The Thoroughbred Horsemen's Association hopes to release a sweeping national medication and drug-testing proposal either before or during the University of Arizona Symposium on Racing, which begins Dec. 4.On Thursday, the National Horsemen's Benevolent and Protective Association offered its proposal on national drug testing and therapeutic medication."We welcome (the HBPA) proposal, and it's certainly worthy of debate," said Alan Foreman, chief executive officer of the THA, which has affiliates in five states. "It doesn't contain much new, because those thresholds (for therapeutic medications) are already in place in some states. We'll have to look at the scientific support for those."Foreman said the THA will issue a "comprehensive report on medication" this fall. "It's a different approach, but one we think will get widespread support. We're going to share the recommendations with a broad base of the industry."The THA medication report will involve regulators and the scientific community, Foreman said, "so it doesn't look like the proposal is just coming from the THA."The THA, with about 20,000 members, has affiliates in Delaware, Illinois, Maryland, New Jersey, and New York. The organization recently threw its weight behind the National Thoroughbred Racing Association's Racing Integrity and Drug Testing Task Force, which issued a report on drug-testing standards in August.
