Social Norms for Cannabis Use After Nonmedical Legalization in Canada. Am J Prev Med 2024; 66:809-818. [PMID: 38128676 DOI: 10.1016/j.amepre.2023.12.013] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 08/17/2023] [Revised: 12/15/2023] [Accepted: 12/15/2023] [Indexed: 12/23/2023]
Abstract
INTRODUCTION Social norms play an important role in cannabis use; however, there is little evidence on how social norms change in jurisdictions that legalize cannabis. This study examined trends in social norms before and after legalization of nonmedical cannabis in Canada in 2018. METHODS Data are from the International Cannabis Policy Study, a series of cross-sectional surveys conducted annually with Canadian respondents aged 16-65 years. Analyses were conducted in 2023 and included data from 58,045 respondents across 4 waves: the year immediately before legalization (2018) and 3 post-legalization waves (2019-2021). Regression models examined trends in injunctive norms (perceived approval of cannabis) and comfort in using cannabis in six different social contexts, adjusting for cannabis use frequency, medical authorization, and sociodemographic covariates. RESULTS Perceived social approval of cannabis use and comfort using cannabis in different social contexts was highest among males, frequent cannabis consumers, and those who reported medical authorization (p<0.05 in all cases). No changes in perceived approval were observed across years, except a temporary decrease in 2020 versus 2018 (OR=0.87, 95% CI=0.80, 0.95). Modest increases in comfort of using cannabis in 6 different social contexts were observed in 2019 (ß=0.10, p=0.001), 2020 (ß=0.10, p=0.001), and 2021 (ß=0.12, p<0.001) versus in 2018. CONCLUSIONS Social norms have remained relatively stable after nonmedical legalization in Canada, with only modest increases in comfort of using cannabis in different social settings. The findings may reflect widespread cannabis use in Canada prior to nonmedical legalization in 2018 as well as comprehensive restrictions on promotion and advertising.

Community-Based Prevention of Substance Use in Adolescents: Outcomes Before and During the COVID-19 Pandemic in Santiago, Chile. PREVENTION SCIENCE : THE OFFICIAL JOURNAL OF THE SOCIETY FOR PREVENTION RESEARCH 2024; 25:245-255.

Abstract
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 (X2 = 139.3, p < 0.01), past-month alcohol use decreased from 45.5 to 33.4% (X2 = 171.2, p < 0.01), and lifetime cannabis use decrease from 27.9 to 18.8% (X2 = 127.4, p < 0.01). Several risk factors improved between 2018 and 2020: staying out of home after 10 p.m. (X2 = 105.6, p < 0.01), alcohol use in friends (X2 = 31.8, p < 0.01), drunkenness in friends (X2 = 251.4, p < 0.01), and cannabis use in friends (X2 = 217.7, p < 0.01). However, other factors deteriorated in 2020: perceived parenting (X2 = 63.8, p < 0.01), depression and anxiety symptoms (X2 = 23.5, p < 0.01), and low parental rejection of alcohol use (X2 = 24.9, p < 0.01). The interaction between alcohol use in friends and year was significant for lifetime alcohol use (β = 0.29, p < 0.01) and past-month alcohol use (β = 0.24, p < 0.01), and the interaction between depression and anxiety symptoms and year was significant for lifetime alcohol use (β = 0.34, p < 0.01), past-month alcohol use (β = 0.33, p < 0.01), and lifetime cannabis use (β = 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).

Abstract
PURPOSE Youth with chronic medical conditions are vulnerable to unique alcohol-related health consequences, yet there are few prevention strategies targeting this group. Youth with chronic medical conditions parents' beliefs and provision of alcohol-related guidance have not yet been explored, which limits the development of effective family-based interventions. METHODS We evaluated baseline surveys of youth with chronic medical conditions and their parents (n = 268 dyads) enrolled in a randomized controlled trial of a psychoeducational intervention to reduce alcohol use by youth with chronic medical conditions. Surveys evaluated youth alcohol use, parent beliefs about their child's alcohol use, and parental provision of alcohol guidance, including disease-related and disease-independent (ie, "drinking and driving") topics. Paired bivariate tests (χ 2 , Fisher exact) were used to measure associations between youth with chronic medical conditions alcohol use and parent alcohol-related beliefs and provision of alcohol-related guidance. RESULTS In this study of 268 parent-youth dyads, many parents did not provide guidance on disease-specific topics, such as mixing alcohol with medications (47.8%) or risk of flares (37.6%). Furthermore, youth with chronic medical conditions whose parents had expectant beliefs about alcohol use (ie, alcohol use is "inevitable" or "OK with supervision") were more likely to report alcohol use (all P values <0.05). DISCUSSION These findings suggest parent beliefs may influence youth with chronic medical conditions alcohol use. Proactive, disease-specific education from medical providers to parents of youth with chronic medical conditions may help to reduce adverse consequences of alcohol use in these vulnerable youth.

Substance-Specific Risk Factors for Cannabis and Alcohol Use Among Young Adults Following Implementation of Nonmedical Cannabis Legalization. PREVENTION SCIENCE : THE OFFICIAL JOURNAL OF THE SOCIETY FOR PREVENTION RESEARCH 2023; 24:1047-1057. [PMID: 36114976 PMCID: PMC10020123 DOI: 10.1007/s11121-022-01435-8] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Accepted: 09/01/2022] [Indexed: 10/14/2022]
Abstract
Laws regarding cannabis are rapidly changing in the USA as more states legalize nonmedical cannabis for adults aged 21 and older. Previous research has examined whether legalization has led to an increase in cannabis use as well as the use of other substances. The current study examined changes in cannabis- and alcohol-specific risk factors following legalization of nonmedical cannabis. We used 6 years of annual cross-sectional data (2014-2019) from 12,951 young adults age 18 to 25 who resided in Washington state. Risk factors examined include perceiving that use was common among same-age peers, believing use was acceptable, having easy access, and low perceived physical and psychological harm from use. Logistic regression models estimated annual rate of increase in these risk factors. All cannabis-specific risk factors increased among those aged 21+ (range of ORs for annual rate of change: 1.07-1.31) while significant increase in cannabis-related risk factors among those under age 21 was limited to perceptions of cannabis use being common (medical use: OR=1.08, 95% CI: 1.03, 1.12; nonmedical use: OR=1.13, 95% CI: 1.08, 1.18) and low perceived physical harm of occasional use (OR=1.08, 95% CI: 1.03, 1.13). Although descriptive norms for past-year use of alcohol among those aged 21+ increased (OR = 1.09, 95% CI: 1.02, 1.17), other risk factors for alcohol did not change significantly or, in the case of low perceived physical and psychological harm, decreased among both those under age 21 and those aged 21+ (range of ORs = 0.90-0.94). Given these findings show an increase in cannabis-specific risk factors since legalization was implemented, particularly among those young adults aged 21+, preventive interventions correcting risk misperceptions and related risk factors among young adults aged 21+ may prove efficacious in reducing use and resultant negative consequences.

Direct and Indirect Effects of Cannabis Risk Perceptions on Cannabis Use Frequency. ADDICTION RESEARCH & THEORY 2023; 32:68-73. [PMID: 38268741 PMCID: PMC10805454 DOI: 10.1080/16066359.2023.2221029] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/09/2022] [Accepted: 05/24/2023] [Indexed: 01/26/2024]
Abstract
Background Perceived risk of harm associated with cannabis use has decreased in recent decades, particularly among emerging adults who show the highest prevalence of use. Cannabis-related protective behavioral strategies (PBS) are associated with lower cannabis use and fewer consequences; however, individuals who perceive using cannabis as low risk may use cannabis PBS less often. Therefore, using cross-sectional data, we examined the associations between perceived risk of harm associated with cannabis use, cannabis PBS, and cannabis use frequency. Method Participants were 146 emerging adults between the ages of 18-25 (56.2% female) who reported consuming cannabis at least 3 times/week and completed measures of past-month cannabis use, past three-month use of cannabis PBS, and perceived risk of harm associated with cannabis use. Path analyses examined direct and indirect effects of perceived risk of cannabis-related harm on cannabis frequency through cannabis PBS. Results Most (66.4%) participants reported no perceived risk of harm associated with occasional cannabis use, whereas 30.1% reported no perceived risk of harm associated with regular cannabis use. Findings indicated a significant indirect effect between perceived risk of harm and cannabis use frequency through cannabis PBS, b = -10.23, SE = 3.80, 95% CI [-17.67, -2.80], p = .007. Conclusions Among emerging adults who consume cannabis regularly, findings suggest that a greater perceived risk of cannabis-related harm is associated with decreased cannabis use frequency via increased use of cannabis PBS. Although future analyses evaluating causal mechanisms are needed, these findings have clinical implications for harm reduction interventions focused on cannabis use.

The influence of parent and peer disapproval on youth marijuana use mediated by youth risk perception: Focusing on the state comparison. Drug Alcohol Depend 2022; 240:109641. [PMID: 36179508 DOI: 10.1016/j.drugalcdep.2022.109641] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/30/2022] [Revised: 09/15/2022] [Accepted: 09/16/2022] [Indexed: 01/06/2023]
Abstract
BACKGROUND The prevention of youth marijuana use has become a national priority in the United States. This study examined the influence of parent and peer disapproval on youth marijuana use, mediated by youth risk perception. Because the legal status of marijuana use can influence individual perceptions of the drug, this study investigated differences in the mediating mechanism between youth living in states with medical marijuana legalization (MML) and those living in non-MML states. METHODS The 2019 National Survey of Drug Use and Health was used with a youth population aged 12-17 years (N = 2293). Structural equation modeling and bias-corrected bootstrapping were used to examine hypothesized path models and to evaluate the mediating effect of youth risk perception. RESULT Findings demonstrated that parent and peer disapproval significantly increased youth risk perception of marijuana and reduced youth marijuana use. Second, youth risk perception significantly mediated the association between parent and peer disapproval and youth marijuana use. Third, parent disapproval had a more significant direct effect on youth marijuana use, while peer disapproval had a more significant indirect effect on youth marijuana use via youth risk perception. Finally, the results showed a similar pattern in the mechanism between youths living in MML states compared with those in non-MML states in terms of significance and direction. CONCLUSION The findings suggested a need for improvements in marijuana related policies for both MML and non-MML states. Moreover, parent and peer focused strategies for education and prevention concerning marijuana use among youth are emphasized.

Substance-Specific Risk Factors among Young Adults: Potential Prevention Targets across Cannabis-Permissive Environments. Subst Use Misuse 2022; 57:1923-1930. [PMID: 36151975 PMCID: PMC9701568 DOI: 10.1080/10826084.2022.2120363] [Citation(s) in RCA: 2] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Indexed: 10/14/2022]
Abstract
PURPOSE This study examined levels of substance-specific risk factors such as perception of harm from substance use among young adults in a range of cannabis-permissive environments. The main objective was to inform future preventive interventions aimed at reducing cannabis use in the context of increasingly permissive environments. METHODS Data came from the Community Youth Development Study (CYDS) collected in 2016 when participants were about 23 years old (n = 1,722 participants residing in 46 U.S. states). Young adults self-reported their perceptions about the harms related to cannabis, alcohol, and cigarette use; attitudes about and ease of access to cannabis and other substances; and perceived wrongfulness and social acceptability of cannabis, alcohol, and cigarette use and of selling of cannabis and other illegal drugs. RESULTS Young adults in more permissive cannabis contexts reported higher levels of all cannabis-specific risk factors (e.g., greater access to and more favorable attitudes about cannabis use), except for perception of harm from regular cannabis use. However, permissiveness of the cannabis environment was not associated with heightened levels of risk factors for other substance use (such as alcohol, cigarettes, and opioids). CONCLUSIONS Future preventive interventions for young adults living in more permissive cannabis contexts may need to focus on cannabis-specific risk factors in particular and go beyond considerations of harm from regular use. Future studies should replicate these findings with other samples.

The reciprocal relationships of social norms and risk perceptions to cigarette, e-cigarette, and cannabis use: Cross-lagged panel analyses among US young adults in a longitudinal study. Drug Alcohol Depend 2022; 238:109570. [PMID: 35926300 DOI: 10.1016/j.drugalcdep.2022.109570] [Citation(s) in RCA: 11] [Impact Index Per Article: 5.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 02/23/2022] [Revised: 07/02/2022] [Accepted: 07/07/2022] [Indexed: 11/20/2022]
Abstract
INTRODUCTION Given the distinct and evolving social norms, research on health implications, and regulations regarding cigarettes, e-cigarettes, and cannabis, it is important to understand the interplay between social norms, risk perceptions, and use of these products. METHODS We analyzed 3 waves of longitudinal data (Fall 2018, 2019, 2020) from 3006 young adults (Mage=24.56, 54.8% female, 31.6% sexual minority, 39.6% racial/ethnic minority) from 6 US metropolitan statistical areas. Cross-lagged panel models (CLPMs) examined reciprocal relationships of (a) perceived social norms (i.e., peer use, social acceptability) and risk perceptions (i.e., harm, addictiveness) to (b) number of days of cigarette, e-cigarette, and cannabis use in the past 30 days, respectively. RESULTS At baseline, lifetime and past 30-day use prevalence was: 61.8% and 26.9% for cigarettes, 57.7% and 37.7% for e-cigarettes, and 70.7% and 39.2% for cannabis. Perceived social norms and use of cigarettes and e-cigarettes decreased over time, and risk perceptions increased (except cigarettes showed stable perceived harm). Regarding cannabis, perceived social norms and use increased, yet perceived harm and addictiveness also increased. CLPM indicated that greater perceived social norms predicted greater cigarette, e-cigarette, and cannabis use over time, and vice versa. While greater perceived risk predicted less e-cigarette and cannabis use and vice versa, this did not hold true for cigarettes: use predicted lower perceived risk, but risk perceptions did not predict later use. CONCLUSIONS Tobacco and cannabis intervention and regulatory efforts should address health risks of use, particularly of e-cigarettes and cannabis, as well as denormalizing use.

Adverse childhood experiences and past 30-day cannabis use among middle and high school students: The protective influence of families and schools. Addict Behav 2022; 130:107280. [PMID: 35279622 DOI: 10.1016/j.addbeh.2022.107280] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/13/2021] [Revised: 02/10/2022] [Accepted: 02/11/2022] [Indexed: 11/01/2022]
Abstract
Exposure to adverse childhood experiences (ACEs) is a risk factor for adolescent cannabis use (CU). We explored whether family communication and school connectedness can offer direct protection (the compensatory model of resiliency) or moderating protection (the protective factors model of resiliency). Using cluster random sampling, a Youth Risk Behavior Survey (YRBS) was conducted with 5,341 middle school and 4,980 high school students in 2019. Generalized estimating equations were used to estimate whether family communication and school connectedness offered independent direct protection (multiple regression) or moderating protection (multiplicative interaction) in the relationship between ACEs and past 30-day CU. Adjusted prevalence ratios (APR) and 95% confidence intervals (95% CI) were calculated. There was a graded relationship between ACEs and past 30-day CU for all students that was particularly strong among middle school students: 1 ACE (APR = 2.37, 95% CI = 2.16, 2.62), 2 ACEs (APR = 2.89, 95% CI = 2.60, 3.23), 3 ACEs (APR = 5.30, 95% CI = 4.75, 5.90), 4 + ACEs (APR = 7.86, 95% CI = 7.13, 8.67). Results supported the compensatory model of resiliency with both family communication (middle school APR = 0.90, 95% CI = 0.88, 0.93; high school APR = 0.90, 95% CI = 0.87, 0.93) and school connectedness (middle school APR = 0.76, 95% CI = 0.72, 0.79; high school APR = 0.72, 95% CI = 0.68, 0.77) demonstrating a direct, independent protective relationship with past 30-day CU. There was no consistent evidence supporting the protective factors resiliency model.

Abstract
Youth cannabis use is influenced by overlapping environmental contexts. We examined the associations between proximity to cannabis retailers and seeing cannabis advertisements and cannabis use behaviors in Oregon, a state with adult cannabis legalization. We used 2017 anonymous survey data from 24,154 Oregon 8th and 11th grade students. After adjustments for student and school district characteristics, advertising for 8th graders and presence of a retailer within a mile from school for 11th graders were associated with cannabis use and perceived harm. Additional policy efforts may further reduce youth exposure to cannabis.

Simultaneous use of marijuana and alcohol: Potential prevention targets among young adults who use alcohol. Addict Behav 2022; 124:107118.

Abstract
Simultaneous alcohol and marijuana use (SAM) such that their effects overlap has emerged as a behavior that is riskier than using either substance separately. It has been associated with high-risk binge drinking and driving while intoxicated during young adulthood, and it has been demonstrated to cause greater physical and mental impairment than use of alcohol or marijuana separately. To identify intervention and prevention targets specific to SAM, we examined the relationships between alcohol- and marijuana-specific beliefs and attitudes (risk factors) and self-reported SAM compared to non-simultaneous co-use (CAM) and alcohol use only in the past 30 days in a sample of young adults (n = 1,023, mean age = 23.17; SD = 0.43). Of those who reported drinking alcohol in the past 30 days, 20.7% reported SAM, 12.6% reported CAM, and 66.6% reported using only alcohol. Results from multinomial logistic regression analyses indicated that some marijuana-specific risk factors (e.g., belief that it is not at all wrong for someone their age to use marijuana) differentiated SAM or CAM from alcohol use only, but alcohol-specific risk factors generally did not. However, the perceptions that parents approved of their using marijuana or frequently drinking heavily were associated with a greater likelihood of SAM compared to CAM (OR ranged from 2.25 to 3.53). Findings point to the salience of individuals' attitudes and beliefs around marijuana use and their perception of parental approval of heavy drinking and marijuana use as potential targets for prevention programs targeting risk reduction among young adults.

Abstract
Background Drug abuse is detrimental, and excessive drug usage is a worldwide problem. Drug usage typically begins during adolescence. Factors for drug abuse include a variety of protective and risk factors. Hence, this systematic review aimed to determine the risk and protective factors of drug abuse among adolescents worldwide. Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) was adopted for the review which utilized three main journal databases, namely PubMed, EBSCOhost, and Web of Science. Tobacco addiction and alcohol abuse were excluded in this review. Retrieved citations were screened, and the data were extracted based on strict inclusion and exclusion criteria. Inclusion criteria include the article being full text, published from the year 2016 until 2020 and provided via open access resource or subscribed to by the institution. Quality assessment was done using Mixed Methods Appraisal Tools (MMAT) version 2018 to assess the methodological quality of the included studies. Given the heterogeneity of the included studies, a descriptive synthesis of the included studies was undertaken. Results Out of 425 articles identified, 22 quantitative articles and one qualitative article were included in the final review. Both the risk and protective factors obtained were categorized into three main domains: individual, family, and community factors. The individual risk factors identified were traits of high impulsivity; rebelliousness; emotional regulation impairment, low religious, pain catastrophic, homework completeness, total screen time and alexithymia; the experience of maltreatment or a negative upbringing; having psychiatric disorders such as conduct problems and major depressive disorder; previous e-cigarette exposure; behavioral addiction; low-perceived risk; high-perceived drug accessibility; and high-attitude to use synthetic drugs. The familial risk factors were prenatal maternal smoking; poor maternal psychological control; low parental education; negligence; poor supervision; uncontrolled pocket money; and the presence of substance-using family members. One community risk factor reported was having peers who abuse drugs. The protective factors determined were individual traits of optimism; a high level of mindfulness; having social phobia; having strong beliefs against substance abuse; the desire to maintain one’s health; high paternal awareness of drug abuse; school connectedness; structured activity and having strong religious beliefs. Conclusion The outcomes of this review suggest a complex interaction between a multitude of factors influencing adolescent drug abuse. Therefore, successful adolescent drug abuse prevention programs will require extensive work at all levels of domains.

Abstract
Early detection of risks for substance use disorders is essential to lifelong health and well-being for some youth. Very early-onset use is proposed as an indicator of risk for substance use disorders, but risk and protective factors related to early-onset use have not been identified. The current study compared risk and protective factors that distinguish early- and late-onset cannabis users from abstainers using data collected from a large community sample. The study also examined onset-group differences in participants’ reports of substance use disorder symptoms a decade later. Heavy episodic drinking (early-onset: OR = 7.29 CI = [1.60, 33.19]) and engagement with peers involved in deviant behaviors (early-onset: OR = 2.50 CI = [1.50, 4.13]) are risk factors for early-onset cannabis use. Protective factors, including parent monitoring (early-onset: OR = 0.73 CI = [0.58, 0.93]), engagement with peers involved in positive behaviors (early-onset: OR = 0.54 CI = [0.39, 0.76]), school engagement (early-onset: OR = 0.83 CI = [0.72, 0.96]), and academic grades (early-onset: OR = 0.37 CI = [0.21, 0.65]) also predicted early versus later onset-group differences. Early age of onset may be distinctly related to risk and protective factors previously associated with risks for substance use in all adolescents.

Abstract
AIMS The Communities That Care Youth Survey (CTCYS) is an assessment for youth risk and protective factors focused on antisocial behaviors, drug abuse, violence, and delinquency. The systematic review aimed to analyze psychometric validations and cross-cultural adaptation processes of CTCYS to prepare its Brazilian validation. METHODS PubMed, SpringerLink, Scopus, and Web of Science were the databases included. The study followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) protocol. RESULTS Twenty articles were selected based on the inclusion/exclusion criteria. In general, the construct validity indexes were considered adequate, and the measures of risk and protective factors were equivalent between ethnic groups, gender, and populations at risk. Reliability values for most scales are good, averaging about 0.78. We found cultural adaptations from six different countries with some satisfactory results, but not so good as the original properties of CTCYS and the adjustments to other ethnic groups or subpopulations in the United States. CONCLUSION This survey may be a potentially reliable and valid instrument to assess risk and protection in different cultures and populations. However, there is still a gap in the instrument's cross-cultural adaptation processes.

Abstract
American Indian (AI) youth residing on reservations report higher rates of marijuana use compared to national youth. Latent class analysis (LCA) was used to identify unique types of marijuana use among 2,884 AI high school students surveyed from 26 schools across six indigenous geographic regions. Predictors of class membership were then assessed using social, cultural, and individual measures relevant to adolescent substance use. Classes and predictors were examined separately for males and females. Four-class models fit the data best for both male and female AI students. Classes differed by sex, as did predictors. Overall, social predictors related to family and peers and the individual predictor, using marijuana to cope, were the best predictors of class membership. Based on these results, prevention and intervention efforts should provide alternative coping methods for these adolescents who often live in difficult situations, and should focus on encouraging parents to effectively monitor their adolescent children and communicate clear sanctions against marijuana use.

Factors related to an increase of cannabis use among adolescents in Chile: National school based surveys between 2003 and 2017. Addict Behav Rep 2020; 11:100260. [PMID: 32467849 PMCID: PMC7244907 DOI: 10.1016/j.abrep.2020.100260] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2019] [Accepted: 01/29/2020] [Indexed: 12/17/2022] Open
Abstract
Cannabis use in adolescents has more than doubled between 2003 and 2017 in Chile. Exact prevalence of substance use and effect size of associated factors are given. Strongest prevalence factors were friends who use cannabis and low perceived risk. Association of low parental rejection with cannabis use has increased. Tobacco and alcohol use remained strongly associated with cannabis use in adolescents.
Background Cannabis is the most commonly used illicit substance worldwide. In Chile, the prevalence of cannabis use among adolescents is the highest in the Americas. Our aim was to identify prevalence trends of cannabis use and associated factors in adolescents. Methods We performed multivariate logistic regression analyses of 416,417 cross-sectional school-based surveys of adolescents from 8th to 12th grade conducted between 2003 and 2017 in Chile. Cannabis use was the dependent variable. Age, gender, socio-economic variables, and factors on the individual, school and family level were assessed as independent variables. Results The prevalence of cannabis use in the past year increased from 13.6% in 2003 to 31.3% in 2017 in a linear trend (F(df:1,6) = 27.6; R2 = 0.79; p < 0.01). The strongest association with cannabis use was seen for having friends who regularly use cannabis, and low perceived risk of cannabis use. Between 2003 and 2017, the strength of association between the variable having friends who regularly use cannabis and cannabis use decreased from OR = 6.2 to OR = 2.9, in a significant linear trend (F(df:1,6) = 60.5; R2 = 0.89; p < 0.01); whereas the OR for low parental rejection of cannabis use with cannabis use increased in a linear trend (F(df:1,6) = 22.8; R2 = 0.75, p < 0.01) from OR = 1.2 to OR = 2.1. Conclusions Increasing cannabis use of adolescents in Chile requires adjustments of prevention strategies. Prevalence factors identified here constitute potential targets for interventions.

Abstract
Drug consumption is driven by a drug's pharmacological effects, which are experienced as rewarding, and is influenced by genetic, developmental, and psychosocial factors that mediate drug accessibility, norms, and social support systems or lack thereof. The reinforcing effects of drugs mostly depend on dopamine signaling in the nucleus accumbens, and chronic drug exposure triggers glutamatergic-mediated neuroadaptations in dopamine striato-thalamo-cortical (predominantly in prefrontal cortical regions including orbitofrontal cortex and anterior cingulate cortex) and limbic pathways (amygdala and hippocampus) that, in vulnerable individuals, can result in addiction. In parallel, changes in the extended amygdala result in negative emotional states that perpetuate drug taking as an attempt to temporarily alleviate them. Counterintuitively, in the addicted person, the actual drug consumption is associated with an attenuated dopamine increase in brain reward regions, which might contribute to drug-taking behavior to compensate for the difference between the magnitude of the expected reward triggered by the conditioning to drug cues and the actual experience of it. Combined, these effects result in an enhanced motivation to "seek the drug" (energized by dopamine increases triggered by drug cues) and an impaired prefrontal top-down self-regulation that favors compulsive drug-taking against the backdrop of negative emotionality and an enhanced interoceptive awareness of "drug hunger." Treatment interventions intended to reverse these neuroadaptations show promise as therapeutic approaches for addiction.

Abstract
ABSTRACT Objective: analyze the relationship between the perception of harm and benefits associated with the use of marijuana and its relation to real consumption, as well as the intention to use it in a context of regulatory changes, in young students, between 15 and 17 years old, of a public school in Bogota Colombia. Method: a quantitative, cross-sectional survey was carried out. 268 students in grade 9th to 11th from a public school in the city of Bogotá, Colombia participated of the study. Results: results reveled that there is an association between the perception of benefits and the consumption of marijuana. In addition, how a low perception of risk is associated with an intention to use in a context of legalization. Conclusion: this is one of the first studies in Colombia which explores the intention to use (at age 18) in a context of regulatory changes, as well as the attitude of young people towards the legalization of marijuana for medicinal and recreational use.
