Another major competitive advantage for fighters can be gained by using sleep inertia drugs such as amphetamines. The thing amphetamines would do for a fighter is stimulate their nervous system which, in turn, erases thoughts of fatigue, increases their heart rate, and rapidly raises their energy levels.
Drugs like Ritalin, Benzedrine, and Dextroamphetamine are common amphetamines and would be a huge advantage to any UFC fighter. This is tested for in MMA but it usually leaves your system in less than three days. And again, you don’t hear about major news outlets reporting fighters getting busted for using these drugs.
So what’s the bias against steroids? In my opinion, it stems from the fact that so many other pro sports organizations have demonized them that it wasn’t long before the sport of mixed martial arts followed suit. And since steroids are illegal in the United States and UFC events take place here, it’s only obvious that they cave into the pressures of the state.
On top of this, the media is to blame as well since reporting about a major athlete testing positive for steroids always seems to draw a top headline. On the other hand, Amphetamines and EPO usage among athletes just isn’t a hot enough bandwagon topic to jump on for the media.
And if you disagree with all of this, just look at the differences in how the steroids issue is handled in the US and its major MMA organization, the UFC, versus Japan and its formerly popular PRIDE Fighting Championships.
In the US steroids are banned from pro sports, the media chastises roids and juicers, and it’s argued that MMA fighters gain competitive advantages using them. Contrast that with Japan where steroids are not tested for in sports, the media does not think that roids will prove to be the undoing of the world, and many Japanese people don’t argue that juicers have a huge upper hand in MMA.
The former president and CEO of PRIDE, Nobuyuki Sakakibara, shined some light on this by saying, “We don't test for steroids or we don't have a third party to test for steroids. But we don't think that always the steroid user has an advantage over a fighter who's not using steroids. And we don't know who is using steroids and who is not using steroids. But we don't know if always the steroid users are winning over the non-steroid users.”
Regarding the situation in Japan with steroid testing in sports, he added, “We are not opposing American regulations and requirements of steroid testing. But in Japan there's no such thing. We are not required to test steroids for any fighter or any sports whatsoever. So we don't need, so we don't do. If we come to the U.S. and of course we have to follow their rules and regulations. If we have to do, we have to do.”
This just shows the differences in culture at work. Steroids weren’t such a big deal in Japanese MMA but they have become a huge deal in American MMA due to the media and rigid laws in the US. And it’s obvious by the lack of reporting on EPO and amphetamine usage that there definitely is some sort of bias against steroids.
