The league has confirmed they are ‘working with’ Smith on the matter, with the ban effective immediately.
The AFL said a urine sample taken from Smith after the round 23 game versus Hawthorn at the MCG returned a positive test to cocaine.
Smith, 27 – who featured in Melbourne’s two losing finals – is aware of the result after he was informed by Sports Integrity Australia.
The maximum penalty for an in-competition test is a four-year ban.
But if Smith can prove the breach was unintentional, he will only be sidelined for a month.

‘It is asserted that a sample provided by Smith during an in-competition doping control test on 20 August 2023 returned an AAF for the presence of cocaine and its metabolite benzoylecgonine being a prohibited substance under the code,’ the AFL said in statement.
‘Smith was tested after the Round 23 Melbourne vs Hawthorn game on Sunday August 20, 2023 and was notified by Sport Integrity Australia last week in relation to the finding.
‘The AFL was made aware of the test results at the same time.
‘The matter is now progressing in accordance with the code, initially involving further investigation by Sport Integrity Australia supported by the AFL.
‘In the interim Smith will not be part of Melbourne’s football program.’
Smith forced his way into the Demons side in round 12 against Carlton and then featured in every game for the remainder of the season.
He kicked three goals in Melbourne’ semi-final loss to Carlton and became a father for the first time in September.
