"Anabolic steroids are allowed to be used in the UAE if horses are not in training and are recovering from problems such as colic surgery or serious fractures to combat muscle wastage. Racehorses must then come to race day trace-free."

In September 2006, Sheikh Mohammed was accused of encouraging the abduction and enslavement of thousands of boys for use as jockeys in camel races. A class-action suit was filed against him in the US state of Florida. However, in 2006, American lawyers representing the UAE raised a motion to dismiss the lawsuit, not on its substance but on the grounds that none of the involved parties resided in the U.S. In July 2007, judge Cecilia Altonaga accepted the motion and dismissed the suit.

If the ruling family of a country don't have a problem kidnapping and enslaving children so they can race camels - allegedly - they're hardly likely to lose sleep over injecting steroids into horses.
