Yup, folks like Freddy are lurking DU dolts that pleasure themselves with mental masturbation of an honest man that has admitted the he has an addiction problem to PRESCRIBED anti-pain medicine.
Saying that Rush' drug of choice is prescription drugs is meaningless. Besides the use of other-than-mainstream channels, shall we say, it doesn't sound like he was following doctor's orders, does it,? He's fortunate that it came out the way it did - he's apparently had serious intent-to-distribute weight on him, 10-15 year weight, so much that FL's deferred adjudication avenue probably wouldn't be open for him.
I wish him well, the detox won't be easy, as he knows.
Don't quit your day job, cobra, your Karnac impression sux. ;>/
