Weed is antiinflammatory, as are other plants, and fish as well. Your immune cells do cause the inflammation, and anti-inflammatory effects are caused by suppressing the immune system. It's interesting that people tried to discourage pot smoking by telling people that it suppresses the immune system, but this suppression is actually quite healthy, as it can counteract heart disease and other chronic diseases. An inflammatory state is directly associated with disease. Exercise also reduces inflammation. Some parasites put out antiinflammatory chemicals in order to suppress the immune system so that they can survive in your body, and hence help to prevent chronic disease. This is a true symbiotic relationship. I wonder if making a marijuana drink would be more effective than smoking it though?
