California has been at the forefront of medication reform.
In 2008, California was among the first states to ban anabolic steroids in racehorses, and California was also one of the first states to adopt the <a href=”http://rmtcnet.com/national-uniform-medication-program/”>RMTC National Uniform Medication Program</a>, which restricts the use of several medications and imposes limitations on the use of corticosteroids. California was also the first state to adopt a rule giving the CHRB authority to greatly restrict the overuse of the therapeutic medication clenbuterol at racetracks.
Racehorses are subject to extensive drug testing both in and out of competition. The Kenneth L Maddy Equine Analytical Chemistry Laboratory at UC Davis provides California racetracks with a comprehensive drug testing program that checks for more than 1,500 substances and regularly exceeds the Thoroughbred Owners and Breeders Association “Super Test” criteria. As new information becomes available, new analytical tests are added to the post-race testing regimen. The laboratory has a world renowned program in equine pharmacology research.
