Cocaine: 'brain eats itself'

Dr. Prasun Guha of Johns Hopkins School Of Medicine published a mouse study of a crack-fueled "autophagy'' of grey matter. 

''Autophagy is the housekeeper that [normally] takes out the trash...But cocaine makes the housekeeper throw away really important things, like mitochondria, which produce energy for the cell.''

In short cocaine causes the brain to cannibalize itself.  Gives big hints what happened to Whitney Houston, John Belushi, River Phoenix, and Chris Farley.

And could explain Obama and Bill Clinton wandering around in the bizarro world too...
