Don’t horses race on drugs?

Racing has a principle of ‘drug free’ racing. Under the rules of Australian racing, no horse is allowed to run in a race whilst under the influence of any medication, including anti-inflammatories, steroids, hormones and diuretics.

Horses are regularly tested, before and after races and in and out of training, ensuring racing is as clean as possible.

So, there's no drugs in racing?

Not quite… 

Drugs, medications and treatments are used in the training of horses, much like human athletes. 

Mild, non-steroidal anti inflammatories such as aspirin, or the more horse-specific pain relief medication phenylbutazone (known as ‘bute’), are commonly used to aid in the recovery of sickness, pain and inflammation, just as humans turn to paracetamol and ibuprofen. 

Corticosteroids are sometimes used for the relief of joint pain in racehorses. These aren’t the same as anabolic steroids (the kind used by some bodybuilders), which are strictly prohibited.

Rigorous testing processes

Horses are tested routinely at the races and in and out of training. 

Registered vets, working on behalf of the stewards, take blood samples, looking for the presence of medications in their system. If a horse has received a medication in training, there may still be traces of that medication in their system – as with humans, medications will work their way out of the body over slightly different time frames.

All of the permitted medications come with advised ‘withdrawal periods’ – the recommended number of days before a race that a horse should not be given that medication, so that it’s not affecting the horse on race day. However, even when those withdrawal periods are correctly followed there may still be traces of previously administered, so, just like with human athletes, there are ‘screening limits’ for substances detected.

Keeping record

Trainers are required to keep a record of any medication or treatment administered to any horse in their care on a daily record. Stewards can inspect these records at any time, and fines and penalties are given out if trainers aren’t following the steps they should be.

Anabolic steroids are strictly prohibited in and out of training, and any registered horse may be tested by stewards at any time – horses can even be tested as foals and at horse sales.

The bad dudes

Racing is constantly working to keep the sport clean, just like athletics, cycling – indeed all sports. Unfortunately, there will always be a tiny minority who will try to break the rules, but racing pours enormous amounts of money and resources into testing. 

Just one state, NSW, conducted a total of 113,507 tests in the 2020/21 season alone.

So, the cheats are rare, but when they do come along they are severely penalised and often ostracised by other industry participants. 

In a landmark 2018 case, trainer Robert Smerdon was banned for life, bringing his career to an end, and fined $100,000 for systematic cheating.

Non-equine athletes

It’s not just horses that are tested – jockeys, trackwork riders and stablehands are all licensed and therefore liable to be regularly tested for both drugs and alcohols by stewards. They will receive fines and bans too if they are found to have any prohibited or undeclared substances in their system.
