Police received a report of a strong smell of cannabis coming from a room at a property at Portstewart’s Coleraine Road.
And when they swooped they found a man was in possession of the Class B drug.
The incident involving Jamie Richard Leslie (20), of Boleran Road, Garvagh, came to light on June 13 of this year, Coleraine Magistrates Court was told last week.
A defence solicitor said her client “accepts he has had a bit of a probem with cannabis”.
But she added that he has now gone to see his GP about the issue.
The defendant pleaded guilty to possession and was fined £200.
