The Detection of Novel Nitazene‐Class Opioids in Unregulated Drug Markets in Canada
Looking through the cracks
BACKGROUND: Cocaine use is increasing worldwide, and Brazil, located along major transatlantic trafficking routes, has experienced widespread availability of low-cost crack, which circulates predominantly in open drug scenes (ODS). ODS are public spaces where drug use, purchase, sale, and social interaction converge. While national surveys have identified these settings as central to crack use, their social, structural, and spatial characteristic…
Police encounters among people who use drugs in Toronto, Canada
Framing decriminalization
These findings highlight critical gaps in government communication and the dominance of misrepresentative media framing in shaping public attitudes. Effective drug policy requires not only legislative change but also proactive, coordinated, and sustained public education strategies to counter misinformation, reduce stigma, and build lasting support
A scoping review and concept analysis to inform Canada’s safe(r) opioid supply research agenda
Safe(r) supply encompasses prescribed opioid alternatives interventions (safer supply) and non-medicalized (safe supply) approaches with shared antecedents but distinct attributes and consequences. This study highlights the need to better define and standardize the parameters of safer supply approaches, including population, dosing, and intended objectives, to enable a more precise assessment of their potential benefits and risks. This nuanced un…
Exploring unregulated substance use health data in Ontario, Canada
Canada’s overdose epidemic underscores the urgent need for high-quality, comprehensive, and timely national health data to inform evidence-based policies, population health management, and targeted intervention strategies. Using the province of Ontario, Canada, as a case study, this paper examines the current landscape of unregulated substance use health data, including both administrative and non-administrative health data sources. Health data o…
The impact of the Covid-19 pandemic on access to harm reduction and treatment services among people who inject drugs in Toronto, Canada
(230 words) The COVID-19 pandemic and related restrictions exacerbated Canada’s ongoing drug toxicity overdose crisis. Opioid agonist therapy (OAT), safer opioid supply (SOS), and supervised consumption sites (SCS) are interventions that aim to reduce risk of morbidity and mortality from drug toxicity and were affected by COVID-19. Between September and October 2020, we conducted qualitative interviews with 24 people who inject drugs receiving se…
Motivations for and perspectives of medication diversion among clients of a safer opioid supply program in Toronto, Canada
These findings document experiences of medication diversion and the multifaceted and complex interplay of various individual and contextual factors that motivate safer opioid supply clients to engage in it. Future policy and safer opioid supply practice should address root causes of diversion, particularly barriers to service access and the diverse medication needs of clients
Patterns of opioid toxicity deaths after the implementation of Covid-19 emergency measures in Ontario, Canada
The decriminalization of illicit drugs in British Columbia
This evaluation will draw on implementation science research practices to evaluate and understand the full impacts of this novel drug policy experiment. Results will be widely disseminated through manuscripts, reports, presentations, and infographics, which will be adapted and tailored for specific audiences. The protocol identifies several anticipated challenges and limitations. This evaluation's evidence-based findings will be poised to offer p…
Modeling the impact of a supervised consumption site on HIV and HCV transmission among people who inject drugs in three counties in California, USA
Our models suggest that SCS is an important intervention to enable HCV elimination and could help end the HIV epidemic among PWID in California. It could also have additional benefits such facilitating pathways into drug treatment programs and preventing fatal overdose
Latent polydrug use patterns and the provision of injection initiation assistance among people who inject drugs in three North American settings
Insights from Drug Checking Programs
The year 2021 was the most deadly year for overdose deaths in the USA and Canada. The stress and social isolation stemming from the COVID-19 pandemic coupled with a flood of fentanyl into local drug markets created conditions in which people who use drugs were more susceptible to accidental overdose. Within territorial, state, and local policy communities, there have been longstanding efforts to reduce morbidity and mortality within this populati…

Financial Vulnerability and Its Association with HIV Transmission Risk Behaviors Among People Who Inject Drugs in Kyrgyzstan
Challenges of implementing safer supply programs in Canada during the Covid-19 pandemic
Safer supply pilot programs in Canada face multiple inner and outer implementation challenges. Given the potential role of safer supply programs in addressing the drug toxicity crisis in Canada and the possibility of future scale-up, services should be well-supported during their implementation phases. Refining service provision within safer supply programs based on the feedback and experiences of clients and program administrators is warranted, …
Flawed reports can harm
Supervised consumption services have been scaled up within Canada and internationally as an ethical imperative in the context of a public health emergency. A large body of peer-reviewed evidence demonstrates that these services prevent poisoning deaths, reduce infectious disease transmission risk behaviour, and facilitate clients' connections to other health and social services. In 2019, the Alberta government commissioned a review of the socioec…

Examining the Spatial Distribution of Law Enforcement Encounters among People Who Inject Drugs after Implementation of Mexico’s Drug Policy Reform
The Ontario Integrated Supervised Injection Services Cohort Study of People Who Inject Drugs in Toronto, Canada (OiSIS-Toronto)
The Ontario Integrated Supervised Injection Services cohort in Toronto, Canada (OiSIS-Toronto) is an open prospective cohort of people who inject drugs (PWID). OiSIS-Toronto was established to evaluate the impacts of supervised consumption services (SCS) integrated within three community health agencies on health status and service use. The cohort includes PWID who do and do not use SCS, recruited via self-referral, snowball sampling, and communi…
Where Is the Opioid Use Epidemic in Mexico? A Cautionary Tale for Policymakers South of the US–Mexico Border
In North America, opioid use and its harms have increased in the United States and Canada over the past 2 decades. However, Mexico has yet to document patterns suggesting a higher level of opioid use or attendant harms. Historically, Mexico has been a country with low-level use of opioids, although heroin use has been documented. Low-level opioid use is likely attributable to structural, cultural, and individual factors. However, a range of dynam…

Institutional stakeholder perceptions of barriers to addiction treatment under Mexico's drug policy reform
Mexico has experienced disproportionate drug-related harms given its role as a production and transit zone for illegal drugs destined primarily for the USA. In response, in 2009, the Mexican federal government passed legislation mandating pre-arrest diversion of drug-dependent individuals towards addiction treatment. However, this federal law was not specific about how the scale-up of the addiction treatment sector was to be operationalised. We t…

The role of gender and power dynamics in injection initiation events within intimate partnerships in the US–Mexico border region
Women's initiation into injection drug use often establishes a pattern of risk following first injection. This study explored sources of gendered power dynamics in injection initiation experiences for people who inject drugs. A qualitative subsample from two prospective community-recruited cohorts of people who inject drugs in San Diego and Tijuana provided data on the contexts surrounding injection initiation processes. Intimate partnerships wer…
