JacksonIntervention.jpgWith reports surfacing that an overdose of the prescription drug Demerol may have led to the sudden death of Michael Jackson, People magazine is reporting his family once tried to have an intervention in Las Vegas.

According to the magazine, back in 2006 Jackson family members gathered in the hopes the pop star would seek treatment for his reported dependence on prescription painkillers.

"The family believes Michael was addicted," People reports. "There was an intervention in Las Vegas. Janet was on the phone, but Randy, Jackie and Rebbie were there in person," a source said.

Michael reportedly became angry at the family's accusations, saying "he wasn't on drugs."

At the time of the intervention, the family feared a Jackson confidant was providing him powerful prescription drugs obtained from several doctors.

Jackson allegedly regularly consumed alcohol and took morphine, Demerol and opiates like Oxycontin, as well as anxiety drugs like Valium and Xanax.

After Jackson's death, family attorney Brian Oxman said he believed drugs will prove to be a factor.

"If you think that the case of Anna Nicole Smith was an abuse, it's nothing in comparison to what we have seen in Michael Jackson's life," Oxman told CNN.
