Neuroscience 2024:S0306-4522(24)00650-X. [PMID: 39631662 DOI: 10.1016/j.neuroscience.2024.11.059] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/01/2024] [Revised: 11/07/2024] [Accepted: 11/24/2024] [Indexed: 12/07/2024]
Abstract
Incidences of seizure after e-cigarette use in adolescents and young adults have been reported, raising the concern about the risk of nicotine overconsumption. Few previous studies have investigated the effects of nicotine at high doses on brain and behavior in adolescent animals. In this study, the effects of a 15-day repeated nicotine treatment at a daily dose of 2 mg/kg body weight were investigated in adolescent and adult male rats. Nicotine treatment abolished body weight gain in the adults, but did not affect the body weight significantly in the adolescents. Only the nicotine-treated adolescents showed significant changes in brain anatomy 1 day post-treatment, which manifested as a significant reduction of whole-brain gray matter (GM) volume, a further reduction of regional GM volume in the medial prefrontal cortex (mPFC) and altered GM volume covariations between the mPFC and a number of brain regions. The mPFC of nicotine-treated adolescent rats did not exhibit evident signs of neuronal degeneration and reactive astrocytosis, but showed a significantly decreased expression of presynaptic marker synaptophysin (SYN), along with a significantly increased oxidative stress and a significantly elevated expressions of microglial marker ionized calcium binding adaptor molecule 1 (IBA1). Together, these results suggested that repeated nicotine overdosing may shift regional redox, modulate microglia-mediated pruning, and give rise to structural/connectivity deficits in the mPFC of adolescent male rats.

Abstract
E-cigarette use is a growing public health concern, especially because of the potential health risks it poses. This study focuses on assessing e-cigarette dependence and the factors associated with it among Palestinian young adults. A cross-sectional survey was conducted from January to May 2023 among university students in the West Bank. A self-administered questionnaire was used to collect demographic data, knowledge, and attitudes regarding e-cigarettes. E-cigarette dependence was assessed using the Penn State Electronic Cigarette Dependence Index. The study included 386 university students who used e-cigarettes. Many of them started using e-cigarettes at a young age, and 54.7% were dual users of e-cigarettes and traditional tobacco. High levels of dependence were reported in 11.4% of participants, and moderate dependence in 28.8%. Several factors were identified through multivariate linear regression as significantly associated with e-cigarette dependence: a higher monthly allowance (β = 0.116, 95% CI: 0.128- 1.124, p = .014), having a father who uses tobacco (β = 0.095, 95% CI: 0.030- 1.638, p = .042), having a close friend who smokes traditional cigarettes (β = 0.095, 95% CI: 0.019- 1.667, p = .045), using e-cigarettes in areas where traditional smoking is prohibited (β = 0.175, 95% CI: 0.689-2.330, p < .001), using e-cigarettes to quit other forms of tobacco (β = 0.134, 95% CI: 0.434-2.314, p = .004), and a more negative attitude score (β = - 0.210, 95% CI: - 0.285- - 0.112, p < .001). The study revealed high levels of e-cigarettes dependence among the participants among young adults, with associated variables such as monthly allowance, attitudes, and age of e-cigarette initiation. Policymakers, educators, and healthcare professionals should collaborate to address e-cigarette dependence among young adults, taking into consideration social, environmental, and socioeconomic factors.

Abstract
Electronic cigarette use among adolescents is a growing concern, not only due to the high incidence of co-use with other substances, such as alcohol, but also due to the fact brain is still maturing during this period. Combined exposure to alcohol and nicotine leads to plastic adaptation of crucial circuits in the brain, which can contribute to the development of addiction. It is well established that nicotine exposure can facilitate alcohol binge drinking, and vice-versa, in a sex-, age- and exposure-dependent manner. Nonetheless, the central mechanisms underlying the synergistic relationship between these two substances and the emergence of differential behavioural traits dependent on these factors remain underexplored. Preclinical studies continue to provide valuable insights into such mechanisms. Here, we discuss recent preclinical findings that report behavioural changes characteristic of addiction following nicotine consumption, primarily in models of vaping and alcohol use; and insights into the neural mechanisms impacted by intake of these two substances, with a focus on the adolescent brain.

Abstract
BACKGROUND With the aim of protecting minors, the World Health Organization has recommended classifying films with smoking scenes as unsuitable for children and adolescents. In recent years, films have increasingly been viewed via video streaming services - a trend which has been intensified by the COVID-19 pandemic - which poses new challenges for the protection of minors. AIM To examine the frequency of smoking scenes in Netflix feature films and the age recommendations for Netflix productions with smoking scenes. METHOD A total of 235 films that were made available for streaming exclusively by the Netflix platform in 2021 and 2022 were content coded in order to find out (1) how high the proportion of smoke-free films was in this film sample, (2) how often smoking scenes occurred in these films and (3) the proportion of films with smoke scenes classified as appropriate for young people in Germany and the USA. All films with an age rating of under 16 were considered suitable for children and young people. RESULTS Smoking scenes occurred in 113 of 235 analyzed films (48.1%). Of the 113 films with smoking scenes, 57 (50.4%) in Germany and 26 films (23.0%) in the USA were classified as youth films (p<0.001). A total of 3,310 smoking scenes were registered. Of these, 39.4% (n=1,303) were in films with youth ratings in Germany, and in Netflix USA this proportion was 15.8% (n=524). DISCUSSION Smoking scenes are a common feature in Netflix movies. Neither in the US nor in Germany does Netflix adhere to the recommendations of the WHO Framework Convention on Tobacco Control to restrict access by young people to films depicting smoking. However, the protection of minors in the US is better than in Germany, since half of the Netflix films with smoking scenes in Germany were rated as suitable for minors, in the USA less than a quarter.

Abstract
Waterpipe tobacco (WPT) smoking is a public health concern, particularly among youth and young adults. The global spread of WPT use has surged because the introduction of pre-packaged flavored and sweetened WPT, which is widely marketed as a safer tobacco alternative. Besides flavorants and sugars, WPT additives include humectants, which enhance the moisture and sweetness of WPT, act as solvents for flavors, and impart smoothness to the smoke, thus increasing appeal to users. In the United States, unlike cigarette tobacco flavoring (with the exception of menthol), there is no FDA product standard or policy in place prohibiting sales of flavored WPT. Research has shown that the numerous fruit, candy, and alcohol flavors added to WPT entice individuals to experience those flavors, putting them at an increased risk of exposure to WPT smoke-related toxicants. Additionally, burning charcoal briquettes-used as a heating source for WPT-contributes to the harmful health effects of WPT smoking. This review presents existing evidence on the potential toxicity resulting from humectants, sugars, and flavorants in WPT, and from the charcoal used to heat WPT. The review discusses relevant studies of inhalation toxicity in animal models and of biomarkers of exposure in humans. Current evidence suggests that more data are needed on toxicant emissions in WPT smoke to inform effective tobacco regulation to mitigate the adverse impact of WPT use on human health.

Abstract
AIM To measure trends in the use of various smoking products among children and adolescents from 2016 to 2023. METHOD The data is based on seven waves of the "Präventionsradar", a school-based epidemiological study in grades 5 to 10. The primary endpoints of the study were the lifetime and monthly prevalence of the use of tobacco cigarettes, e-cigarettes, shisha and the use of at least two of these smoking products (combined use). Prevalence estimates are based on logistic regression models. RESULTS The analysis was based on 94,127 questionnaires. The sex ratio was balanced (49% female), mean age was 13 years (SD=1.8). In 2022/2023, the lifetime prevalence of smoking tobacco cigarettes was 18.8% (95% CI 18.1-19.5), of e-cigarettes 23.5% (95% CI 22.8-24.3), of shisha 14.0% (95% CI 13.4-14.7) and combined use 19.0% (95% CI 18.3-19.7). The monthly prevalence of smoking tobacco cigarettes was 5.9% (95% CI 5.5-6.4), of e-cigarettes 7.0% (95% CI 6.5-7.4), of shisha 3.2% (95% CI 2.8-3.5) and combined use 4.8% (95% CI 4.4-5.2). The following trends in lifetime prevalence have emerged since 2016: tobacco cigarettes (-3.0 percentage points), e-cigarettes (+1.8 percentage points), shisha (-9.2 percentage points), combined use (-2.7 percentage points). In the years of the COVID-19 pandemic, youth smoking decreased and rose again post-COVID with the exception of shisha. DISCUSSION The use of smoking products in adolescence occurs frequently. Over the observational period, a trend reversal towards e-cigarettes as the most popular product among children and young people is most likely. In addition, the combined use of several smoking products has become a common pattern of consumption. Consistent preventive measures are required in order to achieve the goal of a smoke-free society in 2040.

Abstract
Clinical studies demonstrate that the risk of developing neurological disorders is increased by overconsumption of the commonly used drugs, alcohol, nicotine and cannabis. These drug-induced neurological disorders, which include substance use disorder (SUD) and its co-occurring emotional conditions such as anxiety and depression, are observed not only in adults but also with drug use during adolescence and after prenatal exposure to these drugs, and they are accompanied by long-lasting disturbances in brain development. This report provides overviews of clinical and preclinical studies, which confirm these adverse effects in adolescents and the offspring prenatally exposed to the drugs and include a more in-depth description of specific neuronal systems, their neurocircuitry and molecular mechanisms, affected by drug exposure and of specific techniques used to determine if these effects in the brain are causally related to the behavioral disturbances. With analysis of further studies, this review then addresses four specific questions that are important for fully understanding the impact that drug use in young individuals can have on future pregnancies and their offspring. Evidence demonstrates that the adverse effects on their brain and behavior can occur: (1) at low doses with short periods of drug exposure during pregnancy; (2) after pre-conception drug use by both females and males; (3) in subsequent generations following the initial drug exposure; and (4) in a sex-dependent manner, with drug use producing a greater risk in females than males of developing SUDs with emotional conditions and female offspring after prenatal drug exposure responding more adversely than male offspring. With the recent rise in drug use by adolescents and pregnant women that has occurred in association with the legalization of cannabis and increased availability of vaping tools, these conclusions from the clinical and preclinical literature are particularly alarming and underscore the urgent need to educate young women and men about the possible harmful effects of early drug use and to seek novel therapeutic strategies that might help to limit drug use in young individuals.

Abstract
Microscopic colitis (MC) is classified as collagenous colitis (CC) and lymphocytic colitis (LC). Genetic associations between CC and human leucocyte antigens (HLAs) have been found, with smoking being a predisposing external factor. Smoking has a great impact on metabolomics. The aim of this explorative study was to analyze global metabolomics in MC and to examine whether the metabolomic profile differed regarding the type and course of MC, the presence of IBS-like symptoms, treatment, and smoking habits. Of the 240 identified women with MC aged ≤73 years, 131 completed the study questionnaire; the Rome III questionnaire; and the Visual Analog Scale for Irritable Bowel Syndrome (VAS-IBS). Blood samples were analyzed by ultra-high-performance liquid chromatograph mass spectrometry (UHLC-MS/UHPLC-MSMS). The women, 63.1 (58.7-67.2) years old, were categorized based on CC (n = 76) and LC (n = 55); one episode or refractory MC; IBS-like symptoms or not; use of corticosteroids or not; and smoking habits. The only metabolomic differences found in the univariate model after adjustment for false discovery rate (FDR) were between smokers and non-smokers. Serotonin was markedly increased in smokers (p < 0.001). No clear patterns appeared when conducting a principal component analysis (PCA). No differences in the metabolomic profile were found depending on the type or clinical course of the disease, neither in the whole MC group nor in the subgroup analysis of CC.

Abstract
Aim was to investigate the amount of smoking in popular streaming series in Germany with a focus on the comparison between series recommended for adults versus youth. The sample was drawn from the 35 highest user-rated streaming series, that released 1794 new episodes between January 1, 2017 and December 31, 2020. One-third of the episodes (N = 598) were randomly selected and analyzed for smoking content. The age ratings of these episodes ranged from 6 to 18 years, with categories of "6", "12", "16" and "18" years. Ten of the 35 shows (28.6%) were completely smoke-free, 25 shows (71.4%) had at least one episode with smoking. Of all analyzed episodes, 25.1% contained smoking (range = 1 to 36 smoking scenes; median = 4). There was a statistically significant association between episode age rating and the presence of smoking (χ2[3] = 9.1; p = 0.028; Spearman's rho = 0.11): The proportion of episodes with smoking was 0% for episodes with age ratings below 12 years, 20.4% for age ratings "12", 28.3% for age ratings "16", and 32.4% for age ratings "18". This association differed between streaming services, but all services had smoking in episodes rated for youth. Smoking is common in popular streaming series. None of the streaming services meet the recommendations of the WHO Framework Convention on Tobacco Control to reliably restrict young people's access to media content that depicts smoking.

Abstract
To assess the association of regional socioeconomic deprivation and nicotine use, survey data from 17,877 pupils aged 9-17 years were analysed. Lifetime use of combustible, e-cigarettes, and both products were the outcome variables. The German Index of Socioeconomic Deprivation was the exposure variable. Logistic regression models controlling for age, gender, school type, and sensation seeking were used to examine associations between regional socioeconomic deprivation and nicotine use. Ever use of combustible cigarettes was 17.8%, of e-cigarettes 19.6%, and of both products 13.4%. Compared to the most affluent area, the adjusted odds ratio of combustible cigarette use in the most deprived area was 2.24 (95% CI: 1.67-3.00), of e-cigarette use 1.56 (95% CI: 1.20-2.03), and of poly use 1.91 (95% CI: 1.36-2.69). Nicotine use among young people across ages and especially in socioeconomic-deprived areas was widespread. Nicotine control measures are urgently needed to reduce smoking and vaping in German adolescents.

Abstract
Considerable progress has been made in elucidating the relationships between early life psychobiological and environmental risk factors and the development of tobacco addiction. However, a comprehensive understanding of the heterogeneity in tobacco addiction phenotypes requires integrating research findings. The probabilistic epigenesis meta-theory offers a valuable framework for this integration, considering systemic, multilevel, developmental, and evolutionary perspectives. In this paper, we critically review relevant research on early developmental risks associated with tobacco addiction and highlight the integrative heuristic value of the probabilistic epigenesis framework for this research. For this, we propose a four-level systems approach as an initial step towards integration, analyzing complex interactions among different levels of influence. Additionally, we explore a coaction approach to examine key interactions between early risk factors. Moreover, we introduce developmental pathways to understand interindividual differences in tobacco addiction risk during development. This integrative approach holds promise for advancing our understanding of tobacco addiction etiology and informing potentially effective intervention strategies.

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. Prev Med Rep 2023; 36:102416. [PMID: 37753384 PMCID: PMC10518703 DOI: 10.1016/j.pmedr.2023.102416] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Download PDF] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/18/2023] [Revised: 09/11/2023] [Accepted: 09/12/2023] [Indexed: 09/28/2023] Open
Abstract
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.

Abstract
AIM To measure trends in the use of various smoking products among children and adolescents from 2016 to 2023. METHOD The data is based on seven waves of the "Präventionsradar", a school-based epidemiological study in grades 5 to 10. The primary endpoints of the study were the lifetime and monthly prevalence of the use of tobacco cigarettes, e-cigarettes, shisha and the use of at least two of these smoking products (combined use). Prevalence estimates are based on logistic regression models. RESULTS The analysis was based on 94,127 questionnaires. The sex ratio was balanced (49% female), mean age was 13 years (SD=1.8). In 2022/2023, the lifetime prevalence of smoking tobacco cigarettes was 18.8% (95% CI 18.1-19.5), of e-cigarettes 23.5% (95% CI 22.8-24.3), of shisha 14.0% (95% CI 13.4-14.7) and combined use 19.0% (95% CI 18.3-19.7). The monthly prevalence of smoking tobacco cigarettes was 5.9% (95% CI 5.5-6.4), of e-cigarettes 7.0% (95% CI 6.5-7.4), of shisha 3.2% (95% CI 2.8-3.5) and combined use 4.8% (95% CI 4.4-5.2). The following trends in lifetime prevalence have emerged since 2016: tobacco cigarettes (-3.0 percentage points), e-cigarettes (+1.8 percentage points), shisha (-9.2 percentage points), combined use (-2.7 percentage points). In the years of the COVID-19 pandemic, youth smoking decreased and rose again post-COVID with the exception of shisha. DISCUSSION The use of smoking products in adolescence occurs frequently. Over the observational period, a trend reversal towards e-cigarettes as the most popular product among children and young people is most likely. In addition, the combined use of several smoking products has become a common pattern of consumption. Consistent preventive measures are required in order to achieve the goal of a smoke-free society in 2040.

Abstract
Aging is not a disease; it is a natural evolution of human physiology. Medical advances have extended our life expectancy, but chronic diseases and geriatric syndrome continue to affect the increasingly aging population. Yet modern medicine perpetuates an approach based on treatment rather than prevention and education. In order to help solve this ever-growing problem, a new discipline has emerged: lifestyle medicine. Nutrition, physical activity, stress management, restorative sleep, social connection, and avoidance of risky substances are the pillars on which lifestyle medicine is founded. The aim of this discipline is to increase healthspan and reduce the duration of morbidity by making changes to our lifestyle. In this review, we propose the use of klotho protein as a novel biomarker for lifestyle medicine in order to quantify and monitor the health status of individuals, as no integrative tool currently exists.

Tob Induc Dis 2023; 21:123. [PMID: 37799805 PMCID: PMC10548790 DOI: 10.18332/tid/170423] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/17/2023] [Revised: 08/03/2023] [Accepted: 08/05/2023] [Indexed: 10/07/2023] Open
Abstract
INTRODUCTION This study comprehensively assessed the association between eight metabolites of urinary nicotine and cognitive impairment. METHODS This cross-sectional study was based on the data of Shenzhen Aging Related Disorder Cohort (SADC), including 51 elderly community data variables such as demographic characteristics, neuropsychological assessment and environmental factors, from July 2017 to November 2018. Participant's cognitive function was assessed by Mini-Mental State Examination (MMSE) scale and urinary nicotine metabolite [including cotinine N-β-D-glucuronide (CotGluc), rac 4-hydroxy-4-(3-pyridyl) butanoic acid dicyclohexylamine salt (HyPyBut), trans-3'-hydroxy cotinine O-β-D-glucuronide (OHCotGluc), and cotinine (Cot), etc.] concentrations were measured by high-performance liquid chromatography-tandem mass spectrometry (LC-MS/MS). Generalized linear models and restricted cubic spline models were used to explore the relationships between the urinary levels of nicotine metabolite and cognitive function. RESULTS A total of 296 individuals aged >60 years were included. Individuals in the third quartile of CotGluc had a 0.786 point (95% CI: -1.244 - -0.329) decrease or in the highest quartile of OHCotGluc had a 0.804 point (95% CI: -1.330 - -0.278) decreased in attention and calculation compared to those in the lowest quartile (all p for trend <0.05). Compared with those in the lowest quartile, individuals in the highest quartile of CotGluc, HyPyBut, OHCotGluc and Cot, respectively, corresponded to a 1.043 point (95% CI: -2.269-0.182), 1.101 points (95% CI: -2.391-0.188), 2.318 points (95% CI: -3.615 - -1.020), and 1.460 points (95% CI: -2.726 - -0.194) decreased in MMSE total score (all p for trend <0.05). A non-linear dose-response relationship between urinary levels of CotGluc, HyPyBut, OHCotGluc or Cot and cognitive function (all overall p<0.05, non-linear p<0.05). Subgroup analysis showed that urinary levels of CotGluc, OHCotGluc or Cot were significantly negatively associated with cognitive function (all p for trend <0.05) among females and non-smokers. CONCLUSIONS The findings highlight the public health implications of environmental tobacco smoke exposure, and effective interventions need to be performed for vulnerable populations.

Abstract
This study examines e-cigarette use behaviors of Asian American, Native Hawaiian, and Pacific Islander (AANHPI) youth, in relation to other racial/ethnic groups in the United States. Data were obtained from the 2018 and 2019 Monitoring the Future surveys, which include a random, probability-based sample of youth in 8th, 10th, and 12th grades surveyed annually across the contiguous United States. Respondents provided information on race/ethnicity and e-cigarette use (n = 42,980). Measures of e-cigarette use included current (1 + of past 30 days) and regular use (10 + of past 30 days). Chi-square tests were used to determine differences in e-cigarette use by race/ethnicity. Associations between race/ethnicity, other sociodemographic factors, and e-cigarette use were explored using logistic regression analyses. Approximately 5.1% (n = 2,410) of the sample identified as AANHPI. A greater proportion of Native Hawaiian and Pacific Islanders reported current e-cigarette use (NHPI, 28.0%), relative to Asian American (AA, 10.3%), Black (9.5%), Hispanic or Latino (15.0%), American Indian or Alaskan Native (AIAN, 16.5%), multiracial (22.3%), and non-Hispanic White (25.2%) youth. Regular e-cigarette use was highest among non-Hispanic White (12.3%), followed by multiracial (10.7%), AIAN (7.8%), Hispanic or Latino (5.0%), AA (4.3%), and Black (3.0%) youth. Associations between race/ethnicity and e-cigarette use remained significant, after controlling for other sociodemographic factors. Continued monitoring of e-cigarette use is needed among AANHPI, a historically underrepresented population in tobacco research. Special attention should be paid to NHPI, who reported the highest rates of e-cigarette use.

Abstract
BACKGROUND With the aim of protecting minors, the World Health Organization has recommended classifying films with smoking scenes as unsuitable for children and adolescents. In recent years, films have increasingly been viewed via video streaming services - a trend which has been intensified by the COVID-19 pandemic - which poses new challenges for the protection of minors. AIM To examine the frequency of smoking scenes in Netflix feature films and the age recommendations for Netflix productions with smoking scenes. METHOD A total of 235 films that were made available for streaming exclusively by the Netflix platform in 2021 and 2022 were content coded in order to find out (1) how high the proportion of smoke-free films was in this film sample, (2) how often smoking scenes occurred in these films and (3) the proportion of films with smoke scenes classified as appropriate for young people in Germany and the USA. All films with an age rating of under 16 were considered suitable for children and young people. RESULTS Smoking scenes occurred in 113 of 235 analyzed films (48.1%). Of the 113 films with smoking scenes, 57 (50.4%) in Germany and 26 films (23.0%) in the USA were classified as youth films (p<0.001). A total of 3,310 smoking scenes were registered. Of these, 39.4% (n=1,303) were in films with youth ratings in Germany, and in Netflix USA this proportion was 15.8% (n=524). DISCUSSION Smoking scenes are a common feature in Netflix movies. Neither in the US nor in Germany does Netflix adhere to the recommendations of the WHO Framework Convention on Tobacco Control to restrict access by young people to films depicting smoking. However, the protection of minors in the US is better than in Germany, since half of the Netflix films with smoking scenes in Germany were rated as suitable for minors, in the USA less than a quarter.

Abstract
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.
