Having lots of prescription drugs doesn't mean he was using them.
MJ, like any other person in a home, keeps medicine, such as for stomach, headache, flu etc.
Given his condition, he definitely had a larger collection than most. And given that he has personal physician, they would stock a range of medication so as to have an easy selection to choose from without rushing to the pharmacy each time.
But when reports are made that a huge stash of drugs were taken, the media is willing to depict this as drug addiction, along with some like Deepak and Brian Oxman who love the limelight of the cameras.
As Tmez once put it, beware of the lure of the cameras. Deepak and Oxman were not in touch with Michael, yet they feel they are obliged to discuss his medical condition.
His doctor may have made a mistake but it is highly unlikely that Michael was consuming huge stashes of a variety of medication
But to some it sounds good because they want to draw parallels with Elvis death of drug overdose to depict Michael as broken and sad, yet we all know he was upbeat and happy before passing away.
