‘Parents are the best prevention’? Troubling assumptions in cannabis policy and prevention discourses in the context of legalization in Canada

Reconceptualizing cannabis use risks in the context of health and social inequities: Insights from a qualitative study with young people in Canada

BACKGROUND

Cannabis became legal in Canada in 2018. Since then, calls for research to evaluate the impact of legalization on youth have been at the forefront of public and academic discussions. Research addressing these calls has largely focused on issues of risk and harm, with limited attention to the role of social context in shaping youth cannabis use. This paper presents the findings of a study that centered youth perspectives on cannabis use in the context of health and social inequities.

METHODS

Between 2021 and 2022, we undertook an exploratory and critical qualitative interview study with 56 youth from across Canada who use cannabis and who reported experiences with health or social struggles, broadly self-defined. Our analysis followed a reflexive thematic approach and leveraged theoretical perspectives from critical drug studies to interrogate youths' variegated cannabis use risks and risk environments, whilst facilitating inquiry into their interface with overlapping forms of hardship and inequity.

FINDINGS

We developed three interconnected themes: (i) cannabis use risks as contextually situated; (ii) cannabis use as a practice of care; and (iii) cannabis use as a survival tool in connection with trauma and violence. Findings within and across these themes centre on the nexus of intentionality and agency in youth narratives of using cannabis and situates their cannabis use in connection with, and in response to, intersecting health and social inequities.

CONCLUSION

This study underscores opportunities for a reconsideration or reconceptualization of risks in the context of youth cannabis use, so that approaches to supporting youth who use cannabis are more resonant and credible with those who experience health and social inequities. Findings offer direction for youth cannabis policy and programming, including to decenter individual pathology, support harm reduction goals, and further consider relationships between cannabis use and context, marginalization, and oppression.

Cannabis reduction among adolescents as spillover from successful tobacco control

BACKGROUND

National programs that reduce adolescent cannabis use warrant renewed attention in light of current discussions to reform cannabis legislation, including the possibility of legalization for recreational use. This study measures the size of a decrease in a country's prevalence of adolescent cannabis use that accompanies a decrease in its prevalence of adolescents who had ever smoked a cigarette.

METHODS

Data are from the European School Survey Project on Alcohol and Other Drugs (ESPAD), which is a collaborative effort of more than 40 European countries to surveil adolescent substance use. This study uses data from the seven survey administrations in 1995, 1999, 2003, 2007, 2011, 2015, and 2019. The main analysis is a fixed-effect regression analysis of country-level, four-year changes in adolescent lifetime cannabis use prevalence on country-level, four-year changes in adolescent lifetime cigarette use prevalence.

RESULTS

Decreases in the national prevalence of adolescents who had ever smoked a cigarette were accompanied by decreases half as large in national prevalence of adolescent lifetime cannabis use.

CONCLUSION

For European countries considering the legalization of adult recreational cannabis use, tobacco control can offer a tool to help counter potential increases in cannabis use among adolescents.

Tailoring parenting styles and family-based interventions cross-culturally as an effective prevention strategy for youth substance use: a scoping review

Background

The challenge of substance use among youth continues to be a highly concerning public health issue across the globe. The notion that parenting lifestyles and family-based intervention can help in the prevention of adolescent substance use have received robust attention from policy makers, researchers' clinicians and general public, nonetheless, there is scarcity of high quality evidence to support these concepts.

Objective

To review available literature which assessed the effects of parenting styles and family-based interventions on the prevention of adolescent substance use.

Methods

A scoping review of literature to identify studies published in English between 2012 and 2022 was conducted searching Scopus, MEDLINE, PsychInfo, and CINAHL databases focused on effects of parenting styles and family-based interventions in the prevention of adolescent substance use.Keywords of family-based intervention strategies and possible outcomes of parenting styles on youth substance use were coded from the results, discussion, or conclusion. Strategies were inductively categorized into themes according to the focus of the strategy.

Results

A total of 47 studies, published between 2012 and 2022 in English language included. Narrative synthesis illustrated that parental involvement, restriction of mature-rated content, parental monitoring, authoritative parenting styles, and parental support and knowledge can help in the prevention of adolescent substance use. On the contrary, poor parent-child bonding, overprotection, permissive parenting, parental frustrations, authoritarian and harsh parenting styles promoted adolescent substance use disorders. Proximal risk factors like peer influence, previous use of other substances, and risky behaviours had more effect than just parenting styles. Culturally tailored family-based intervention strategies such as "Preventive Parenting", "Parent Training", and "Parent Involvement", with focus on "Technology Assisted Intervention", particularly "SMART "(Substance Misuse among Adolescents in Residential Treatment) are found as effective family-based intervention strategies to mitigate substance use in youth.

Conclusion

Culturally tailored family-based behavioural strategies psychosocial intervention strategies can be considered of the most effective strategies to prevent substance use disorders in youth.

Cannabis use among youth in Canada: a scoping review protocol

INTRODUCTION

Canadian youth (aged 15-24) have the highest rates of cannabis use globally. There are increasing concerns about the adverse effects of cannabis use on youth physical and mental health. However, there are gaps in our understanding of risks and harms to youth. This scoping review will synthesise the literature related to youth cannabis use in Canada. We will examine the relationship between youth cannabis use and physical and mental health, and the relationship with use of other substances. We will also examine prevention strategies for youth cannabis use in Canada and how the literature addresses social determinants of health.

METHODS AND ANALYSIS

Using a scoping review framework developed by Arksey and O'Malley, we will conduct our search in five academic databases: MEDLINE, Embase, APA PsycInfo, CINAHL and Web of Science's Core Collection. We will include articles published between 2000 and 2021, and articles meeting the inclusion criteria will be charted to extract relevant themes and analysed using a qualitative thematic analysis approach.

ETHICS AND DISSEMINATION

This review will provide relevant information about youth cannabis use and generate recommendations and gaps in the literature. Updated research will inform policies, public education strategies and evidence-based programming. Results will be disseminated through an infographic, peer-reviewed publication and presentation at a mental health and addiction conference. Ethics approval is not required for this scoping review.

Roles and responsibilities in substance use prevention in the school setting: views among Finnish school personnel representatives

OBJECTIVE

This study explores the views of Finnish school personnel representatives regarding substance use prevention responsibilities.

DESIGN

Twenty-two focus groups were conducted within the scope of a regional intervention study in 2019. Qualitative content analysis was performed.

SETTING

Focus group interviews were conducted in the school setting.

SUBJECTS

Focus group participants included representatives for educational personnel and student welfare personnel working in basic education, general upper secondary education or vocational education settings.

MAIN OUTCOME MEASURES

Views and experiences concerning roles and responsibilities in primary prevention of substance use.

RESULTS

Findings highlight the need for intersectoral efforts and intra-school collaboration in primary prevention efforts, but also in mental health promotion - on which the informants placed great emphasis. The health promotion leadership in schools, structural guidelines and the school curriculum could both challenge and support school personnel in their roles. An increased need to focus on the early years of life and related responsibilities of the homes was emphasized, along with the need to place more emphasis on health education in the first years of basic education, and responsibilities related to early risk identification.

CONCLUSION

The findings highlight a need to develop structures and role clarity among school personnel, which can advance further development of intra-school and inter-sectoral collaboration in primary substance use prevention and mental health promotion. In the Finnish context, the successful implementation of relevant legislation, which some school representatives view as unclear or contravening, could be further supported.Key pointsViews regarding responsibilities in primary substance use prevention in the school setting have been less researched in the Nordic countries:The importance of inter-sectoral and intra-school collaboration is emphasized among school personnel representatives, including the role of the homesPrimary prevention and mental health promotion responsibilities are viewed as less clear than secondary and tertiary prevention responsibilitiesStructural guidelines concerning e.g. confidentiality aspects and curriculum features can both support and challenge school representatives in their roles.

Cannabis Policy Changes and Adolescent Cannabis Use: Evidence from Europe

Cannabis accounts for the largest share of the illicit drug market, with a high prevalence of use even among adolescents. To tackle this longstanding problem, many kinds of reforms to national cannabis control policies have been implemented in Europe, but their effectiveness is still unclear. This paper analyses the association between selected categories of cannabis policy reforms and changes in perceived cannabis availability and patterns of use among adolescents. Data from 20 European countries across 15 years were drawn from a novel database of the European school Survey Project on Alcohol and other Drugs (ESPAD). Our analysis is based on a Difference-in-Differences design, which application is allowed by the fact that only thirteen out of the twenty countries included implemented policy changes. The results suggest that selected categories of reforms influence the availability and prevalence of cannabis use. In particular, some forms of restrictive intervention reduce the general prevalence of use and more liberal reforms seem linked to an increase in the share of students initiating use of cannabis. We find no evidence of an effect of policy changes on the share of frequent users, which are presumably those more likely to develop use-related health consequences.

The Lower-Risk Cannabis Use Guidelines' (LRCUG) recommendations: How are Canadian cannabis users complying?

Canada, alongside other jurisdictions, implemented non-medical cannabis legalization in 2018, partly towards improving public health. Evidence-based 'Lower-Risk Cannabis Use Guidelines' (LRCUG), including recommendations for cannabis users on how to decrease risk-behaviors for harms, have been developed and widely disseminated in Canada since 2017. However, knowledge on users' compliance with the LRCUG is limited. We identified four major Canadian (three national, one provincial) population surveys presenting key data on cannabis-related behaviors: the National Cannabis Survey, Canadian Cannabis Survey, Canadian Tobacco, Alcohol & Drugs Survey, and CAMH Monitor. We scanned each survey for indicator data mapping onto either of the LRCUG's recommendations for the years 2017 to 2019. Relevant indicator data, albeit with varying operationalizations, were found for six of the ten LRCUG's recommendation clusters in at least some of the surveys, and were extracted and summarized. For results, substantial -- but declining -- majorities of users consumed cannabis by smoking, yet with shifts towards other use modes. Between one- to two-in-five users engaged in the risk-behaviors of using high-potency cannabis products, frequent cannabis use and cannabis-impaired driving, respectively. A small proportion of pregnant or breastfeeding women continued cannabis use during the study period. The data identified found suggested a heterogeneous picture regarding cannabis users' compliance with the LRCUG's recommendations. Non-compliance is highest for recommendations regarding modes-of-use, and applies to minorities of users for other risks factors. These sub-groups are at elevated risk for acute (e.g., accidents) or long-term (e.g., dependence) cannabis-related harms contributing to the public health burden. Appropriate targeted interventions in these areas require improvement.

Prevalence and correlates of youth poly-substance use in the COMPASS study

BACKGROUND AND AIMS

Youth poly-substance use, associated with long-term negative health and social outcomes, is of increasing concern following the rise of e-cigarette vaping and cannabis legalization in Canada. This work aimed to investigate current evidence on correlates of this behaviour to inform effective prevention and harm reduction programming.

DESIGN

Cross-sectional sample taking part in a cohort study.

SETTING

Canadian high schools (AB, BC, ON, QC) PARTICIPANTS: 74,501 Canadian high school students who completed the COMPASS student questionnaire in 2018/2019.

MEASUREMENTS

Self-report data on use of five substances (alcohol, cigarettes, e-cigarettes, cannabis, and opioids) alongside demographic factors, social and school support, and mental health-related measures.

RESULTS

Of the 39% of youth who reported current substance use, 53% reported using two or more. E-cigarette vaping was most prevalent (28%) and most often combined with other substances. Feeling supported by friends and having no problem with seeking help at school were associated with higher levels of poly-substance use. Family support, school connectedness, and school support to resist drugs decreased the risk of substance co-use.

CONCLUSIONS

The evidence presented here suggests that interventions for youth poly-substance use should rely on joint efforts between parents, schools, and communities to focus on structural factors rather than problematizing the individual.

The role of school characteristics in pre-legalization cannabis use change among Canadian youth: implications for policy and harm reduction

Reducing youth cannabis use in Canada is a public health priority with schools of interest as a potential modifier of behavior and as a venue for prevention programming. This work aimed to provide a basis for future policy and programming by evaluating pre-legalization cannabis use change patterns in schools and the impact of school characteristics on these patterns. Average rates of cannabis use behavior change (initiation, escalation, reduction, cessation) were collected from 88 high schools located in Ontario and Alberta, Canada participating in the COMPASS prospective cohort study. There was little variability in cannabis use behaviors between schools with intra-class correlation coefficients lowest for cessation (0.02) and escalation (0.02) followed by initiation (0.03) and reduction (0.05). Modest differences were found based on school province, urbanicity and student-peer use. Cannabis ease of access rates had no significant effect. Fewer than half the schools reported offering school drug use prevention programs; these were not significantly associated with student cannabis use behaviors. In conclusion, current school-based cannabis prevention efforts do not appear sufficiently effective. Comprehensive implementation of universal prevention programs may reduce cannabis harms. Some factors (urbanicity, peer use rates) may indicate which schools to prioritize.

Gender Norms, Roles and Relations and Cannabis-Use Patterns: A Scoping Review

Currently, boys and men use cannabis at higher rates than girls and women, but the gender gap is narrowing. With the legalization of recreational cannabis use in Canada and in multiple US states, these trends call for urgent attention to the need to consider how gender norms, roles and relations influence patterns of cannabis use to inform health promotion and prevention responses. Based on a scoping review on sex, gender and cannabis use, this article consolidates existing evidence from the academic literature on how gender norms, roles and relations impact cannabis-use patterns. Evidence is reviewed on: adherence to dominant masculine and feminine norms and cannabis-use patterns among adolescents and young adults, and how prevailing norms can be both reinstated or reimagined through cannabis use; gendered social dynamics in cannabis-use settings; and the impact of gender roles and relations on cannabis use among young adults of diverse sexual orientations and gender identities. Findings from the review are compared and contrasted with evidence on gender norms, roles and relations in the context of alcohol and tobacco use. Recommendations for integrating gender transformative principles in health promotion and prevention responses to cannabis use are provided.
