The Prohibited List of substances and methods 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 categories, together with the M methods), substances prohibited in-competition only, and substances prohibited in particular sports (category P). Alongside the List sits the Monitoring Programme: substances that are under surveillance but are not treated as prohibited. The World Anti-Doping Agency reviews and publishes this List at least once a year.
In any 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 every year, the answer depends on the version that governed on that day; for that reason previous versions are retained on this page. For the team physician, distinguishing "prohibited at all times" from "prohibited in-competition" and checking the Monitoring Programme is likewise 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.
