“Cannabidiol (CBD) is an anti-inflammatory cannabinoid shown to be beneficial in a mouse model of IBD. Lacking any central effect, cannabidiol is an attractive option for treating inflammatory diseases. In this study of moderately active Crohn’s disease, CBD was safe but had no beneficial effects. This could be due to lack of effect of CBD on Crohn’s disease, but could also be due to the small dose of CBD, the small number of patients in the study, or the lack of the necessary synergism with other cannabinoids.”  https://www.ncbi.nlm.nih.gov/pubmed/28349233

“Cannabis induces a clinical response in patients with Crohn’s disease: a prospective placebo-controlled study. We performed a prospective trial to determine whether cannabis can induce remission in patients with Crohn’s disease. Complete remission was achieved by 5 of 11 subjects in the cannabis group and 1 of 10 in the placebo group. A short course (8 weeks) of THC-rich cannabis produced significant clinical, steroid-free benefits to 10 of 11 patients with active Crohn’s disease, compared with placebo, without side effects.”  https://www.ncbi.nlm.nih.gov/pubmed/23648372
