The list of banned substances and methods (Prohibited List) is usually published annually by the World Anti-Doping Agency (WADA) and enters into force on 1st January of each year. The Prohibited List is one of WADA's six International Standards, the implementation of which is mandatory for all signatories of the World Anti-Doping Programme.
It is the responsibility of all athletes to ensure that they consult the currently valid Prohibited List and find out about the specific regulations of their authority.
Every year Antidoping Switzerland publishes the Prohibited List that applies to Switzerland in German and French. A printed version of this list may be obtained free of charge from Antidoping Switzerland.
In addition to the Prohibited List, a list is available of permitted, non-prescription medicines and drugs for the treatment of common illnesses in Switzerland. In order to avoid unintentional doping violations with medicine, it is recommended to consult the practical drugs enquiry Global DRO.
New from 2020: changes to the Prohibited List
The World Anti-Doping Agency (WADA) has mainly made formal changes to the 2020 Prohibited List and added examples of prohibited substances or their synonyms. All these newly listed substances were already prohibited in the sense of «similar chemical structure» or «similar biological effect». A comprehensive list of all changes is provided by the WADA.
In practice, this means that all changes have no impact on the doping status of medications available in Switzerland.
One of the sections, which has been formally adapted for the Prohibited List 2020, is the class of the cannabinoids, substances prohibited in-competition. The change, however, has no effect on their doping status, i.e. all natural and synthetic cannabinoids remain prohibited. The only exception is the pure substance cannabidiol (CBD).
However, this does not mean that athletes can consume CBD products without hesitation, as CBD products also contain a certain amount of tetrahydrocannabinol (THC), which is prohibited in competition. Antidoping Switzerland therefore warns against the use of CBD products: Warning of CBD products
