The legalization of hemp cultivation in the United States has provided opportunities for farmers to grow a new crop. Despite these opportunities, significant social, economical, and technical challenges to growing hemp have been well documented. The purpose of this research was to explore Nebraska conventional farmers' perceptions toward hemp cultivation. Using the diffusion of innovations theory as a framework, one-on-one interviews were conducted with seven conventional farmers in Nebraska. Data were analyzed using deductive coding methods. Results are presented in four emergent themes describing farmer perceptions: 1) limited prior exposure; 2) perceived technical challenges; 3) advantages; and, 4) impartial feelings.

Black, school-aged youth may experience socioeconomic, psychological, and emotional difficulties that affect their mental health, leading to maladaptive ways of coping, such as cannabis use. Instead of getting treatment and support to help them manage their stressors in positive ways, Black youth often receive punitive school practices, including referrals to the juvenile justice system. Counselors who work with school-aged youth are likely to encounter many Black youth and can thus either be instrumental to their psychological development or inadvertently impede their well-being with over-pathologization and criminalization of their cannabis use. In this article, the author reflects on a particular experience he had working with a Black youth and how it influenced his cultural competency and development as a counselor. The author also discusses the socioeconomic landscape and psychological experience of Black youth and their rationale for cannabis use. The article concludes with implications for professional counselors.

Background: The conceptual framework for "School as a Protective Factor" approach was presented in a companion article in this issue of the journal. The current article describes the validation of the "School as a Protective Factor-Brief (SPF-Brief)," a 13-item survey measuring the 3 core constructs and 13 defining characteristics of this framework. Methods: The "SPF-Brief" was validated through 2 studies. The developmental study used a longitudinal design including 1349 participants who completed surveys over 5 semesters, while the validation study used a cross-sectional design with 2775 participants. Both studies included middle and high school students. Factor analysis, growth model analysis, criterion-related validation, and outcome analysis were employed. Results: Analyses provided strong evidence supporting the reliability and validity of the instrument and conceptual framework. Higher "SPF-Brief" scores were associated with higher math grades, English grades, and quality of life, as well as lower rates of anxiety, depression, conduct disorder, alcohol, e-cigarette, tobacco, and cannabis use. Effect size estimates ranged from moderate to strong. Conclusions: These findings suggest the utility of the "SPF-Brief" instrument and the "School as a Protective Factor" framework. Together, they may offer advantages to the traditional school climate approach.

Objective: To determine if treatment of co-occurring adult ADHD and Cannabis Use Disorder (CUD) with extended-release mixed amphetamine salts (MAS-ER) would be effective at improving ADHD symptoms and promoting abstinence. Method: A 12-week randomized, double-blind, two-arm pilot feasibility trial of adults with comorbid ADHD and CUD (n = 28) comparing MAS-ER (80 mg) to placebo. Main outcomes: ADHD: [greater than or equal to] 30% symptom reduction, measured by the Adult ADHD Investigator Symptom Rating Scale (AISRS). CUD: Abstinence during last 2 observed weeks of maintenance phase. Results: Overall, medication was well-tolerated. There was no significant difference in ADHD symptom reduction (MAS-ER: 83.3%; placebo: 71.4%; p = 0.65) or cannabis abstinence (MAS-ER: 15.4%; placebo: 0%; p = 0.27). MAS-ER group showed a significant decrease in weekly cannabis use days over time compared to placebo (p < 0.0001). Conclusions: MAS-ER was generally well-tolerated. The small sample size precluded a determination of MAS-ER's superiority reducing ADHD symptoms or promoting abstinence. Notably, MAS-ER significantly reduced weekly days of use over time.

Background: While a theoretical association between religiosity and substance use is anticipated, there is limited empirical evidence testing this theoretical proposition among Nordic adolescents. It was anticipated that studying these substance-use correlates from a criminological perspective by employing a large sample of students could provide novel as well as specific knowledge and insights of substance use in a Nordic setting and others. Objective: This study aimed to explore the effects of organizational and subjective religiosity on substance use (cannabis and alcohol) among a large sample of Nordic middle and high school students. Method: The data were extracted from two waves of the Young in Norway (UNGDATA Vestland County) cross-sectional surveys conducted in 2017 and 2021 (N = 41,096). Three binomial logistic regression analyses were carried out separately for the samples for each year (2017 and 2021) to examine the effects of religiosity, social bonding, and rule-breaking behavior on substance use among those adolescents that completed the survey. Results: The prevalence of cannabis use (6.3% in 2017 vs. 6.6% in 2021) and binge drinking (29.7% in 2017 vs. 29.5% in 2021) did not change significantly over time. Religiosity weakly predicted cannabis use but was consistently associated with low levels of binge drinking. The introduction of social bonding variables weakly influenced the association between religiosity and substance use. Social bonding was associated with low levels of cannabis use, but it had varying effects on binge drinking. Sociodemographic variables and rule-breaking behavior were consistent over time in predicting substance use. Conclusions: Subjective and organizational religiosity exert distinct influences on adolescent substance use, with the religiosity model exhibiting a stronger predictive capacity for binge drinking compared to cannabis use over the years.

Reservation-dwelling American Indian adolescents are at exceedingly high risk for cannabis use. Prevention initiatives to delay the onset and escalation of use are needed. The risk and promotive factors approach to substance use prevention is a well-established framework for identifying the timing and targets for prevention initiatives. This study aimed to develop predictive models for the usage of cannabis using 22 salient risk and promotive factors. Models were developed using data from a cross-sectional study and further validated using data from a separate longitudinal study with three measurement occasions (baseline, 6-month follow-up, 1-year follow-up). Application of the model to longitudinal data showed an acceptable performance contemporaneously but waning prospective predictive utility over time. Despite the model's high specificity, the sensitivity was low, indicating an effective prediction of non-users but poor performance in correctly identifying users, particularly at the 1-year follow-up. This divergence can have significant implications. For example, a model that misclassifies future adolescent cannabis use could fail to provide necessary intervention for those at risk, leading to negative health and social consequences. Moreover, supplementary analysis points to the importance of considering change in risk and promotive factors over time.

An important public concern about the impact of recreational cannabis legalization is how it may affect adolescent cannabis use. Prior research on this issue has primarily focused on the implications of "medical" cannabis legalization for adolescents and used data that cover a relatively short post-legalization period. This study extends this line of research by examining the relationship between "recreational" cannabis legalization and adolescent cannabis use in Washington State, using the National Survey of Drug Use and Health (NSDHU) data from 2005 to 2019. Based on a quasi-experimental research design, this study found some evidence suggesting a positive effect of recreational legalization on the prevalence of adolescent cannabis use and cannabis initiation. Findings suggest the need to create a cannabis regulatory environment that minimizes adolescent access to this drug.

Little is known about the implications of cannabis legalization on adolescent health behaviors. This study sought to examine the relationship between recreational cannabis legalization and adolescent sexual risk behaviors. Data on 371,487 respondents who have ever had sexual intercourse from 41 states in the 2005 to 2019 Youth Risk Behavior Survey was linked with data on state-level cannabis policies. Difference-in-differences logistic regression models were conducted. Recreational cannabis legalization was associated with a reduced likelihood of respondents having 2+ sexual partners (adjusted OR [aOR] 0.63, 95% CI [0.47, 0.84]), but had no association with condom use (aOR 0.94, 95% CI [0.80, 1.11]). Changing social norms around cannabis is a potential pathway linking cannabis legalization to a reduction in sexual risk behaviors.

Prenatal cannabis use and maternal stress have been proposed as risk factors for autism spectrum disorder (ASD). Black mothers and mothers of lower socioeconomic status (SES) may be especially likely to experience high levels of stress. This study examined the impact of prenatal cannabis use and maternal stress (i.e., prenatal distress, racial discrimination, and lower SES) on child ASD-related behaviors in a sample of 172 Black mother-child pairs. We found that prenatal stress was significantly associated with ASD-related behaviors. Prenatal cannabis use did not predict ASD-related behaviors and did not interact with maternal stress to predict ASD-related behaviors. These findings replicate previous work on prenatal stress-ASD associations and add to the limited literature on prenatal cannabis-ASD associations in Black samples.

Marijuana use among U.S. college students is the highest since the mid-1980s. Because knowledge about marijuana and confidence in the knowledge are related to changing marijuana laws and marijuana-related messages ubiquitous in college students' information environment, we examined their relationships with use. The Structural Equation Modeling method was used to analyze the relationships using survey responses from 249 college students in an adult-use marijuana legal state. Marijuana health knowledge was related to less use, and law knowledge was related to more use. Both relationships were mediated by perceived risk. Confidence in knowledge was related to more use directly as well as indirectly via lower peer disapproval and lower perceived risk. Among various marijuana message channels, peers were the most influential, contributing to lower health knowledge and higher confidence in knowledge.

The present study aimed to test if perceived pubertal timing was related to marijuana and alcohol use through deviant peer affiliation. Additionally, we examined if the deviant peer pathway was moderated by impulsiveness, gender, or both. Data were collected from 342 youth, most of whom had a family history of substance use disorder. Youth completed assessments every six months from age 13 to 16. For girls only, longitudinal analyses revealed that perceived pubertal timing was indirectly related to substance use through higher levels of deviant peer affiliation. This pathway was moderated by impulsiveness such that the association between perceived pubertal timing and deviant peer affiliation was only present for girls with average to high levels of impulsiveness. These findings elucidate a developmental pathway from perceived pubertal timing to substance use through deviant peer affiliation for high-risk girls, although low levels of impulsiveness were protective.

Substance use in adolescence is a significant public health issue, particularly in early-to-mid adolescence, which represents a window of risk in the etiology of substance abuse and dependence. Substance use during this development period often results from affiliation with deviant peers, who model, facilitate, and reinforce use. Existing school-based substance use prevention programs have historically aimed to build adolescent knowledge regarding the dangers of substance use and/or enhance peer refusal skills. Research finds that these programs have had some success in reducing substance use, but meta-analyses report that average effect sizes are small. In a small one-year cluster randomized trial (12 middle and high schools; N = 813 students; ClinicalTrials.gov: NCT04478240), cooperative learning (CL) was implemented with the support of specialized technology and evaluated for its ability to reduce deviant peer affiliation and, in turn, reduce substance use. CL is a structured approach to small-group learning that provides at-risk youth with the opportunity to build friendships with more prosocial youth, interrupting the process of deviant peer clustering. Multi-level modeling revealed intervention effects for deviant peer affiliation and alcohol use across the sample, while tobacco use was significantly reduced among non-White students; intervention effects for marijuana use were only marginally significant. Effects for dosage were found for all outcomes, suggesting that every lesson taught had a significant impact. We conclude that CL, delivered with the aid of specialized technology, represents a viable option for universal substance use prevention. Future research should attempt to combine this approach with evidence-based prevention curricula.

Objective: To compare physical activity (PA), sitting time, and substance use pre-COVID-19 and during COVID-19 pandemic among US college students. Participants: 484 students from a large Western university (20.6 ± 1.4 years, 80.0% female) were recruited. Methods: Self-reported online surveys were completed in June-August 2020. T-tests and non-parametric analyses were conducted for continuous and ordinal variables respectively. Results: Vigorous PA, moderate PA, and light PA decreased significantly by 32%, 27%, and 21% and sitting time increased significantly by 49% from pre-COVID-19 to during COVID-19 pandemic. Wine consumption was less during COVID-19 than pre-COVID-19 among female, non-first-generation, and White students. Sleep aids use was more frequent during COVID-19 than pre-COVID-19 pandemic among non-first-generation and White students. Conclusion: COVID-19 pandemic may influence college students' health behaviors including physical activity patterns, sitting time, and substance use. Effective health promotion and coping strategies should be widely available to college students during times of change and uncertainty.

Objective: To compare the prevalence and trajectories of risky health behaviors in sexual minority (SM; lesbian/gay/bisexual/questioning/asexual) versus heterosexual undergraduates across their first year of post-secondary. Participants: First-year undergraduates (N = 704, M[subscript age] = 17.97 years, 24% SM) from a midsized Canadian university. Methods: Students completed monthly (September-April) online questionnaires assessing substance use (binge drinking, tobacco, cannabis, illicit drug use) and disordered eating (binge eating, fasting, purging). Results: At the outset of the academic year, SM students endorsed more frequent cannabis use, illicit drug use, fasting, and binge eating, but less frequent tobacco use, versus heterosexual students. Over the year, SM students' binge drinking frequency declined less than that of heterosexual students, but their illicit drug use decreased while that of their heterosexual peers increased, and all students reported declining disordered eating frequency. Conclusions: Campus wellness initiatives for SM students should offer prevention and harm-reduction strategies prior to or shortly after their arrival on campus.

Objective: Kratom use represents a growing risk for public health. The present study examined demographic and behavioral factors linked with kratom use. Participants: Participants were college students in the United States who participated in the 2019-2020 Healthy Minds Study. Methods: Participants completed survey-based assessment of kratom use and related demographic, behavioral, and mental health variables. Results: Kratom use was linked with being White, male or transgender/gender nonconforming, identifying as a sexual minority, use of alcohol or marijuana, and depressive symptoms. Kratom use was not uniquely linked to exercise or anxiety. Conclusions: The results of the present study can be used to inform initial targeting of efforts to reduce kratom use among college students.

Alcohol and other drug (AOD) use problems among college students continue to represent a public health epidemic. In 2019, historically high rates of binge-drinking and marijuana use were reported among college-age adults, and the detrimental effects of excessive AOD use in college, such as poorer academic performance, sexual assault, injury or overdoses, and a range of other negative consequences, have been well-documented. Thus, there is a continued need for effective implementation of evidence-based, cost-effective interventions aimed at reducing risks associated with collegiate AOD use. Guided Self Change (GSC) is a brief intervention involving motivational enhancement and cognitive-behavioral strategies and has demonstrated effectiveness in reducing AOD use problems. Its brevity, client-driven style, and concrete here-and-now focus are appealing to individuals struggling with mild to moderate AOD use problems. In order to successfully intervene with collegians with AOD use problems attending minority-serving institutions, GSC requires developmental and cultural tailoring. The current report describes the developmental and cultural tailoring of GSC for emerging adult Latinx collegians, as well as our consumer-driven addition of mindfulness content. Key components of our GSC program are documented through qualitative feedback, quantitative results, and case vignettes.

Objective: College students use electronic nicotine delivery systems (ENDS) more often than any other US demographic group. In a novel application of the acquired preparedness model, we examined how proximal (e.g., cognitions) and distal (e.g., dispositional) influences accounted for ENDS use and dependence. Participants: Undergraduates (N = 1075; 72% female, 74% White) from seven US campuses completed an online survey between October 2019-March 2020. Methods: We modeled ENDS use and dependence, respectively, as zero-inflated Poisson distributions with impulsivity as an independent variable and perceived risks and benefits of e-cigarettes as mediators. Results: Students higher in impulsivity perceived more benefits and, in turn, reported greater ENDS use and dependence. Curiosity and friends' use motivated ENDS initiation; stress management and nicotine motivated continued use. Conclusions: ENDS interventions should be tailored to students higher in impulsivity, as they hold more favorable perceptions of ENDS, and should enhance skills to manage stress and nicotine cravings.

This study explored substance use trajectories and associations with mental health among an ethnically/racially diverse college student sample before and during the COVID-19 pandemic. We combined repeated cross-sections and panel data from a total of 3,247 college students assessed with an online survey in 2018, 2019, and in three waves in 2020. We estimated trends in substance use and their relation to mental health over the survey waves using generalized estimating equations (GEE). Our results revealed notable associations between 30-day substance use patterns, time of assessment, and psychological well-being. These findings suggest a complex interplay between access to substances, context of substance use, and mental health. We discuss several initiatives that have been launched in response to the results of this ongoing study. Such initiatives may serve as examples for expanding similar efforts to other commuter colleges to prevent further increases in mental health problems and risky substance use.

Objective: This study examined joint trends over time in associations between substance use (heavy drinking, cannabis, and cigarette smoking) and mental health concerns (depression, anxiety, and suicidal ideation) among US post-secondary students. Participants: Data came from 323,896 students participating in the Healthy Minds Study from 2009 to 2019, a national cross-sectional survey of US post-secondary students. Weighted two-level logistic regression models with a time by substance interaction term were used to predict mental health status. Results: Use of each substance was associated with a greater odds of students endorsing depression, anxiety, and suicidal ideation. Over time, the association with mental health concerns strengthened substantially for cannabis, modestly for heavy drinking, and remained stable for smoking. Conclusion: Given co-occurrence is common and increasing among post-secondary students, college and university health systems should prioritize early identification, psychoeducation, harm-reduction, and brief interventions to support students at risk.

Objective: The purpose of this study was to examine patterns of concurrent cannabis and other substance use and their differential associations with cannabis-related problems and academic outcomes in college students. Participants: Participants were undergraduate students (N = 263; M age = 19.1 years; 61.2% female) who were eligible if they used cannabis at least 3 days in the past month (M = 10.1 days). Method: Substance use, academic-related outcomes, and measures of Cannabis Use Disorder (CUD) severity and problems were obtained in an online survey. Results: The five groups evaluated were cannabis-only users (5.3%), cannabis and alcohol (47.1%), cannabis, alcohol and cigarettes (16.7%), cannabis, alcohol and other substances (14.8%), or all-substances (16%). Cannabis-only and all-substance users reported using cannabis most frequently (ps [less than or equal to] 0.034), but only the latter reported greater CUD severity, problems, and poorer academic outcomes. Discussion: College student polysubstance users may be at increased risk for poorer outcomes compared to cannabis-only users and other groups.

Objective: Examine the proportion of students with rapid firearm access and associations with recent alcohol and marijuana use. Participants: Cross-sectional data from college freshmen (n = 183) in 2020 who participated in the "Mason: Health Starts Here" study. Methods: Using logistic regression, associations were examined between past 30-day substance use and access to firearms within 15-min. Results: More than 10% of students could rapidly access a firearm, 53% of whom were current binge drinkers, compared to 13% of those who could not rapidly access firearms. Non-Hispanic White students (AOR = 4.1, 95%CI = 1.3,12.7) and past 30-day binge drinkers (AOR = 6.4, 95%CI = 2.1,19.7) had greater odds of having rapid firearm access. Age, sex, and past 30-day marijuana use were not associated with rapid access. Conclusions: A notable proportion of students had rapid firearm access, which was strongly associated with recent binge drinking. Campus prevention programs should consider how their alcohol and firearm policies could be enhanced to prevent violence/self-harm.

Background: Tobacco use continues to be a leading cause of morbidity and mortality in the United States. Rates of tobacco use among college students remain steady with one in ten using some form of tobacco. Specific social and demographic correlates to use are needed to effectively address continued use. Purpose: The purpose of the present study was to examine specific factors associated with daily tobacco use among college students. Methods: The National College Health Assessment was disseminated in classrooms to students at one urban, Midwestern university. Results: Results indicated 8.4% of college students used some form of tobacco daily. The final model found gender and marijuana use predicted daily tobacco use. Discussion: Based on the prevalence rates found in the present study, it is evident that public health professionals are growing concerned regarding the significant adverse health effects of tobacco use. Translation to Health Education Practice: Health education programs targeting college students engaged in risky behaviors could help reduce tobacco use on college campuses. Health education interventions that address smoking cessation, alcohol, and drug abuse, and mental health support could effectively reduce daily tobacco use on college campuses.

Objective: Among two-year college students, alcohol and marijuana use, related consequences, and risk factors for use are not well understood. We examined differences between two- and four-year students in alcohol and marijuana use, consequences, and perceived descriptive norms, and explored whether two-year status moderated associations between norms and use. Participants: Data were drawn from a cross-sectional subsample of two- and four-year students aged 18-23 (n = 517) participating in a longitudinal study on alcohol use. Results: Four-year students reported greater alcohol use and consequences than two-year students; two-year students reported greater marijuana use than four-year students. Perceived alcohol and marijuana norms were positively related with use; two-year status did not moderate these associations. Conclusions: Perceived alcohol and marijuana norms function similarly for two- and four-year students in terms of associations to actual use. Adapting normative interventions for two-year students may be an effective strategy for reducing high-risk use among this underserved population.

Objective: Around 40% of US university students use cannabis, 25% of whom present with cannabis use disorder, which endangers health. We investigated the concurrent contribution of reflective processes, which generate action via conscious deliberation, and non-reflective processes, which prompt behavior automatically, to undergraduates' cannabis consumption. Participants: Eighteen UK undergraduates who regularly consume cannabis (11 female, 7 male; mean age 20 y). Methods: Semi-structured interviews explored cannabis motives, routines, cues, and decision points. Thematic analysis identified themes, in each of which reflective and non-reflective dimensions were coded. Results: Four themes were identified: cannabis use for relaxation, social bonding, and symbolic-affective significance, and contexts and triggers. Some influences guided cannabis use reflectively in some settings, and non-reflectively in others. Even when cannabis use was consciously driven, non-reflective processes were deployed to execute subservient acts, such as rolling joints. Conclusions: Findings highlight specific processes and pathways that might be targeted to reduce cannabis-related harm.

Objective: Electronic cigarette use represents an important college health concern. This investigation assessed demographic and behavioral correlates associated with actual and perceived e-cigarette use among a national sample of American college students. Methods: Respondents (n = 19,861) comprised college students from over 40 distinct American higher education institutions. Multivariable logistic regression assessed whether (1) alcohol, tobacco or marijuana use were associated with e-cigarette use; (2) perceived peer use of alcohol, tobacco or marijuana were associated with perceived e-cigarette use. Results: Approximately 5% of survey respondents self-reported using e-cigarettes within the past month. More than 7 out of every 10 respondents, however, thought the 'typical student' was an e-cigarette user. As perceptions of typical student substance use increased, respondents were far more likely to contend the typical student used e-cigarettes. Discussion: In addition to adopting smoke-free campus policies, university officials should disseminate accurate information regarding e-cigarette behaviors of students.

Objective: Electronic Nicotine Delivery System (ENDS) proprietors strategically placed near college campuses and pervasive marketing on social media platforms, such as Facebook, are critical to the tobacco industry's effort to acquire new young adult users. Understanding the themes used on Facebook to promote ENDS products to college students is necessary to develop public health messaging to combat the vaping epidemic. Methods: We identified 15 ENDS proprietors located near four Big 10 universities and qualitatively analyzed a random sample of their Facebook posts (n = 405) to identify emerging themes using a grounded theory approach. Results: ENDS proprietors in college towns use Facebook to deploy "promotional" messaging (n = 319), to market ENDS products as a means of celebration (n = 40), to establish a sense of "community" (n = 155) among ENDS users, to make "marijuana references" (n = 36), and to "advocate" (n = 27) for ENDS products. Conclusions: These themes may increase social acceptability and use of ENDS products among college students.

Given the prevalence of alcohol and cannabis co-use among college students, prevention for co-use is crucial. We examined hypothetical receptiveness to substance-specific interventions among students who reported co-use. Students who use alcohol and cannabis were more receptive to alcohol interventions than cannabis interventions. Campus prevention experts should consider offering evidence-based, alcohol-focused interventions as a potential pathway for decreasing substance use among college students who engage in co-use.

School bullying and cyberbullying are serious public health problems that negatively affect the lives of school-aged children. We examined the correlation between risk behaviors and lack of resiliency factors with bullying and cyberbullying across seven Mediterranean countries. The sample consisted of 33,399 adolescents (51.1% girls) aged 11, 13, and 15 years who participated in the Health Behavior in School-aged Children (HBSC) survey in 2018 in Greece, Israel, Italy, Macedonia, Malta, Portugal, and Spain. Bivariate logistic regressions were conducted to test the relationship between risk behaviors, resilience, and bullying. All risk behaviors and lack of resiliency factors examined were related to involvement in bullying as a victim, perpetrator, or bully-victim, both in school and cyberbullying. Moreover, the odds of involvement in school bullying and cyberbullying increased as the number of risk behaviors and the lack of resiliency factors grew. Our results may contribute to the development and implementation of anti-bullying programs.

Background: High cannabis use rates among American Indian (AI) adolescents necessitate the identification of factors that protect against early cannabis initiation. Methods: Data collected from 279 AI middle school students attending reservation-based schools in 2018 and 2019 were analyzed. Three waves of data, with approximately 6 months between each, were used. A repeated measures latent class analysis examined a school-related protective factor index over three waves. The predictive power of lifetime cannabis use on school protection class membership was estimated, along with differences in past month cannabis use at follow-up 2 across school protection classes while holding baseline use constant. Results: Four school protection classes were identified: high, moderate, low, and declining protection. Abstinence at baseline was associated with an increased odds of membership in the high protection class compared to the moderate and low protection classes. Students with consistent and high school protection throughout middle school were significantly less likely to report past month cannabis use at follow-up 2 compared to other classes. Implications for School Health Policy, Practice, and Equity: Maintaining a high level of school protection throughout middle school substantially lowers the odds of cannabis use among AI adolescents. Conclusions: Interventions to promote school-related protective factors in this population are essential and should be designed and tested.

Racial disparities are evident in both educational outcomes and incarceration rates when comparing African American and white youth. It is essential to understand the school-to-prison pipeline and the ways in which school discipline practices and other factors disproportionately affect African American students, limit educational attainment, and increase risk for future incarceration in order to improve students' educational and life outcomes. This study explores how marijuana, anxiety and locus of control interact with school disciplinary practices in pushing students out of schools and into the criminal justice system. Analyses utilizing data from the Woodlawn Study, a longitudinal study of African Americans followed from first grade through adolescence, young adulthood, and midlife (n = 1,242), reveal that suspension or expulsion, frequent marijuana use, and locus of control (males only) all predict criminal justice system involvement above and beyond not graduating from high school, but do not interact significantly. This study offers avenues for intervention to reduce disparities.

A primary community prevention approach in Iceland was associated with strong reductions of substance use in adolescents. Two years into the implementation of this prevention model in Chile, the aim of this study was to assess changes in the prevalence of adolescent alcohol and cannabis use and to discuss the impact of the COVID-19 pandemic on the substance use outcomes. In 2018, six municipalities in Greater Santiago, Chile, implemented the Icelandic prevention model, including structured assessments of prevalence and risk factors of substance use in tenth grade high school students every 2 years. The survey allows municipalities and schools to work on prevention with prevalence data from their own community. The survey was modified from an on-site paper format in 2018 to an on-line digital format in a shortened version in 2020. Comparisons between the cross-sectional surveys in the years 2018 and 2020 were performed with multilevel logistic regressions. Totally, 7538 participants were surveyed in 2018 and 5528 in 2020, nested in 125 schools from the six municipalities. Lifetime alcohol use decreased from 79.8% in 2018 to 70.0% in 2020 (X[superscript 2] = 139.3, p < 0.01), past-month alcohol use decreased from 45.5 to 33.4% (X[superscript 2] = 171.2, p < 0.01), and lifetime cannabis use decrease from 27.9 to 18.8% (X[superscript 2] = 127.4, p < 0.01). Several risk factors improved between 2018 and 2020: staying out of home after 10 p.m. (X[superscript 2] = 105.6, p < 0.01), alcohol use in friends (X[superscript 2] = 31.8, p < 0.01), drunkenness in friends (X[superscript 2] = 251.4, p < 0.01), and cannabis use in friends (X[superscript 2] = 217.7, p < 0.01). However, other factors deteriorated in 2020: perceived parenting (X[superscript 2] = 63.8, p < 0.01), depression and anxiety symptoms (X[superscript 2] = 23.5, p < 0.01), and low parental rejection of alcohol use (X[superscript 2] = 24.9, p < 0.01). The interaction between alcohol use in friends and year was significant for lifetime alcohol use ([beta] = 0.29, p < 0.01) and past-month alcohol use ([beta]= 0.24, p < 0.01), and the interaction between depression and anxiety symptoms and year was significant for lifetime alcohol use ([beta] = 0.34, p < 0.01), past-month alcohol use ([beta] = 0.33, p < 0.01), and lifetime cannabis use ([beta] = 0.26, p = 0.016). The decrease of substance use prevalence in adolescents was attributable at least in part to a reduction of alcohol use in friends. This could be related to social distancing policies, curfews, and homeschooling during the pandemic in Chile that implied less physical interactions between adolescents. The increase of depression and anxiety symptoms may also be related to the COVID-19 pandemic. The factors rather attributable to the prevention intervention did not show substantial changes (i.e., sports activities, parenting, and extracurricular activities).

Individuals who are deaf and use American Sign Language (ASL) as their primary mode of communication experience unique negative life experiences, such as lack of communication, limited access to services, marginalization, and discrimination, that can adversely impact resilience and psychological well-being. In addition, deaf individuals experience higher rates of intimate partner violence, polyvictimization, sexual, physical, and emotional abuse, and unemployment. These negative life experiences can sometimes be accompanied by maladaptive behaviors, such as substance use. Resilience and a positive sense of well-being can help to mitigate adverse life events. This survey research utilizes a sample of 206 deaf participants, whose primary language is ASL, and hearing participants to examine the relationships between negative life experiences, substance use, resilience, and well-being. Findings indicate: (1) deaf participants reported experiencing several negative life events significantly more often than their hearing counterparts, specifically being sent to jail or prison, having a serious physical illness, and sexual abuse by a partner than hearing participants; (2) deaf participants reported more experiences of having an abortion or miscarriage and parental separation or divorce as children than their hearing counterparts; (3) deaf individuals reported higher marijuana use than their hearing counterparts, but less use of stimulants, inhalants, and prescription drug abuse; (4) experiences of mental illness was significantly associated with resilience and well-being; and (5) deaf and hearing participants had similar scores in resilience and well-being. The author identifies strengths and limitations of the study and discusses implications for future research.

We present results of a randomized, controlled, efficacy trial of a handbook intervention for parents of first-year college students. The aim of the interactive intervention was to decrease risk behaviors by increasing family protective factors. The handbook, based in self-determination theory and the social development model, provided evidence-based and developmentally targeted suggestions for parents to engage with their students in activities designed to support successful adjustment to college. We recruited 919 parent-student dyads from incoming students enrolled at a university in the U.S. Pacific Northwest and randomly assigned them to control and intervention conditions. We sent handbooks to intervention parents in June before students' August matriculation. Research assistants trained in motivational interviewing contacted parents to encourage use of the handbook. Control parents and students received treatment as usual. Participants completed baseline surveys during their final semester in high school (time 1) and their first semester at college (time 2). Self-reported frequency of alcohol, cannabis, and simultaneous use increased across both handbook and control students. In intent-to-treat analyses, odds of increased use were consistently lower and of similar magnitude for students in the intervention condition than in the control condition, and odds of first-time use were also lower in the intervention condition. Contact from research assistants predicted parents' engagement, and parent and student report of active engagement with handbook predicted lower substance use among intervention than control students across the transition to college. We developed a low-cost, theory-based handbook to help parents support their young adult children as they transition to independent college life. Students whose parents used the handbook were less likely to initiate or increase substance use than students in the control condition during their first semester in college.

Volunteering can serve as a protective factor against substance abuse. Yet, it is unclear whether volunteering in specific community organizations, such as emergency services, promotes or protects against substance use. We aimed to (1) describe community volunteering characteristics among adolescents; (2) investigate differences in the prevalence of substance use according to community volunteering type; and (3) determine whether volunteering type was a predictor of substance use. We analyzed data from the 2018-2019 Health Behavior in School-aged Children survey among Israeli adolescents aged 11-17 years (N = 3972). Most participants (N = 2452; 61.7%) did not volunteer at all, 27.1% (N = 1077) volunteered in youth movements/councils, and 11.2% (N = 443) volunteered in community emergency services. In comparison to the emergency services group, there was a higher volunteering frequency among the youth movements/councils group. Of the three groups (nonvolunteering, volunteering in youth movements/councils, and volunteering in community emergency services), those in the community emergency services group reported a significantly higher prevalence of weekly alcohol use, lifetime cannabis use, and new psychoactive drug use, while no significant between-group differences were observed in smoking tobacco prevalence. Volunteering in the community emergency services has been linked to substance use, requiring the development of intervention programs by the school staff, before their active volunteering (e.g., guidance on emotional stress and substance abuse). Also, teachers can act as a protective factor for students, and identify emotional distress and anxiety in their students to prevent substance abuse. Furthermore, emergency services workers and instructors should also be aware of the higher risk of substance use among volunteering youth and should be given tools to better collaborate with parents and teachers in dealing with it.

Despite growing evidence to the contrary, researchers continue to posit causal links between cannabis, crime, psychosis, and violence. These spurious connections are rooted in history and fueled decades of structural limitations that shaped how researchers studied cannabis. Until recently, research in this area was explicitly funded to link cannabis use and harm and ignore any potential benefits. Post-prohibition cannabis research has failed to replicate the dire findings of the past. This article outlines how the history of controlling cannabis research has led to various harms, injustices, and ethical complications. We compare commonly cited research from both the prohibition and post-prohibition eras and argue that many popular claims about the dangers of cannabis are the result of ethical lapses by researchers, journals, and funders. We propose researchers in this area adopt a duty of care in cannabis research going forward. This would oblige individual researchers to establish robust research designs, employ careful analytic strategies, and acknowledge limitations in more detail. This duty involves the institutional recognition by funders, journals, and others that cannabis research has been deliberately misconstrued to criminalize, stigmatize, and pathologize.

In this laboratory teaching experiment, commercial cannabis oils were analyzed by undergraduate organic chemistry students using gas chromatography-mass spectrometry (GC-MS) to investigate three isomeric cannabinoids commonly found in cannabis products: cannabidiol (CBD), [delta][superscript 9]-tetrahydrocannabinol ([delta][superscript 9]-THC), and [delta][superscript 8]-tetrahydrocannabinol ([delta][superscript 8]-THC). The goal was to introduce GC-MS analysis through the relevant topic of product quality inspection, frequently used in various industries such as pharmaceuticals, cosmetics, etc. and which largely involves analyzing the chemical components of a sample. First, to better understand the cannabinoid analytes, students were taught the differences between these structural isomers, including bond locations, stereochemistry, and functional groups--factors which pertain to their pharmacology and drug classification. Finally, students were guided through the basics of GC-MS instrumentation and the process of analyzing GC-MS spectra through the characterization of CBD, [delta][superscript 8]-THC, and [delta][superscript 9]-THC present in oil samples.

The cross-sectional study assesses lifetime use of psychoactive substances in medical students. During 2018, medical students from "Universidad de Buenos Aires" (UBA) in Argentina were offered the survey. Males significantly used at least one of the substances studied once in their lives compared to women (AOR: 1.75; IC 95%= 1.11-2.77). Similarly, males used more marijuana (AOR: 1.69; 95% CI = 1.08-2.63). The lifetime prevalence increased with career level for any substance, marijuana and stimulants. Being employed was associated with lifetime consumption of marijuana (AOR: 1.6; 95% CI = 1.03-2.48). Living with peers was associated with lifetime prevalence for stimulants (AOR: 3.5; 95% CI = 1.54-7.97). This study shows a lifetime prevalence for the total substances studied was higher compared to studies in the region. Marijuana was the substance with the highest consumption, with more than half surveyed having tried it.

This article discusses how the key players' multilayered collaboration may be enacted by the Change Laboratory methodology in the footsteps of Virkkunen and Newnham (2013) to address a complex issue for the benefit of adolescents. It can be defined as a group processing approach used by a group to solve a problem of its own defining. Over six months, members of a school community played an important role in participating in the modelling of classroom lessons with adolescents facing the new guidelines of the Canadian Cannabis Act in 2018. Drawing on the theory of expansive learning and the cultural-historical activity theory (CHAT), we used the Change Laboratory approach to dialogue on the problems and solutions to be implemented. The results examine specifically how some of the school community members contributed to the co-modelling of these lessons, taking into account the adolescents' needs in two schools. The collaboration between the members evolved over time. The vertical power hierarchy usually present in schools was modified as parents, grandparents, a medical doctor, a special education teacher, two teachers, and five students agreed to sit together to address the health issue. The qualitative analysis brings to light how the participants shared their needs and engaged in taking transformative actions to intervene directly in two high school classrooms.
