, and shisha. Policymakers urgently need to strategise and strengthen their policies, programmes, and interventions to address smoking among children.

Trends in E-Cigarette and Tobacco Cigarette Purchasing Behaviors by Youth in the United States, Canada, and England, 2017-2022

Objectives: This paper describes trends in youth e-cigarette (EC) and tobacco cigarette (TC) purchasing behaviors in Canada, England, and the United States (US) in relationship to changing minimum legal age (MLA) laws. Methods: Data are from eight cross-sectional online surveys among national samples of 16- to 19-year-olds in Canada, England, and the US conducted from 2017 to 2022 (N = 104,467). Average wave percentage change in EC and TC purchasing prevalence and purchase locations were estimated using Joinpoint regressions. Results: EC purchasing increased between 2017 and 2022, although the pattern of change differed by country. EC purchasing plateaued in 2019 for the US and in 2020 for Canada, while increasing through 2022 for England. TC purchasing declined sharply in the US, with purchasing from traditional retail locations declining, while purchasing from social sources increased. Vape shops were the most common location for EC purchasing, although declining in England and the US. Conclusion: Trends in EC and TC purchasing trends in the US are consistent with the expected impact of the federal MLA law increasing the legal age to 21 years in December 2019.

COVID-19 and tobacco products use among US adults, 2021 National Health Interview Survey

Background

Smoking and vaping are linked to lung inflammation and lowered immune response.

Objective

Examine the prevalence of coronavirus disease 2019 (COVID-19) cases, testing, symptoms, and vaccine uptake, and associations with tobacco product use.

Methods

Data came from the 2021 National Health Interview Survey. The 2021 Sample Adult component included 29,482 participants with a response rate of 50.9%. We investigated COVID-19-related outcomes by tobacco product use status and reported national estimates. Multivariable regression models were performed accounting for demographics (e.g., age, sex, poverty level), serious psychological distress, disability, and chronic health conditions.

Results

In our regression analyses, odds of self-reported COVID-19 infection were significantly lower for combustible tobacco product users (vs. nonusers; adjusted odds ratio [AOR = 0.73; 95% confidence interval [CI] = 0.62-0.85]). Combustible tobacco users also were less likely to report ever testing for COVID-19 (AOR = 0.88; 95% CI = 0.79-0.98), ever testing positive for COVID-19 (AOR = 0.66; 95% CI = 0.56-0.77), and ever receiving COVID-19 vaccine (AOR = 0.58; 95% CI = 0.51-0.66) compared with their nonuser peers. Compared to nonusers, users of any type of tobacco who contracted COVID-19 had higher odds of losing smell (AOR = 1.36; 95%CI = 1.04-1.77), which was more pronounced among exclusive e-cigarette users. The odds of receiving vaccine were lower for all current exclusive tobacco product users compared to nonusers (AORs = 0.40 to 0.70).

Conclusions

Continued monitoring of tobacco product use and its association with respiratory diseases such as COVID-19 is crucial to inform public health policies and programs. In addition, efforts to promote vaccination, especially among tobacco product users, are warranted.

Changes in E-Cigarette Use Among U.S. Adults, 2019-2021

INTRODUCTION

E-cigarette use increased between 2014 and 2018 among younger U.S. adults who had never smoked combustible cigarettes, potentially increasing nicotine addiction risk and progression to combustible tobacco products. It is unknown how prevalence changed after the E-cigarette, or vaping, product use-associated lung injury epidemic (late 2019) and COVID-19 pandemic (March 2020) by age group and combustible cigarette smoking status.

METHODS

Data from cross-sectional, nationally representative National Health Interview Surveys in 2019, 2020, and 2021 (analyzed in 2022) were used to estimate current E-cigarette use prevalence, adjusted prevalence difference between survey years, and population counts, by age group (younger, 18-29 years, n=11,700; middle age, 30-44 years, n=21,300, 45-59 years, n=21,308; older, ≥60 years, n=36,224) and cigarette smoking status (current, former, and never).

RESULTS

E-cigarette use prevalence increased among younger adults between 2019 and 2021 (8.8%-10.2%, adjusted prevalence difference=1.7% points, 95% CI=0.1, 3.3), primarily owing to an increase among those who never smoked cigarettes (4.9%-6.4%, adjusted prevalence difference=1.7% points, 95% CI=0.3, 3.1). People who never smoked cigarettes constituted 53% (2.68 million) of younger adults who used E-cigarettes in 2021, increasing by 0.71 million from 2019. Conversely, among middle age and older adults, the prevalence was similar in 2019 and 2021 irrespective of cigarette smoking status, and those who formerly smoked cigarettes constituted the largest proportion of people who used E-cigarettes in 2021 (age 30-44 years: 51.8%, 1.8 million; age 45-59 years: 51.6%, 0.85 million; age ≥60 years: 47.5%, 0.45 million).

CONCLUSIONS

Efforts must address the rise in E-cigarette use among younger adults who never smoked cigarettes. At the same time, assistance is needed to help those who switched to E-cigarettes to stop smoking to transition to non-use of all products.

The moderating role of mental health on the association between COVID-related stress, isolation, and economic hardship and using substances to cope

Since young adulthood is a vulnerable period for adverse mental health experiences and high-risk substance use, it is critical to understand the impact of the COVID-19 pandemic on young adult mental health and substance use behaviors. Therefore, we determined whether the relationship between COVID-related stressors and using substances to cope with COVID-related social distancing and isolation was moderated by depression and anxiety among young adults. Data were from the Monitoring the Future (MTF) Vaping Supplement (total N = 1244). Logistic regressions assessed the relations between COVID-related stressors, depression, anxiety, demographic characteristics, and interactions between depression/anxiety and COVID-related stressors with vaping more, drinking more, and using marijuana to cope with COVID-related social distancing and isolation. Greater COVID-related stress due to social distancing was associated with vaping more to cope among those with more depression symptoms and drinking more to cope among those with more symptoms of anxiety. Similarly, COVID-related economic hardships were associated with using marijuana to cope among those with more symptoms of depression. However, feeling less COVID-related isolation and social distancing stress was linked to vaping and drinking more to cope, respectively, among those with more symptoms of depression. These findings suggest that the most vulnerable young adults are seeking substances to cope with the pandemic, while potentially experiencing co-occurring depression and anxiety along with COVID-related stressors. Therefore, intervention programs to support young adults who are struggling with their mental health in the aftermath of the pandemic as they transition into adulthood are critical.

It's addiction at this Point": A qualitative examination of youth E-cigarette use trajectory in the United States

E-cigarettes (electronic cigarettes) have been the most used tobacco product among US youth since 2014, reaching a plateau during the COVID-19 pandemic. Youth e-cigarette use is associated with negative health consequences such as impaired cognitive functioning. For many, the COVID-19 pandemic altered social interactions, harm perceptions, and product availability. This changed the frequency and locations in which youth use e-cigarettes. To better understand youth e-cigarette use, we need more information on factors that can alter e-cigarette use, specifically, how the pandemic changed e-cigarette use among youth. In 2020-2021, we conducted online, individual interviews with 19 youth (aged 13-17) e-cigarette users living in the US to explore how COVID-19 impacted their e-cigarette use. Youth described a progression of e-cigarette use from initial experimentation, regular social use, and ultimately to nicotine addiction demonstrated by individual use in isolation. Many youth initiated e-cigarette use due to influences by friends or family members. Youth discussed progression to social use, with social interactions as an important reason for use and an avenue for expanding one's knowledge of e-cigarettes. After a period of time, youth began to recognize that the social interactions mattered less, suggesting to them that they had become addicted. This realization became more apparent during COVID-19, which changed how youth used e-cigarettes, especially around where use was occurring, health concerns, and use behavior and frequency. In our interviews, youth trajectory began with an initiation with family and friends, progressed to social use, and eventually developed to addiction, at which point social use was no longer the primary motivation for e-cigarette use. Understanding the trajectory of e-cigarette use will allow for effective interventions that reduce harm to youth from e-cigarette use.

Initial impacts of the COVID-19 pandemic on tobacco use among college students in California

Objective: To evaluate the change in tobacco use by college students in California during the COVID-19 pandemic. Participants: Young adults (18-24 years) currently enrolled in a California college or university (N = 212). Methods: Students recruited through social media posts and by student tobacco advocate members completed an online survey of 59 questions in Spring 2021. Results: Almost 80% of current tobacco users reported a change in tobacco use during the pandemic. Most current tobacco users who changed their tobacco use reported an increase in use during the pandemic (43.2%) and 38.7% reported a decrease in use. Conclusion: As a result of COVID-19, many college students changed their tobacco use. As students return to campus and COVID-19 regulations are lifted, this may be an ideal time for prevention and cessation messages, which could include information on health risks associated with tobacco and e-cigarette use, and healthy methods for stress reduction.

Perceptions of and Experiences With Cigarette and E-Cigarette Use Among a Diverse Population of US Latino Adolescents and Young Adults

PURPOSE

To determine potential unique factors influencing cigarette and e-cigarette use in US Latino youth.

APPROACH

We conducted a qualitative study assessing cigarette and e-cigarette perceptions and experiences, including experiences with/perceptions of the products, cultural influences and influences of friends and family.

SETTING

Four online discussion boards, conducted in October 2020.

PARTICIPANTS

92 Latino youth aged 15-21 years living in the US.

METHOD

Data from the discussion groups were coded and analyzed by three trained coders using a thematic analysis approach.

RESULTS

Stress relief emerged as the dominant theme connected with both cigarettes and e-cigarettes. Apart from stress, perceptions of and experiences with the products differed. E-cigarettes were commonly viewed as trendy and cool and participants often reported using them due to curiosity and popularity. Participants commonly compared e-cigarettes to cigarettes, noting benefits of e-cigarettes. Participants also noted more negative short and long-term health effects of cigarette use, and discussed generational differences between the two products.

CONCLUSION

Findings from this study help address a dearth of research examining tobacco use among diverse groups of Latino youth. Findings indicate that despite differences in country of heritage, Latino youth are united by similar opinions about cigarettes and e-cigarettes. Additionally, they share cultural values and experiences which could be leveraged for tobacco control communications that cut across populations of Latino youth.

Associations between depression, stress, and e-cigarette use among OEF/OIF veterans

The COVID-19 pandemic has had profound mental and behavioral health implications for the general U.S. population. However, little is known regarding outcomes for U.S. veterans, who represent a population with high rates of depression, stress, and e-cigarette use. One month prior to the pandemic-related closures (February 2020), 1230 OEF/OIF veterans (ages 18-40) completed an online baseline survey. Six months later, participants completed a follow-up survey (83% retention rate). Hierarchical negative binomial regressions were used to examine the relationship between baseline depression and past 30-day e-cigarette use at follow-up and whether baseline stress moderated this relationship. Veterans who screened positive for depression or who endorsed higher stress levels reported greater e-cigarette use at follow-up. Stress also moderated the relationship between depression and e-cigarette use, such that regardless of stress levels, a positive depression screen was associated with greater rates of later e-cigarette use. However, for those with a negative depression screen, higher stress levels were associated with greater e-cigarette use relative to lower stress levels. Veterans with pre-pandemic depression and stress may be at highest risk for e-cigarette use. Ongoing assessment and treatment for depression and promoting stress management skills for veterans in e-cigarette use prevention and intervention programs may be valuable.

Examining Disparities in Current E-Cigarette Use among U.S. Adults before and after the WHO Declaration of the COVID-19 Pandemic in March 2020

This paper aims to estimate the prevalence of e-cigarette use before and after the COVID-19 pandemic declaration and to delineate disparities in use across subpopulations. Data were derived from the 2020 Health Information National Trends Survey (N = 3865) to conduct weighted multivariable logistic regression and marginal analyses. The overall prevalence of current e-cigarette use increased from 4.79% to 8.63% after the COVID-19 pandemic declaration. Furthermore, non-Hispanic Black people and Hispanic people had lower odds of current e-cigarette use than non-Hispanic White people, but no significant differences were observed between groups before the pandemic. Compared to heterosexual participants, sexual minority (SM) participants had higher odds of current e-cigarette use after the declaration, with insignificant differences before. People who had cardiovascular disease conditions, relative to those without, had higher odds of current e-cigarette use after the declaration, but no group differences were found before the declaration. The marginal analyses showed that before and after the pandemic declaration, SM individuals had a significantly higher probability of using e-cigarettes compared to heterosexual individuals. These findings suggest the importance of adopting a subpopulation approach to understand and develop initiatives to address substance use, such as e-cigarettes, during pandemics and other public health emergencies.

Pandemic-related life changes and adolescent initiation of cannabis and tobacco/nicotine use

BACKGROUND

The COVID-19 pandemic required the public to alter their daily lives drastically. For adolescents, school closures and social isolation added further challenges to a stressful stage of life, potentially increasing the likelihood of substance use initiation. This study explored the relationship between adolescent substance use initiation and negative life changes due to COVID-19.

METHODS

Students from 9 high schools (N = 2478) in Los Angeles County were surveyed as 9th graders in the 2019-2020 school year and re-surveyed in 10th and 11th grades as part of an ongoing longitudinal study. Two logistic regression models were conducted to test hypotheses that negative life changes due to the COVID-19 pandemic increases the odds of initiation of both tobacco/nicotine products and cannabis products, controlling for sex, age, and race/ethnicity.

RESULTS

The final analytic sample included adolescents in 10th grade who were never-users of tobacco/nicotine (N = 809) and cannabis (N = 837). The odds of initiating cannabis use increased by 6.42% for every 1 standard deviation increase in the COVID-19 negative daily life changes index [AOR: 1.063; 95% CI: 1.010, 1.121]. The association between the COVID-19 negative daily life changes index and tobacco/nicotine use initiation was not significant.

DISCUSSION

Adolescents who experienced life changes due to COVID-19 were more likely to initiate cannabis use, but not tobacco/nicotine use. Results identify a need for early intervention efforts to promote effective coping skills and prevent cannabis initiation among adolescents during a wide-scale stressor, such as COVID-19.

Awareness and use of tobacco products among underage individuals: findings from the altria client services underage tobacco use survey 2020-2022

BACKGROUND

Tobacco use among underage individuals is a public health concern. Timely data about tobacco products, especially emerging products such as novel oral nicotine products (NPs), can provide critical information for the prevention of underage tobacco use. With a recent federal law raising the legal age of purchase of tobacco products from 18 to 21, it is of interest to benchmark awareness and use of tobacco products in the new underage population, young adults 18-20 years old. This study provides estimates on awareness and use of tobacco products among underage individuals 13-20 years old during May 2020 to August 2022 in the United States.

METHODS

Altria Client Services Underage Tobacco Use Survey (UTUS) is a repeated cross-sectional survey conducted every quarter-year. A stratified random sampling approach was used to draw nationally representative samples of household dwelling individuals 13-20 years old. Information about the awareness and use of tobacco products was obtained via online self-administration or phone interviews after a consent/assent process.

RESULTS

A sizable portion of underage individuals were aware of NPs (~ 40% among youth and ~ 50% among underage young adults), although past 30-day use was low (< 2%). The lowest levels of awareness and use were observed for heated tobacco products and snus. E-cigarettes were the most used tobacco products among underage individuals. Underage young adults (i.e., 18-20 year olds) were more likely to use tobacco products than youth (i.e., 13-17 year olds). There was no substantial change over time in the awareness and use of tobacco products during the study period despite a slight increase in past 30-day prevalence of e-cigarette use among youth between quarter 1 of 2021 and quarter 2 of 2022.

CONCLUSIONS

The awareness and use of tobacco products remained relatively stable between May 2020 and August 2022. There is a notable level of awareness of novel NPs among underage individuals.

Public support for policies to regulate flavoured tobacco and e-cigarette products in rural California

INTRODUCTION

Flavoured tobacco control policy exemptions and electronic cigarette products may contribute to increased youth access and tobacco use disparities.

METHODS

We assessed public support among California Central Valley residents for four policies to regulate flavoured tobacco products and e-cigarettes. The probability-based, multimode survey was conducted with English-speaking and Spanish-speaking registered voters (n=845) across 11 counties between 13 and 18 August 2020. Weighted logistic regression analyses measured odds of policy support, adjusting for predictor variables (attitudes and beliefs) and covariates.

RESULTS

The weighted sample was 50% female and predominantly Latino (30%) or non-Hispanic white (46%); 26% had a high school education or less, and 22% an annual household income

DISCUSSION

Findings add to mounting evidence of support for policies to regulate flavoured tobacco and e-cigarette products. Results on attitudes and beliefs elucidate how these factors influence support.

The COVID-19 pandemic: asthma control, tobacco use, and mental health among African American and Latinx college students

OBJECTIVE

This study investigated the impact of COVID-19 on tobacco use and mental health in US African American and Latinx college students with asthma. Associations among asthma control, tobacco use, and mental health were also examined.

METHODS

105 African American and Latinx college students with asthma (18-23 years) completed two online questionnaires (June 2019-March 2020 for Time 1; August 2020-October 2020 for Time 2). Participants completed the Epidemic-Pandemic Impacts Inventory (measure of COVID-19 impact), Asthma Control Test, Generalized Anxiety Disorder scale, Patient Health Questionnaire (measure of depression), Perceived Stress Scale, and items related to tobacco use.

RESULTS

Asthma control improved (t = -3.326, p = 0.001) from Time 1 to 2, and e-vapor product use decreased (χ²₁₀₄ = 6.572, p = 0.010). COVID-19 impact was positively associated with students' symptoms of anxiety, depression, and perceived stress (B = 0.201, p < 0.001; B = 0.179, p < 0.001; and B = 0.199, p = 0.001, respectively) at Time 2. These results remained significant with the Benjamini-Hochberg correction. Asthma control at Time 1 was negatively associated with anxiety symptoms at Time 2 (B = -0.418, p = 0.023); however, associations with perceived stress (B = -0.514, p = 0.019) and all other tobacco product use (B = -0.233, p = 0.030) did not remain significant with the Benjamini-Hochberg correction.

CONCLUSIONS

As hypothesized, a higher COVID-19 impact score was associated with students endorsing more mental health symptoms. Better control of asthma symptoms before the pandemic predicted fewer anxiety symptoms during the pandemic.

COVID-19 Restrictions and Adolescent Cigarette and E-cigarette Use in California

INTRODUCTION

Shelter-in-place orders altered facilitators and barriers to tobacco use (e.g., outlet closures, restricted social gatherings). This study examined whether the duration of time in shelter in place and compliance with different shelter-in-place orders influenced adolescent cigarette and E-cigarette use and how the use may differ by demographic characteristics.

METHODS

Shelter-in-place policy data obtained from government websites were merged with cross-sectional 2020 survey data on adolescents in California. Treatment variables included the proportion of time in shelter in place and self-reported compliance with shelter-in-place orders (for essential businesses and retail spaces and social and outdoor contexts). Multilevel logit models for dichotomous past 6-month cigarette and E-cigarette use and multilevel negative binomial regression models for past 6-month frequency of use were used. Moderation analyses were conducted on demographic measures. The sample included 1,196 adolescents (mean age=15.8 years, age range=13-19 years, 49.2% female, 50.0% White). Analyses were conducted in 2022.

RESULTS

No associations were found between the proportion of time in shelter in place and outcomes. Shelter-in-place compliance with essential business and retail space orders was associated with lower odds of using cigarettes and E-cigarettes in the past 6 months. Compliance with social and outdoor context-related orders were associated with lower odds of using E-cigarettes and fewer days using cigarettes and E-cigarettes. Being aged ≥18 years moderated the associations between essential business/retail space and social/outdoor context-related shelter-in-place compliance orders and past 6-month frequency of cigarette smoking.

CONCLUSIONS

Findings support tailored interventions for less compliant and older adolescents for future pandemic mitigation measures.

E-cigarette Marketing Expenditures in the United States From 2016 to 2021: Targeted Media Outlets Geared Toward People Who Are at Increased Risk for Tobacco Use

INTRODUCTION

E-cigarette advertising exposure is linked to e-cigarette initiation and use. Thus, monitoring trends in e-cigarette advertising practices is important to understand e-cigarette use patterns observed over recent years.

AIMS AND METHODS

E-cigarette advertising expenditures (January 2016-July 2021; Numerator Ad Intel) for 154 U.S. market areas were harmonized with U.S. Census sociodemographic data through Nielsen zip code designations by market area. Descriptive statistics and multivariable linear regressions were used to examine trends in e-cigarette advertising expenditures across media outlets and associations between sociodemographic characteristics and e-cigarette advertising over time.

RESULTS

E-cigarette advertising expenditures peaked in 2018/2019, followed by a sharp decline in 2020. Expenditures were concentrated primarily on print (58.9%), TV (20.6%), and radio (14.4%). Major print outlets were Sports Illustrated, Rolling Stone, and Star magazines. Top TV channels were AMC, Investigation Discovery, and TBS. TV advertisements were purchased commonly during popular movies and TV series (eg King of Queens, Everybody Loves Raymond, The Walking Dead). Higher expenditures were associated with U.S. market areas that had (1) a larger percentage of non-rural zip codes (radio), (2) smaller male populations (radio), and (3) larger White or Caucasian, Black or African American, American Indian or Alaska Native, Asian, and Other or Multiracial populations (radio, print, online display, and online video).

CONCLUSIONS

E-cigarette companies advertised in print magazines geared toward males and youth and young adults, radio commercials focused in urban areas with smaller male populations, and nationwide TV commercials. Declines in e-cigarette advertising expenditures in 2020 demonstrate the potential impact that federal policies may have on protecting populations who are at higher risk for tobacco use from predatory advertising practices.

IMPLICATIONS

E-cigarette advertising exposure is associated with the initiation and use of e-cigarettes. This study shows how e-cigarette marketing expenditures in the United States may have targeted specific consumers (eg youth and young adults) between 2016 and 2021. The precipitous drop in advertising expenditures across all outlets during early 2020 corresponds with the implementation of the Tobacco 21 federal policy, the federal enforcement policy to remove most unauthorized flavored e-cigarette cartridges from the U.S. market, preparations for FDA's premarket review of e-cigarette products, and the decision by several TV broadcast companies to stop showing e-cigarette ads. The potential impact of federal policies may have far-reaching implications for protecting populations who are at high risk for tobacco use and its health consequences.

E-Cigarette Users' Profiles and Their Association with Identified Impacts of COVID-19 on Vaping among Young Adults in Malaysia

Electronic cigarettes (ECs) users' profiles and behaviors during the COVID-19 pandemic remain unclear. This cross-sectional study aimed to explore Malaysian EC users' profiles and their associations with related behaviors during the pandemic. The EC users (N = 351) were recruited from an official national vape entity. Respondents were predominantly of Malay ethnicity (90.6%), aged 31 to 35 years (27.6%), males (97.7%), married (68.7%), from Malaysia's west region states (63.5%) and tertiary educated (69.2%). The majority (80.3%) were non-dual users, and most purchased their vaping products online (77.2%), liked that they can vape while working at home (83.8%) and vaped more because of boredom (55.3%), had low and moderate nicotine addiction levels (94.9%), had low motivation level to quit EC use (92.6%) and were more likely to perceive that vaping did not increase the chances of complications from COVID-19. Respondents with moderate to high addiction levels had twice the odds of checking on their current EC supplies, whilst respondents with low motivation to quit had higher odds of using their tank/pod until the last drop and distancing from others when vaping. EC users should be encouraged to quit EC use, especially during the COVID-19 pandemic.

Underage Youth Continue to Obtain E-Cigarettes from Retail Sources in 2022: Evidence from the Truth Continuous Tracking Survey

(1) Background: This study aims to describe the primary sources of e-cigarettes among young people and to explore how these sources may differ by individual-level characteristics. (2) Methods: Data were obtained from a cross-sectional, continuous tracking survey of participants. The analytic sample includes current e-cigarette users (aged 15-20 years) surveyed from January to August 2022 (N = 1296). Respondents provided information on e-cigarette source of acquisition, device type, and flavors used, as well as sociodemographic and residential characteristics. Chi-square tests were used to determine differences in source of acquisition by age, gender, race/ethnicity, United States (US) census region, urban-rural classification, flavors used, and device type. (3) Results: Although most current e-cigarette users obtained their devices through a social source (56.9%), a considerable proportion obtained e-cigarettes from a retail source (43.1%). The primary retail sources of e-cigarette acquisition were vape shops (22.0%) and gas station/convenience stores (15.9%). Source of e-cigarette acquisition differed by age, gender, US census region, flavors used, and device type, such that a lower proportion of those who were younger, female, residing in the West, and used vape pens had reported obtaining e-cigarettes via retail sources. (4) Conclusions: Results indicate that a significant proportion of youth report obtaining e-cigarettes from retail sources, despite the federal, state, and local policies that prohibit the sale of any tobacco products to those under the age of 21. Comprehensive retail regulations to help restrict tobacco product access are needed to reduce e-cigarette use among young people.

A resurgence of e-cigarette use among adolescents and young adults late in the COVID-19 pandemic

BACKGROUND

Early in the COVID-19 pandemic, e-cigarette use significantly declined among young people due, in part, to losing access through social sources. As the pandemic progressed, adolescents and young adults gained opportunities to resume contact with peers. This study sought to determine whether e-cigarette use has returned to pre-pandemic levels among adolescents and young adults.

METHODS

Data were drawn from a cross-sectional weekly survey of adolescents (aged 15-17) and young adults (aged 18-24) (N = 37,331). Logistic regression analyses measured odds of past 30-day e-cigarette use among respondents surveyed (a) late in the pandemic (April 2021-April 2022) compared to early in the pandemic (March-July 2020) and (b) late in the pandemic (August-December 2021) compared to prior to the pandemic (August-December 2019).

RESULTS

The odds of current e-cigarette use were significantly higher later in the COVID-19 pandemic (April 2021-April 2022), compared to its initial months (March-July 2020) (OR:1.27, 95% CI: 1.17-1.38; p = 0.001). There was no significant difference in the odds of e-cigarette use for youth and younger adults late in the pandemic (August-December 2021) compared to the same time period prior to the pandemic (August-December 2019), but odds were greater for young adults aged 21 years or older (OR:1.16; 95% CI: 1.01-1.32; p = 0.030).

CONCLUSIONS

E-cigarette use has returned to pre-pandemic levels among adolescents and young adults. Young adults over age 21 are more likely to use e-cigarettes than young adults of the same age surveyed prior to the pandemic. Findings have implications for targeted e-cigarette prevention and cessation efforts.

Potential Impact of the COVID-19 Pandemic on Public Perception of Water Pipes on Reddit: Observational Study

Background

Socializing is one of the main motivations for water pipe smoking. Restrictions on social gatherings during the COVID-19 pandemic might have influenced water pipe smokers' behaviors. As one of the most popular social media platforms, Reddit has been used to study public opinions and user experiences.

Objective

In this study, we aimed to examine the influence of the COVID-19 pandemic on public perception and discussion of water pipe tobacco smoking using Reddit data.

Methods

We collected Reddit posts between December 1, 2018, and June 30, 2021, from a Reddit archive (PushShift) using keywords such as "waterpipe," "hookah," and "shisha." We examined the temporal trend in Reddit posts mentioning water pipes and different locations (such as homes and lounges or bars). The temporal trend was further tested using interrupted time series analysis. Sentiment analysis was performed to study the change in sentiment of water pipe-related posts before and during the pandemic. Topic modeling using latent Dirichlet allocation (LDA) was used to examine major topics discussed in water pipe-related posts before and during the pandemic.

Results

A total of 45,765 nonpromotion water pipe-related Reddit posts were collected and used for data analysis. We found that the weekly number of Reddit posts mentioning water pipes significantly increased at the beginning of the COVID-19 pandemic (P<.001), and gradually decreased afterward (P<.001). In contrast, Reddit posts mentioning water pipes and lounges or bars showed an opposite trend. Compared to the period before the COVID-19 pandemic, the average number of Reddit posts mentioning lounges or bars was lower at the beginning of the pandemic but gradually increased afterward, while the average number of Reddit posts mentioning the word "home" remained similar during the COVID-19 pandemic (P=.29). While water pipe-related posts with a positive sentiment were dominant (12,526/21,182, 59.14% before the pandemic; 14,686/24,583, 59.74% after the pandemic), there was no change in the proportion of water pipe-related posts with different sentiments before and during the pandemic (P=.19, P=.26, and P=.65 for positive, negative, and neutral posts, respectively). Most topics related to water pipes on Reddit were similar before and during the pandemic. There were more discussions about the opening and closing of hookah lounges or bars during the pandemic.

Conclusions

This study provides a first evaluation of the possible impact of the COVID-19 pandemic on public perceptions of and discussions about water pipes on Reddit.

Exploring young adults' e-cigarette use behavior during COVID-19

INTRODUCTION

Changes in daily life related to COVID-19 have impacted e-cigarette use, particularly in young adults. This cross-sectional mixed-methods study explored young adults' perceptions regarding how COVID-19 influenced their e-cigarette use.

METHODS

We analyzed Fall 2020 survey data from 726 past 6-month e-cigarette users (mean age=24.15 years, 51.1% female, 35.5% sexual minority, 4.4% Black, 10.2% Asian, 12.1% Hispanic) and Spring 2021 semi-structured interview data among a subset of 40 participants (mean age=26.30 years, 35.0% female, 45.0% sexual minority, 5.0% Black, 22.5% Asian, 12.5% Hispanic). Participants were drawn from 6 metropolitan statistical areas with varied tobacco and cannabis legislative contexts.

RESULTS

Among survey participants, 44.4% also smoked cigarettes, 54.0% other tobacco products, and 60.1% used cannabis. They reported various changes in their daily lives, including changes in the nature and/or status of employment (e.g. 15.3% were laid off, 72.8% experienced household income loss). Regarding changes in e-cigarette use since COVID-19, 22.6% tried to cut down and 16.0% tried to quit. Interview participants commonly indicated that they increased their use due to stress, boredom, changes in accessibility, and/or changes to daily environment that made e-cigarette use more feasible.

CONCLUSIONS

Results highlight the importance of promoting opportunities for young adults to build relationships to decrease stress, foster a sense of belonging, and increase quality of life (e.g. increasing the accessibility to mental health and social support services, intentionally engaging young adults in pandemic-appropriate community-building and extracurricular activities). This research may help to inform future e-cigarette cessation interventions that consider the unique challenges of societal stressors, such as pandemics.

Perceptions and Aspirations Toward Peer Mentoring in Social Media-Based Electronic Cigarette Cessation Interventions for Adolescents and Young Adults: Focus Group Study

BACKGROUND

Social media offer a promising channel to deliver e-cigarette cessation interventions to adolescents and young adults (AYAs); however, interventions delivered on social media face challenges of low participant retention and decreased engagement over time. Peer mentoring has the potential to ameliorate these challenges.

OBJECTIVE

The aim of this study was to understand, from both the mentee and potential mentor perspective, the needs, expectations, and concerns of AYAs regarding peer mentoring to inform the development of social media-based peer mentoring interventions for e-cigarette cessation among AYAs.

METHODS

Seven focus groups, including four mentee groups and three potential mentor groups, were conducted with 26 AYAs who had prior experience with e-cigarette use and attempts to quit in the context of a social media-based e-cigarette cessation intervention. Discussion focused on preferred characteristics of peer mentors, expectations about peer mentoring, mentoring mode, mentor training, incentives for peer mentors, preferred social media platforms for intervention delivery, supervision, and concerns. Focus group transcripts were coded and analyzed using a thematic analysis approach.

RESULTS

Overall, participants were receptive to peer mentoring in social media-based cessation interventions and believed they could be helpful in assisting e-cigarette cessation. Participants identified the most important characteristics of peer mentors to be of similar age and to be abstinent from e-cigarette use. Participants expected peer mentors would share personal experiences, provide emotional support, and send check-ins and reminders. Peer mentors supporting a group of mentees in combination with one-on-one mentoring as needed was the preferred mentoring mode. A group of 10 mentees with a mentor:mentee ratio of 1:3-5 was deemed acceptable for most participants. Participants expressed that mentor training should include emotional intelligence, communication skills, and the scientific evidence about e-cigarettes. Although monetary incentives were not the main motivating factor for being a peer mentor, they were viewed as a good way to compensate mentors' time. Instagram was considered an appropriate social media platform to deliver a peer-mentored intervention due to its functionality. Participants did not express many privacy concerns about social media-based peer mentoring, but mentioned that boundaries and community agreements should be set to keep relationships professional.

CONCLUSIONS

This study reflects the needs and preferences of young people for a peer mentoring intervention to complement a social media program to support e-cigarette cessation. The next step will be to establish the feasibility, acceptability, and preliminary efficacy of such a peer mentoring program.

Changes in Availability of ENDS: 2019-2020, U.S

INTRODUCTION

Events during 2019 and 2020, such as the outbreak of e-cigarette, or vaping, product use‒associated lung injury; manufacturer product withdrawals; federal regulations; and coronavirus disease 2019, potentially affected the retail availability of ENDS in the U.S. Measuring changes in ENDS availability informs the understanding of the ENDS marketplace and contextualizes sales trends.

METHODS

Joinpoint regression was used to estimate slope changes in the number of available ENDS in 2019 and 2020 and considered correspondence with tobacco marketplace events. Availability, the weekly number of unique universal product codes with nonzero sales, was derived from NielsenIQ scanner data. U.S. ENDS availability was modeled overall and by subproduct and flavor category within subproduct: mint, menthol, tobacco flavored, and undetermined.

RESULTS

ENDS availability increased by 66% from January 2019 to December 2020. Availability decreased by 43% among prefilled cartridges and increased by 511% among disposables, both led by flavored varieties. During January 2020-February 2020, prefilled cartridge availability decreased by 23.71 universal product codes per week. During July 2020-August 2020, disposable availability increased by 27.90 universal product codes per week, led by flavored products.

CONCLUSIONS

ENDS availability increased during 2019 through 2020, led by a rise in flavored disposables. Multiple slope changes in ENDS availability occurred, many coinciding with tobacco marketplace events. The slope of ENDS explicitly prioritized for federal enforcement (i.e., flavored prefilled cartridges) notably decreased in early 2020 and, soon thereafter, the slope of ENDS not explicitly prioritized for enforcement (e.g., flavored disposables) notably increased, suggesting an association with U.S. Food and Drug Administration's prioritized enforcement guidance.

Factors affecting tobacco, nicotine, and cannabis product use among California young adults during the COVID-19 pandemic: A qualitative study

The effects of COVID-19 on tobacco use and cannabis has been variable, and it is unclear the extent to which factors affecting changes in tobacco and cannabis use differ. The purpose of this study was to identify the COVID-19-related factors that affect changes in tobacco and cannabis use during the pandemic. Focus groups with 114 young adults in California in April 2021 were held to discuss tobacco and cannabis use patterns, adverse events, and the effect of COVID-19 on tobacco and cannabis product use. Factors affecting changes in use were largely similar between tobacco products and cannabis products. Drivers of increased cannabis use distinct from tobacco or nicotine product use included feeling greater freedom to disengage and perceptions of less harm. Increases in product use were a result of changing social environment, coping with emotional and psychological distress, and product related factors. Decreases in product use were a result of social isolation, COVID-19-related health concerns, disruptions in daily patterns of living, and reduced access. Improved understanding of how the pandemic has affected tobacco and cannabis use can inform tailored interventions to both support those who have decreases or quit and assist those who have increased use during the pandemic to reduce or cease their consumption.

Knowledge, beliefs, attitude, and practices of E-cigarette use among dental students: A multinational survey

Background

E-cigarette use is a trend worldwide nowadays with mounting evidence on associated morbidities and mortality. Dentists can modify the smoking behaviors of their patients. This study aimed to explore the knowledge, beliefs, attitude, and practice of E-cigarette use among dental students.

Materials and methods

This multinational, cross-sectional, questionnaire-based study recruited undergraduate dental students from 20 dental schools in 11 countries. The outcome variable was current smoking status (non-smoker, E-cigarette user only, tobacco cigarette smoker only, dual user). The explanatory variables were country of residence, sex, age, marital status, and educational level. Multiple linear regression analysis was performed to explore the explanatory variables associated with E-cigarette smoking.

Results

Of the 5697 study participants, 5156 (90.8%) had heard about E-cigarette, and social media was the most reported source of information for 33.2% of the participants. For the 5676 current users of E-cigarette and/or tobacco smoking, 4.5% use E-cigarette, and 4.6% were dual users. There were significant associations between knowledge and country (P< 0.05), educational level (B = 0.12; 95% CI: 0.02, 0.21; P = 0.016) and smoking status (P< 0.05). The country of residence (P< 0.05) and smoking status (P< 0.05) were the only statistically significant factors associated with current smoking status. Similarly, there were statistically significant associations between attitude and country (P< 0.05 for one country only compared to the reference) and history of previous E-cigarette exposure (B = -0.52; 95% CI: -0.91, -0.13; P = 0.009). Also, the practice of E-cigarettes was significantly associated with country (P< 0.05 for two countries only compared to the reference) and gender (B = -0.33; 95% CI: -0.52, -0.13; P = 0.001).

Conclusion

The knowledge of dental students about E-cigarette was unsatisfactory, yet their beliefs and attitudes were acceptable. Topics about E-cigarette should be implemented in the dental curriculum.

Association of Residence Type on Smoking in South Korean Adolescents during the COVID-19 Pandemic: Findings from a National Survey

The closure of schools due to the COVID-19 pandemic has forced adolescents to stay home. These disruptions, as well as a significant decrease in social access, have impacted smoking behavior. This study identified the association between the adolescents' type of residence and tobacco product use. A cross-sectional study (using data from the Korea Youth Risk Behavior Web-based Survey) examined 3774 students in 2019 (pre-pandemic) and 2575 students in 2020 (during the pandemic). The participants were South Korean middle and high school students aged 13-19 years. Using multinomial logistic regression, it was shown that adolescents who lived alone or in a boarding house had a higher risk of being an e-cigarette smoker compared with those who lived with family or relatives (OR = 6.49, CI = 2.06-20.45). Living in a dormitory or orphanage also increased the risk of dual tobacco use compared with living with family (OR = 2.09, 95% CI = 1.13-3.84). With the advent and continuation of the COVID-19 pandemic, this effect became more significant in 2020 than in 2019. Our findings support the theory that residential differences affect adolescent smoking behavior and highlight the importance of integrated smoking bans and educational programs to control adolescent smoking.

California School Staff Reports of Seeing Students Vaping at School and Disciplinary Actions

Youth vaping is a concern and schools may use many approaches to discipline students caught vaping at school. This study identified the prevalence of school staff seeing vaping in schools and the measures used to discipline students. A state-wide sample of 7,938 staff from 255 middle and high schools reported whether they saw any students vaping at school in the last 30 days, whether they have caught any students vaping during class in the last semester, and what happened after catching a student vaping in class. Open-text responses were coded and themes were identified related to disciplinary approaches. 31.9% of staff reported seeing students vaping at school, and 11.9% of teachers reported catching a student vaping during class. Teachers described four categories of disciplinary approaches after catching students vaping in class: no consequences, punitive approaches, restorative approaches, and mixed approaches. Additional support is necessary to help schools address student vaping.

"I don't know whose mouth has been on this": youth nicotine and cannabis vaping practices in the context of the COVID-19 pandemic

Early COVID-19 safety protocols urged physical and social distancing, resulting in minimal contact with others. As social contexts are central to vaping among youth, we used semi-structured interviews to describe how youth who vape are making sense of their use practices and adaptations. The qualitative analyses revealed changes in vaping frequency and access, social isolation shaping substance- and product-specific use, and motivations and outcomes of dual use of nicotine and cannabis which were closely linked to the pandemic. The findings indicate variation of youth vaping experiences within the early stages of the pandemic that should be attended to in future studies.

Tobacco product use and the risks of SARS-CoV-2 infection and COVID-19: current understanding and recommendations for future research

Heterogeneity in the clinical presentation of SARS-CoV-2 infection and COVID-19 progression underscores the urgent need to identify individual-level susceptibility factors that affect infection vulnerability and disease severity. Tobacco product use is a potential susceptibility factor. In this Personal View, we provide an overview of the findings of peer-reviewed, published studies relating tobacco product use to SARS-CoV-2 infection and COVID-19 outcomes, with most studies focusing on cigarette smoking in adults. Findings pertaining to the effects of tobacco product use on the incidence of SARS-CoV-2 infection are inconsistent. However, evidence supports a role for cigarette smoking in increasing the risk of poor COVID-19 outcomes, including hospital admission, progression in disease severity, and COVID-19-related mortality. We discuss the potential effects of tobacco use behaviour on SARS-CoV-2 transmission and infection, and highlight the pathophysiological changes associated with cigarette smoking that could promote SARS-CoV-2 infection and increased disease severity. We consider the biological mechanisms by which nicotine and other tobacco product constituents might affect immune and inflammatory responses to SARS-CoV-2 infection. Finally, we identify current knowledge gaps and suggest priorities for research to address acute and post-acute health outcomes of COVID-19 during and after the pandemic.

Consumption of JUUL vs. Other E-Cigarette Brands among U.S. E-Cigarette Users: Evidence from Wave 5 of the PATH Study

This study examines the use of JUUL vs. other e-cigarette brands among U.S. youth (12-17 years), young adult (18-24 years), and adult (25 years and above) e-cigarette users. Data were from the Population Assessment of Tobacco and Health (PATH) study Wave 5 survey (2019). The study population was past 30-day e-cigarette users who knew the brand of e-cigarettes they usually/last used (N = 2569). JUUL use was reported by 65.2% of youth, 60.7% of young adult, and 25.6% of adult e-cigarette users in our study sample. The share of JUUL consumed in the past 30 days, measured by the total number of puffs, was 15.4% by youth, 55.5% by young adults, and 29.1% by adults. By contrast, the share of other e-cigarettes consumed was 4.2% by youth, 28.9% by young adults, and 66.9% by adults. Youth JUUL users were more likely to use e-cigarettes within 30 min after waking (aOR = 2.30, 95% CI: 1.12-4.75) than youth users of other brands of e-cigarettes. Additionally, youth e-cigarette users who currently smoked cigarettes were less likely to use JUUL (aOR = 0.55, 95% CI: 0.30-0.99). This study concludes that JUUL consumption was disproportionally higher among youth and young adults in the U.S. in 2019.

Cigarettes' use and capabilities-opportunities-motivation-for-behavior model: a multi-country survey of adolescents and young adults

The use of cigarettes among adolescents and young adults (AYA) is an important issue. This study assessed the association between regular and electronic-cigarettes use among AYA and factors of the Capability-Motivation-Opportunity-for-Behavior-change (COM-B) model. A multi-country survey was conducted between August-2020 and January-2021, Data was collected using the Global-Youth-Tobacco-Survey and Generalized-Anxiety-Disorder-7-item-scale. Multi-level logistic-regression-models were used. Use of regular and electronic-cigarettes were dependent variables. The explanatory variables were capability-factors (COVID-19 status, general anxiety), motivation-factors (attitude score) and opportunity-factors (country-level affordability scores, tobacco promotion-bans, and smoke free-zones) controlling for age and sex. Responses of 6,989-participants from 25-countries were used. Those who reported that they were infected with COVID-19 had significantly higher odds of electronic-cigarettes use (AOR = 1.81, P = 0.02). Normal or mild levels of general anxiety and negative attitudes toward smoking were associated with significantly lower odds of using regular-cigarettes (AOR = 0.34, 0.52, and 0.75, P < 0.001) and electronic-cigarettes (AOR = 0.28, 0.45, and 0.78, P < 0.001). Higher affordability-score was associated with lower odds of using electronic-cigarettes (AOR = 0.90, P = 0.004). Country-level-smoking-control policies and regulations need to focus on reducing cigarette affordability. Capability, motivation and opportunity factors of the COM-B model were associated with using regular or electronic cigarettes.

Adolescents, Young Adults, and Adults Continue to Use E-Cigarette Devices and Flavors Two Years after FDA Discretionary Enforcement

This study assesses the use of e-cigarette devices and flavors using a large, cross-sectional survey of adolescents, young adults, and adults (N = 6131; ages 13−40 years old; Mage = 21.9) conducted from November to December 2021, 22 months after the FDA announced its prioritized enforcement policy against some flavored pod/cartridge-based e-cigarettes. We analyzed the patterns of use by age group: adolescents and young adults (AYAs) under 21 (minimum age of e-cigarette sales), young adults (21−24 years old), and adults (25−40 years old). The participants reported using e-cigarettes ever (44.2% < 21; 67.1% 21−24; 58.0% > 24), in the past 30 days (29.8% < 21; 52.6% 21−24; 43.3% > 24), and in the past 7 days (24.5% < 21; 43.9% 21−24; 36.5% > 24). Disposables were the most used e-cigarette device type across age groups (39.1% < 21; 36.9% 21−24; 34.5% > 24). Fruit, sweet, mint, and menthol flavors were popular across age groups; however, chi-squared tests for trends in proportions revealed age-related trends in past 30-day flavor use by device type. Findings suggest current AYA e-cigarette use may be higher than recorded by the NYTS 2021. The FDA, states, and localities should adopt more comprehensive restrictions on flavored e-cigarette products in order to reduce adolescent and young adult e-cigarette use.

Belief and Recall of Nicotine as Therapeutic for COVID-19 May Undermine E-Cigarette Quitting Behavior

We examine the proposition that misinformation about the therapeutic potential of nicotine to prevent or treat COVID-19 may lead to relapse among attempted e-cigarette quitters. A sample of N = 507 e-cigarette ever-users who reported at least one quit attempt in the past year were surveyed in June of 2021 for recall and belief in several claims about COVID-19 and nicotine. Participants who recalled and believed at least one misinformation claim were significantly more likely to have relapsed than those who did not recall or believe such claims. These differences remained robust to regression analysis adding demographic covariates and accounting for continuous measurement of recall and belief. Misinformation about e-cigarette use is reaching young adult e-cigarette users who are trying to quit. The implications of these findings merit further research to characterize potential barriers to successful e-cigarette cessation.

Cardiopulmonary Consequences of Vaping in Adolescents: A Scientific Statement From the American Heart Association

Although the US Food and Drug Administration has not approved e-cigarettes as a cessation aid, industry has at times positioned their products in that way for adults trying to quit traditional cigarettes; however, their novelty and customizability have driven them into the hands of unintended users, particularly adolescents. Most new users of e-cigarette products have never smoked traditional cigarettes; therefore, understanding the respiratory and cardiovascular consequences of e-cigarette use has become of increasing interest to the research community. Most studies have been performed on adult e-cigarette users, but the majority of these study participants are either former traditional smokers or smokers who have used e-cigarettes to switch from traditional smoking. Therefore, the respiratory and cardiovascular consequences in this population are not attributable to e-cigarette use alone. Preclinical studies have been used to study the effects of naive e-cigarette use on various organ systems; however, almost all of these studies have used adult animals, which makes translation of health effects to adolescents problematic. Given that inhalation of any foreign substance can have effects on the respiratory and cardiovascular systems, a more holistic understanding of the pathways involved in toxicity could help to guide researchers to novel therapeutic treatment strategies. The goals of this scientific statement are to provide salient background information on the cardiopulmonary consequences of e-cigarette use (vaping) in adolescents, to guide therapeutic and preventive strategies and future research directions, and to inform public policymakers on the risks, both short and long term, of vaping.

Increased nicotine vaping due to the COVID-19 pandemic among US young adults: Associations with nicotine dependence, vaping frequency, and reasons for use

Previous research has not examined increased vaping because of the pandemic using a national sample of young adults (YAs), which is a critical gap because pandemic-related increases in vaping among YAs could have important implications for nicotine dependence, prolonged regular use, and using substances to cope with stress. We examined self-reported increased vaping attributed to the COVID-19 pandemic among YAs, and its associations with outcomes that have important implications for future nicotine use. Data came from the Monitoring the Future (MTF) Vaping Supplement. Participants were selected from a nationally representative sample of US 12th-graders who were surveyed at age 19 in fall 2020 (N = 1244). Cross-sectional analyses of the 2020 survey included YAs who vaped nicotine in the past year (35%; N = 440). Weighted descriptive analyses and logistic regression models examined self-reported pandemic-related increased vaping (vs. decreased vaping, or no change), and its associations with current nicotine dependence, vaping behavior, and reasons for vaping. Among YAs who vaped nicotine in the past year, 16.8% reported increased and 44.4% reported decreased vaping due to the pandemic, while 38.9% reported no change. Increased vaping (vs. decreased and/or no change) was significantly associated with nicotine dependence symptoms, current regular nicotine vaping, and vaping to relax, get high, and because of boredom. Self-reported increased vaping because of the pandemic was associated with increased risk for current nicotine dependence and frequent use. Increased vaping may have been a form of coping with pandemic-related stressors, which increases risk for future substance use problems.

Changes in E-cigarette Use Among Youth and Young Adults During the COVID-19 Pandemic: Insights Into Risk Perceptions and Reasons for Changing Use Behavior

INTRODUCTION

This study assessed changes in e-cigarette use since the COVID-19 pandemic began and reasons for these changes among US youth and young adults.

AIMS AND METHODS

We combined data from two cross-sectional samples of youth and young adult (15-24 years) participants of a monthly surveillance study (data collected in April and June 2021). Analyses were restricted to past-year e-cigarette users who reported using e-cigarettes before the pandemic (n = 1762). Participants reported changes in e-cigarette use since the pandemic began, reasons for changing their behavior, and their perceptions around COVID-19 risk related to e-cigarette use. Multinomial logistic regression models assessed associations between demographics and COVID vaping risk perceptions and changes in e-cigarette use.

RESULTS

Over a third of the sample (37.9%) reported increasing e-cigarette use, while 28.9% reported decreasing use, and 33.1% reported no change. Analyses revealed associations between change in e-cigarette use and age, race and ethnicity, e-cigarette use status, and COVID vaping risk perceptions. The most common reason for increasing use was managing stress (36%); the most common reasons for decreasing use included fewer social interactions (22%) and concerns over general health (18%). Results also indicated differences in reasons for decreasing use by race and ethnicity, and differences in reasons for both increasing and decreasing use by age.

CONCLUSIONS

This study provides recent data on how the ongoing and evolving COVID-19 pandemic has impacted youth and young adults' e-cigarette use. Findings identify subpopulations that may benefit from e-cigarette prevention interventions, as well as insights that may inform the content and delivery of such interventions.

IMPLICATIONS

This study provides recent insights into if and why the ongoing COVID-19 pandemic has impacted e-cigarette use behavior among youth and young adults. Findings contribute to the understanding of the role e-cigarettes play in young people's lives-insights that can inform youth and young adult prevention efforts.
