This is definitely something that should be looked at. Doping enhances your performance, so does messing with equipment. Like in cross-country skiing: if your skis are positive for fluor, you get a DQ for that competition, but that's it (or you can even have them tested before the race and have no punishment at all, like two of the Brazilians in the Trondheim world championships having their skis test positive, likely due to using fluor in a race in January where it was announced there would not be a fluor test). If your urine tests positive for EPO, the problem is significantly bigger.
