It has been a year since Germany's anti-doping law came into force. Under the law, athletes who test positive for performance-enhancing drugs can face prison terms of up to three years.
The law, which came into effect last December, also provides for jail sentences of up to 10 years for those who provide the athletes with performance-enhancing substances.
No athletes have yet been prosecuted under the new law but according to the chairwoman of the German parliament's standing committee on sports, Dagmar Freitag, some investigations are underway.
The Social Democrat member of the Bundestag also told DW that one year is not a long-enough period to determine whether it has been a success or a failure. Doping cannot be wiped out completely, she said, but the fight is an important one.
She also said that she wasn't surprised by the findings of the second McLaren Report, released earlier this week, which said that more than 1,000 Russian athletes were involved in or benefited from widespread doping manipulation.
