The CDPE strives to improve community health and safety by conducting research and outreach on best practices in drug policy. We work collaboratively with governments, affected communities, and civil society to guide effective and evidence-based policy responses to substance use.
The CDPE was founded as the International Centre for Science in Drug Policy (ICSDP) in 2010 at the BC Centre for Excellence in HIV/AIDS in Vancouver, Canada. The CDPE is now housed within the Li Ka Shing Knowledge Institute at St. Michael’s Hospital, a site of Unity Health Toronto, in Toronto, Canada.
The CDPE endeavors to be a primary source for rigorous scientific evidence on the impacts of illegal drug policy on community health and safety. To that end, the CDPE produces research products that adhere to the highest standards of peer-reviewed scientific research. The CDPE also conducts outreach and knowledge translation to inform policymakers, affected communities, key stakeholders, and the general public on pressing current issues surrounding illegal drugs and drug policy. The CDPE also leads innovative primary research, including on drug checking services, supervised injection services, injection drug use prevention, overdose response, and drug policy evaluation.

Zachary Bouck is a Research Associate at the CDPE, where he assists with study design, data analysis and interpretation of findings. Zach has prior experience working as a biostatistician at Women’s College Hospital, where the majority of his research involved the use of administrative data to study physician and system-level characteristics associated with use of low-value care. His interest at CDPE is studying persons who inject drugs (PWID) within the Ontario integrated Supervised Injection Site (OiSIS) prospective cohort to identify characteristics associated with providing injection initiation assistance to injection-naive individuals. He is currently a PhD in Epidemiology at the Dalla Lana School of Public Health at the University of Toronto and holds a Masters of Public Health from the University of Saskatchewan.

Dr. Bowles’ dissertation was entitled “Opioid Overdose Among Persons Who Inject Drugs in Philadelphia: Witnessed Overdose Responses, Prevention Program Diffusion, and Environmental Risks.” Following successful defence of her dissertation, she accepted an NIH-funded T32 Postdoctoral Scholarship at the University of California San Diego.
Dr. Gillian Kolla is a Postdoctoral Fellow at the CDPE. She uses community-based qualitative and ethnographic research to examine how to make health and social services more accessible to people who use drugs. Dr. Kolla’s doctoral research at the Dalla Lana School of Public Health, University of Toronto, explored how the criminalization of drug use impedes the ability of public health programs to respond effectively to drug use. She is currently also conducting postdoctoral research at the Canadian Institute for Substance Use Research at the University of Victoria, and is a member of the coordinating committee for the Toronto Overdose Prevention Society, which opened and ran Ontario’s first supervised injection site in Moss Park as a volunteer initiative in 2017-2018 as part of a community-led response to overdose deaths.
