Prohibited List

The WADA 2026 List of Prohibited Substances and Methods came into force on 1 January 2026. Athletes are ultimately responsible for any prohibited substance found in their system or any prohibited method used.

Key changes for 2026

• Additional examples help identify prohibited substances in four categories: anabolic agents, peptide hormones and growth factors, hormone and metabolic modulators, and stimulants.
• The non-diagnostic use of carbon monoxide has been added as a prohibited method.
• Salmeterol dosing intervals have been adjusted while the maximum daily dose is unchanged.
• The prohibition explicitly covers cell components such as mitochondria and ribosomes.
• Rules on withdrawing blood and blood components have been clarified.
