Rest in peace, Timothy Garon. I'm not making it up, this really happened:

SEATTLE (AP) — A man who was denied a liver transplant because he used marijuana with medical approval to ease the symptoms of hepatitis C has died.
…

His death came a week after his doctor told him a University of Washington Medical Center committee had again denied him a spot on the liver transplant list because of his use of marijuana, although it was authorized under Washington state law.

They let him die. They let him die because he took his doctor's advice and used medical marijuana to treat his hepatitis C.

Here's what the Washington Post, a reputable news source, said about marijuana and hepatitis C. This is from 2006, a long enough time ago to make policy changes:

Marijuana can improve the effectiveness of drug therapy for hepatitis C, a potentially deadly viral infection that affects more than 3 million Americans, a study has found. The work adds to a growing literature supporting the notion that in some circumstances pot can offer medical benefits.

So marijuana is effective in treating hepatitis C, unless of course, the fact that you used marijuana is held up as an excuse to deny you a liver transplant, in which case using marijuana will get you killed. If what they did to Timothy Garon doesn't qualify as medical malpractice, then it's time to rewrite the rules.
