An article in the Science Daily questions whether decisions that refuse liver transplants to marijuana patients are justifiable since there is no non-empirical evidence that shows a relationship between the likelihood of rejection and marijuana use.

The Science Daily Press Release indicates that Canadian transplant centers are more willing than those in the United States. The author Karen Kroeker from the University of Alberta says that to deny patients who are in pain and whose only option of relieving the pain is to smoke cannabis is “unacceptable”, particularly given the lack of evidence to justify a refusal.
