Hi, Thanks for writing in to us. Hepatitis is of many types, commonest being A, B and C. Type A hepatitis is a self limited acute infection and total recovery occurs in most patients. Type B hepatitis is an acute and/ or chronic infection and can persist in blood for many years to cause chronic liver disease. Type C hepatitis is also a chronic disease and may cause severe liver disease after a long time. Research has been done on cannabis in liver disorders: Frequent use of cannabis has been shown to contribute to liver damage. As well as this, research has shown that the use of cannabis may suppress immune function and enhance the development of disease. With this in mind, avoiding frequent use of cannabis is advised. People who have hepatitis C and use cannabis everyday are more likely to have severe fibrosis which can then lead to cirrhosis of the liver. If you have been diagnosed with hepatitis C, you may have heard that occasional or light use of cannabis has been shown to help some people deal with treatments and side-effects. However, if you are considering using cannabis during treatment you should also be aware that it may do more harm than good and discuss it with your specialist. Hope this helps
