The new Prohibited List comes into effect as of 1 January 2020. The World Anti-Doping Agency (WADA) has mainly made formal changes. The changes have no impact on the doping status of medications available in Switzerland.

Antidoping Switzerland reminds all athletes to check all medications with the Medication Inquiry Service Global DRO (via website or Mobile App) before use.

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). The recommendation of Antidoping Switzerland to athletes remains unchanged: Do not consume CBD products derived from the cannabis plant as they contain a certain amount of THC. THC is a substance prohibited in competition, which can lead to a positive doping test.
