The Queensland Racing Integrity Commission (QRIC) released a statement on Thursday that detailed the transgressions, which includes cobalt in excess of the prescribed threshold in samples taken from greyhounds that raced at Brisbane, Capalaba and Ipswich in October and November last year.
Three positive Phenobarbitone samples were returned for the greyhounds Nikki Nettle, Power Service and Jeannie Dreaming and two positive cobalt samples in excess of the prescribed threshold were found in Nikki Nettle and Power Service.
Dacey pleaded guilty to all charges and the stewards disqualified him until 12 December of this year.
In addition to his training disqualification, Nikki Nettle, Power Service and Jeannie Dreaming were expunged from their respective events with placings amended. All prize money accrued by the trio is also to be returned.
The QRIC has granted Dacey two weeks to transfer any registered greyhounds out of his name.
