Sergeant Maria Callaghan previously told Blanchardstown District Court that gardaí were operating a checkpoint when they stopped a black Audi A3.
She said there was an overwhelming smell of cannabis coming from the car, and when it was searched gardaí found cannabis, with a street value of €850, in a money lodgement envelope hidden in the side pocket of a sports bag.
Pleimean co-operated fully with gardaí and admitted possession of the cannabis, the sergeant added.
Defence solicitor Simon Fleming said that Pleimean, a father of one, accepted the valuation of the cannabis but he had only paid €300 for it.
Mr Fleming previously told the court that Pleimean was attending a hospital appointment with his son in Dublin and he took an opportunity to collect the cannabis.
