The Detection of Novel Nitazene‐Class Opioids in Unregulated Drug Markets in Canada
Temporal and regional associations between fentanyl concentrations in the unregulated drug supply and drug-related mortality in British Columbia, Canada
Quantifying fentanyl concentrations from point-of-care drug checking data enables detection of geographic and temporal patterns in the unregulated drug supply and their associations with drug-related mortality. This approach offers a tool for harm reduction, drug supply monitoring, and policy response during the ongoing drug toxicity crisis
Applying a Modified Version of the Prediction of Alcohol Withdrawal Severity Scale in a Canadian Community Withdrawal Management Setting
Sharing drug checking results in a Canadian setting: A multi-site analysis
This study revealed that over half the study sample shared their drug checking results with others, with results sharing being positively associated with recent drug dealing, frequent DCS utilisation, employment and ethnicity. Drug checking results were most often shared with friends, family and drug dealers. These findings extend the evidence base of DCS as a harm reduction tool by demonstrating how engagement with DCS facilitates information di…
Novel adulterants in unregulated opioids and their associations with adverse events
Non-fatal AE associated with unregulated opioids have been largely undescribed. Our findings report specific AE associated with different adulterants in the unregulated opioid supply. With this information, tailored public health interventions and services focused on these adulterants can be developed
Motivators of and barriers to drug checking engagement in British Columbia, Canada: Findings from a cross-sectional study
Drug checking uptake remains low in British Columbia, however this study identified desire for services among participants, suggesting a need for expanded drug checking services. Behavioral change was reported among a high proportion of people who said they would not use their drugs if they tested positive for fentanyl, meaning that immunoassay strips alone have utility in the context of a pervasive fentanyl supply
Opportunities and challenges for implementing drug checking services in British Columbia, Canada: A qualitative study
Alongside structural reforms that address the underlying contextual factors that influence implementation (e.g., decriminalization of drugs, increased funding for DCS), centering community expertise throughout implementation is critical to the success of DCS. Our findings provide important insights into how BC can successfully implement systems-level harm reduction interventions and offer insights for other jurisdictions in their implementation o…

Precarious Housing Associated with Unsuppressed Viral load, sub-optimal Access to HIV Treatment and Unmet Health care Needs, Among Women Living with HIV in Metro Vancouver, Canada
Using passive surveillance technology for overdose prevention: Key ethical and implementation issues
Passive surveillance technology has the potential to increase safety through monitoring spaces where people are at risk of overdose. One key opportunity for the use of passive surveillance technology to prevent overdose fatality is in bathrooms where people may be using drugs. However, uncertainty remains with regards to how to attain informed consent, implications for data storage and privacy and potential negative socio‐legal ramifications for …
The prevalence and social-structural correlates of housing status among women living with HIV in Vancouver, Canada
Complex social-structural inequities are associated with housing instability among WLWH. In addition to meeting basic needs for living, to facilitate access to housing among WLWH, housing options that are gender-responsive and gender-inclusive and include trauma- and violence-informed principles, low-barrier requirements, and strong connections with supportive harm reduction services are critical

Migration Patterns from an Open Illicit Drug Scene and Emergency Department Visits among People Who Use Illicit Drugs in Vancouver, Canada
BACKGROUND: People who use illicit drugs (PWUD) experience various adverse health outcomes leading to increased healthcare service utilization. PWUD are also a highly mobile population which poses challenges to healthcare delivery. The objective of this study was to identify migration patterns from the Downtown Eastside (DTES), an urban illicit drug scene in Vancouver and to estimate the impact of different migration patterns on two outcomes: a) …

Behavioural, social and structural-level risk factors for developing Aids among HIV-positive people who use injection drugs in a Canadian setting, 1996–2017
People who use injection drugs (PWID) experience high rates of HIV acquisition and, as a result of lower rates of optimal access and adherence to combination antiretroviral therapy (ART), experience worse HIV treatment outcomes than other key affected populations. However, the incidence and risk factors for the development of AIDS among HIV-positive PWID have not been completely described. We used data from a community-recruited prospective cohor…

The effect of injecting alone on the use of drug checking services among people who inject drugs
Novel adulterants in unregulated opioids and their associations with adverse events
Non-fatal AE associated with unregulated opioids have been largely undescribed. Our findings report specific AE associated with different adulterants in the unregulated opioid supply. With this information, tailored public health interventions and services focused on these adulterants can be developed
Will peer-based interventions improve hepatitis C virus treatment uptake among young people who inject drugs
HIV testing and willingness to get HIV testing at a peer-run drop-in centre for people who inject drugs in Bangkok, Thailand
More than three-quarters of IDU received HIV testing in the previous six months. However, HIV risk behaviour was common among those who had not been tested. Additionally, 74.2% of participants were willing to receive HIV testing at the MSHRC. These findings provide evidence for ongoing HIV prevention education, as well potential benefits of incorporating HIV testing for IDU within peer-led harm reduction programs
HIV Test Avoidance Among People Who Inject Drugs in Thailand
Case identification is a key component of HIV prevention efforts; yet rates of HIV testing remain low in some settings. We explored factors associated with HIV test avoidance among people who inject drugs (IDU) in Thailand. Between July and October 2011, 350 Thai IDU participated in the study. In bivariate analyses, male gender, high intensity drug use, syringe sharing, increased police presence, and being refused healthcare services were positiv…
Reports of police beating and associated harms among people who inject drugs in Bangkok, Thailand: A serial cross-sectional study
A high proportion of IDU in Bangkok reported having been beaten by the police. Experiencing police beating was independently associated with various indicators of drug-related harm. These findings suggest that the over-reliance on enforcement-based approaches is contributing to police-perpetrated abuses and the perpetuation of the HIV risk behaviour among Thai IDU
The Effect of Exposures to Policing on Syringe Sharing Among People Who Inject Drugs in Bangkok, Thailand
Police confrontations among street-involved youth in a Canadian setting
Childhood Sexual Abuse and Syringe Sharing Among People Who Inject Drugs

Willingness to engage in peer-delivered HIV voluntary counselling and testing among people who inject drugs in a Canadian setting
BACKGROUND: People who inject drugs (IDU) face unique systemic, social and individual barriers to conventional HIV voluntary counselling and testing (VCT) programmes. Peer-delivered approaches represent a possible alternative to improve rates of testing among this population. METHODS: Cross-sectional data from a prospective cohort of IDU in Vancouver, Canada, were collected between December 2011 and May 2012. Bivariate statistics and multivariate…
Police interference with methadone treatment in Bangkok, Thailand
Leaving the Hospital Against Medical Advice Among People Who Use Illicit Drugs: A Systematic Review
Background. Leaving the hospital against medical advice is an increasing problem in acute care settings and is associated with an array of negative health consequences that may lead to readmission for a worsened health outcome or mortality. Leaving the hospital against medical advice is particularly common among people who use illicit drugs (PWUD) and has been linked to a number of complex issues; however, few studies have focused specifically on…
Risky and rushed public crack cocaine smoking: The potential for supervised inhalation facilities
A high prevalence of public crack smoking and rushed public crack smoking was observed in this setting. These findings point to the need for implementing and evaluating evidence-based public health interventions, such as supervised inhalation facilities, to reduce the risks and harms associated with smoking crack in public
Knowledge translation to advance evidence-based health policy in Thailand
Significant gaps between scientific evidence and policy have resulted in growing interest in the role that knowledge translation (KT) can play in informing evidence-based policy. The Mitsampan Community Research Project, in consultation with the local community of people who inject drugs, developed a comprehensive KT strategy that aimed to translate research into policy related to HIV and illicit drug use in Bangkok, Thailand. Though barriers to …

Hepatitis C treatment among incarcerated individuals in Canada and strategies to prevent reinfection in the postrelease period
It is well-recognised that individuals incarcerated are disproportionally affected by hepatitis C viral (HCV) infections across Canada.1 Accordingly, in 2017, Correctional Service Canada (CSC) announced increased funding for treatment initiation among the estimated 2700 HCV infected individuals in federal prison settings.2 In April and May 2017, approximately 121 federal inmates were initiated on HCV treatment. This compares to an estimated 606 f…
