Press Release

30th January 2018

USADA announced today that Marck Harrison, of Columbus, Ohio, an athlete in the sport of Paralympic boccia, has accepted a public warning for failing to obtain a Therapeutic Use Exemption (TUE) prior to his use of an otherwise prohibited medication. Harrison’s violation resulted from his use of a prescription medication containing chlorthalidone – a prohibited substance on the World Anti-Doping Agency Prohibited List – which he was using under the care of a physician. Harrison, 38, had forthrightly declared the use of his medication on his doping control form at the time of sample collection and subsequently obtained a TUE authorizing future use of this medication in sport.
