There are many anecdotal reports about improvement of Inflammatory bowel diseases (IBD) with
cannabis smoking. The most effective anti inflammatory compound known today is cannabidiol.
cannabidiol can be extracted from the cannabis plant, it has no central effect and is fat
soluble so it can be given as drops in oil. Doses of up to 500mg did not cause any side
effects.
The aim of the proposed study is to examine in a double blind placebo controlled fashion the
effect of cannabidiol on disease activity in patients with IBD.
