There are plenty of anecdotal reports regarding bile duct Cancer being cured by Cannabis, however, these are not scientific studies. Although there are no studies about Cannabis curing bile duct Cancer, there are studies on Cannabis and Cancer in general. As per the American Cancer Society, "a number of small studies of marijuana found that it can be helpful in treating nausea and vomiting from cancer chemotherapy and neuropathic pain. More recently, scientists reported that THC and other cannabinoids such as CBD slow growth and/or cause death in certain types of cancer cells growing in lab dishes. Some animal studies also suggest certain cannabinoids may slow growth and reduce spread of some forms of cancer. There have been some early clinical trials of cannabinoids in treating cancer in humans and more studies are planned. While the studies so far have shown that cannabinoids can be safe in treating cancer, they do not show that they help control or cure the disease".
