“Researchers at the University of South Carolina conducted a study that analyzed the effects of THC in marijuana on patients with autoimmune diseases because the drug has previously shown to have an immunomodulatory activity.
Immunomodulatory means something is capable of modifying or regulating one or more immune functions, or can provide an immunologic adjustment, regulation, or potentiation. In this study’s case, the researchers found that the application of marijuana has the ability to suppress an immune response to treat autoimmune diseases, such as arthritis, lupus, colitis, multiple sclerosis, and others.”
