A report by German researchers said that West Germany’s athletes were systematically doped with government backing from the 1970s, and possibly earlier.

The Sueddeutsche Zeitung newspaper published details from an 800-page report titled “Doping in Germany From 1950 to Today,” revealing the extent to which West German politicians were reportedly willing to promote drug use among athletes to ensure international success.

The report was compiled by researchers at Berlin’s Humboldt University on behalf of the German Olympic Sports Confederation. It was completed in April but has yet to be published because of privacy concerns and legal issues over naming athletes, doctors and politicians.
