Gardaí praised the 60,000 music fans attending the Witnness festival at the weekend saying from a policing view, the event passed without incident.
In a statement, the force said there were 244 drug seizures mostly of cannabis and ecstasy at the festival in Fairyhouse racecourse. All positive seizures would result in prosecutions, according to gardaí.
This compares with 673 drug seizures at the same event in 2001.
There were fewer arrests this year too, with only two people questioned; one for a public order offence and the second for drink driving. Last year 13 people were arrested.
