2026 List of Prohibited Substances and Methods and the 2026 Monitoring Program are in force from 1 January 2026
The World Anti-Doping Agency (WADA) announced that the 2026 List of Prohibited Substances and Methods and the 2026 Monitoring Program are in force from 1 January 2026.
It designates which substances and methods are prohibited both in- and out-of-competition and which substances are banned in particular sports.
The 2026 Monitoring Program includes substances that are not on the List, but that WADA wishes to monitor in order to detect potential patterns of misuse in sport.
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.
