Increasing numbers of patients are using cannabis before procedures that require anesthesia. This study set out to examine the impact of cannabis use on anesthetic agent requirements, associated cardiac and respiratory morbidity, and overall satisfaction levels in patients undergoing esophagogastroduodenoscopy (EGD). This involved a retrospective review of patients undergoing EGD at a single center. Fortyseven, self-reported cannabis users were identified and 23 were successfully cross-matched with control participants for comparison purposes. The Wilcoxon signed rank test was used to evaluate differences in propofol administration between the 2 groups, and the McNemar test was used to test for differences in fentanyl and ketamine administration. No statistically significant differences were observed in propofol, fentanyl, or ketamine administration in the cannabis group compared with the control group. No adverse cardiac or respiratory events were reported within 30 days for either group. This study was specific to EGD procedures of short duration, and larger studies are needed to confirm results of no consequence in cannabis users undergoing anesthesia. Future studies should consider cannabis users who undergo anesthesia for diverse procedure types of various durations.
