Depending on who you ask, you'd come away thinking its ubiquitous. People pop all the time, for one thing. The UFC dropped USADA and instead went with some less standard testing when Connor McGregor was set to make a return. There was also a fun story about Nick Diaz vs Anderson Silva. Silva, known as a legendary unstoppable monster, ends up popping for PEDs, so Diaz was going to be declared the winner, but it turns out Diaz popped for weed. He was so hot that there was no way he wasn't high during the fight.
