Ottawa – October 10, 2023 – The World Anti-Doping Agency (WADA) has published the 2024 Prohibited List that will come into effect on January 1. The 2024 Prohibited List and the Summary of Major Modifications and Explanatory Notes are now available to the sport community. 

The Canadian Centre for Ethics in Sport (CCES) encourages all athletes and support personnel to familiarize themselves with the Prohibited List and the modifications for the coming year.

Tramadol banned as of 2024

Tramadol, a commonly used narcotic, will be prohibited in competition as of January 1, 2024. Data gathered on tramadol through WADA’s Monitoring Program indicates significant use in sport. With its risks of physical dependence, opiate addiction, and overdoses in the general population, tramadol abuse is of concern and has led to it being a controlled drug in many countries. Research studies funded by WADA have also confirmed the potential for tramadol to enhance sport performance.

WADA will provide a recommended washout period for tramadol before January 1, 2024, which the CCES will communicate to the Canadian sport community. A washout period refers to the time from the last administered dose to the start of the in-competition period, at which point the substance has gone below the specified threshold or becomes undetectable.  


We caution athletes to exercise a high degree of care with regards to the use of medications, supplements, and sport nutrition products. These resources can help athletes determine whether medications are prohibited in sport, and what to do if they are.
