“Opioids have a place in clinical practice, but it’s really about making sure that when they are accessed, [...] people have tried other alternatives, and that they’re prescribed as low dose and short a time period as possible”-Tara Gomes @theglobeandmail.com www.theglobeandmail.com/canada/artic...

The use of prescription #opioids to treat acute pain has decreased in Canada in recent years. But there’s still a need for national information on prescription opioid use specific to different populations. Read the study led by St. Michael’s researchers here: unityhealth.to/2025/10/opio... @cmaj.ca
