LAKE PLACID, N.Y. (AP) The U.S. Anti-Doping Agency says former USA Luge athlete Riley Stohr has been suspended for six months because he tested positive for a metabolite found in marijuana.
Stohr's ineligibility is retroactive to March 18, when he tested positive for THC at national seeding races in Lake Placid. His retirement from the sport was announced by USA Luge about two months later.
USADA said Thursday that Stohr acknowledged using the prohibited substance.
USA Luge CEO Jim Leahy says the team has accepted the 21-year-old Stohr's resignation, and ''wish him nothing but the best as he moves his life forward.''
Stohr was the 2013 USA Luge Youth National Champion. He did not compete internationally last season because of a shoulder injury, and was on the World Cup circuit briefly in the 2014-15 season.
