'Completely sober' drivers who smoked cannabis in last week could be prosecuted under new laws

Cannabis users who have not taken the drug for a week or more could be prosecuted under proposed new drug-driving legislation, the Transport Minister said today.

At the moment, motorists who use drugs can be prosecuted only if their driving is impaired, but this new legislation would allow gardaí to test a driver's saliva on the side of the road, followed by a blood test.
