Cannabis has been shown to be an effective treatment for psoriasis in a number of studies. The active compounds in cannabis, including THC and CBD, have anti-inflammatory and immunosuppressive properties, which makes them ideal for treating the symptoms of psoriasis. In one study, CBD was found to be more effective than a placebo in reducing the symptoms of psoriasis. Cannabis is also effective in treating the underlying causes of psoriasis, such as inflammation and immune system dysfunction. In a study of rats with psoriasis, CBD was found to reduce inflammation and improve the function of the immune system. There is also some evidence that cannabis can help to reduce the proliferation of skin cells, which is a major factor in the development of psoriasis.
