Over the course of the last two years, the PGA Tour has been formulating a policy to begin testing players for performance enhancing drugs [see "Tour Readies Policy" in sidebar].
Observers may question the concept, wondering what steroids could possibly do to give a player a leg-up in a sport where eye-hand coordination is everything and brute force means little. As a matter of fact, the case can be made that the side effects of performance enhancing drugs would be detrimental to success on tour. To play well, a person's personality must be very evenly-keeled, not getting too excited about a birdie and not getting too depressed about a bogey, and if you've witnessed the mood swings of Barry Bonds -- remember that rambling, depressed, and paranoid interview he gave while out with an injury a few years ago? -- you know that those side effects are real. An example can even be found on right tour in John Daly. While Daly certainly isn't taking steroids or HGH, his performance is often hampered by mood swings brought on by other chemical distillations.
In the end, the PGA Tour's testing policy would be all about perception and a little bit about prevention. Golf has always had a squeaky clean reputation and deservedly so. The players aren't involved in dog fighting or "stroke-shaving" and except for Gary Player, no one seriously thinks anyone is juicing. And that's the point, Tim Finchem, the tour's commissioner, wants to keep it that way. He doesn't want to be the next Bud Selig, viewed as the executive that fiddled while Rome burned.
Decades ago, it was considered foolish for baseball players to lift weights, it was thought that the added bulk would only limit flexibility and prevent 
athletic movement. We've seen that was not the case and the bulked-up batter has done more to change the face of baseball than anything since the Dead Ball Era. Similarly, golf was thought to be a sport where muscles were not helpful, but have you seen Tiger Woods lately? Dude's ripped. While power isn't everything on tour, there's no doubt it's becoming more important. The idea to test players is nothing more than heading a problem off at the pass.
Make no mistake, there's no drug-problem on the PGA Tour, they're just keeping it that way.
Heck, if anything is juiced, it's the ball.
