All banned substances and methods in Code-compliant sports, including football, are outlined in the Prohibited List. Substances and methods can be added to the Prohibited List at any time; however, it is updated as a minimum once a year, coming into effect on 1 January. 

The latest Prohibited List can be found on the WADA website. As this list is updated frequently, Players and other Participants should make sure they check it regularly for any changes.
