Mischa Barton leaving the BAFTA awards in London (4/26)

Mischa Barton was removed from her LA home yesterday by police. Details are sketchy but it's believed that Mischa called the police herself after having a "freak out" -- whatever the hell that means. From Us Weekly:

"We responded to her home last night on a medical issue," Officer April Harding tells Us. "We assisted with it. She was removed from her home."

Harding tells Us no 911 call was received, and that she was not sure if Barton, 23, was in distress. When asked if the actress was cooperative, she tells Us: "I guess."

Harding did not release details on where Barton was taken, citing California privacy laws.

In completely unrelated news so don't draw any conclusions from this whatsoever, drugfree.org says this about the short-term effects of LSD:

The user may feel several different emotions

Like a feeling of failure that comes from, say, your career hitting such a dead end that you can't even get the lead in a "movie of the week" on Lifetime?

at once or swing rapidly from one emotion to another. If taken in a large enough dose, the drug produces delusions and visual hallucinations.

Like you'd look in a mirror and imagine that you didn't weigh 175 pounds?

The user's sense of time and self changes.Sensations may seem to "cross over," giving the user the feeling of hearing colors and seeing sounds.These changes can be frightening and can cause panic.

Such panic that you'd freak out and call polic -- wait, what were we talking about again? Oh yeah, Mischa Barton. Uh, get well soon.
