High doses of cocaine can cause the brain to eat itself, research suggests.But not all is lost, a drug already in use to treat Parkinson's can help prevent the process:
A mouse study found that the drug can trigger out-of-control ''autophagy'' - a process by which cells literally digest themselves.
When it is properly regulated, autophagy provides a valuable clean-up service - getting rid of unwanted debris that is dissolved away by enzymes within cell ''pockets''.
The scientists showed that an experimental drug called CGP3466B was able to protect mouse nerve cells from cocaine death due to autophagy.So will dealer sell CGP34466B with their crack?
Since the drug has already been tested in clinical trials to treat Parkinson's and motor neurone disease, it is known to be safe in humans.
Cocaine may be bad for brains, but it's been good for music:
