The use of performance-enhancing drugs may be the biggest problem facing horse racing in the United States. A 2012 investigation reported that 3,800 horses had tested positive for drugs, the majority for illegal levels of prescription drugs.

However, recent events have triggered renewed calls for regulation of performance-enhancing drugs. This article addresses what is presently being done to combat the use of performance-enhancing drugs in the "Sport of Kings."
