The new chief executive of UK Anti-Doping has vowed to focus on the increasing problem of teenage use of anabolic steroids in sports like rugby. She is concerned this problem could worsen during the upcoming Rugby World Cup in England. UK Anti-Doping has suspended 13 rugby players out of the last 15 doping violations, and at least 50 doping bans have involved British rugby players, including the son of a former professional player who tested positive for two steroids at a training session.
