The 2023 Prohibited List is Now in Effect

Ottawa – January 3, 2023 – The Canadian Centre for Ethics in Sport (CCES) reminds the Canadian sport community that the World Anti-Doping Agency’s (WADA) 2023 Prohibited List came into effect January 1, 2023.

Minor changes were made to the 2023 Prohibited List, primarily related to examples, clarifications, and harmonizing language. A full list can be found in the Summary of Major Modifications and Explanatory Notes.

WADA also gave advance notice that the narcotic tramadol (S7) will be prohibited in competition effective January 1, 2024. The delay in implementation will allow athletes and medical personnel to better prepare for the change, laboratories to update their procedures, and sports authorities to develop educational tools.


We caution athletes to exercise a high degree of care with regards to the use of medications, supplements, and sport nutrition products.
