PROHIBITED LIST
The List of Prohibited Substances and Methods, updated annually by the World Anti-Doping Agency (WADA), is the International Standard defining what is prohibited In-Competition and Out-of-Competition. The List also indicates whether particular substances are banned in particular sports. WADA reviews and updates the List annually and the most current edition of the List is posted on WADA’s website at: https://www.wada-ama.org/en/prohibited-list (opens in new tab) . The updated Prohibited List comes into effect on 1 January every year.
Principle of Strict Liability
Under the WADA Code, athletes are held strictly liable whenever a prohibited substance is found in their urine or blood sample. A violation occurs whether the athlete intentionally, knowingly or unknowingly, used a prohibited substance.
It is therefore very important for athletes to understand not only what is prohibited, but also what might potentially cause an inadvertent doping violation.
Athletes should always check with their International Federation or Anti-Doping Singapore (ADS) to find out what additional substances and methods are prohibited in their sport. Athletes should always make their doctor aware that they are athletes and check if the prescribed medications is in the Prohibited List. Those who are unsure of what a product contains should not take it until they are sure it is not prohibited. Ignorance is never an excuse.
Medical Conditions
Athletes, may at times experience a medical condition that require them to use particular medication. The substances that an athlete may be required to take to treat a condition could fall under the Prohibited List. In such cases, by applying and obtaining a Therapeutic Use Exemption (TUE) from your International Federation or ADS, an athlete may be allowed to take the necessary medicine.
Athletes who need to apply for a TUE should request more information about the TUE application process from their International Federation (for international-level athletes) or ADS (for national-level athletes).
