Reclaiming Indigenous Identities: Culture as Strength Against Suicide Among Indigenous Youth in Canada
In Canada, Indigenous youth suicide represents one of several health disparities burdening Indigenous populations, and like many other of these disparities, can be understood as an expression of societal, historical, cultural and familial trauma. As the number of Indigenous youth who take their own lives every year in Canada continues to far exceed national averages, it appears that conventional suicide prevention efforts remain ineffective among this population. A growing body of research argues that conventional interventions, largely rooted in Western individual-level behavioural change frameworks, are culturally discordant with Indigenous paradigms. In response, some Indigenous communities are turning to cultural revitalization as a holistic community-driven response to suicide prevention and treatment. The following commentary explores the emerging evidence base for "culture as treatment" - a novel approach to suicide that emphasizes the significance of interconnectedness in healing, alongside the revitalization of traditional values to reclaim community wellness. In doing so, we seek to contribute to a changing discourse surrounding Indigenous youth suicide by acknowledging culture as strength against this national crisis
Unsafe Sexual Behaviour Associated with Hazardous Alcohol Use Among Street-Involved Youth
While risky sexual behaviours related to illicit drug use among street youth have been explored, the impacts of alcohol use have received less attention. This longitudinal study examined hazardous alcohol use among a population of street-involved youth, with particular attention to sexual and drug-related risk behaviours. Data were derived from the At-Risk Youth Study, a prospective cohort of street-involved youth in Vancouver, Canada. The outcome of interest was hazardous alcohol use defined by the US National Institute on Alcohol Abuse and Alcoholism. We used generalized estimating equations (GEEs) analyses to identify factors associated with hazardous alcohol use. Between 2005 and 2014, 1149 drug using youth were recruited and 629 (55%) reported hazardous alcohol use in the previous 6 months during study follow-up. In multivariable GEE analyses, unprotected sex (adjusted odds ratio [AOR] = 1.28, 95% confidence interval [95% CI] = 1.12-1.46) and homelessness (AOR = 1.35, 95% CI = 1.19-1.54) were independently associated with hazardous alcohol use (all p < .001). Older age (AOR = 0.95, 95% CI = 0.92 0.99), Caucasian ethnicity (AOR = 0.74, 95% CI = 0.61-0.90), daily heroin use (AOR = 0.53, 95% CI = 0.42 0.67), daily crack cocaine smoking (AOR = 0.73, 95% CI = 0.59-0.91), and daily crystal methamphetamine use (AOR = 0.52, 95% CI = 0.42-0.64) were negatively associated with hazardous alcohol use (all p < .05). In sub-analysis, consistent dose-response patterns were observed between levels of alcohol use and unprotected sex, homelessness, and daily heroin injection. In sum, hazardous alcohol use was positively associated with unsafe sexual behaviour and negatively associated with high-intensity drug use. Interventions to address hazardous alcohol use should be central to HIV prevention efforts for street-involved youth

Prescription opioid injection and risk of hepatitis C in relation to traditional drugs of misuse in a prospective cohort of street youth
Objective: Despite dramatic increases in the misuse of prescription opioids, the extent to which their intravenous injection places drug users at risk of acquiring hepatitis C virus (HCV) remains unclear. We sought to compare risk of HCV acquisition from injection of prescription opioids to that from other street drugs among high-risk street youth. Design: Prospective cohort study. Setting: Vancouver, British Columbia, Canada from September 2005 to November 2011. Participants: The At-Risk Youth Study (ARYS) is a prospective cohort of drug-using adolescents and young adults aged 14–26 years. Participants were recruited through street-based outreach and snowball sampling. Primary outcome measure HCV antibody seroconversion, measured every 6 months during follow-up. Risk for seroconversion from injection of prescription opioids was compared with injection of other street drugs of misuse, including heroin, cocaine or crystal methamphetamine, using Cox proportional hazards regression controlling for age, gender and syringe sharing. Results: Baseline HCV seropositivity was 10.6%. Among 512 HCV-seronegative youth contributing 860.2 person-years of follow-up, 56 (10.9%) seroconverted, resulting in an incidence density of 6.5/100 person-years. In bivariate analyses, prescription opioid injection (HR=3.48; 95% CI 1.57 to 7.70) predicted HCV seroconversion. However, in multivariate modelling, only injection of heroin (adjusted HR=4.56; 95% CI 2.39 to 8.70), cocaine (adjusted HR=1.88; 95% CI 1.00 to 3.54) and crystal methamphetamine (adjusted HR=2.91; 95% CI 1.57 to 5.38) remained independently associated with HCV seroconversion, whereas injection of prescription opioids did not (adjusted HR=0.94; 95% CI 0.40 to 2.21). Conclusions: Although misuse of prescription opioids is on the rise, traditional street drugs still posed the greatest threat of HCV transmission in this setting. Nonetheless, the high prevalence and incidence of HCV among Canadian street youth underscore the need for evidence-based drug prevention, treatment and harm reduction interventions targeting this vulnerable population
Regular MDMA Use is Associated with Decreased Risk of Drug Injection Among Street-Involved Youth Who Use Illicit Drugs.
OBJECTIVES:
Childhood trauma is common among street-involved youth and is associated with injection drug use. Illicit 3,4-Methylenedioxymethamphetamine (MDMA) use is also common among street-involved youth, and data suggest this substance has clinical utility in management of post-traumatic stress disorder (PTSD) and associated harms. Despite this, little is known about co-occurring patterns of MDMA use and injection drug use.
METHODS:
Data were derived from a prospective cohort of street-involved youth using illicit drugs in Vancouver, Canada. Using multivariable generalized estimating equation logistic regression, we examined the association between MDMA use and the use of injection drugs, adjusting for confounders such as polysubstance use and sociodemographic factors.
RESULTS:
4941 surveys from 1208 participants between September 2005 and May 2015 were included. Of these, 829 (68.6%) were male, 815 (67.5%) reported white ethnicity, and median age was 21.7 years. Overall, 599 (49.6%) participants reported MDMA use, 544 (45.0%) reported injection drug use, and 244 (20.2%) reported concurrent MDMA and injection drug use at least once during the study period. In multivariable analyses, regular MDMA use was significantly negatively associated with injection drug use (Adjusted Odds Ratio [AOR] = 0.57, 95% CI: 0.46-0.69).
DISCUSSION:
After accounting for socio-demographic factors and polysubstance use, periods of reported regular MDMA use were negatively associated with reported injection drug use among this cohort. These findings suggest that, unlike the use of most other non-injection drugs, illicit MDMA use does not appear to promote injection drug use but rather is associated with a reduced likelihood of injection drug use
Increasing Availability of Benzodiazepines Among People Who Inject Drugs in a Canadian Setting
Background: Benzodiazepine misuse is associated with mortality and is common among people who inject drugs (PWID). This study aimed to examine the temporal trends in the availability of benzodiazepines among PWID in a Canadian setting, and to identify factors associated with more immediate access to benzodiazepines.
Methods: Data were derived from three prospective cohorts of PWID in Vancouver, Canada, between June 2012 and May 2015. The primary outcome was the perceived availability of benzodiazepines, measured in three levels: not available, delayed availability (available in ≥10 min), and immediate availability (available in <10 min). We used multivariable generalized estimating equations to identify factors associated with availability of benzodiazepines.
Results: In total, 1641 individuals were included in these analyses. In multivariable analyses, factors associated with immediate benzodiazepine availability included incarceration (adjusted odds ratio (AOR): 1.42, 95% CI1.06, 1.89) and participation in methadone maintenance therapy (MMT) (AOR: 1.35, 95% CI 1.14, 1.60). Factors associated with delayed benzodiazepine availability included incarceration (AOR: 1.45, 95% CI 1.02, 2.07) and MMT (AOR: 1.77, 95% CI 1.48, 2.12). Benzodiazepine availability increased throughout the study period for both immediate (AOR: 1.14, 95% CI 1.10, 1.18 per 6-month follow-up period) and delayed availability (AOR: 1.17, 95% CI 1.12, 1.22 per 6-month follow-up period).
Conclusions: Among our sample of PWID, benzodiazepine availability is increasing and was associated with health and criminal justice system characteristics. Our findings indicate a need to examine prescribing practices and educate both PWID and healthcare providers about the risks associated with benzodiazepine use
Street-Involved Youth Engaged In Sex Work at Increased Risk of Syringe Sharing
Syringe sharing places street-involved young people at risk of acquiring HIV and hepatitis C. While markers of economic marginalization, such as homelessness, have been linked with syringe sharing and have led to targeted interventions, the relationship between syringe sharing and other markers of economic vulnerability, such as sex work, are not well documented among young people. This study examines whether those engaged in sex work are at increased risk of syringe borrowing and syringe lending among street-involved youth who use injection drugs in Vancouver, Canada. Between September 2005 and May 2014, data was collected from the At-Risk Youth Study (ARYS), a prospective cohort of street involved youth aged 14-26. Generalized estimating equations with a confounding model building approach was used to examine the relationship between sex work and syringe borrowing and lending. 498 youth reported injecting drugs at some point during the study period and were therefore included in the analysis. In multivariable analysis, youth who engaged in sex work were at an elevated risk of both syringe borrowing (Adjusted Odds Ratio (AOR) = 2.17, 95% Confidence Interval [CI] = 1.40-3.36) and syringe lending (AOR = 1.66, 95% CI = 1.07-2.59). Our study found that youth engaged in street-based sex work were at a significantly higher risk of both syringe borrowing and lending among youth who use injection drugs in Vancouver. Ready access to clean syringes, safer working conditions for sex workers to enable risk reduction measures, and increased access to addiction treatment are identified as promising opportunities for reducing syringe sharing in this setting

Cannabis use to manage opioid cravings among people who use unregulated opioids during a drug toxicity crisis.
BACKGROUND: Accumulating evidence has indicated that cannabis substitution is often used as a harm reduction strategy among people who use unregulated opioids (PWUO) and people living with chronic pain. We sought to investigate the association between cannabis use to manage opioid cravings and self-reported changes in opioid use among structurally marginalized PWUO. METHODS: The data were collected from a cross-sectional questionnaire administered to PWUO in Vancouver, Canada. Binary logistic regression was used to analyze the association between cannabis use to manage opioid cravings and self-reported changes in unregulated opioid use. RESULTS: A total of 205 people who use cannabis and opioids were enrolled in the present study from December 2019 to November 2021. Cannabis use to manage opioid cravings was reported by 118 (57.6%) participants. In the multivariable analysis, cannabis use to manage opioid cravings (adjusted Odds Ratio [aOR] = 2.13, 95% confidence interval [CI]: 1.07, 4.27) was significantly associated with self-reported reductions in opioid use. In the sub-analyses of pain, cannabis use to manage opioid cravings was only associated with self-assessed reductions in opioid use among people living with moderate to severe pain (aOR = 4.44, 95% CI: 1.52, 12.97). In the sub-analyses of males and females, cannabis use to manage opioid cravings was only associated with self-assessed reductions in opioid use among females (aOR = 8.19, 95% CI: 1.20, 55.81). CONCLUSIONS: These findings indicate that cannabis use to manage opioid cravings is a prevalent motivation for cannabis use among PWUO and is associated with self-assessed reductions in opioid use during periods of cannabis use. Increasing the accessibility of cannabis products for therapeutic use may be a useful supplementary strategy to mitigate exposure to unregulated opioids and associated harm during the ongoing drug toxicity crisis

Use of Cannabis as a Harm Reduction Strategy Among People Who Use Drugs: A Cohort Study.
Introduction: While substance use contributes to a substantial burden of disease, access to evidence-based harm reduction interventions remains limited or inaccessible. Preliminary research suggests that some individuals use cannabis to reduce the harms associated with their use of other substances, including opioids and stimulants. This study examines factors associated with the self-reported use of cannabis for harm reduction among people who use drugs (PWUD). Methods: We drew data from three prospective, community-recruited cohorts of PWUD in Vancouver, Canada, between June 2016 and May 2018. Multivariable generalized linear mixed-effects modeling was used to examine factors associated with the primary outcome of use of cannabis for harm reduction, defined as self-reported use of cannabis to substitute for other substances, treat withdrawal, or come down off other drugs. Results: One thousand nine hundred thirty-six participants contributed 5706 observations. In adjusted analyses, daily methamphetamine use (adjusted odds ratio [AOR]=1.43, 95% confidence interval [CI]: 1.09-1.89), experiencing barriers to accessing addiction treatment (AOR=1.92, 95% CI: 1.21-3.03), and enrollment in addiction treatment modalities other than opioid agonist therapy (AOR=1.64, 95% CI: 1.17-2.29) were positively associated with using cannabis for harm reduction. Older age was negatively associated (AOR=0.97, 95% CI: 0.95-0.98). Among 1281 (66.2%) participants who use cannabis, daily cannabis use and obtaining cannabis from unregulated dispensaries were also independent correlates of using cannabis for harm reduction. Discussion and Conclusions: Individuals who were more likely to use cannabis for harm reduction reported difficulty accessing addiction treatment or used substances, such as methamphetamines, where effective treatments are limited. These findings highlight the need to better understand the potential harm-reducing impacts of cannabis among PWUD in these scenarios
Homelessness and Incarceration Associated With Relapse into Stimulant and Opioid Use among Youth Who Are Street-Involved in Vancouver, Canada
Introduction and Aims: While much research has sought to identify the factors associated with initiation and cessation of various forms of drug use among vulnerable youth, little is known about relapse into drug use in this population. We sought to characterize relapse into stimulant and opioid use among street-involved youth in Vancouver, Canada.
Design and Methods: Data were collected between 2005 and 2017 from the At-Risk Youth Study (ARYS), a prospective cohort study of street-involved youth who use illicit drugs in Vancouver. Multivariable extended Cox regression was utilized to identify factors associated with relapse into harder drug use among youth who had previously ceased using stimulants and/or opioids for six months or longer.
Results: Among 246 participants who reported a period of cessation lasting six months or longer, 165 (67.1%) relapsed at some point during study follow-up. Youth who were recently incarcerated (adjusted hazard ratio [AHR]: 1.47), homeless (AHR: 1.40), or had a history of daily stimulant use (AHR: 1.64) were significantly more likely to report relapse, while youth of who identified as white (AHR: 0.78) were significantly less likely to report relapse (all p <0.05).
Discussion: Relapse into harder drug use was common among youth in our setting, and incarceration, homelessness, and daily stimulant use (pre-cessation) were found to be positively associated with relapse among street-involved youth.
Conclusions: Findings suggest that increased access to youth housing supports and alternatives to the criminalization of drug use may help to reduce the rates of relapse into harder drugs in this population
