This reminds me of the documentary Bigger Stronger Faster. He interviews a bunch of musicians that are using Beta blockers.
It's pretty interesting because they admit that the use is rampant, it is for performance enhancement, they cite wanting to be the best or better than others in order to gain employment, and some of them admit to being on them at that moment or that they will be on them during the coming performance. No where near the same stigma as pro athletes.
In regards to anabolic steroids, there is a actually a lot of talk in the UFC right now because one of the heavyweight fighters failed a pee test with a T/E ratio something like 14:1 (they allow 6:1 I believe). Nothing has been proven or dis-proven as of yet, his official statement so far is anti-inflammatory drugs with testosterone caused it, but speculation is not in short supply.
Personally I understand an athlete's, or anyone's, desire to be the best or to become better and better but I am wholeheartedly against performance enhancing drugs.

"We are not sport, when there is a sport issue, we are not so good. The boxer is much better than us at boxing. But he will have to protect his balls if he wants to punch us."
