LOS ANGELES -- Demi Moore smoked something before she was rushed to a hospital Monday night and was convulsing and "semi-conscious, barely," according to a caller on a frantic 911 recording released Friday by Los Angeles fire officials.
The woman tells emergency operators that Moore, 49, had been "having issues lately."
"Is she breathing normal?" the operator asks.
"No, not so normal. More kind of shaking, convulsing, burning up," the friend says as she hurries to Moore's side.
The recording captures the 10 minutes it took paramedics to arrive as friends gather around the collapsed star and try to comfort her as she trembles and shakes.
Another woman is next to Moore as the dispatcher asks if she is responsive.
"Demi, can you hear me?" she asks. "Yes, she's squeezing hands. ... She can't speak."
When the operator asks what Moore ingested or smoked, the friend replies, but the answer was redacted.
"Some form of ... and then she smoked something. I didn't really see. She's been having some issues lately with some other stuff. So I don't know what she's been taking or not," the friend says.
The city attorney's office advised the fire department to redact details about medical conditions and substances to comply with federal medical privacy rules.
Asked if Moore took the substance intentionally or not, the woman says Moore ingested it on purpose but the reaction was accidental.
"Whatever she took, make sure you have it out for the paramedics," the operator says.
The operator asks the friend if this has happened before.
"I don't know," she says. "There's been some stuff recently that we're all just finding out."
Moore's publicist, Carrie Gordon, said previously that the actress sought professional help to treat exhaustion and improve her health. She would not comment further on the emergency call or provide details about the nature or location of Moore's treatment.
The past few months have been rocky for Moore.
She released a statement in November announcing that she had decided to end her marriage to actor Ashton Kutcher, 33, following news of alleged infidelity. The two were known to publicly share their affection for one another via Twitter.
Moore still has a Twitter account under the name mrskutcher but has not posted any messages since Jan. 7.
During the call, the woman caller says the group of friends had turned Moore's head to the side and were holding her down. The dispatcher tells her not to hold her down but to wipe her mouth and nose and watch her closely until paramedics arrive.
"Make sure that we keep an airway open," the dispatcher says. "Even if she passes out completely, that's OK. Stay right with her."
The phone is passed around by four people, including a woman who gives directions and another who gives details about what Moore smoked or ingested. Finally, the phone is given to a man named James, so one of the women can hold Moore's head.
By the end of the call, Moore had improved. "She seems to have calmed down now. She's speaking," the male caller told the operator.
