Will her organs be fit to use if she was on cocaine and other drugs?
Depends on if she had internal injuries that damaged her liver, heart, and kidneys. Her lungs were probably burnt from the fire. And they can use tendons, too.
Heche's organs are most likely not suitable for transplant due to prolonged oxygen deprivation. Since her brain did not receive adequate oxygen, her other organs did not either. Her lungs were severely damaged by fire, smoke and other inhaled hazardous materials. Thus, the lungs were not able to successfully exchange and deliver oxygen supply to the rest of the body.
Photos of Ms. Heche being loaded into the ambulance showed soot covering her hair and clothing. Her feet were visibly black and charred.
The paramedics and hospital probably had her on drugs the second she got into the ambulance.
I answered on an earlier thread hypothetical about a person in a car crash and they have them doped up to manage their pain. They still proceed with it harvesting.
Glass cutters are bidding on her nipples right now
