Cocaine worth €140,000 has been found by officers during a search in Lucan.
The raid was planned by Gardai, and carried out at 7PM on Wendesday evening.
A 20-year-old woman was arrested, and questioned by officers at Ronanstown Garda Station.
She has since been released from custody without charge.
In a statement, the Gardai said "These operations use advanced analytical and intelligence methods to disrupt criminals and dismantle their networks."
"Drug seizures also help protect communities from the devastating impact of drugs and the associated criminality", they added.
