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

METHODS: Using a standardized prospective data collection protocol, we measured injection-related public orde…
Displacement of Canada's largest public illicit drug market in response to a police crackdown
BACKGROUND: Law enforcement is often used in an effort to reduce the social, community and health-related harms of illicit drug use by injection drug users (IDUs). There are, however, few data on the benefits of such enforcement or on the potential harms. A large-scale police "crackdown" to control illicit drug use in Vancouver's Downtown Eastside provided us with an opportunity to evaluate the effect. METHODS: As part of our ongoing prospective …
Harm reduction in prisons: A ‘rights based analysis’
Throughout most of the world, the primary response to problems associated with illicit injection drug use has been to intensify law enforcement efforts. This strategy has contributed to an unprecedented growth in prison populations and growing concerns regarding drug-related harm within prisons. Despite the presence of international laws and guidelines that call for the protection of the health of prisoners, prison authorities have generally been…
