Agreed with what mrbear666 said. Drugs in sport are here to stay, and sadly, if a professional athlete who is world-class in any sport that requires maximal speed, strength or a combination thereof says they're drug-free, it's 99.9% likely that they're lying to you.
It's a shame when things happen like the baseball witch-hunts that single out only a few players when the majority are using, just as it's terrible that Lance Armstrong was singled out when, as it's commonly said, if you make it to compete in the Tour de France, it's assumed that you're already taking a lot of drugs just to have gotten that far. Someone like Armstrong would have been the best regardless of whether everyone was drugged or everyone was clean, but since he was at the top, all the others could do was try to destroy him out of jealousy while trying to keep their own actions hidden. I'm keeping my fingers crossed that, for all he's gone through, the rest of the non-clean people who worked to take him down go down with him. What's fair for one is fair for all, and just because he was the naturally better athlete shouldn't have made him the focus while leaving the heat off everyone else who competes and isn't clean.
Unless they can clean up sports entirely (which they can't), I don't see why there's any fuss over pretending that some people should be targeted for their choices while the vast majority slip through without notice because they're not at the top of the game. I don't plan on using anything in this lifetime, but of course, if playing my sport professionally were my livelihood and millions of dollars were on the line, I can't say that I wouldn't fall prey to temptation. If there were a company waiting on the sidelines with a multi-million dollar check for my endorsement of their sports products, I'm sure there'd be a LOT of struggle over how to make sure I'd stay at the top when knowing that drugs were pretty much the norm and that I wouldn't be doing anything different from what the rest of the competitors were doing. It's always easy for people to say "I'd NEVER use anything that artificially enhances my performance!", but I can only assume that the people who say that have never had a large amount of money on the line if they were to go that direction and make it to the top
