On one of the calls, played during a press conference Wednesday, a man is heard telling a 911 dispatcher that Odom had used cocaine on Saturday, but had not taken any since then. The man also said Odom had used a natural sexual enhancement supplements.
“He’s taken a bunch of these,” the man said.
Nye County Sheriff Sharon Wehrly said authorities had received a search warrant to test Odom’s blood for drugs. Officers went to Sunrise Hospital in Las Vegas to take the blood early Wednesday morning, and are awaiting results for the toxicology test.
The sheriff would not comment on the possibility that Odom had overdosed on drugs, saying law enforcement officials would not know more until the test results came back.
“We would like to extend our best wishes to Mr. Odom and his family and we re hoping for a speedy recovery,” she said.
A source close to the family previously told PEOPLE that Odom’s estranged wife Khloé Kardashian, Kris Jenner and Kim Kardashian West – who all "dropped everything" and flew to the hospital Tuesday night – have been told by doctors that “cocaine and opiates” were found in Odom’s system.
Kardashian arranged for Odom’s two children from a previous relationship to fly out from New York to be by their father’s side.
A source close to the family tells PEOPLE “premature” and that its still “a waiting game.” “They’re pretty sure this is goodbye, but they’re praying for a miracle,” a source close to the family told PEOPLE Wednesday. “They know that God has the power to heal him, but that’s really the last hope at this point. This is really bad.”
