The 2026 WADA Prohibited List & Regulatory Shift
The World Anti-Doping Agency (WADA) 2026 Prohibited List, which went into effect on January 1, 2026, introduces landmark changes to reflect new biological threats.
Carbon Monoxide (CO): The 2026 list now formally prohibits the non-diagnostic use of carbon monoxide, which athletes were using to stimulate erythropoiesis (red blood cell production).
Organelle Doping: For the first time, WADA has explicitly banned the use of cell components such as mitochondria and ribosomes to enhance cellular energy or protein synthesis.
Salmeterol Restrictions: Dosing intervals for common asthma medications have been tightened to prevent "grey-zone" ergogenic benefits while still allowing for legitimate therapeutic use.
