Protecting the Right to Enjoy Doping-Free Sport

Banned Substances in Sport

banned substances

The Prohibited List is the universal list of all substances and methods that are banned in sport.

They are arranged in categories, some of which will be familiar to you, such as steroids or stimulants. 

It is important to note that the Prohibited List is updated annually and published every January. However, substances can be added to the list at any time, so make sure you check it regularly.

What is included in the Prohibited List?

Both substances and methods (such as blood doping) are included in the Prohibited List. They will be included if they meet at least two of the following criteria:

  • Potential to enhance sports performance
  • Actual or potential health risk to an athlete
  • Its use violates the spirit of sport.

Some substances or methods are included on the List because they have the potential to mask another prohibited substance or method.

What is the difference between in-competition and out-of-competition on the Prohibited List?

The Prohibited List details substances that are banned at all times and those banned during competition only (in-competition). Athletes should be cautious and remember the following:·

  • Even if an athlete took a substance out-of-competition, if it is present in their sample for an in-competition test, it can result in an Anti-Doping Rule Violation (ADRV)
  • Different substances will stay in the system for different lengths of time. This can range from hours to months
  • It is difficult for medical staff to advise on the time it takes for a substance to pass through someone’s system, as it will differ from one athlete to another
  • The safest way of being confident you have no substances in your system that are prohibited in-competition is to try and avoid them at all times. 

Remember – always check your medications, even if you have checked previously. New substances can be added to the Prohibited List at any time.
