While the news of the positive drug test results is not good, at least it shows that there is a viable system in place and this system appears to be working. Now that MMA is beginning to generate more money and garner more mainstream attention, there will be those athletes looking for whatever edge they can muster. As we've seen in other sports, this is inevitable. The only thing the sports leagues and sanctioning bodies can do is have a system in place to catch the cheaters. It appears MMA and UFC have just such a system in place.
