"Researchers at Israel’s Meir Medical Center took 21 people with intractable, severe Crohn’s disease and gave 11 of them two joints a day for eight weeks. The other ten subjects smoked placebo cigarettes containing no active cannabinoids.
Investigators reported that smoking weed caused a “complete remission” of Crohn’s Disease in five of the 11 subjects. Another five of the eleven test subjects saw their Crohn’s Disease symptoms cut in half. Furthermore, “subjects receiving cannabis reported improved appetite and sleep, with no significant side effects.”
As someone with Crohn’s disease these tests make me very happy, but of course more work needs to be done!
