Trends, characteristics, and circumstances surrounding stimulant toxicity deaths in Ontario, Canada from 2018 to 2021.

Introduction: As the drug toxicity crisis continues to evolve globally, harms related to non-opioid substances, including stimulants, have risen in parallel. Our study aims were to describe trends in accidental stimulant toxicity deaths and to characterize demographic characteristics of decedents and the circumstances surrounding death.

Methods: We conducted a population-based repeated cross-sectional study, of all accidental stimulant toxicity deaths between January 1, 2018, and December 31, 2021, in Ontario, Canada. We reported monthly rates of stimulant toxicity deaths per 100,000 people residing in Ontario and the circumstances surrounding death. All analyses were stratified by the type of stimulant(s) involved in death.

Results: Between 2018 and 2021, we identified 5210 stimulant toxicity deaths with the monthly rate rising from 0.4 to 1.0 per 100,000. Both cocaine and methamphetamine were involved in 16.2 % of deaths, and 56.2 % and 27.7 % involved cocaine or methamphetamine (without other stimulants), respectively. Over 80 % of deaths also involved an opioid. Among all deaths, 75.2 % of decedents were male, 53.1 % were aged 25-44, and over half of all deaths occurred in private residences (64.7 %).

Conclusions: The rate of stimulant toxicity deaths has continued to grow, more than doubling over a three-year period. As stimulant-related deaths continue to rise, comprehensive social supports and mental health services, including harm reduction and treatment programs adapted to the unique needs of people who use stimulants alone or in combination with other substances, are urgently required to meet the changing needs of people who use drugs.
