What is the Prohibited List?

The Prohibited List is one of the binding International Standards of the world anti-doping system and determines which substances and which methods are prohibited. Its structure has three parts: substances prohibited at all times (the S classes together with the M methods), substances prohibited in-competition only, and substances prohibited in particular sports (class P). Alongside the List sits the Monitoring Programme; substances under surveillance but not deemed prohibited. The World Anti-Doping Agency reviews and publishes this List at least once a year.

About the 2024 editionChanges from the 2023 edition

Key changes from the previous edition

  1. Scope and structureThis List separates three categories: substances and methods prohibited at all times, substances prohibited in-competition only, and substances prohibited in particular sports. Alongside them sits the Monitoring Programme, which covers substances under surveillance without their being prohibited.
  2. Relationship with the CodeThis List is published under the World Anti-Doping Code, and the criteria for a substance's inclusion in it are likewise determined in the Code itself. Use of a substance appearing on this List is an anti-doping rule violation even without intent to enhance performance, unless a valid Therapeutic Use Exemption exists.
Note: for the differences between this List and the previous year's List, the authority is the "Summary of Modifications" document that the World Anti-Doping Agency publishes with each List.

Who this document matters to

In every doping case, the first question is whether the substance detected was prohibited under the List in force on the date of sample collection — and because this List changes each year, the answer depends on the edition governing that day; for that reason the previous editions are retained on this page. For the team physician too, distinguishing "prohibited at all times" from "prohibited in-competition" and checking the Monitoring Programme is essential before prescribing any medication. The official text is published in English and French and, in the event of any conflict, the English text prevails.
