4. Sanction Verdict & Legal Matrix Nick Kyrgios

ELIGIBLE TO COMPETE Retroactive Time Served

Immediate Clearance (Cleared to Return)

1 Month (Satisfied)

Governing Rule: WADA Code Art. 10.2.4.1

Because cocaine is classified as a Substance of Abuse and ingestion was established as occurring out-of-competition without performance-enhancing intent, the standard multi-year ban is reduced to 3 months, and further down to 1 month upon completion of an approved substance treatment program.

Precedent Benchmarks

Player	Substance	Defense & Outcome
N. Kyrgios (2026)	Cocaine	Art. 10.2.4.1 Out-of-comp abuse; completed rehab → Cleared
R. Gasquet (2009)	Cocaine	Nightclub kiss micro-trace; CAS found No Fault → Exonerated
J. Sinner (2024)	Clostebol	Physiotherapist Trofodermin spray; No Fault/Negligence → 0-month Ban
Hypothetical In-Comp	Cocaine	In-competition match detection → 2 to 4 Years Ban

Legal Principle (2021 WADA Code Reform): Article 10.2.4.1 was created specifically so that recreational drugs taken socially outside competition are treated through health & rehabilitation channels rather than devastating multi-year sporting bans.
