British sprinter Nigel Levine has been suspended from all sport for four years after testing positive for banned asthma drug clenbuterol, UK Anti-Doping has announced.
The 29-year-old tested positive for the prohibited substance following an out-of-competition test on November 24 last year.
It emerged in February that he had been charged with committing an anti-doping violation and provisionally suspended.
In its announcement of the four-year ban on Tuesday, UKAD said Levine's suspension would be backdated to December 13 2017, the date of the provisional suspension, and run until December 12 2021.
Widely used to treat breathing problems, clenbuterol has also been abused by athletes and bodybuilders to burn fat and boost aerobic capacity, hence its place on the World Anti-Doping Agency's prohibited list.
