On her doctor's advice, [Raich] eats or smokes marijuana every couple of hours to ease her pain and bolster a nonexistent appetite.
"It's not something I want to do. It's something I have to do to survive," Raich said.
The Supreme Court ruled against Raich two years ago, saying that medical marijuana users and their suppliers could be prosecuted for breaching federal drug laws even if they lived in a state such as California where medical pot is legal.
Because of that ruling, the issue before the 9th U.S. Circuit Court of Appeals was narrowed to the so-called right to life theory: that marijuana should be allowed if it is the only viable option to keep a patient alive.
Raich , 41, began sobbing when she was told of the decision and said she would continue using the drug.
"I'm sure not going to let them kill me," she said. "Oh my God."
