When he was stopped by police 19-year-old man tried to hide cannabis in his underwear, Banbridge Magistrates Court heard last Thursday.
Daniel Battersby, The Rowans, Banbridge, was fined £250 for possession of a class B drug on April 14 this year.
The court heard that police stopped the defendant while driving on the Lurgan Road.
When they approached him he appeared nervous.
During a search they found £40 worth of herbal cannabis in his underwear. He said he had purchased it for his own personal use.
A solicitor representing Battersby said he was driving back after dropping a friend home.
In a panic he tried to conceal the drugs.
He added that the defendant had twice before received cautions for similar offences.
The solicitor said that his client was not a frequent user of cannabis but would use it when dealing with stress because of his exams.
Being in court was a sobering experience for him, said the solicitor.
District Judge, Mr Paul Copeland, said Battersby had been warned not once but twice, the last time just a week before this offence.
