Pal: Demi Passed Out From Inhaling Nitrous Oxide

The seizure that landed Demi Moore in a hospital this week was apparently triggered by "whip-its." TMZ talked to sources who say that the actress was inhaling nitrous oxide for a cheap, quickie high; a friend at Moore's home became concerned and called 911. The 49-year-old actress was “shaking” and otherwise “acting like she was suffering from a seizure,” a source told E! News. The gas is usually obtained from whipped cream cannisters and provides a sudden, intense high.

Moore has a recent history of substance abuse, according to People. A battle with prescription drugs is one reason her marriage to Ashton Kutcher fell apart, sources told the magazine. “He wanted her to take care of herself and get a hold of things, and she wouldn’t," said a pal. Her family and friends have been really worried." Said another source: "Demi is a mess." (More Demi Moore stories.)
