Smikle tested positive for the banned substance
hydrochlorothiazide, a diuretic which can mask other drugs. His
urine sample was taken at the Jamaica trials in June 2013.
The Caribbean island’s national-record holder for discus has claimed he did not knowingly or wilfully take any banned substance, and filed an appeal with the Jamaica Anti-Doping Commission.
The JADCO appeals panel upheld Smikle’s doping ban on Thursday.
Smikle threw for Jamaica at the 2012 London Olympics, but did not medal.
He was a relative unknown when he set Jamaica‘s national record of 67.12 metres earlier that year.
