Marijuana Use Sparks Liver Transplant Controversy

Hepatitis C is not only the leading cause of chronic liver disease in the United States, it is also the most common reason for liver transplants in this country. Unfortunately, some with Hepatitis C are being denied access to liver transplants because of their use of a controversial type of symptom relief.
Although transplantation is considered a last resort for liver disease, the number of people waiting for a new organ far outnumbers the supply. Since donated livers are in such high demand, a complex system of prioritizing who gets transplant surgery has evolved. Obviously, great deliberation is involved in deciphering transplant eligibility and recipient ranking. However, the ethics of this process has been called into question for those using medical marijuana. Occasionally used to ease Hepatitis C symptoms, patients legally using medical marijuana are at high risk of being denied a spot on the liver transplant recipient queue.
UNOS
The United Network for Organ Sharing (UNOS) is a non-profit, scientific and educational organization that administers the nation’s only Organ Procurement and Transplantation Network. UNOS is responsible for organ matching and placement throughout the United States. According to the UNOS website, over 98,000 people are currently on an organ transplant waiting list. Many people wait for years for a new liver, often not surviving the wait. According to the Scientific Registry of Transplant Recipients, less than a third of those waiting for a liver actually receive one.
The UNOS entrusts individual hospitals and transplant centers to develop their own criteria for transplant candidates. Some of these institutions automatically reject people who use “illicit substances” — including those legally prescribed medical marijuana. “Most transplant centers struggle with issues of how to deal with people who are known to use marijuana, whether or not it’s with a doctor’s prescription,” said Dr. Robert Sade, director of the Institute of Human Values in Health Care at the Medical University of South Carolina. “Marijuana, unlike alcohol, has no direct effect on the liver. It is, however, a concern … in that it’s a potential indicator of an addictive personality.”
Medical Marijuana
Marijuana has been used for medicinal purposes for approximately 4,000 years. Surviving texts from ancient India confirm that its psychoactive properties were recognized, and doctors used it for a variety of illnesses and ailments. These included a whole host of gastrointestinal disorders, nausea, low appetite, insomnia, headaches and as a pain reliever.
People with Hepatitis C have reported using marijuana (cannabis) to treat both symptoms of the disease as well as the nausea associated with antiviral therapy. An observational study by investigators at the University of California at San Francisco (UCSF) found that Hepatitis C patients who used cannabis were significantly more likely to adhere to their treatment regimen than patients who didn’t use it. Despite this support for medical marijuana, several trials reported an association between daily cannabis use and the development of liver fibrosis in Hepatitis C. Aside from the question of legality, experts disagree on the therapeutic use of cannabinoids for Hepatitis C treatment.
The medical use of cannabis has been legalized in several countries including Canada, Belgium, Australia, the Netherlands, the United Kingdom, New Zealand and Spain. Since 1996, twelve U.S. states have legalized medical marijuana use: Alaska, California, Colorado, Hawaii, Maine, Montana, Nevada, New Mexico, Oregon, Rhode Island, Vermont and Washington. Doctors in these states can write a prescription for marijuana for a legitimate medical issue. However, the United States Supreme Court ruled that the federal government has the right to regulate and criminalize marijuana in these states, even for medical purposes.
Sad Outcome in Washington
The debate about medical marijuana’s impact on liver transplant eligibility jumped to center stage in May of 2008 when Washington state resident Timothy Garon passed away. To combat his Hepatitis C symptoms, Garon’s physician had authorized medical marijuana for alleviating his nausea and stomach pain and to stimulate his appetite. Legally authorized in Washington state since 1998, Garon’s attorney believes that his client’s medical marijuana use kept him off of the liver transplant list, a decision that ultimately cost Garon a chance for survival.
No one tracks how many patients are denied transplants over medical marijuana use. Pro-marijuana groups have cited a handful of cases, including at least two patient deaths, in Oregon and California, since the mid- to late 1990s, when states began adopting medical marijuana laws.
With the nation’s shortage of transplantable livers, some administrators may be using their moral judgment to decide who gets on an eligibility list. Thus, using medical marijuana to ease advanced Hepatitis C symptoms may put some people at a disadvantage. Until our nation’s lawmakers, physicians and administrators are all in agreement about the use of cannabis for certain illnesses, those in need of a liver transplant may wish to think ahead – and either choose a different medicine for symptom relief or consult with their chosen hospital about their view on medical marijuana as a factor in transplant eligibility.
