The Impact of Preoperative Cannabis Use on Postoperative Pain and Opioid Use in Orthopaedic Surgery Patients: A Scoping Review

Most evidence suggests that preoperative cannabis use has no effect on opioid use after orthopaedic surgery. Few articles investigated the associations of preoperative cannabis use with postoperative pain, and results were mixed, with only one study evaluating cannabis use in upper extremity surgical patients, suggesting the need for further exploration in some fields. No studies were able to measure duration of cannabis use, method of consumption, or potency because the use was either self-reported or based on a diagnosis of cannabis use disorder, indicating the need for future studies to stratify preoperative cannabis use by methods of ingestion and amount consumed.
