Blog: 2018 Prohibited List released

11 October 2017

All athletes and support personnel need to be aware that the World Anti-Doping Agency has now published the 2018 Prohibited List.

The Prohibited List sets out which substances and methods are banned in sport, and is updated each year in response to scientific and medical research, trends, and intelligence gathered from law enforcement and pharmaceutical companies.

As athletes are solely responsible for all substances in their body, it is important that they are aware of upcoming changes to the List.

Its publication this month gives athletes substantial time to become aware of the changes, review any medications, and apply for a Therapeutic Use Exemption if required, well before the updated List comes into effect on January 1, 2018.

Some key changes to the List are highlighted below, however all athletes should access the full 2018 Prohibited List, as well as information about major modifications via the WADA website.

ASADA’s Check Your Substances (Global DRO) online tool will be updated in the new year when the changes come into effect.

Changes to IV infusion rules

Under the current rules, it is prohibited to receive an IV infusion greater than 50ml in a six hour period.

As of January 1, 2018, this will change to 100ml in a twelve hour period.

Specifically, IV infusions and/or injections of any substance in excess of 100 mL per 12-hour period will be prohibited at all times, except for those legitimately received in the course of hospital treatment, surgical procedures, or clinical diagnostic investigations.

It is important to note that this applies to all substances regardless of whether they are prohibited or not (including saline).

If a prohibited substance is administered via an injection or IV, a Therapeutic Use Exemption is necessary, regardless of whether the volume administered is less than 100ml.

Alcohol removed

Alcohol will be removed from the prohibited list in 2018, and is now only subject to rules of individual sports. There are some sports which explicitly state that alcohol is not allowed for safety reasons. The use of alcohol in those circumstances will be managed by the sport, not through the World Anti-Doping Code.

Glycerol removed

Glycerol will be removed from the Diuretics and Masking Agents category and will not be prohibited in 2018.

Examples of Glucocorticoids added

All glucocorticoids are prohibited when administered by oral, intravenous, intramuscular or rectal routes. On the 2018 Prohibited List, WADA provided examples of glucocorticoids that are prohibited, including but not limited to: betamethasone, budesonide, cortisone, deflazacort, dexamethasone, fluticasone, hydrocortisone, methylprednisolone, prednisolone, prednisone, triamcinolone.

Clarification of Cannabidiol

The 2018 List clarifies that synthetic cannabidiol (i.e. CBD oil) is not prohibited. However, athletes should be remain cautious about use of such products, since cannabidiol extracted from cannabis plants may contain varying concentrations of THC (THC remains a prohibited substance).
