A small amount of suspected cannabis was seized in Carndonagh last night.
The seizure was undertaken by Buncrana Roads Policing Unit who were conducting a patrol in Carndonagh overnight when they detected the smell of cannabis from a car.
The driver tested positive for the presence of cannabis and was arrested.
Gardaí in Donegal have reminded people to never drive while under the influence of alcohol and/or drugs.
They said that the result of this behaviour can be utterly devastating with one poor decision having the potential to change the life of the offender and others.
