Horse Racing: Meeznah disqualified after failing the dope test

Question

Anyone tell me that why Meeznah disqualified after failing the dope test?

Answer 1

Meeznah was the second place finisher in the Group I Investec Oaks that kicked off at Epsom on the 4th  of June, under the care of trainer David Lanigan. Lanigan was demanded by the British Horse Racing Authority after his horse Meeznah was tested positive for the banned chemical acepromazine on the 25th of Novembe.It is very unfortunate that the filly could not retain her position in the Oaks despite her struggled second finish against Snow Fairy in the meet. Meanwhile Meeznah was officially disqualified, her trainer Lanigan was also fined for 750 pounds on Thursday morning.
