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.

Opioid-related deaths between 2019 and 2021 across 9 Canadian provinces and territories.

Background: The drug toxicity crisis continues to accelerate across Canada, with rapid increases in opioid-related harms following the onset of the COVID-19 pandemic. We sought to describe trends in the burden of opioid-related deaths across Canada throughout the pandemic, comparing these trends by province or territory, age, and sex.

Methods: We conducted a repeated cross-sectional analysis of accidental opioid-related deaths between Jan.

Trends in opioid toxicities among people with and without opioid use disorder and the impact of the COVID-19 pandemic in Ontario, Canada: A population-based analysis.

Background: Across Canada, the COVID-19 pandemic occurred amidst an ongoing drug toxicity crisis. Although elevated rates of substance-related harms have been observed nationally, it remains unknown if the pandemic state of emergency led to disproportionate increases in opioid toxicities among people with opioid use disorder (OUD) compared to those without.

Methods: We conducted a population-based repeated cross-sectional time series analysis of fatal and non-fatal opioid toxicities between January 1, 2014, and December 31, 2021, in Ontario, Canada.

Prescribed safer opioid supply: A scoping review of the evidence.

Background: Safer opioid supply programs provide prescription pharmaceutical opioids, often with supportive services, to people at high risk of experiencing harms related to substance use. However, questions regarding the effectiveness and safety of this practice remain. We conducted a scoping review of literature describing client outcomes from formal opioid supply programs providing prescriptions for pharmaceutical opioids, and the perceptions of involved clients/providers.

Assessing the impact of the slow-release oral morphine drug shortages in Ontario, Canada: A population-based time series analysis.

Background: Slow-release oral morphine (SROM) is used to manage pain, and as opioid agonist treatment (OAT). Between 2017 and 2021 in Canada, several drug shortages occurred for Kadian© (SROM-24). The purpose of this study was to evaluate the impact of these shortages on people's ability to remain on this medication.
