The seizure was made on Thursday following an investigation into the sale and supply of illegal drugs in the area.
The search was carried out in a house in the Cushlawn Park area where €2,800 worth of cocaine and €1,440 worth of cannabis was found, along with the large sum of cash which was seized on suspicion of being the proceeds of crime.
A man in his 20s was arrested at the house and has since been charged.
He is due to appear before Tallaght District Court later today.
