"Nawaz admitted the offence and demonstrated that the substance had been used out-of-competition and in a manner unrelated to sport performance," an ICC statement said.
"The 32-year-old tested positive for a Substance of Abuse (Carboxy-THC) under the ICC Anti-Doping Code following a doping test carried out after the ICC Men's T20 World Cup 2026 match against the Netherlands in Colombo, Sri Lanka on 7 February.
Subject to Nawaz completing a substance of abuse treatment programme to the ICC's satisfaction, Nawaz will not be required to serve any further period of ineligibility.
"As required by the ICC Anti-Doping Code, Nawaz's records from the match against the Netherlands on 7 February and in subsequent matches until 1 May 2026 have been disqualified."
Nawaz played all seven games during Pakistan's T20 World Cup campaign but missed out on a contract to join Surrey to play in England's T20 Blast due to his suspension.
