Rio 2016: Performance-enhancing and banned drugs explained - Sport. By Catherine Hanrahan Updated Olympic swimmers have caused a storm by calling out Rio competitors who have previously been banned for returning positive drug tests.
Australian swimmer Mack Horton dismissed Chinese simmer Sun Yang, who was banned for three months for taking trimetazidine, as a drug cheat.
