I can assure you, if Rush took 10 oxy's in one day, much less 30, he'd be dead. Very powerful medicine.
One other thing, people addicted to pain medication and who have taken large doses over a long period of time, like crack heads and speed freaks, are quite obvious in their intoxication.
I'm not a Rush listener nor fan, but this whole pill scandal stinks to high heaven. A man with Rush's money and stature would have no problem obtaining legal scripts, especially if he is friends with any sports related doctors, who aren't placed under the same scrutiny as regular doctors. Not mentioning the fact that oxycontin is more expensive to buy on the street than legally.
Even if Rush was buying pills illegally, again, people with his money don't buy from maids. Rush is smart enough to know that the media would pay a large sum to bring him down for any reason, and someone who doesn't make much money, like a maid, wouldn't hesitate to take that money and throw Rush under the bus.
Think about this too. Rush is hated by the klintoon camp, masters at dirty politics and smear tatics. I'd be willing to bet that Rush has been under the microscope for several years now, by paid pros who are very good at what they do, with nothing to show for it.
