Mischa Barton hættuleg sjáfri sér!

Mischa Barton has been on a “destructive path” of drug use in recent months, sources close to the hospitalized starlet told PEOPLE Saturday.

The 23-year-old actress is currently under psychiatric evaluation at Los Angeles’ Cedars-Sinai Medical Center.

On Wednesday, the former O.C. star was placed under a 5150 hold by Los Angeles Police detectives. Under the statue, someone who is gravely disabled or has a mental disorder can be held for up to 72 hours, however, doctors can request an additional 14-day hold if they believe a patient is not fit to be released.

Mischa’s friends accuse the star of drinking heavily and experimenting with drugs — to the concern of the people who love her.

A source told PEOPLE Magazine: “She has been on a destructive path for a while now. Her drug and alcohol use has gotten to a point where it drove people away. I don’t think she knows her limits.”
