Total morphine equivalent dose was calculated for both in-house opioid consumption and postoperative prescription opioid usage. Age, ASA, BMI, depression, tobacco use, estimated blood loss, OR time, LOS, disposition to rehab, 30-day readmission, in-house opioid consumption and postoperative prescription opioid usage were compared between groups using t-tests.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Results<\/jats:title>\n                    <jats:p>Of the 220 opioid na\u00efve patients, 29 (13%) patients were identified as cannabis users while 191 (87%) were non-cannabis users. There were no significant associations between opioid na\u00efve cannabis usage and ASA, BMI, tobacco use, EBL, OR time, LOS, disposition to rehab, or readmission. Opioid na\u00efve cannabis users had greater association with depression (31.3% vs 13.7%, P=.017) and younger age (56.37 years vs 65.37 years, P&lt;.001). Interestingly, cannabis use was associated with a lower Charlson Comorbidity Index (CCI), with 1.38 vs 2.49 (P=.002). Cannabis users were found to have increased postoperative prescription opioid usage (2545.41 POST-MED vs 1379.72 POST-MED, P=.019).<\/jats:p>\n                  <\/jats:sec>\n
