Opioid-Related Research

Opioids are a group of prescription drugs used to treat pain conditions; however the efficacy and safety of their use in treating chronic non-cancer pain has been widely questioned due to a lack of long-term studies, the availability of various opioid types and potencies on the market, and uncertainty on appropriate dosing. Given that Canada and the United States have the highest per capita consumption of opioids worldwide, this area required further evidence.

The ODPRN has conducted several population-based studies on the safe and appropriate use of opioids in Ontario by investigating the overall trends and geographic variation in opioid prescribing and related deaths, and the impact of policy and education interventions on important patient outcomes.

Lives lost to opioid toxicity among Ontarians who worked in the construction industry

Ontario continues to face a rapidly growing opioid overdose crisis. Our previous report found that in 2021, among people who died of opioid toxicity, one-third of those who were employed at the time of death worked in the construction industry.

This new report, Lives lost to opioid toxicity among Ontarians who worked in the construction industry, from the ODPRN, the Office of the Chief Coroner for Ontario/Ontario Forensic Pathology Service (OCC/OFPS) and Public Health Ontario (PHO), provides information on the disproportionate impact of opioid toxicity deaths among people working in the construction industry in Ontario. The report calls for industry-level responses in the construction industry that recognize the stigma around drug use, which may make people less likely to engage in treatment and harm reduction services offered through their employer.

Below is a support resource for individuals in the construction industry interested in learning more about tips for safer drug use and treatment options
