The jockey has accepted the suspension and will be free to ride again on 19 May 2013.
Dettori gave the positive test in September, at a day of major trials for the following month’s Prix de l'Arc de Triomphe meeting. The subsequent six-month suspension, which will apply worldwide, was confirmed by France Galop’s medical body.
The ban, backdated to 20 November 2012, will run until 19 May 2013. The British-based Italian star has decided not to appeal against the decision.
His solicitor Christopher Stewart-Moore said: “Frankie fully accepts the ban. He has acknowledged to France Galop that he has made a mistake and that the fault was his. He knows that his privileged position brings with it responsibility.
"Frankie could make excuses but the responsibility for his current situation lies squarely with him. He has asked me to thank everyone for the many messages of support he and his family have received.”
As a result of the ban, Dettori will miss the entire Asian season, the Dubai World Cup and the start of the British Flat season. He will be back in time for the Oaks, the Derby and Royal Ascot.
Now 45 and a freelance jockey after parting company with Godolphin at the end of October, Dettori faces the task of finding quality rides to match his status, and for the next six months at least will leave the limelight he has occupied for more than 25 years open for his young rivals.
