Ontario is in the midst of a drug crisis. These seven charts tell us who’s being hit hardest

Lead author Tonya Campbell

Tonya Campbell, PhD candidate at MAP, spoke with the Toronto Star about new research highlighting the disproportionate impact that opioid overdoses are having on Black, Asian and Latin American drug users. “These findings highlight that more research is needed to understand the crisis among racialized people, and they also emphasize that racialized communities need to have these long overdue conversations around drug use and surrounding stigma,” says Campbell.

Two new research chairs appointed at MAP

Two MAP scientists, Drs. Flora Matheson and Dan Werb, have recently been appointed five-year research chairs by Unity Health Toronto and the University of Toronto.

Dr. Flora Matheson has been named the St. Michael’s Hospital Chair in Homelessness, Housing and Health. She leads the Justice and Equity Lab, housed at MAP, where she investigates the links between health and criminalization/the justice system and examines risk factors for imprisonment. She was one of the first researchers in Canada to investigate and measure the strong relationship between problem gambling and homelessness. She and Good Shepherd Ministries co-developed and launched the first gambling-addiction program for people experiencing homelessness. Learn more about Dr. Matheson’s research

Dr. Dan Werb has been named the St. Michael’s Hospital Chair in Mental Health and Substance Use Disorders. He leads the Centre on Drug Policy Evaluation at MAP, which conducts extensive epidemiologic, implementation and policy research on addictions and drug policy, and works closely with governments, affected communities and civil society to guide effective and evidence-based policy responses to substance use. Dr. Werb has devoted his career to the development of effective solutions to protect health and human rights among communities affected by drug use. Learn more about Dr. Werb’s research

Dr. Sean Rourke spoke with CBC about the value and importance of making harm reduction supplies available via Our Healthbox. “If we’re reaching the right people and knowing what their needs are — knowing how those are changing in a particular community — that information is really helpful for an agency to know who you’re helping and who you’re not,” Rourke said.

Rising opioid overdose deaths among racialized groups in Ontario show need for targeted public health initiatives 

A new study published in BMJ Public Health by MAP Centre for Urban Health Solutions at St. Michael’s Hospital found stark differences between ethno-racial groups in Ontario when looking at circumstances surrounding opioid overdose deaths, as well as in the use of harm reduction tools and access to treatment.

The researchers looked at medical coroners’ data of individuals who died of accidental overdose in Ontario between July 1, 2017 and June 30, 2021. Some of the circumstances examined include the types of opioid and non-opioid substances involved, the incident location, and the prevalence of naloxone use. The study found that opioid-related harms have been increasing among racialized people in Ontario, and there were considerable disparities in access to treatment for opioid use disorder and in the administration of naloxone, particularly among Black Ontarians. Deaths among racialized people had a particularly large burden on young males, approximately half of whom did not have a diagnosis of opioid use disorder prior to death.

“We are in the midst of a toxic drug crisis that claims the lives of 22 Canadians every day,” explains lead author Tonya Campbell. “This paper calls attention to the stark differences in trends, patterns, and circumstances in opioid toxicity deaths across ethno-racial groups in a Canadian context.”

Key findings include:

  • White people accounted for the highest proportion of opioid overdose deaths.
  • Opioid overdose deaths among Asian and Latin American people increased considerably and remained relatively stable among Black people.
  • Relative to White people, deaths among racialized people in Ontario were more likely to arise from the use of non-pharmaceutical opioids.
  • Black and Asian people were less likely than White people to receive naloxone during the resuscitation attempt, despite a similar chance of a bystander being present at the time of the overdose.
  • Among those with opioid use disorder, racialized people, particularly Black people, were considerably less likely to receive opioid agonist treatment compared to White people.
  • Compared to White people, opioid-related deaths among Black and Asian Ontarians more frequently involved cocaine.
  • Across all groups, most people had a healthcare encounter for a mental health-related diagnosis in the 5 years preceding death.

“Taken together, these findings highlight the need for racialized people, who have historically been excluded from conversations about the crisis, to be actively integrated into the development of policies, programs, and strategies to address the toxic drug crisis,” said Campbell.

‘We’re losing people every day’: Dr. Tara Gomes on Ontario’s drug-toxicity crisis

A new study led by Dr. Tara Gomes shows that nearly two-thirds of people who died from substance-related toxicities between 2018 and 2022 had previous encounters with the health-care system for substance-use disorders. Dr. Gomes spoke with TVO about the rise in deaths during the pandemic, the current state of the overdose crisis, and what needs to change to connect people with the right treatments in hospital and in the community.
