The Prohibited List is one of the mandatory International Standards of the global 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 that are not treated as prohibited. The Agency reviews and publishes this List at least once a year.
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 on that day; for that reason earlier editions are retained on this page. For a team physician, distinguishing "prohibited at all times" from "prohibited in-competition" and checking the Monitoring Programme is equally essential before prescribing any medication. The official text is published in English and French, and in case of conflict the English text prevails.
