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
Emergence of Medetomidine in the Unregulated Drug Supply and Its Association With Hallucinogenic Effects
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
Local Impact From International Crises: Unregulated Drug Toxicity During the Covid-19 Pandemic in British Columbia, Canada
Examining fentanyl and its analogues in the unregulated drug supply of British Columbia, Canada using drug checking technologies
Changes in the unregulated opioid drug supply during income assistance payment weeks in Vancouver, Canada: An exploratory analysis
Detection of synthetic cannabinoid adulteration in the unregulated drug supply in three Canadian settings
An outbreak of novel psychoactive substance benzodiazepines in the unregulated drug supply: Preliminary results from a community drug checking program using point-of-care and confirmatory methods
