A 34 year-old local man appeared before Dundalk Court on Wednesday after Gardai found a small bag of cannabis herb in the glove department of a car.
The Gardai carried out a search of the vehicle after detecting a smell when they stopped it at Bellewsbridge Road.
Fergal Sheehy of Mary Street South was charged with possession of €20 worth of the drug and insurance and driving licence offences.
Judge James Faughnan applied the probation act in respect of the drugs matter, but convicted and fined the defendant €200 and banned him from driving for four years for not having insurance. He also convicted and fined him €100 in respect of the driving licence.
Garda Inspector Brendan Cadden said that Gardai on patrol on March 4 last year stopped the defendant.
The defendant told Gardai that he knew what was in the bag and it was for his own use. He was asked to produce insurance and driving licence.
Frank McDonnell solicitor said a co-accused was prosecuted for possession of the drugs, and received the probation act.
The defendant had only recently bought the vehicle for little or no money.
