Drug charges against Mix 1065's Todd McKenney have been dropped by police during a brief court hearing today.

Police discovered a vial of the drug in McKenney's pants pocket when they found him unconscious in Rushcutters Bay Park on Anzac Day, April 25, this year.

McKenney said the drugs had been planted in his pants when he took them off to have a shower at a party, at which he also said he had his drink spiked.
