Justice Charles Dubin, commissioner of the Canadian government’s drug inquiry, said tests at international events failed to deter athletes from using performance-enhancing drugs.

In an exchange with Dr. Robert Dugal, head of a major doping-control laboratory in Montreal, Dugan said: “We’ve had cases where we know the athlete’s been on anabolic steroids for years . . . and been tested time and time again and they’re negative because they’re able either to mask it or to circumvent it or to clear it from the system long enough before the games itself.”
