Mischa Barton says someone put GHB in her drink and caused her to act erratically.

Actress Mischa Barton, who has recently been hospitalized at her own will after the police were called to her home, reveals that her disturbing behaviour that day was due to the fact that the previous night she had been drugged with GHB.

Mischa Barton appeared mentally disturbed on a video released by TMZ last week. She was wearing a long shirt and her hair in a messy tail and was rambling, in her backyard, hanging over the fence. This was happening on Thursday morning, the day after the actress celebrated her 31st birthday.

She went willingly to Cedars-Sinai Medical Center for a mental evaluation. After her release, the O.C. star talked to People about the incident. She said that the night before she had gone celebrating her birthday with a group of friends. They were having drinks and having a good time when she says she started feeling…not herself: “I realized that something was not right as my behavior was becoming erratic”. She continued by saying it became more obvious with each hour that passed that she was not behaving normally.

The next day, at the hospital, she found out that she had been drugged with GHB, a drug that is usually poured in drinks and acts like a depressant. It is also known as the “date rape drug”. “This is a lesson to all young women out there, be aware of your surroundings”, said Barton.

There is no report that Barton had been abused physically as a result of ingesting the drug.

The police that showed up at her West Hollywood residence confirm that the actress was “fully clothed” and “speaking coherent statements”. She was in the house with another person at the time – a houseguest.

Barton’s erratic behaviour was caught on tape and released by TMZ.
