13. I Was High
At least Ricky Williams was honest. The 12-season NFL veteran loved marijuana so much that he fell foul of drug testers on multiple occasions. When he failed a drug test in 2006, someone asked him what had happened. His justification was that he was so high that he forgot about it. You almost have to appreciate that kind of commitment to addiction. But unfortunately, the doping committee didn’t see it that way.
Very few athletes love marijuana as much as Williams does. After the NFL suspended him in 2006, he went North to the Toronto Argonauts instead of sitting on the sidelines. When he eventually returned to the Dolphins, he tested positive for the banned substance again. You would think that he would learn if he actually wanted to play, but he just loved it too much. Still, this is one of the craziest excuses ever.
