Madisyn Cox, the 2017 World bronze medalist in the 200m individual medley, was banned two years for testing positive for a substance she believed she ingested via tap water.
The banned substance is Trimetazidine, a medication used to treat angina, and Cox reportedly said “a world-renowned biochemist” equated her level of the substance to “a pinch of salt in an Olympic size swimming pool.”
“While the scientific expert who reviewed my case believes that I unknowingly ingested the Trimetazidine through tap water consumed the night before the test, the [FINA doping] panel determined that more scientific evidence was needed to prove this,” Cox said, according to Swimswam.
