Abstract:
Canada is experiencing an ongoing overdose crisis, driven by a toxic unregulated drug supply. Integrated safer supply pilot programs offer pharmaceutical alternatives, coupled with comprehensive support services, to individuals using unregulated drug supply who are at high risk of overdose. We collected data from December 2020 to January 2023 on clients receiving safer opioid supply from five frontline service providers in Toronto, Canada, using interviewer-administered questionnaires. We assessed the incidence rate ratio of self-reported overdose comparing pre- and post-enrolment in the programs and examined changes in the prevalence of social and substance use outcomes post-enrolment. Forty-one participants were recruited, of whom 26 were followed up for a median of eight months (interquartile range, 5.0-11.7). The incidence rate ratio of overdose comparing post-enrolment to pre-enrolment was 0.20 (95% confidence interval, 0.09-0.43). Participants reported several positive social and substance use outcomes at follow-up, including a reduction in reliance on the unregulated supply and reduced criminal activity. Future implementation of integrated safer opioid supply pilot programs with larger sample sizes and rigorous epidemiological designs could help further illustrate the potential impacts of these programs in reducing overdose rates in Canada.

Insights
Safer supply programs in Toronto significantly reduced overdose rates by 80% among high-risk individuals. These integrated programs also decreased reliance on unregulated drugs and reduced criminal activity.
Area of Science:
- Public Health
- Epidemiology
- Addiction Medicine
Background:
- Canada faces a critical overdose crisis fueled by an illicit drug supply.
- Safer supply programs provide pharmaceutical alternatives and support to at-risk individuals.
Observation:
- Data collected from December 2020 to January 2023 from five Toronto service providers.
- 26 participants were followed for a median of eight months.
Findings:
- A significant 80% reduction in overdose incidence rate ratio post-program enrollment (0.20, 95% CI 0.09-0.43).
- Participants reported decreased reliance on unregulated drugs and reduced criminal activity.
Implications:
- Integrated safer opioid supply programs show promise in mitigating overdose deaths.
- Further research with larger samples and robust designs is warranted to confirm impacts.
