Follow-up searches were carried in south-west Dublin, where a vehicle was also seized.
Four men, ranging in age from their late teens to their 40s, have been arrested.
They since been released without charge, and investigations are continuing.
A statement from a Garda spokesperson says: "Four adult males, aged in their late teens, 20s, 30s and 40s, were arrested and detained under Section 4 of the Criminal Justice Act 1984 at Garda Stations in the Dublin Region.
"All four males have since been released without charge. A file will be prepared for the Director of Public Prosecutions.
