Abstract
To systematically review evidence evaluating cannabis-related knowledge and perception of risk in children and adolescents. We systematically searched Medline, PsycINFO, and EMBASE using Preferred Reporting Items for Systematic Reviews and Meta-Analyses methodology. 133 studies from around the world (including ages 10-18 yrs) met inclusion criteria, with 70% meeting grade 2C quality. Increased knowledge and perception of risk of cannabis frequently correlated with lower levels of current use and intent to use. Studies examining correlations over time generally demonstrated increased adolescent cannabis use and decreased perception of risk. Included prevention-based interventions often enhanced knowledge and/or perception of risk in adolescents exposed to the intervention. Studies exploring outcomes relating to legislative changes for recreational marijuana use demonstrated considerable heterogeneity regarding knowledge and perception of risk whereas studies that focused on medicinal marijuana legislative changes overwhelmingly demonstrated a decrease in perception of risk post legalization. Increased knowledge and perception of risk of cannabis in adolescents often correlate with lower levels of current use and intention to use in the future. Further study and implementation of public health and clinically-oriented strategies that seek to increase knowledge among youth about the potential health harms of cannabis use should continue and be prioritized.

Neurol Clin Pract 2023; 13:e200174. [PMID: 37251367 PMCID: PMC10219131 DOI: 10.1212/cpj.0000000000200174] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/29/2022] [Accepted: 04/03/2023] [Indexed: 05/31/2023]
Abstract
Background and Objectives Patients with epilepsy have long sought alternatives to conventional antiseizure medications (ASMs) for the treatment of their epilepsy and to improve the significant side effect burden of ASMs and comorbidities. It was established before the legalization of marijuana in Canada in 2018 that many patients with epilepsy use marijuana to treat their seizures or for recreational purposes. However, there exists no current data on the prevalence and habits of marijuana use in the Canadian epilepsy population since legalization. Methods We conducted a nationwide cross-sectional survey of patients recruited through health care providers or epilepsy organizations to investigate marijuana usage habits and perceptions. Results From 395 responses obtained through the survey, 221 responses stated that they used marijuana within the past year. A history of seizures for more than 10 years was noted in 50.7% (n = 148) patients with generalized seizures being the most common type (n = 169; 57.1%). Most of them (n = 154; 52.0%) had tried 3 or more ASMs, and 37.2% (n = 110) used various other treatments (ketogenic diet, vagus nerve stimulation, or resective surgery) indicating a proportion with drug-resistant epilepsy. This subgroup was more likely to have started using marijuana for drug-resistant epilepsy (p < 0.001). Current marijuana use for epilepsy management was endorsed by 47.5% (n = 116). Marijuana was "somewhat" to "very" effective at reducing seizure frequency for 60.1% (n = 123). The main side effects of marijuana were impaired thinking (n = 40; 17.17%), anxiety (n = 37; 15.74%), and altered hunger (n = 36; 15.32%). Marijuana was used at least once daily by 70.3% (n = 168) with the median amount per week being 5.0 g (IQR = 1-10), and the preferred method of consumption was smoking (n = 83; 34.7%). The participants expressed concerns regarding financial strain (n = 108; 36.5%), lack of recommendation from a doctor (n = 89; 30.1%), and lack of information (n = 56; 18.9%) surrounding marijuana use. Discussion This study reveals a high prevalence of marijuana use among patients with epilepsy living in Canada particularly when seizures are drug resistant. A significant proportion of patients reported improvement of seizures with marijuana use, consistent with previous studies. With the increased accessibility of marijuana, it is imperative that physicians are aware of marijuana usage habits among patients with epilepsy.

Abstract
INTRODUCTION Lower perceived risk is a well-established risk factor for initiating substance use behaviors and an integral component of many health behavior theories. Established literature has shown that many substance use behaviors are more prevalent among individuals who identify as lesbian, gay, or bisexual than among those who identify as heterosexual. However, potential differences in perceived risk by sexual identity among individuals with no lifetime use have not been well characterized to date. METHODS Data on 111,785 adults aged 18-34 years (including 11,377 lesbian, gay, and bisexual adults) were from the 2015-2019 National Survey on Drug Use and Health. Perceived risks (classified as great risk versus less than great risk) were assessed with 11 National Survey on Drug Use and Health survey items regarding 6 different substances (alcohol, cigarettes, marijuana, cocaine, lysergic acid diethylamide, and heroin). Survey-weighted and sex-stratified logistic regression models were used to estimate sexual identity differences regarding perceived great risk among those reporting no lifetime use. Analyses were conducted in 2021-2022. RESULTS Gay men, bisexual men, lesbian/gay women, and bisexual women were all significantly less likely than heterosexual peers to perceive great risk associated with specific marijuana, cocaine, lysergic acid diethylamide, and heroin use behaviors. Bisexual men and women were also significantly less likely than heterosexual peers to perceive great risk associated with binge drinking behaviors and smoking ≥1 packs of cigarettes daily. CONCLUSIONS This novel investigation among never users provides evidence that lesbian, gay, and bisexual adults perceive significantly lower risks associated with multiple substance use behaviors than heterosexual adults, which may indicate important sexual identity differences in susceptibility to substance use initiation.

Abstract
Le vapotage chez les jeunes comporte des risques importants pour la santé et la sécurité des enfants et des adolescents canadiens. Le présent document de principes fournit de l'information générale sur le vapotage et les produits et dispositifs qui y sont liés, traite des méfaits à court et à long terme associés à leur utilisation et propose des stratégies de prévention et d'abandon pour les jeunes vapoteurs ou ceux qui sont à risque de commencer à vapoter. Le vapotage chez les jeunes est associé à un risque accru d'usage de tabac et de substances psychoactives, de troubles de santé mentale, de pneumopathie, de cardiopathie et de blessures accidentelles. Le vapotage ne doit pas servir d'outil d'abandon du tabac chez les jeunes, en raison de son manque d'efficacité et des données probantes sur les méfaits qu'il occasionne. De nombreuses stratégies préventives et thérapeutiques utilisées pour l'abandon du tabac, y compris les stratégies comportementales et pharmacologiques, peuvent être adaptées pour aider les jeunes à arrêter de vapoter. Des recommandations sont formulées pour les intervenants communautaires et les décideurs.

Abstract
Youth vaping presents significant risks for the health and safety of Canadian children and adolescents. This statement provides background information about vaping, vaping products, and related devices, discusses the short- and long-term harms known to be associated with their use, and offers prevention and cessation strategies for youth who vape or are at risk for starting. Youth vaping is associated with increased risk for tobacco and other substance use, mental health problems, pulmonary and cardiovascular disease, and unintentional injuries. Vaping should not be used as a smoking cessation tool for youth, due to lack of effectiveness and evidence of harm. Many preventive and treatment strategies used for tobacco cessation, including behavioural and pharmacological options, can be adapted to help youth quit vaping. Recommendations for community stakeholders and policy makers are included.

Abstract
BACKGROUND While several health risks of e-cigarette and marijuana use have been described, little is known about their associations with school-related outcomes and risky sexual behaviors in adolescents. Objectives: To determine the odds of adverse school outcomes and risky sexual behaviors among youth with single or dual use of e-cigarettes and marijuana. Methods: We used data from the 2015 and 2017 waves of the Youth Risk Behavior Survey, a nationally representative survey of high school students in the US. Participants (N = 30,389) were divided into four exposure groups for single or dual use of e-cigarettes and marijuana. We compared rates of e-cigarette and/or marijuana use for different demographic characteristics using chi-square tests and performed multivariate logistic regressions exploring associations among e-cigarette and marijuana use and adverse school outcomes and risky sexual behaviors adjusting for confounding factors. Results: Participants reported e-cigarette-only (7.7%), marijuana-only (8.5%), and dual e-cigarette/marijuana (9.2%) use. Youth in all three use categories had higher odds of reporting grades that were mostly C's or lower than youth with no use, but no difference was found between youth with e-cigarette-only vs marijuana-only use. Increased odds of having sex without a condom were seen in youth with marijuana-only use (vs. e-cigarette-only use or no use) but not in youth with e-cigarette-only use or dual use. Conclusions: We found increased odds of adverse school-related outcomes and contrasting sexual risk profiles among youth with single or dual e-cigarette and marijuana use.

Chadi N, Winickoff JP, Drouin O. Parental Optimism and Perceived Control over Children's Initiation of Tobacco, Cannabis, and Opioid Use. INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:E6181.

Abstract
Families play an important role in helping teenagers avoid using tobacco, cannabis, and opioids, but some parents may underestimate the risk of their children using those substances. This study aimed to determine parents' perceived likelihood of their child initiating tobacco, cannabis, and opioid use, as well as the control they have in preventing their child from using those substances. We surveyed 427 parents of children aged 0-18 years old using the online Amazon Mechanical Turk platform in the spring of 2019. We measured participants' perceived likelihood of their child initiating tobacco, cannabis, or opioid use before the age of 18 compared to other children, using a five-point Likert scale. This perceived likelihood was dichotomized between optimistic (less likely than average) and non-optimistic (average or more likely than average). Independent variables included parental tobacco use, perceived parental control, and perceived severity of the behavior. Participants with missing data and participants with children who had already initiated substance use were excluded from statistical analyses. Mean age of participants was 38.1 years (Standard Deviation 8.4); 67% were female. Level of parental optimism was 59% for cannabis, 77% for tobacco, and 82% for opioids. Perceived severity was significantly lower for cannabis use (71/100) than tobacco (90/100) and opioid use (92/100) (p < 0.001). Current smokers were less likely than never smokers to be optimistic about their child's risk of initiating using tobacco (Adjusted Odds Ratio (AOR): 0.18 [95% Confidence Interval (CI) 0.10-0.34]) or cannabis (AOR: 0.21 [95% CI 0.12-0.38]). Parental perceived likelihood of a child initiating substance use represents an understudied and potential target for substance use prevention.
