'O.C's Barton 'on destructive path'

Mischa Barton has been on a "destructive path" of drug use, it has been claimed.

The 'O.C.' star - who was sectioned on Wednesday after being placed under a 5150 hold, a piece of US legislation which means she poses a danger to herself or others - has allegedly been drinking heavily and experimenting with drugs, much to the concern of her friends.
