Following an extensive consultation period by WADA, the 2023 Prohibited List was published on 29 September 2022. This gives athletes and their support personnel sufficient time to make themselves aware of the changes, review any medications they use, and apply for a Therapeutic Use Exemption (TUE) if required before the updated List comes into effect on 1 January 2023.

Additional Examples:

While no major changes have been made, further examples of prohibited substances have been added to various categories of the 2023 Prohibited List.

WADA has also published the 2023 Monitoring Program which lists substances (not on the Prohibited List) that are currently being monitored for potential misuse.

UKAD will be making resources available to National Governing Bodies to assist in reminding their athletes of what they need to do ahead of 1 January 2023.


Separately, WADA’s Executive Committee approved the List Expert Advisory Group’s recommendation to prohibit the narcotic tramadol in-competition, effective as of 1 January 2024.
