US mountain biker Mock suspended for marijuana use

Mountain biker David Mock has been suspended by the US Anti-Doping Agency after testing positive for marijuana. His punishment was reduced after he successfully completed an agency anti-doping education program.

Mock, 32, tested positive on August 15 for Carboxy THC, a metabolite of THC, which is formed in the body after Cannabis is consumed.  His positive test came after racing a four cross event at the Yankee Clipper event in Windham, New York. He accepted a three-month period of ineligibility, which began on December 11. However, his sentence was reduced to time served after he completed the USADA's program on December 16.
