Background:
Crohn’s disease is an idiopathic inflammatory process that is occasionally associated with complications, which cause significant morbidity and mortality. The anti-inflammatory effect of cannabis in intestinal inflammation has been shown in several experimental models; it is unknown whether this correlates with fewer complications in Crohn’s disease patients.

Aims: To compare the prevalence of Crohn’s disease-related complications among cannabis users and non-users in patients admitted with a primary diagnosis of Crohn’s disease or a primary diagnosis of Crohn’s related complication and a secondary diagnosis of Crohn’s disease between 2012 and 2014.

Methods: We used data from the Healthcare Cost and Utilization Project–National Inpatient Sample. Cannabis users (615) were compared directly after propensity score match to non-users, in aspects of various complications and clinical end-points.

Results: Among matched cohorts, Cannabis users were less likely to have the following: active fistulizing disease and intra-abdominal abscess (11.5% vs. 15.9%; aOR 0.68 [0.49 to 0.94], p = 0.025), blood product transfusion (5.0% vs. 8.0%; aOR 0.48 [0.30 to 0.79], p = 0.037), colectomy (3.7% vs. 7.5%; aOR 0.48 [0.29–0.80], p = 0.004), and parenteral nutrition requirement (3.4% vs. 6.7%, aOR 0.39 [0.23 to 0.68], p = 0.009).

Conclusion: Cannabis use may mitigate several of the well-described complications of Crohn’s disease among hospital inpatients. These effects could possibly be through the effect of cannabis in the endocannabinoid system.
