The new offence introduced in July does not apply in Northern Ireland nor replace any existing offences of driving.
Article date: October 2014
In July we reported on a new offence of driving with certain controlled drugs above specified limits in the blood. This new offence will be enforceable in England, Wales, and Scotland1 but not Northern Ireland where the introduction of a similar offence is under consideration.
The new offence does not replace any existing offences of driving whilst impaired by drugs, including licenced medicines.
Please continue to warn patients of any potential driving impairment caused by a medicine and the need for caution.
