Stress, Dependence, and COVID-19-related Changes in Past 30-day Marijuana, Electronic Cigarette, and Cigarette Use among Youth and Young Adults

Associations Between U.S. High-School Student and Parental Job Loss During the COVID-19 Pandemic and Student Substance Use: Adolescent Behaviors and Experiences Survey (ABES), 2021

BACKGROUND

Job loss among both adults and adolescents increased markedly early in the COVID-19 pandemic. While parental job loss has been associated with the adverse effects, including adolescent substance use, no research is available on the effects of adolescent job loss on substance use.

METHODS

Analyses of Adolescent Behaviors and Experiences Survey (ABES) data from January to June 2021 were conducted to assess associations between parent and student pre-pandemic employment status and pandemic-era job loss and adolescent substance use behaviors. Cigarette, electronic vapor product (EVP), alcohol, and drug use were examined in a nationally representative sample of 7,705 U.S. high-school students.

RESULTS

Compared to students who did not lose their job during the pandemic, students reporting job loss had significantly elevated prevalences of current EVP use (29.9% vs. 19.7%), drinking more alcohol during the pandemic (25.3% vs. 16.7%), and current marijuana use (25.8% vs. 15.6%). Additionally, parental job loss was significantly associated with all substance use behaviors.

CONCLUSIONS

Higher levels of substance use associated with student and parental job loss, as well as parental unemployment, indicate that care may be needed for those students experiencing these losses. School-based intervention and prevention programs, including job loss supports for students, could be useful.

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.

Association of Perceived Stress, Social Support, and Self-Esteem with E-Cigarette Use Among U.S. College-Aged Young Adults

BACKGROUND

Given that college life is a major life-changing and stressful event for many young adults, they may use e-cigarettes to manage their stress, which in the long run could be detrimental to their health. Furthermore, perceived social support and self-esteem are important factors that might influence young adults' e-cigarette use behavior. This cross-sectional study examines the associations of perceived stress, social support, and self-esteem with e-cigarette use among U.S. college-aged young adults.

METHODS

Students (aged 18-24 years, n = 220) attending Slippery Rock University of Pennsylvania between February-May 2023 were recruited to complete an online survey. The outcome variables were current (past 30 days) and ever e-cigarette users, while the explanatory variables were perceived stress, perceived social support, self-esteem, and socio-demographics. Data was analyzed using bivariate and multivariable logistic regression models.

RESULTS

About 30.1% and 55.0% of participants were current users and ever users of e-cigarettes, respectively. Participants who perceived high stress (vs. low stress) were 12.4 (Adjusted Odds ratio (aOR) = 12.39, p = 0.02) and 7.4 (aOR = 7.37, p = 0.04) times more likely to be current users and ever users of e-cigarettes, respectively. For every one-unit increase in self-esteem score, the likelihood of participants being current e-cigarette users decreased by 7% (OR = 0.93, p = 0.01).

CONCLUSION

Perceived stress and self-esteem are significantly associated with e-cigarette use among college-aged young adults. Public health efforts should focus on stress reduction, healthy coping strategies, and improving self-esteem in order to prevent e-cigarette use among this population.

On the rise or a return to pre-pandemic levels? A cross-sectional online survey on nicotine, alcohol, and illicit drug use among youth

OBJECTIVES

The COVID-19 pandemic has had unprecedented and deteriorating effects on the mental health of adolescents and young adults. Various studies have described changes regarding substance abuse, but findings are conflicting.

STUDY DESIGN

We conducted a cross-sectional online survey on nicotine, alcohol, and illicit drug use.

METHODS

From March to May 2023, 502 participants aged 14-24 from a community-based sample completed the questionnaire.

RESULTS

We found a general trend of declining or stable substance use during the first 2 years of the pandemic; however, in the third year (i.e., 2022), substance use returned to pre-pandemic levels or exceeded it. Compared with young adults (age 19-24), adolescents' (age 14-18) use increased more clearly. Participants who scored above the cut-off on screening measures for problematic substance use showed a more pronounced increase in the use of cigarettes and illicit drugs but not of alcohol. Higher alcohol consumption during lockdowns was associated with increased likelihood of current problematic alcohol (odds ratio [OR]: 3.03) and cannabis use (OR: 2.60). Furthermore, individuals who reported increased usage of one psychotropic substance during lockdowns were more likely to have increased their use of other substances as well (OR: 2.66-4.87).

CONCLUSIONS

Although not optimally generalizable due to the retrospective online format and convenience sampling, our results support the notion that special attention ought to be paid to certain subgroups such as younger people and those who already exhibit problematic substance use during the pandemic. Following up on post-pandemic trends in substance use is crucial for developing prevention measures and targeted interventions.

Motivations for Tobacco, Cannabis, and Their Co-Use Among U.S. Young Adults Who Engage in Same-Day Co-Use

OBJECTIVES

The purpose of this study was to identify more detailed use behaviors and motivations for same-day co-use of tobacco and cannabis among U.S. young adults, compared to previous literature on co-use.

METHODS

We conducted an online cross-sectional survey among N = 303 U.S. young adults (ages 18-30, mean 25.9) during February 2024 through Prolific. The questions included co-use behaviors of tobacco and cannabis within the same day, and motivations for tobacco, cannabis, and their co-use. Using R, paired two-sample t-tests were used to compare mean differences of separate motivations to use measures for cannabis and tobacco among participants with same day co-use.

RESULTS

Among participants who reported past-30-day co-use of tobacco and cannabis (n = 176), a majority (94%; n = 160) reported same-day co-use. Participants who engaged in same-day co-use (n = 160) reported craving nicotine (60%), craving cannabis (54%), and feeling stressed (49%) as reasons for co-use. Among participants who engaged in same-day co-use, motivations for using cannabis (vs. tobacco) were higher for the level of effect, satisfying feeling, control over how much used, time to feel the effect, liking, purity, price, variety of product, amount to feel the effect, feeling less judged (p's < 0.024), and motivations for using tobacco (vs. cannabis) were higher for convenience, when feeling angry, and when feeling uncomfortable or upset (p's < 0.044).

CONCLUSIONS

Findings show that young adults may be co-using tobacco and cannabis on the same day due to cravings for both substances and stress and yet have different motivations for using cannabis and tobacco.

Cannabis vaping use in emerging adulthood: Characterizing transitions between stages of vaping among a diverse cohort in Texas

OBJECTIVE

To characterize and compare transitions in cannabis (THC) vaping by sociodemographic and other risk factors among a diverse cohort of youth and young adults observed between Spring 2019 and Fall 2021.

METHODS

We analyzed six (6) waves of panel data from n = 2605 youth transitioning into young adulthood via the Texas Adolescent Tobacco and Marketing Surveillance (TATAMS) system; participants provided N = 13,974 observations (i.e., completed surveys). The TATAMS sample was 37.7% Hispanic, 31.7% NH-White, 14.5% NH-Black, and 16.1% among NH-Other. We applied a three-state Markov model to estimate cannabis vaping initiation (never→ever), experimentation (never→current), escalation (ever→current), and de-escalation (current→ever). First, we compared transitions in THC vaping by race/ethnicity, with non-Hispanic (NH) Black as the referent. Second, we stratified the Markov models by race/ethnicity to identify common and unique predictors of cannabis vaping transitions, examining differences by: sex, age, alcohol use, depression (PHQ-9), anxiety (GAD-7) and nicotine vaping, across each race/ethnic category.

RESULTS

At baseline, 72.7% never vaped cannabis, 12.7% ever vaped cannabis, and 14.5% currently vaped cannabis. Across three years, risk for cannabis vaping experimentation (never → current) was significantly greater among NH-Blacks, relative to Hispanics (aHR: 1.89), NH-Whites (aHR: 2.27), and NH-Other (aHR: 2.01). Stratified models showed that current alcohol use was a common predictor of cannabis vaping experimentation among NH-White (aHR: 5.08), Hispanic (aHR: 2.32), and NH-Black (aHR: 2.91) participants. Depression predicted cannabis vaping initiation among Hispanics (aHR: 1.75) and experimentation among NH-Blacks (aHR: 3.95).

CONCLUSIONS

Onset of cannabis vaping during youth and young adulthood was most common among NH-Black youth, relative to other race/ethnic categories. Alcohol was a common predictor of cannabis vaping across race/ethnic categories while depression was linked to cannabis vaping transitions among Hispanic and NH-Black youth, only. Future research should investigate the link between alcohol use, mental health, and cannabis vaping among young people.

Hunger and housing: Economic disparities in current and daily tobacco use among high school students in the United States in 2021

Introduction

Economic disparities in tobacco use and dependence are well-documented among adults but not adolescents. This study aims to examine economic disparities in patterns of tobacco use among a nationally representative sample of high school students in Spring 2021.

Methods

We analyzed data from n = 6750 US high school student via the 2021 Adolescent Behaviors and Experiences Survey (ABES). We estimated the association between experiencing homelessness and food insecurity (analyzed independently) and current (past 30-day) and daily (all 30 days) use of four tobacco products (e-cigarettes; cigarettes; cigars; smokeless). Models controlled for sex, race/ethnicity, age, and sexual identity.

Results

Overall, ∼1.8 % experienced homelessness and 23.7 % experienced food insecurity. Experiencing homeless was significantly associated with greater odds of current use for e-cigarette (aOR: 3.43), cigarettes (aOR: 5.58), cigars (aOR: 10.47), and smokeless tobacco (aOR: 4.41) as well as greater risk for daily use of e-cigarettes (aOR: 2.66), cigarettes (aOR: 10.94), and cigars (aOR: 5.23) but not smokeless tobacco (aOR: 2.48; 95 %CI: 0.51-12.16). Food insecurity was significantly associated with greater odds of current use of e-cigarettes (aOR: 2.00), cigarettes (aOR: 2.15), and cigars (aOR: 2.44) but not smokeless (aOR: 1.04; 95 % CI: 0.56-1.93). No association was observed between food insecurity and daily tobacco use.

Conclusion

Substantial economic disparities in tobacco use were observed in a nationally representative sample of high school students. Interventions should consider prioritizing economic determinants of health during adolescence, including a focus on preventing youth tobacco use as well as addressing upstream determinants of homelessness and food insecurity.

Serious psychological distress and higher associations with tobacco and cannabis use among college students in the United States

OBJECTIVE

To examine associations between serious psychological distress (SPD) and tobacco and cannabis use among college students in the United States.

METHODS

This cross-sectional study included 257,626 college students from the 2019-2022 National College Health Assessment survey. SPD was defined as having symptoms in the past month. Current tobacco (i.e., cigarettes, e-cigarettes) and cannabis use was defined as past month use. Multiple product use was categorized for single, dual, or triple products. Adjusted logistic regression models were used to examine associations between SPD, tobacco, cannabis, and multiple product use.

RESULTS

SPD increased over time (18.4% to 23.8%) among students and nearly 30% of tobacco or cannabis users reported SPD. Cigarette, e-cigarette, or cannabis use was associated with about a 50-60% increased likelihood of reporting SPD than non-current use of each product, with the highest associations in Fall 2020. Triple product users had double the likelihood of reporting SPD, followed by dual users at 70% and single users at 47%, relative to non-current users. Daily users also had nearly twice the likelihood of reporting SPD, followed by non-daily users at 13-35%, relative to non-current users.

CONCLUSIONS

College students have an increasing burden of SPD which is significantly associated with tobacco and cannabis use. There is a dose-response relationship between the number of tobacco and cannabis products used, as well as the frequency of use, and SPD among U.S. college students. Colleges addressing student mental health should prioritize the implementation of screening and treatment support for tobacco, cannabis, and multiple product use.

Cannabis use among adolescents and young adults during the COVID-19 pandemic: A systematic review

Background

A systematic review of the literature was performed to summarize cannabis use among adolescents and young adults during the COVID-19 pandemic. Special focus was given to the prevalence of cannabis use during COVID-19, as well as factors that may explain changes in cannabis consumption patterns.

Methods

The protocol of this systematic review was registered. Articles from seven publication databases were searched in January 2022. The inclusion criteria for studies were as follows: 1) published in English; 2) study instruments needed to include items on COVID-19; 3) conducted after January 1st, 2020; 4) published in a peer-reviewed journal, dissertation, or thesis; 5) study population ≤25 years of age; 6) study designs were limited to observational analytical studies; 7) measured cannabis use. This review excluded other reviews, editorials, and conference abstracts that were not available as full text manuscripts. Independent review, risk of bias assessment, and data abstraction were performed by two authors.

Results

Fifteen articles from the United States (n=11) and Canada (n=4) were included in this review. The findings of this review showed that the prevalence of cannabis use during the pandemic among adolescents and young adults were mixed. Some mental health symptoms, including depression and anxiety, were identified as the most commonly reported reasons for increased cannabis use during the pandemic.

Conclusions

This review highlights the inconsistencies in the prevalence of cannabis use among adolescents and young adults during the pandemic. Therapeutic interventions for mental health and continued public health surveillance should be conducted to understand the long-term effects of cannabis use among adolescents and young adults.

Immigration status-related exclusive e-cigarette use and cannabis use and their dual use disparities associated with mental health disorder symptoms

INTRODUCTION

E-cigarette and cannabis use has been linked to various health risks, including respiratory and cardiovascular conditions. Yet, extant knowledge about the risk factors for exclusive and dual use of e-cigarettes and cannabis is limited, especially among immigrants. We examined exclusive e-cigarette and cannabis use and their dual use associated with mental health disorders among immigrants and U.S.-born.

METHODS

We analyzed national cross-sectional data collected between May 13, 2021, and January 9, 2022, among adults aged >18 years (n= 4766) living in U.S. Multinomial logistic regression analyses were conducted to model the associations of exclusivity and dual-use (reference group= non-use) with anxiety/depression.

RESULTS

The dual-use prevalence was higher than exclusive e-cigarette and cannabis use, especially among U.S.-born (dual use= 14.79% vs. cannabis use= 13.53% vs. e-cigarette use= 7.11%) compared to immigrants (dual use= 8.23% vs. cannabis use= 5.03% vs. e-cigarette use= 6.31%). Immigrants had lower risks of exclusive cannabis and dual use compared to U.S.-born. Anxiety/depression was associated with higher risks of exclusive cannabis use and dual use across immigration status, but was associated with exclusive e-cigarette use among only immigrants. While effect sizes of dual-use associated with anxiety/depression were higher among U.S.-born, the effect sizes of exclusive e-cigarette and cannabis use associated with anxiety/depression were higher among immigrants.

CONCLUSIONS

The findings revealed significant mental health risks for e-cigarette, cannabis, and their dual use among immigrants and U.S.-born, especially among U.S.-born. These findings highlight the need for public health research and interventions to consider immigration status-related disparities in substance use.

Anxiety as a predictor of the age of initiation of tobacco and cannabis use in adolescents and young adults

BACKGROUND

Previous research has shown important links between anxiety and the use of tobacco and cannabis. However, it remains unclear whether anxiety leads youth to start using tobacco and cannabis at an earlier age.

METHODS

Data were drawn from Texas Adolescent Tobacco and Marketing Surveillance System for the years 2019-2021(Waves 9-14). Participants were in 10th-grade, 12th-grade, and two years post-high school at baseline. The outcomes were the age of first use of cigarettes, e-cigarettes, and cannabis. Interval-censoring Cox proportional hazards models were fit to examine the differences in the estimated age of initiation of tobacco and cannabis use by anxiety.

RESULTS

Among the 10th-grade cohort, participants with anxiety had an increased risk of an earlier age of cigarette [AHR = 2.29(1.63-3.23)], e-cigarette [AHR = 1.53(1.17-2.00)], and cannabis [AHR = 1.59(1.23-2.05)] initiation. Among the 12th-grade cohort, participants with anxiety had an increased risk of an earlier age of cigarette [AHR = 1.52(1.21-1.90), e-cigarette [1.25(1.01-1.60)] and cannabis [AHR = 1.35(1.09-1.67] initiation. Among the post-high school cohort, the only significant association found was for cannabis initiation [AHR = 1.33(1.11-1.58). Between ages 18-to-19 years in the 10th-grade cohort, and between ages 20-21 years in the 12th-grade cohort, cumulative incidence of each of the three outcomes initiation doubled among anxious youth.

CONCLUSIONS

This study's findings show that anxiety symptoms can increase the risk of substance use initiation at an earlier age, especially among the youngest adolescent cohort (∼15-to-16-year-olds). These findings highlight the importance of early screening and treatment of anxiety symptoms as a preventive measure to delay or prevent the onset of substance use initiation.

Youth perception of difficulty accessing cannabis following cannabis legalization and during the early and ongoing stages of the COVID-19 pandemic: repeat cross-sectional and longitudinal data from the COMPASS study

BACKGROUND

Very little research has examined how perceptions of cannabis access among underage youth in Canada have changed since cannabis was legalized and since the onset of the COVID-19 pandemic. As such, this paper examines the effect of the early and ongoing stages of the COVID-19 pandemic period on youth perceptions of cannabis access over time since the onset of the Cannabis Act in 2018 in a large sample of Canadian youth.

METHODS

Using data from the COMPASS study (T1:2018/19, T2:2019/20, T3:2020/21), we used both repeat cross-sectional data [T1 (n = 38,890), T2 (n = 24,109), and T3 (n = 22,795)] to examine overall trends in perceptions of cannabis access, and sequential cohort longitudinal data [n = 4,677 students linked from T1 to T3] to examine the differential changes in perceptions of cannabis access among students over time.

RESULTS

In the cross-sectional sample, the frequency of students reporting that cannabis was easy to access decreased by 26.7% from T1 (51.0%) to T3 (37.4%), although respondents who have used cannabis were more likely to report access was easy. In the longitudinal sample, perceptions of cannabis access being easy increased over time, especially among cannabis users. Perceived ease of access appears to have been slightly impeded during the initial pandemic period but rebounded during the ongoing pandemic period.

CONCLUSIONS

While the prevalence of youth reporting that cannabis is easy to access has declined since legalization and throughout the early and ongoing pandemic periods, a substantial number of underage youth continue to report that cannabis is easy to access. This suggest that there is an ongoing need for continued cannabis control efforts to address this issue.

[Impact of the COVID-19 pandemic on cannabis use in young adults and general population: a systematic review]

OBJECTIVE

The first COVID-19 lockdown was a very restrictive situation that may have impacted on the prevalence and patterns of cannabis use. The aim of this systematic review was to assess the evidence on cannabis use and reasons for use in different countries during first lockdown in young adults and general population.

METHODS

This study followed PRISMA guidelines, and the review protocol was registered in PROSPERO (registration CRD42022303181). The search was carried out in PubMed, Scopus, Web of Science y Embase databases. Inclusion criteria were: cross-sectional or cohort studies; population ≥16 years; exploring cannabis use during lockdown; and English or Spanish language.

RESULTS

Thirty studies, conducted in European countries (n=17), North America (n=12) and rest of the world (n=1), were analysed. The overall prevalence of cannabis use was found to be largely unchanged, but regular users tended to maintain (between 39.5% and 96.8% of the sample) or increase cannabis use (between 2.9% and 51.6%). The main decreases were among occasional users. Some reasons for the increase were boredom, loneliness, stress, coping and depressive symptoms. In addition, young people were the heaviest users, and being younger, live without family, financial problems and a low educational level were significantly (p-value<0.05) associated with increased use.

CONCLUSIONS

Most regular users maintained or slightly increased their use, with young people being the main users. Concerning reasons for use like coping and depressive symptoms were found. Cannabis use needs to be addressed with strategies focused on the young population, considering occasional and regular use, as well as motivations.

Changes in self-reported cannabis use during the COVID-19 pandemic: a scoping review

BACKGROUND

The COVID-19 pandemic is affecting mental health and substance use (MHSU) issues worldwide. The purpose of this study was to characterize the literature on changes in cannabis use during the pandemic and the factors associated with such changes.

METHODS

We conducted a scoping review by searching peer-reviewed databases and grey literature from January 2020 to May 2022 using the Arksey and O'Malley Framework. Two independent reviewers screened a total of 4235 documents. We extracted data from 129 documents onto a data extraction form and collated results using content analytical techniques.

RESULTS

Nearly half (48%) of the studies reported an increase/initiation of cannabis use, while 36% studies reported no change, and 16% reported a decrease/cessation of cannabis use during the pandemic. Factors associated with increased cannabis use included socio-demographic factors (e.g., younger age), health related factors (e.g., increased symptom burden), MHSU factors (e.g., anxiety, depression), pandemic-specific reactions (e.g., stress, boredom, social isolation), cannabis-related factors (e.g., dependence), and policy-related factors (e.g., legalization of medical/recreational cannabis).

CONCLUSION

Public health emergencies like the COVID-19 pandemic have the potential to significantly impact cannabis use. The pandemic has placed urgency on improving coping mechanisms and supports that help populations adapt to major and sudden life changes. To better prepare health care systems for future pandemics, wide-reaching education on how pandemic-related change impacts cannabis use is needed.

Factors associated with Korean adolescent's e-cigarette use by the severity level of generalized anxiety disorder (GAD-7)

BACKGROUND

The use of e-cigarette among Korean adolescents is spreading with alarming rapidity, but it has not been studied along with the severity level of GAD-7. This study aims to identify adolescents' e-cigarette use and its associated factors among four different anxiety groups using the problem behavioral theory (PBT).

METHODS

A cross-sectional secondary dataset was retrieved from the 2020 Korea Youth Risk Behavior Survey. Of the total sample of 54,948, four anxiety groups were formed: minimal (score 0-4; n = 36,711), mild (score 5-9; n = 12,138), moderate (score 10-14; n = 4143), and severe (score above 15; n = 1965). A total of 11 variables were selected based on the PBT domains. Descriptive analysis, Chi-square, ANOVA, univariate analysis, and multiple linear regression analysis were performed.

RESULTS

E-cigarette use was the highest in the order of severe, mild, moderate, and minimal. While cigarette use was associated with vaping in all anxiety groups, adolescents with minimal or mild anxiety levels were more likely to be influenced by tobacco accessibility and other behavior system factors such as sexual intercourse, alcohol use, and smartphone addiction. Meanwhile, secondhand smoke exposure in public areas was only associated with those with severe anxiety levels, and secondhand smoke exposure at school was a significant factor in all anxiety groups except for those with moderate anxiety levels.

LIMITATION

Due to the nature of cross-sectional dataset, the study could not draw causal links between vaping and other identified factors, include all the necessary PBT components.

CONCLUSION

These findings underscore the need to consider different levels of anxiety when addressing the problems related to vaping among Korean adolescents.

Associations over the COVID-19 pandemic period and the mental health and substance use of youth not in employment, education or training in Ontario, Canada: a longitudinal, cohort study

BACKGROUND

The economic shutdown and school closures associated with the COVID-19 pandemic have negatively influenced many young people's educational and training opportunities, leading to an increase in youth not in education, employment, or training (NEET) globally and in Canada. NEET youth have a greater vulnerability to mental health and substance use problems, compared to their counterparts who are in school and/or employed. There is limited evidence on the association between COVID-19 and NEET youth. The objectives of this exploratory study included investigating: longitudinal associations between the COVID-19 pandemic and the mental health and substance use (MHSU) of NEET youth; and MHSU among subgroups of NEET and non-NEET youth.

METHODS

618 youth (14-28 years old) participated in this longitudinal, cohort study. Youth were recruited from four pre-existing studies at the Centre for Addiction and Mental Health. Data on MHSU were collected across 11 time points during the COVID-19 pandemic (April 2020-August 2022). MHSU were measured using the CoRonavIruS Health Impact Survey Youth Self-Report, the Global Appraisal of Individual Needs Short Screener, and the PTSD Checklist for DSM-5. Linear Mixed Models and Generalized Estimating Equations were used to analyze associations of NEET status and time on mental health and substance use. Exploratory analyses were conducted to investigate interactions between sociodemographic characteristics and NEET status and time.

RESULTS

At baseline, NEET youth were significantly more likely to screen positive for an internalizing disorder compared to non-NEET youth (OR = 1.92; 95%CI=[1.26-2.91] p = 0.002). No significant differences were found between youth with, and without, NEET in MHSU symptoms across the study time frame. Youth who had significantly higher odds of screening positive for an internalizing disorder included younger youth (OR = 1.06, 95%CI=[1.00-1.11]); youth who identify as Trans, non-binary or gender diverse (OR = 8.33, 95%CI=[4.17-16.17]); and those living in urban areas (OR = 1.35, 95%CI=[1.03-1.76]), compared to their counterparts. Youth who identify as White had significantly higher odds of screening positive for substance use problems (OR = 2.38, 95%CI=[1.72-3.23]) compared to racialized youth.

CONCLUSIONS

Our findings indicate that sociodemographic factors such as age, gender identity, ethnicity and area of residence impacted youth MHSU symptoms over the course of the study and during the pandemic. Overall, NEET status was not consistently associated with MHSU symptoms over and above these factors. The study contributes to evidence on MHSU symptoms of NEET youth.

"There must be something good": Fair balance and ad appeal of marijuana brands' website

Ever since medical and nonmedical marijuana became legal in parts of the United States in 2012, scholars have cited concerns regarding marijuana advertising's impact on adolescents. The current study aimed to explore how online marijuana websites are utilizing their advertising strategies amid the lack of centralized regulation by qualitatively analyzing 141 websites of marijuana brands in the United States. We found that the common themes they employed were high, professionalism, natural, and adventurous. There was no fair balance between benefit and risk information because most of the brands did not communicate the risk. The use of animated characters was found, along with other appeals that could potentially influence underage users. Areas of concern that need imminent attention from the regulatory body are discussed.

Dopamine D1-like receptor activation decreases nicotine intake in rats with short or long access to nicotine

The use of nicotine and tobacco products is highly addictive. The dopaminergic system plays a key role in the initiation and maintenance of nicotine intake. Dopamine D1-like receptor blockade diminishes nicotine intake in rats with daily short (1 h) access to nicotine, but little is known about the effects of dopamine receptor antagonists or agonists on nicotine intake in rats with intermittent long (23 h) access. Because of the extended access conditions and high nicotine intake, the intermittent long access procedure might model smoking and vaping better than short access models. We investigated the effects of the dopamine D1-like receptor antagonist SCH 23390 and the D1-like receptor agonist A77636 on nicotine intake in male rats with intermittent short or long access to nicotine. The rats self-administered nicotine for 5 days (1 h/day) and were then given 15 intermittent short (1 h/day) or long (23 h/day) access sessions (3 sessions/week, 0.06 mg/kg/inf). The D1-like receptor antagonist SCH 23390 decreased nicotine intake to a similar degree in rats with short or long access to nicotine. The D1-like receptor agonist A77636 induced a greater decrease in nicotine intake in the rats with long access to nicotine than in rats with short access. Treatment with A77636 induced a prolonged decrease in nicotine intake that lasted throughout the dark and light phase in the long access rats. These findings indicate that blockade and stimulation of D1-like receptors decrease nicotine intake in an intermittent long access animal model that closely models human smoking and vaping.

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.

Risk perceptions and changes in tobacco use in relation to Coronavirus Disease 2019 pandemic: A qualitative study on adolescent tobacco users in Hong Kong

INTRODUCTION

Tobacco use is associated with an increased risk of Coronavirus Disease 2019 (COVID-19) infection, severe COVID-19 outcomes requiring intensive care, and mortality. We investigated the perceived risk of and changes in cigarette, e-cigarette (EC) and heated tobacco product (HTP) use in relation to COVID-19 in Hong Kong adolescent tobacco users.

METHODS

We conducted semi-structured telephone interviews from January to April 2021 and in February 2022 on 40 adolescents (65% boys, Secondary school grades 2-6) who participated in our previous smoking surveys and were using cigarettes, ECs or HTPs before the first wave of the COVID-19 pandemic in January 2020.

RESULTS

Adolescents generally perceived higher risks of contracting and having more severe COVID-19 from using cigarettes than ECs/HTPs, but they had limited knowledge of COVID-19 risks from EC/HTP use, particularly. Both increased and reduced consumption were found in tobacco, with EC use being the less affected product. Changes also included switching to ECs for convenience and lower cost and shifting from smoking cigarettes outside to mainly at home or in hidden areas. COVID-related policies, fear of infection, non-COVID-related health concerns, less social opportunities and pocket money, and limited access to tobacco products were barriers to tobacco use. In contrast, greater freedom at home versus school and negative emotions due to social distancing were facilitators. Family/peer influence had mixed impacts.

CONCLUSIONS

Adolescent tobacco users perceived lower COVID risks associated with HTPs and ECs than cigarettes, and various changes in tobacco use were found amid the pandemic in Hong Kong. COVID-19 and related social changes may both facilitate or deter adolescent tobacco use.

The Association Between Tobacco and Cannabis Use and the Age of Onset of Depression and Anxiety Symptoms: Among Adolescents and Young Adults

INTRODUCTION

No studies have prospectively explored the association between the use of tobacco or cannabis use and the age of onset of depressive or anxiety symptoms, and no studies have identified the peak ages and ranges of onset of these symptoms among tobacco and/or cannabis users.

AIMS AND METHODS

This is a secondary analysis of Texas Adolescent Tobacco and Marketing Surveillance System data, waves 9-14 (2019-20121). Participants were in 10th grade, 12th grade, and 2 years post-high school (HS) at baseline (wave 9). Interval-censoring multivariable Cox proportional hazards models were fit to assess differences in the estimated age of onset of depression and anxiety by tobacco and cannabis use while adjusting for covariates.

RESULTS

We found that lifetime or ever cigarette, e-cigarette, and cannabis use had an increased risk of an earlier age of onset of depressive and anxiety symptoms across the three cohorts, and the youngest cohort was the most differentially impacted by substance use. Between ages 18 to 19 years in the 10th-grade cohort, between ages 20 to 21 years in the 12th-grade cohort, and between ages 22 to 23 years in the post-HS cohort, the estimated hazard function (or cumulative incidence) for reporting depressive and anxiety symptoms almost doubled among lifetime cigarette, e-cigarette, and cannabis users.

CONCLUSIONS

Tobacco and cannabis users should be screened for mental health problems at an earlier age, especially those aged 18 years and younger, and provided with age- and culturally appropriate resources to prevent or delay the onset of anxiety and/or depression symptoms.

IMPLICATIONS

The study's findings indicate that tobacco and cannabis use is directly linked to the early onset of depressive and anxiety symptoms among youth. This highlights the significance of early screening and substance use interventions, particularly for youth aged 18 years and younger, as they are disproportionately affected by both substance use and mental health problems. School-based interventions that are age- and culturally appropriate hold promise as they enable youth to seek professional help early, and in a supportive environment. Intervening early in substance shows promise in reducing the likelihood of developing mental health problems at a young age.

COVID-19 Vaccine Uptake and Attitudes Within Two Cohorts of Younger Adult Cannabis Users

It is crucial to understand COVID-19 vaccine uptake and attitudes among young adult cannabis users given the lowest vaccination rates among young adults and negative association between cannabis use and willingness to get vaccinated. 18-21-year-old and 26-33-year-old cohorts of cannabis users, recruited in California, were surveyed about the COVID-19 vaccine uptake/attitudes between March-August 2021. Cannabis use/demographic differences were investigated by vaccination status. Vaccine attitudes data were categorized and presented descriptively. 44.4% of the older and 71.8% of the younger cohorts were vaccinated. Non-Hispanic Black/African American race/ethnicity, lack of health insurance, and medicinal orientation towards cannabis use were negatively associated with vaccine receipt within the older cohort. For both cohorts, top reasons for vaccine hesitancy and rejection were concerns about speed of development, potential side effects, natural immunity, and lack of trust of vaccines. Our results highlight greater vaccine hesitance/rejection and need for targeted interventions among mid-20's-early-30's cannabis users.

The Association of Global and Disease-Related Stress With Susceptibility to and Use of E-Cigarettes and Marijuana Among Adolescents With Congenital Heart Disease

OBJECTIVE

Adolescents with congenital heart disease (CHD) are exposed to disease-related stressors and have elevated risk for cardiovascular and cognitive complications that are exacerbated by e-cigarettes and marijuana. The aims of this cross-sectional study are to: (1) identify the association between perceived global and disease-related stress and susceptibility to e-cigarettes and marijuana, (2) determine if the association between stress and susceptibility differs by gender, and (3) explore the association between stress and ever use of e-cigarettes and marijuana among adolescents with CHD.

METHODS

Adolescents with CHD (N = 98; aged 12-18 years) completed self-report measures of susceptibility to/ever use of e-cigarettes and marijuana and global and disease-related stress.

RESULTS

Susceptibility to e-cigarettes and marijuana was reported by 31.3% and 40.2% of adolescents, respectively. Ever use of e-cigarettes and marijuana was reported by 15.3% and 14.3% of adolescents, respectively. Global stress was associated with susceptibility to and ever use of e-cigarettes and marijuana. Disease-related stress was associated with susceptibility to marijuana. Females reported more global and disease-related stress than males, but the association of stress with susceptibility to e-cigarettes and marijuana did not differ by gender.

CONCLUSIONS

Susceptibility to e-cigarettes and marijuana is common among adolescents with CHD and is associated with stress. Future work to examine the longitudinal associations between susceptibility, stress, and use of e-cigarettes and marijuana is warranted. Global stress may be an important consideration in the development of strategies to prevent these risky health behaviors among adolescents with CHD.

Risk Factors Associated With Driving After Marijuana Use Among US College Students During the COVID-19 Pandemic

PURPOSE

To assess the sociodemographic and behavioral risk factors associated with driving after marijuana use among US college students.

METHODS

A secondary analysis used the fall 2020 and spring 2021 American College Health Association- National College Health Assessment III and the dataset was restricted to college students ≥18 years of age who reported recent driving and marijuana use. Associations between risk factors and driving after marijuana use were estimated using multivariable logistic regression.

RESULTS

A total of 29.9% (n = 4,947) of the respondents reported driving after marijuana use. Males (adjusted odds ratio [AOR]: 1.64, 95% confidence interval [CI]: 1.48-1.82), non-Hispanic Black (AOR: 1.32, 95% CI: 1.02-1.71), sexual minorities (AOR: 1.19, 95% CI: 1.07-1.31), individuals with an alcohol or substance use disorder (AOR: 1.44, 95% CI: 1.08-1.91), anxiety (AOR: 1.20, 95% CI: 1.06-1.36), higher suicidality (AOR: 1.18, 95% CI: 1.07-1.31), and those who also drank and drove (AOR: 3.18, 95% CI: 2.84-3.57) had a higher risk of driving after marijuana use.

DISCUSSION

Future research should focus on increasing awareness of driving after marijuana use and prevention programs and/or strategies on college campuses regarding driving after marijuana use for these groups to reduce this risky behavior.

Neighborhood Characteristics and the Burden of E-Cigarette, or Vaping, Product Use-Associated Lung Injury: An Ecological Comparison Study

Purpose: E-cigarette, or vaping, product use-associated lung injury (EVALI) is a severe consequence of vaping first described in 2019. Investigating associations between neighborhood-level characteristics and EVALI cases is an important step in identifying at-risk communities to implement future targeted prevention programs. Methods: We retrospectively identified 41 adolescents <19 years hospitalized for treatment for EVALI at Children's Medical Center Dallas from December 2018 to June 2021. Patient ZIP codes were extracted from the electronic medical record and were compared with Dallas area ZIP codes containing no EVALI cases. Socioeconomic status (SES) characteristics were obtained from the 2019 American Community Survey, and they were mapped for ZIP codes using ESRI ArcMap geospatial processing software. A parallel analysis was conducted utilizing data of adolescents hospitalized with appendicitis. Results: Ninety-five percent of our cohort used tetrahydrocannabinol-containing products, and 66% obtained their vaping products from informal sources. EVALI cases were less likely to reside in higher SES ZIP codes as measured by the proportion of the population with at least a high school education (odds ratio [OR]: 0.95, 95% confidence interval [CI]: 0.92-0.99), access to broadband access (OR: 0.95, 95% CI: 0.91-0.99), and private health insurance (OR: 0.97, 95% CI: 0.95-0.99). Alternatively, they were more likely to reside in lower SES ZIP codes as measured by proportion of the population without any health insurance (OR: 1.07, 95% CI: 1.01-1.12). No neighborhood level low SES characteristics were associated with appendicitis hospitalizations. Conclusions: Although small in magnitude, EVALI cases were associated with lower SES ZIP codes but not with vape shop density.

Patterns in Mental Health Symptomatology and Cigarette, E-cigarette, and Marijuana Use Among Texas Youth and Young Adults Amid the Coronavirus Disease 2019 Pandemic

INTRODUCTION

This study examined patterns in mental health symptomatology and smoking and vaping behaviors among youth and young adults over a 1-year period from before to during the first year of the Coronavirus Disease 2019 (COVID-19) pandemic.

AIMS AND METHODS

Participants (n = 2148) were 16-24-year-olds who completed three waves of the Texas Adolescent Tobacco and Marketing Surveillance Study (TATAMS). Descriptive statistics and mixed effects logistic regression models were used to examine changes in anxiety symptoms, depressive symptoms, perceived stress, and cigarette, e-cigarette, and marijuana use from before COVID-19 (fall 2019) to 6-month follow-up (spring 2020) and 12-month follow-up (fall 2020) periods during COVID-19. Longitudinal associations between mental health symptomatology and smoking and vaping were examined.

RESULTS

Modest increases in symptoms of anxiety and depression were observed from before to during COVID-19. Perceived stress remained high and unchanged. Ever marijuana use increased at 6- and 12-month follow-up, while ever cigarette and e-cigarette use increased significantly only at 12-month follow-up. Marijuana use frequency increased significantly at 6- and 12-month follow-ups. Adjusting for sociodemographic factors, increased symptoms of anxiety and depression predicted increases in ever cigarette, e-cigarette, and marijuana use, and past 30-day cigarette and e-cigarette use, but not past 30-day marijuana use. Higher perceived stress predicted increases in ever use of cigarettes and e-cigarettes and past 30-day cigarette use.

CONCLUSIONS

Changes in mental health symptomatology and smoking and vaping behaviors among young people in Texas varied during this period of the COVID era. Increases in mental health symptomatology predicted increases in cigarette, e-cigarette, and marijuana use behaviors.

IMPLICATIONS

This study adds to the limited research on the longitudinal impact of anxiety symptoms, depressive symptoms, and perceived stress on cigarette, e-cigarette, and marijuana use from before to during the first year of the COVID-19 pandemic. Findings warrant health messaging and interventions that address the significant impact of worse mental health on increased smoking and vaping behavior, especially during crises like COVID-19 that may exacerbate mental health and substance use behaviors.

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.

Impact of the COVID-19 Pandemic on the Evolution of Prevalence and Patterns of Cannabis Use among First-Year University Students in Spain-UniHcos Project

Among university students there has been evidence that the COVID-19 pandemic increased their psychological distress, exacerbated by social restrictions. The main objective of this study was to explore the impact of the COVID-19 pandemic on the prevalence and patterns of cannabis use among university students, in contrast to previous trends since 2012. Data from 10,522 first-year university students (73.3% female, Mage 19 (SD = 1.6)) from eleven Spanish universities collected between 2012 and May 2022 was analysed. Prevalences of cannabis use and their differences by sex were studied, as well as changes in patterns of use and its use for coping during the pandemic. It was found that during lockdown, all prevalence rates of cannabis use decreased in both sexes, showing no statistically significant differences and increasing again in the new normal period in both. Among regular cannabis users, 79.7% reported maintaining or increasing their cannabis use during the pandemic, and of these, half reported using cannabis to cope. Moreover, cannabis use in the usual household increased during the lockdown. These results show that although the overall prevalence of cannabis use was reduced during the lockdown, regular users tended to maintain or increase cannabis use. This could imply two different patterns of use among students, one social and occasional versus the other regular, providing new lines of research for prevention and the implementation of social policies.

Dopamine D1-like receptor blockade and stimulation decreases operant responding for nicotine and food in male and female rats

Dopamine has been implicated in the reinforcing effects of smoking. However, there remains a need for a better understanding of the effects of dopamine D1-like receptor agonists on nicotine intake and the role of sex differences in the effects of dopaminergic drugs on behavior. This work studied the effects of D1-like receptor stimulation and blockade on operant responding for nicotine and food and locomotor activity in male and female rats. The effects of the D1-like receptor antagonist SCH 23390 (0.003, 0.01, 0.03 mg/kg) and the D1-like receptor agonist A77636 (0.1, 0.3, 1 mg/kg) on responding for nicotine and food, and locomotor activity were investigated. The effects of SCH 23390 were investigated 15 min and 24 h after treatment, and the effects of the long-acting drug A77636 were investigated 15 min, 24 h, and 48 h after treatment. Operant responding for nicotine and food and locomotor activity were decreased immediately after treatment with SCH 23390. Treatment with SCH 23390 did not have any long-term effects. Operant responding for nicotine was still decreased 48 h after treatment with A77636, and food responding was decreased up to 24 h after treatment. Treatment with A77636 only decreased locomotor activity at the 48 h time point. There were no sex differences in the effects of SCH 23390 or A77636. In conclusion, the D1-like receptor antagonist SCH 23390 reduces nicotine intake and causes sedation in rats. Stimulation of D1-like receptors with A77636 decreases nicotine intake at time points that the drug does not cause sedation.

Associations Between Covid-19-Related Threat, Stress, and Smoking in UK Adults Aged Under- and Over-30

It has been suggested that smoking and age are associated with higher vulnerability to Covid-19. While threat of Covid-19 may reduce or stop smoking, increased stress due to lockdown could increase smoking behaviour. This study aimed to investigate changes in smoking behaviour in relation to age, Covid-19-related threat and subjective perceived stress during the UK lockdown. A cross-sectional study was performed. Online adverts were used to recruit UK residents who smoked combustible tobacco any time from January 2020. A questionnaire measured demographic information, smoking behaviour pre- and during-lockdown, perceived subjective stress (PSS), and Covid-19 related threat. Data were collected from a total of 145 participants (58% women, 39% men, 3% non-binary; mean age: 26 years, SD = 7.7), during UK lockdown between 22nd May and 22nd June 2020. Independent of stress and Covid-19-related threat, smoking was reduced in those aged less than 30 years. In participants aged 30 and above, increases in smoking behaviour were associated with higher PSS. The results highlight the relevance of the different stages of life on the relationship between stress, threat, and smoking behaviour. Greater emphasis should be placed on stress reduction for adult smokers aged 30 and above to enable smoking cessation.

E-cigarette use and intentions related to psychological distress among cigarette, e-cigarette, and cannabis vape users during the start of the COVID-19 pandemic

Background

This study examines associations between psychological distress, intentions to use e-cigarettes, and cigarette smoking, e-cigarette use, and cannabis consumption through e-cigarette use among a diverse sample of U.S. young adults.

Procedures

Young adults (N = 314; 72.5% female) were recruited to complete an online survey during the first few months of the COVID-19 pandemic.

Results

Associations between psychological distress and cigarette smoking, e-cigarette use, cannabis vaping, and intentions to use e-cigarettes were found. Current e-cigarette use (OR = 1.23, 95% CI 1.17, 1.28, p < .001; 7.5%) and cannabis vaping (OR = 2.03, 95% CI 1.88, 2.18, p < .001; 10%) was higher among female, possibly due to the significantly higher psychological distress reported among females. Interactions between intentions to use e-cigarettes and psychological distress variables were found for all smoking and vaping behaviors.

Conclusions

Public health efforts should increase focus on providing psychological services for young adults to improve coping strategies that are alternative to smoking and vaping behaviors.

Young Adult E-Cigarette and Combustible Tobacco Users Attitudes, Substance Use Behaviors, Mental Health, and Neurocognitive Performance

Nicotine and tobacco product (NTP) use has escalated, largely due to the advent of e-cigarettes. The NTP administration method (i.e., combustible cigarette, e-cigarette) may be an important differentiator. We assessed young adult substance use history, nicotine attitudes, mental health, and neurocognition by the NTP use method. Emerging adults (16–22 year olds) were divided into combustible NTP users (Combustible+ = 79, had used any combustible NTP in the last 6 months), non-combustible users (E-Cig = 43, had used non-combustible NTP, in the past 6 months), and NTP Naïve (n = 79; had not used NTP in the past 6 months) based on past 6-month NTP use patterns. Participants completed self-report and objective neurocognition measures. Analysis of covariance assessed mental health and neurocognition by group, controlling for confounds and correcting for multiple comparisons. Nicotine groups reported more favorable attitudes toward combustible cigarette and e-cigarette use, with taste as the primary reason for e-cigarette use. Combustible+ reported more nicotine dependence and craving. Substance use differed by group, with Combustible+ using the most NTP, alcohol, and cannabis. Nicotine groups reported higher depression and stress symptoms; male Combustible+ reported higher depression symptoms than other same-gender groups. Groups did not differ on neurocognition, though cannabis use was associated with inaccurate emotional Stroop responses. Overall, research suggests that young adult combustible users are likely qualitatively different from non-combustible users. Understanding the unique characteristics related to NTP product use will help guide intervention and prevention development.

Perceived stress and E-cigarette use during emerging adulthood: A longitudinal examination of initiation, progression, and continuation

E-cigarettes are the most commonly used tobacco product among youth and young adults in the US. Limited research has examined how stress impacts e-cigarette use among young people. We examine the longitudinal associations between perceived stress scale (PSS) score and e-cigarette use behaviors among a diverse cohort of emerging adults. We analyzed two waves of data collected in Fall 2019 (baseline) and Spring 2020 (6-month follow-up) of the Texas Adolescent Tobacco and Marketing Surveillance (TATAMS) system. Participants were classified into three mutually exclusive subsamples at baseline: (1) n = 1177 never e-cigarette users; (2) n = 806 ever but not current (past 30-day) e-cigarette users (i.e., ever users); and (3) n = 257 current (past 30-day) e-cigarette users. Three multivariate logistic regression models examined the relationship between PSS at baseline and: (1) initiation among never users; (2) progression to current use among ever users; and (3) continuation among current users, at 6-month follow-up. PSS scores were standardized using z-scores. Models controlled for race/ethnicity, sex, age, ever marijuana use, and ever use of other tobacco products. Mean age ranged from 18.6 to 19.4 among cohorts. Risk for e-cigarette progression among ever users (aOR: 1.30; 95%CI: 1.01-1.69) and e-cigarette continuation among current users (aOR: 1.33 (95%CI: 1.01-1.75) increased with each unit increase in PSS score at baseline. PSS at baseline was not associated with e-cigarette initiation among never users. PSS predicted greater risk of e-cigarette progression and continuation but not initiation among a diverse cohort of emerging adults. E-cigarette prevention and cessation strategies should consider perceived stress an important risk factor for e-cigarette use during emerging adulthood.

Substance Use Among Youth During the COVID-19 Pandemic: a Systematic Review

PURPOSE OF REVIEW

To review the literature on the trends in substance use among youth during the coronavirus SARS-CoV-2 (COVID-19) pandemic.

RECENT FINDINGS

The pandemic has given rise to concerns about the mental health and social well-being of youth, including its potential to increase or exacerbate substance use behaviors. This systematic review identified and included 49 studies of use across alcohol, cannabis, tobacco, e-cigarettes/vaping, and other drugs, and unspecified substances. The majority of studies across all categories of youth substance use reported reductions in prevalence, except in the case of other drugs and unspecified drug and substance use, which included three studies that reported an increase in use and three studies that reported decrease in use. Overall, the results of this review suggest that the prevalence of youth substance use has largely declined during the pandemic. Youth substance use in the post-pandemic years will require monitoring and continued surveillance.
