The economic costs of substance use in Canada (CSUCH)

Funding bodies

Health Canada and Canadian Centre on Substance Use and Addiction (CCSA)


Also known as the Canadian Substance Use Costs and Harms (CSUCH) study, this project aims to update estimates last made for Canada in 2006 by Rehm et al. We will update methods and data sources and, as well, provide detailed estimates for all Canadian jurisdictions, including the territories. A further refinement will be making cost estimates for 8 categories of psychoactive substance, namely, alcohol, tobacco, cannabis, opioids, other CNS depressants, cocaine, other CNS stimulants type plus ‘other drugs’. The work is funded by a grant from Health Canada's Substance Use and Addiction Program, held by CCSA. The results are available on an interactive website as well as through a report.

Progress to date

The team has completed new cost estimates for the years 2007-2020, which was released in March 2023.
