President Bush came down pret-ty hard on the use of anabolic steroids in professional sports in the State of the Union Address last night. It was an odd area for him to tackle -- no natural political constitutency I can think of demanding steroids regulation. But since the Prez is known to be a sports fan, maybe banning roids just his idea of, well, a good idea (or maybe he thought that must explain howard Dean's YEEEEEEEEEAAAAAARRRRRRGGHHHHHH!!!!!! after Iowa -- a 'roid rage).

Either way, performance enhancing drugs, while not new to sports, are going to be hard to get rid of. This SciAm story helps explain why:

"... it is fairly easy for organic chemists to design novel anabolic steroids that standard drug tests would not detect. "
