I guess we can add Andy to the ranks...

Most horse owners, trainers, bettors and fans perceive that the widespread use of illegal drugs is ruining the sport. Yet for years, leaders and regulators of the thoroughbred industry have failed to address the problem in any meaningful way.
Drugs, including concoctions aimed at speeding muscle recovery, have debased the wonderful game of handicapping. Bettors now routinely place more emphasis on the identity of the trainer than the ability of the horse -- understandably so, when miracle-working trainers transform horses overnight and achieve winning percentages that defy all historical precedents...

... The California system may suggest that the best way to police the sport is to require that all horses go to a detention barn 24 hours before they race. Certainly, the traditional method -- testing horses after they race -- hasn't worked because the cheaters always stay a step ahead of the chemists. With effective tests for milkshakes in force, trainers looking for an edge will move on to something else. (According to racetrack scuttlebutt, some are treating horses with a painkiller 1,000 times as strong as morphine: the venom of the Conus snail, found in the Great Barrier Reef of Australia.)Instead of depending on chemists to develop tests for snail venom and other illegal substances, the sport could forestall much cheating by putting horses under strict surveillance before they compete. Most trainers -- even the honest ones -- don't like the idea of taking horses out of their normal environment before a race. Racetrack owners worry about the cost of implementing such a system. But the drug problem in racing constitutes a crisis that demands some difficult choices. Perhaps the developments in Kentucky and California signify that the industry is ready to make them.
