Samuel Tobias completed his PhD at the University of British Columbia’s School of Population and Public Health with the BC Centre on Substance Use. He is an experienced drug-checking technician who, in his role as Research Data Coordinator for the BC Centre on Substance Use’s Drug Checking Project, oversaw the collection and reporting of drug-checking data across the province. Samuel is an applied epidemiologist focused on generating timely, actionable evidence to respond to the unregulated drug supply and reduce drug-related harms. His research examines how the composition of the unregulated drug supply evolves over time and what those changes mean for the health of people who use drugs.
