From their website…

The Water Hay Oats Alliance (WHOA) is a grassroots movement of like-minded individuals who support the passage of federal legislation to prohibit the use of performance-enhancing drugs in the sport of horse racing. The appointment of an independent anti-doping program run by the U.S. Anti-Doping Agency (USADA) will resolve the problem of widespread drug use in American racing and put U.S. racing jurisdictions in step with international standards.

Doping destroys public confidence in racing, defrauds the betting fan, weakens the genetic pool and, most importantly, puts the life and limb of our equine athletes and their jockeys at risk. It is obvious that after years of committee review and discussion, America’s racing industry cannot police itself by eliminating the proliferation of performance-enhancing drugs in our sport, nor does it possess the power to adequately punish the purveyors of these drugs.

Founded in 2012, WHOA is a group of like-minded Owners, Breeders, Trainers, Jockeys, Equine Practitioners, Industry Professionals, Handicappers and Racing Fans who stand against the permissive use of performance enhancing drugs in American horse racing.
