This technical document was developed by HISA’s ADMC Standing Committee and approved by the Horseracing Integrity & Welfare Unit (HIWU), which will administer the program. In a memorandum to racing participants, HISA ADMC Committee Chair Adolpho Birch summarized the contents of the document submitted, which underwent several modifications based on substantive feedback from racing participants and experts during a public comment period before submission to the FTC.

“The Prohibited Substances List is the result of extensive consultation with industry and subject matter experts and is informed by established research. Once approved by the FTC, it will serve as the backbone of HISA’s ADMC Program set to take effect in the New Year,” said Birch. “Through our collective efforts led by the ADMC Committee, we are proud to introduce U.S. Thoroughbred racing’s first-ever uniform Prohibited Substances list that will be applied on a national basis to advance integrity, transparency and accountability in the sport.”

“Effective anti-doping programs require clear guidance on prohibited substances, and we are pleased with the document that was submitted to the FTC,” said Ben Mosier, executive director of HIWU. “This list will play a key role in HIWU’s assignment to enforce HISA’s ADMC Program, and we are prepared to take on this critical responsibility on behalf of the Thoroughbred industry.”

In addition to listing and categorizing all prohibited substances covered by the ADMC Program, the document details detection times, screening limits and thresholds. The modified document submitted to the FTC is available on the HISA website.
