Drug driving offences are a growing area of prosecution in Ireland. They cover both impairment-based charges (where a garda forms an opinion that a driver is impaired) and charges based on the detection of a specified controlled substance above the legal limit, typically confirmed through roadside oral fluid testing followed by a laboratory blood test. These cases often turn on technical and procedural detail: the administration of the roadside test, the handling and testing of the blood sample, and the qualifications of those forming an opinion of impairment.
Gardaí currently test at the roadside for the following drugs using an approved device:
- Cannabis
- Amphetamines / Methamphetamines
- Ketamine
- Opiates
- Cocaine
Killian advises clients at every stage, including:
- What your rights are during a roadside stop and at the Garda station, and how to protect yourself without obstructing gardaí
- Whether the correct testing procedure and timelines were followed, including the two-stage testing process common in drug driving cases
- Challenging testing methodology or documentation where there are grounds to do so
- Preparing a clear, evidence-based mitigation strategy for court, particularly important for professional drivers, shift workers, and anyone whose job or family depends on retaining their licence
Because these prosecutions can involve complex toxicology and procedural evidence, early legal advice, ideally before you're interviewed or make any statement, can make a real difference to the outcome.
In drug driving prosecutions it is normal procedure for a driver to be detained pending a blood or urine sample being given. You will normally be released pending analysis of the sample. Current practice is for gardaí, once in receipt of a Certificate of Analysis from a State-approved laboratory, to begin the prosecution by way of court summons.
