2023 List of Prohibited Substances
Since 2004, and as mandated by World Anti-Doping Code, WADA has published an annual List of Prohibited Substances and Methods (List).
The Prohibited List is a mandatory International Standard as part of the World Anti-Doping Program.
The List is updated annually following an extensive consultation process facilitated by WADA. The effective date of the List is 01 January 2023. The official text of the Prohibited List shall be maintained by WADA and is available for download in 8 languages. In the event of any conflict between the English and other versions, the English version shall prevail. Below are some terms used in this List of Prohibited Substances and Prohibited Methods.
Subject to a different period having been approved by WADA for a given sport, the InCompetition period shall in principle be the period commencing just before midnight (at 11:59 p.m.) on the day before a Competition in which the Athlete is scheduled to participate until the end of the Competition and the Sample collection process.
Prohibited at all times
This means that the substance or method is prohibited In- and Out-of-Competition as defined in the Code. Specified and non-Specified As per Article 4.2.2 of the World Anti-Doping Code, “for purposes of the application of Article 10, all Prohibited Substances shall be Specified Substances except as identified on the Prohibited List. No Prohibited Method shall be a Specified Method unless it is specifically identified as a Specified Method on the Prohibited List”.
As per the comment to the article, “the Specified Substances and Methods identified in Article 4.2.2 should not in any way be considered less important or less dangerous than other doping substances or methods. Rather, they are simply substances and methods which are more likely to have been consumed or used by an Athlete for a purpose other than the enhancement of sport performance.” Substances of Abuse Pursuant to Article 4.2.3 of the Code, Substances of Abuse are substances that are identified as such because they are frequently abused in society outside of the context of sport. The following are designated Substances of Abuse: cocaine, diamorphine (heroin), methylenedioxymethamphetamine (MDMA/”ecstasy”), tetrahydrocannabinol (THC).
For easy reference only, WADA has developped the digital edition of Prohibited list in the event of any conflict between this digital version and the official version (available in PDF format here), the official version shall prevail.
