The World Anti-Doping Agency has published the updated List of Prohibited Substances and Methods, entering into force on 1 January 2026.
WADA and WFDF strongly encourage athletes, coaches, support staff, and all sport stakeholders to review the List and Summary of Major Modifications carefully to avoid any violations.
Please find below further information:
Major Modifications for 2026
As outlined in the 2026 Summary of Major Modifications and Explanatory Notes, the major modifications for 2026 include the following:
Further examples or clarifications have been added to the following substance classes to help athletes and their entourage better identify prohibited substances:
S1. Anabolic agents,
S2. Peptide hormones, growth factors, related substances, and mimetics,
S4. Hormone and metabolic modulators, and
S6. Stimulants.
The dosing intervals of salmeterol have been changed to avoid potential ergogenic effects, though the maximum daily delivered dose remains the same.
More details have been given about the prohibition of withdrawal of blood and blood components.
The non-diagnostic use of carbon monoxide (CO) has been added to the Prohibited Methods as a new section, M1.4. The use of carbon monoxide for diagnostic purposes, such as total hemoglobin mass measurements or the determination of pulmonary diffusion capacity, is not prohibited.
Cell components (e.g., nuclei and organelles such as mitochondria and ribosomes) have been added to the existing prohibition of using normal or genetically modified cells.
It has been clarified in the Glucocorticoids Washout Table that use of sustained-release formulations may result in detectable glucocorticoid levels past the washout period due to prolonged systemic absorption.
The List is released three months ahead of it taking effect so that athletes, their entourage, and other stakeholders can acquaint themselves with any modifications. Ultimately, athletes are responsible for prohibited substances found in their body and prohibited methods found to have been used. Members of an athlete’s entourage are also liable for Anti-Doping Rule Violations if determined to be complicit. Consequently, if there is any doubt as to the status of a substance or method, it is important that they contact their respective Anti-Doping Organizations (International Federation or National Anti-Doping Organization) for advice.
Therapeutic Use Exemption Program
It should be noted that athletes who have a legitimate medical reason for using a prohibited substance or method that is on the List can apply for a Therapeutic Use Exemption (TUE) to determine whether they meet the criteria outlined in the International Standard for Therapeutic Use Exemptions (ISTUE).
