Michael Jackson's Drug Abuse: Portrait Of His Pill Consumption Emerges

A picture is emerging of Michael Jackson's copious consumption of prescription pills that is downright disturbing. CNN obtained a confidential document that portrays the pop singer as heavily addicted to the powerful anti-anxiety drug Xanax, which Jackson used to battle insomnia.

Jackson was routinely taking more than 10 Xanax pills a night, and was going to extreme lengths to keep up his vast supply, using multiple employees to fill prescriptions of the drug for him under their own names.

According to the document CNN obtained, one Jackson staffer offered this shocking statement: "Jackson was doing better because he was down from 30 to 40 Xanax pills a night."

Additionally, TMZ reports that they've confirmed via law enforcement sources that "Jackson had "dozens" of injection sites and punctures all over his body the day he died."
