To the Editor We read with great interest the article by Stewart and Fong regarding perioperative cannabis use.1 The authors provided an informative overview of cannabis use and many of the pertinent issues surrounding it. However, we strongly disagree with their recommendation that cannabis products be stopped 10 days prior to a surgical procedure. While succinct guidance is easy to adopt into clinical pathways, this gross oversimplification of a nuanced clinical issue is potentially harmful to patients.
