Cocaine is listed under Class S6 (Stimulants) of the World Anti-Doping Code – International Standard – Prohibited List 2026 (2026 Prohibited List).
Cocaine is prohibited In-Competition only and is a Non-Specified Substance. Cocaine is also classified as a ‘Substance of Abuse’ under the 2026 Prohibited List.
In accordance with Article 10.2.4.1 of the Tennis Anti-Doping Programme, the ITIA imposed a one-month period of Ineligibility on Mr Kyrgios, commencing from the date of his provisional suspension on 4 August 2026.
Mr Kyrgios was ineligible to participate in any sports that have adopted a World Anti-Doping Code compliant anti-doping policy until 11:59pm on 3 September 2026.

Additional information on the Prohibited Substance
Classified by the World Anti-Doping Agency (WADA) as an ‘S6 Stimulants’ class of illicit drug, cocaine is an illegal substance listed on the Prohibited Substances and Methods list under the Substances of Abuse category, as a drug which is prohibited for use ‘In-Competition’.
Stimulants are a class of drug that accelerate the function of the central nervous system. They stimulate the sympathetic nervous system which causes an increase in body temperature, heart rate, blood pressure and affects respiratory rate.
They also suppress sensations of hunger, thirst and fatigue which when combined with sharp rises in body temperature result in an increased risk of dehydration, complete exhaustion and death.
