Commissioned by the World Anti-Doping Agency (WADA) and carried out by the organization's former president, Dick Pound, the findings uncovered a "deeply rooted culture of cheating at all levels" within Russian athletics.
Asked if it amounted to state-sponsored doping, Pound told reporters a news conference Monday: "In the sense of consenting to it, there's no other conclusion."
The report says more than 1,400 samples were "intentionally and maliciously" destroyed by a Moscow laboratory even after a WADA plea to preserve them.
It even suggests the London 2012 Olympics -- in which Russia won 24 gold medals -- were "in a sense, sabotaged by the admission of athletes who should have not been competing."
