It quite literally is though I think the best example of this is currently Wesley Kitts who was popped with methylhexaneamine, basically amphetimes, and got caught. Now they say 'Well he didn't want to compete and did those drugs recreationally so we will only allow a suspension for one month' which went from July 3 to August 3, weightlifting competition starts on the 10th which is really really really opportune timing. Now before you bring anything up let me again say this:

He got popped for a competition that was mandatory for qualification for the olympics. He weighed in. He really wanted to compete and got popped. And even if he didn't attempt to stimulants like this provide more blood to skeletal muscle which in turn helps build muscle mass and this drug can and has been used to mask other performance-enhancing drugs.

The USA is getting special treatment but they are not getting enough special treatment it seems. Like they pulled this shit for a weightlifter that the last time around came 8th in his weightclass. Absolutely embarrassing show at the very least by the US weightlifting team but watching commentary on swimming, tennis and the newest 'boxing scandal' the USA should be heavily penalized but they won't.
