Substance use and work
With the legalization of recreational cannabis in Canada, questions have been raised about patterns of cannabis use at work, the use of cannabis to treat work-related injuries, and the implications of such uses for work productivity, workplace health and safety and work disability management. IWH research examines these questions, as well as questions about the use and effectiveness of narcotics or opioids to treat pain, including pain associated with work injuries, and patterns of opioid-related harms among workers.

Cannabis use and perceptions among Canadian workers after legalization
Cannabis use for non-medical purposes became legal in Canada in October 2018. Many jurisdictions have followed suit in recent years. Although several studies have examined post-legalization outcomes in select groups and in the general population, data among the working population is lacking. Early results from an IWH study of Canadian workers suggested little change occurred in the year after legalization. In this presentation, Dr. Nancy Carnide shares findings from four waves of data, examining cannabis use patterns and perceptions from 2018 to 2021.

Exploring how workplace solutions can mitigate opioid harms among workers
With the recognition that workplaces can play a part in responding to North America’s opioid crisis, the OCRC and IWH brought together over 100 occupational health specialists, government representatives, union advocates, researchers, and others to discuss how to prevent opioid harms among workers. Presentations, panel discussions and breakout sessions provided a lot of food for thought about the way forward.

Formerly injured workers have higher risk of opioid-related harms than the general population in Ontario
An IWH study examined how opioid harms in a large group of formerly injured Ontario workers compared to harms in the general Ontario population. They found that the formerly injured workers had higher risks of emergency department visits and hospitalizations for opioid-related harms. This pattern was seen across most occupations and industries within this group of workers.

‘Unprecedented public health crisis’: Pioneering research studies links between workplaces, opioid harms
Dr. Nancy Carnide and Dr. Jeavana Sritharan were keynote presenters at the Opioids in the Workplace virtual event from OHS Canada and Talent Canada on Jan. 31 that attracted nearly 350 professionals. Their research, a collaborative effort between IWH and the Occupational Cancer Research Centre, offers a revealing look at the occupational patterns in opioid-related harms in Ontario and underscores the urgent need for intervention strategies tailored to the working population, writes Todd Humber.
