Even if baseball and the players union agreed to every recommendation in the Mitchell Report tomorrow, stemming the use of performance-enhancing drugs will be a long-term project with no easy solutions. Experts devoted to eliminating drugs in sports say it's a three-part problem, one that involves finding an effective test for human growth hormone, staying ahead of those creating new illegal drugs and, most importantly, changing the drug culture in baseball. Don Catlin, one of the world's foremost scientists in the fight against doping, said he has made some headway with the $500,000 that Major League Baseball gave him to begin work on finding an effective urine test to detect human growth hormone. HGH was identified in the Mitchell Report as one of the biggest problems, in large part because it's nearly undetectable. Only blood tests currently can detect signs of HGH use, and they aren't considered advanced enough to catch cheaters who use any measure of sophistication. A urine test is thought by some to be years away, though Catlin is trying, and has had enough success that he is considering asking for more money to move the studies forward. "But let's say we get that contained tomorrow," Catlin said. "The next day, there's going to be another one."
