Before everyone argues this, you might want to consider that, as far as I'm aware, there has been no official determination of cause of death. That means no legal determination that this man was an abuser of drugs (prescription or otherwise), no determination it was a suicide, no determination it was an accidental overdose or even a drug reaction. Until the ME says so, it's all purely speculation.

The stuff that goes on online when a famous person dies, simply astounds me.
