Michigan enacts steroid ban

Rules banning the presence of anabolic steroids in postrace blood samples went into effect in Michigan on Wednesday.

The rules limit the administration of anabolic steroids to four drugs that cannot be administered within at least 30 days of a race. The rules mirror those adopted by many racing jurisdictions over the past 18 months.

Michigan will take postrace blood samples to detect anabolic steroids, according to the state's racing commissioner, Christine C. White.

Michigan's only Thoroughbred racetrack, Pinnacle Race Course, will start its 2009 meet in early June. Michigan also has three harness tracks and one mixed-breed racetrack.
