- Deputy Réada Cronin asked the Minister for Transport the current legal limit for cannabis found in a driver's system; and the legal ramifications this limit could potentially have on an individual who has consumed cannabis days before operation of a vehicle. [76673/26]
Seán Canney, Minister of State at the Department of Transport: As Minister for Transport, I wish to inform the Deputy that the legal limit for cannabis and driving is set out in Section 8 of the Road Traffic Act 2016. The limits are:
- 9-Tetrahydrocannabinol (Cannabis) 1ng/ml
- 11-nor-9-carboxy-9-tetrahydrocannabinol (Cannabis) 5ng/ml
Cannabis is an impairing substance which greatly increases the risk of dangerous driving. If a driver is convicted of exceeding the legal limit, they may be disqualified for at least one year for a first offence, and at least 2 years for a second or subsequent offence. On summary conviction, there is a fine of up to €5,000 and/or up to 6 months imprisonment.
The legal ramifications for a person who has consumed cannabis before operating a vehicle are dependent on blood concentration. Impairment can continue for significant periods and there is no residual use defence in statute. I have no intention of changing the current position.
