Experts are questioning the severity of a zero-tolerance policy towards those caught driving with detectable levels of illegal drugs in their bodies, as some drugs, such as cannabis, can be detected long after their effects have worn off.

The experts have voiced their concerns following the news last week that the police have started using a new mobile drug testing kit called the ‘narkometer‘, which can detect traces of seven different drugs in people’s saliva.

Those testing positive while driving face a three-year driving ban and a fine equivalent to four percent of their gross annual pay.

But according to Sundhedsstyrelsen, the national health authority, traces of the active ingredient in cannabis, THC, can be detected in a person’s body for up to eight weeks after they have used the drug.

The result is that people can be fined and lose their driving licence long after they have sobered up from the effects of the drug.
