Minister of Culture and Sport Stefan Wallin expects a full account from the Ski Federation on his table by May 5.
"We requested a report based on information that has surfaced in the media this week," said Wallin.
Channel Four news on Tuesday reported that illicit substance use among Finnish professional skiers was systematic in the 1990s.
The Finnish Ski Federation on Wednesday issued a statement that called for Channel Four to publicly disclose its insider sources.
