Since 2004, the World Anti-Doping Agency (WADA) has been responsible for the preparation and publication of the list of substances and methods that are prohibited in sport, known as the Prohibited List.
It is one of five International Standards that identifies substances and methods prohibited in- and out-of-competition, in-competition only, and in particular sports. The substances and methods on the List are classified by different categories (such as steroids, stimulants, or gene doping).
An athlete may be permitted to use a prohibited substance or method for medical reasons, if they obtain a Therapeutic Use Exemption (TUE).
The Prohibited List is updated annually following an extensive consultation process facilitated by WADA. Additional substances or methods may be added to the List at any time during the year but this will only occur after a three month notice period.
The main changes to The List for 2018 include:
Clarification regarding salbutamol inhaler dosing parameters
The dosing parameters of inhaled salbutamol have been clarified to make it clear that doses of salbutamol should not exceed 800 micrograms over any 12-hour period. Please refer to the WADA 2018 Summary of Major Modifications and Explanatory Notes for further information.
Glycerol to be removed from the List
Glycerol will no longer be prohibited in 2018 after being removed from the Diuretics and Masking Agents section of the List.
Changes to intravenous (IV) infusion rules
The allowed volume and timing of intravenous infusions will increase from infusions of no more than 50 millilitres (mL) per 6-hour period in 2017 to no more than a total of 100 mL per 12-hour period in 2018.
More specifically, IV infusions and/or injections of any substance in excess of 100 mL per 12-hour period will be prohibited at all times in 2018, except for those legitimately received in the course of hospital treatment, surgical procedures, or clinical diagnostic investigations. If a prohibited substance is administered intravenously or via injection, a TUE will continue to be necessary for this substance regardless of whether the infusion or injection is less than 100 mL.
Additional examples of stimulants
1,3-Dimethybutylamine (DMBA) will be added as an example of a stimulant under section 6 of the 2018 List. Athletes should remain vigilant regarding this substance as it can be found in some dietary supplements. UKAD’s position on dietary supplements can be found here.
Clarification regarding the status of cannabidiol
The WADA List Expert Group have confirmed that synthetic cannabidiol (i.e. CBD oil) is not a cannabimimetic and is therefore not prohibited under S8 Cannabinoids. However, athletes should be cautious about use of such products as cannabidiol extracted from cannabis plants may contain varying concentrations of THC (THC remains a prohibited substance).
Examples of glucocorticoids (S9) to be added
The 2018 Prohibited List will name some examples of commonly used glucocorticoids for greater clarity (refer to the 2018 List for further details).
Alcohol to be removed from the List
Alcohol will no longer be prohibited in 2018. The International Federations of Air Sports, Archery, Automobile, and Powerboating will be able to apply and enforce protocols for alcohol use as they see fit.
