The request came after a former nutritional counselor said Jackson repeatedly asked her for the drug Diprivan in order to sleep.
Almost immediately after Michael Jackson was found unresponsive at his rented Los Angeles home and pronounced dead at the L.A. Medical Center, the investigation into his death turned to his medications and the healthcare that he was receiving.
Addicted to Pain Killers?
The Los Angeles Police Department impounded a vehicle driven by Jackson's live-in doctor, Dr. Conrad Robert Murray, because they thought there could be medications in the car relevant to their investigation.
Jackson's family members told reporters that Dr. Murray administered the painkiller Demerol to Jackson shortly before he died, but Murray's attorney denied that he had ever given Jackson any Demerol or Oxycontin, the drug to which Jackson was allegedly addicted, according to court records.
ABC News reported that a senior law enforcement official close to the initial investigation said Jackson was "highly addicted" to the painkiller Oxycontin and took daily dosages of it.
Jackson Begged for Propofol to Sleep
Later, Cherilyn Lee, a registered nurse who provided nutritional counseling to Jackson and his children, told The Associated Press that Jackson suffered from chronic insomnia and had recently begged her to administer the powerful sedative diprivan (Propofol) to help him sleep.
Although she repeatedly refused to give him propofol, she said Jackson insisted that "his doctor" said it was safe to use. Although propofol can be abused, the drug is typically used by doctors to relax patients so a breathing tube can be inserted for surgery or to help them tolerate being on the ventilator while in intensive care.
The drug is always administered in a hospital setting so that the patient can be closely monitored with a heart monitor and usually while on a ventilator. Propofol is never administered in a home setting without monitoring devices to assist with sleeping problems.
DEA Asked to Join Investigation
This week, the investigation into the medications Jackson may have been taking intensified when the DEA's diversion division was asked to join the LAPD probe. The division has regulatory authority over prescription drugs.
"We routinely offer assistance to any agency regarding the Federal Controlled Substance act, however at this time we have nothing further to comment about the death of Michael Jackson," the DEA said in a statement.
Meanwhile, the L.A. Coroner's Office is awaiting on the results of toxicology tests before determining the actual cause of Jackson's death. The tests should reveal what drugs were in his system at the time of death.
Experts say that most deaths due to drug overdose are not due to taking too much of one particular drug, but caused by a combination of drugs taken together, such as taking sedatives along with pain medications.
