Statement attributable to Nicholas Delpopolo:

"My positive test was caused by my inadvertent consumption of food that I did not realize had been baked with marijuana, before I left for the Olympic Games. I apologize to U.S. Olympic Committee, to my teammates, and to my fans, and I am embarrassed by this mistake. I look forward to representing my country in the future, and will re-dedicate myself to being the best judo athlete that I can be."
