About one in six IBD patients who use marijuana say it helps with their symptoms, so researchers decided to put it to the test. Thirteen patients with IBD were given a third of a pound of marijuana to smoke at their leisure over a period of three months, and they reported feeling significantly better with “reported improvement in general health perception, social functioning, ability to work, physical pain, and depression.” There wasn’t a control group, so it’s unknown if they would have improved anyway or what role the placebo effect may have played. It’s like some of the studies of cannabis used for pediatric epilepsy that had response rates exceeding 30 percent and a frequency cut in half in a third of the kids. Amazing results until you realize you can sometimes get similarly amazing responses from giving kids nothing but a sugar pill placebo, as seen below and at 2:21 in my video Friday Favorites: Cannabis for Inflammatory Bowel Disease (IBD). That’s why it’s critical to do randomized, double-blind, placebo-controlled trials, but there weren’t any on cannabis and IBD until 2013.
