I don't know if I could have withstood the pain Rush underwent, nor its resulting consequences.
Your comment implies that Limbaugh's pain was the only factor driving him to use the drug, and that the best medical care money could but was negligent in alleviating or was unable to alleviate it. And so he had to bravely and forlornly break away from accepted clinical practice and medicate himself.
Nonsense.
Limbaugh was into the drug for the high. That's what addicts do, and that's why they concoct schemes to procure drugs in whatever way possible, just as Limbaugh did. Sorry to burst your bubble.
