Ms Liz O'Donnell:

We are playing catch-up and it has been a problem for some time. Due to increased detection because of Garda checkpoints and visible Garda presence, the incidence of drug-driving is now almost the same as for drink-driving. Fortunately, we have been able to provide the technology to detect drug-driving on the roadside, which has led to the increased incidence detection. We need more of this and we will support such action. It is a current problem.
