Cannabis cessation among youth: rates, patterns and academic outcomes in a large prospective cohort of Canadian high school students

Introduction Following cannabis legalization in Canada, a better understanding of the prevalence of unprompted cannabis use reduction and subsequent effects on youth academic outcomes is needed to inform harm reduction and health promotion approaches. Methods We analyzed a longitudinally linked sample (n = 91774) from the COMPASS prospective cohort study of Canadian high school students attending Grades 9–12 in Ontario and Alberta between 2013–2014 and 2016–2017. We investigated the prevalence of spontaneous cannabis use reduction and cessation between grade transitions (Grades 9–10, 10–11, 11–12) and the effect of cessation on academic achievement (current or recent math and English course marks) and rigour (usual homework completion and past-month truancy). Results Only 14.8% of cannabis users decreased their use between grades. Of these, two-thirds made only incremental downward changes, a pattern which held true for all three transitions. Cessation rates from daily and weekly use decreased every year. After cessation, students had better odds than continuing users (OR = 1.23, 95% CI: 1.03– 1.48) and worse odds than never-users (OR = 0.55, 95% CI: 0.31–0.97) for some subcategories of math performance. Students who quit cannabis universally improved class attendance (OR = 2.48, 95% CI: 1.93–3.19) and homework completion (OR = 2.32, 95% CI: 1.85–2.92) compared to continuing users. Conclusion Increased academic rigour may underlie any improvements seen in academic performance after cannabis cessation. High school students who use cannabis likely need targeted support to facilitate reduction or cessation and subsequent academic recovery. This indicates that a school-based focus on cannabis harm reduction is justified.

Ninth Grade Students

This study examined the association between participation in a school-based group-mentoring program (Project Arrive) and academic outcomes in a group of ninth-grade students who had been identified as at high risk of high-school dropout ( n = 239). Comparison participants were ninth-grade students with similar levels of risk ( n = 980). Using inverse probability of treatment weighting (IPTW) with a propensity score to reduce selection bias, and a partially clustered model to account for nonindependence of data in program students, we found that Project Arrive students earned more credits by the end of 9th grade and 10th grade; and reported increased instructional time by the end of 9th grade, than comparison students.

Youth Risk Behavior

Abstract Objective To determine the relationship between lifetime e-cigarette use and current cannabis use among youth. Our analyses accounted for county variability, in addition to student-level covariates. Methods This study examined responses from high school students on a state-level population survey, the 2018 Maryland Youth Risk Behavior Survey/Youth Tobacco Survey, a cross-sectional, complex survey sample. Of participating students, final analyses included an unweighted sample of 41,091 9th to 12th grade students who provided complete reports for measured variables. Analyses with survey weights were conducted between August 2019 and May 2020. A multivariable logistic regression was conducted to investigate the association between lifetime e-cigarette use and current (past 30-day) cannabis use, after controlling for county, lifetime cigarette use, current (past 30-day) alcohol use, emotional distress, and demographics. Results Lifetime e-cigarette use significantly increased the odds of current cannabis use among Maryland high school students (aOR = 6.04; 95% CI 5.27, 6.93). Other significant risk factors for current cannabis use included lifetime cigarette use (aOR 2.23, 95% CI 1.86, 2.68) and current alcohol use (aOR 5.21, 95% CI 4.42, 6.14). Significantly higher odds of current cannabis use were also found among older high school students, males, non-Hispanic Blacks and students identifying as other race, and those reporting emotional distress. Conclusions Lifetime e-cigarette use among Maryland high school students is strongly associated with current cannabis use when including counties as a covariate. Non-significant county differences, however, suggest smaller geographical units may be required to control for variability. Efforts should focus on reducing youth e-cigarette use to decrease cannabis use. Maryland’s recent implementation of Tobacco 21 and a ban on flavored e-cigarettes will be of interest for future evaluations.

The EAGLE project was a Euratom FP7 which helped to identify and disseminate good practices in information and communication processes related to ionizing radiation. For this purpose, the consortium reviewed national and international data, tools and methods as well as institutional work in order to identify education, information and communication needs. Generally in high school the first concepts on radioactivity and ionizing radiation (IR) are introduced mainly in the subjects of physics or physical chemistry. There are a number of concepts in relation with IR and nuclear topics, and different ways to teach them: theoretical, mathematical, historical or practical. The question also rose, to what extend the various topics related to ionizing radiation (health, environment, history) are dealt with. As already mentioned, all these questions let to the idea to compare the content dealing with radioactivity and nuclear topics in different physics school books and more specifically schoolbooks for high school students (in the age 17 to 18). The method was as follows: - For the review the different partners of EAGLE have sent the schoolbooks used for the target group, or scanned documents. - Spanish schoolbooks and English schoolbooks were purchased to extend the review to other EU countries. - IRSN works in partnership with a high school based in the French town Vichy. - Each book was analyzed in detail to list with precision the content. A matrix helped to compare them. The paper presents the comparison of the contents of these books and their analysis. Some recommendations coming from the Eagle project will be discussed.

OBJECTIVES: Students attend sedentary life style and less like vigorous physical activity. This study investigated the effects of School-based intervention on increasing physical activity for decreasing obesity among high-school obese and overweight boys, based on the components of PRECEDE PROCEED Model, to participate in median - vigorous physical activity among the first Period of high school boys in the city of Urmia, IranMETHODS: This study was an experimental intervention that conducted at 4 high schools that were divided into 2 groups of intervention (40) and the control (40) male students, schools in junior high schools in Urmia.RESULTS: Three and six months after the intervention, significant differences were found between the experimental and control groups of schools, in the amount of students’ participation in vigorous physical activity (p<0.01).CONCLUSIONS: According to the results, the school-based intervention and components of PRECEDE PROCEED Model had a positive impact on the improvement of physical activity and decrease in physical inactivity among the students.

Facilitating Factors

Objective: To contribute to the development of tailored school-based physical activity interventions, in this study, we aimed to identify the perceived facilitating factors and barriers of high school students toward their physical activity in the school environment. Methods: A total of 139 students from 4 different high schools completed an online questionnaire comprising open-ended questions on their perceived facilitating factors and barriers toward their physical activity at school. Thereafter, 100 of these students participated in one of the 16 focus groups designed to deepen students’ responses regarding their perceived facilitating factors and barriers. Qualitative content analysis was performed to classify data according to the Social-Ecological Model. Results: Through questionnaires, students mostly identified intrapersonal elements as facilitating factors and barriers to their practice of physical activity, as opposed to institutional factors during the focus groups. Girls strongly valued the characteristics of the interventions and of the involved school stakeholders. Conclusions: Our results allow us to qualify the current understanding of high school students’ perceived facilitating factors and barriers toward school-based physical activity and strengthen the relevance of surveying students prior to the development and implementation of physical activity interventions.
