“In ancient medicine, cannabis has been widely used to cure disturbances and inflammation of the bowel. A recent clinical study now shows that the medicinal plant Cannabis sativa has lived up to expectations and proved to be highly efficient in cases of inflammatory bowel diseases.
In a prospective placebo-controlled study, it has been shown what has been largely anticipated from anecdotal reports, i.e. that cannabis produces significant clinical benefits in patients with Crohn’s disease. The mechanisms involved are not yet clear but most likely include peripheral actions on cannabinoid receptors 1 and 2, and may also include central actions.”

“In their prospective study, Naftali et al. used THC-free Cannabis as placebo with no other cannabinoids present. However, we should consider that also other ingredients of Cannabis, such as cannabidiol, cannabigerol, and tetrahydrocannabivarine (THCV), all of them non-psychotropic components of Cannabis, have proven antiinflammatory effects in experimental intestinal inflammation. Their actions partly involve non-CB receptor mechanisms via, for instance, peroxisome proliferator-activated receptors (PPAR) and transient receptor potential cation channels subfamily V receptors (TRPV) and should be regarded as additive beneficial effects of Cannabis in the improvement of colitis in addition to THC-mediated effects.
…an 8-week treatment with THC-rich Cannabis caused a decrease of the Crohn’s disease activity index (CDAI) in 90% of patients without producing significant side effects…
In summary, in agreement with the ancient use of Cannabis in intestinal disturbances and one decade of animal research, Cannabis was shown in a clinical trial to reduce symptoms in patients with CD. This elegant translation should be followed by larger trials confirming these results and by trials establishing the involved mechanisms to open a promising direction for future treatment of IBD.”
