Meanwhile, new research by lead study author Elyad Ekrami, MD, a clinical research fellow at the Outcomes Research Department at the Cleveland Clinic’s Anesthesiology Institute, found that cannabis users tend to experience more pain after surgery, resulting in a higher opioid intake. They analyzed the medical records of 34,521 adult patients, 1,681 of whom were cannabis consumers. These patients had elective surgeries done at the Cleveland Clinic from January 2010 through December 2020.
