Roadside survey of alcohol and drug use among Norwegian drivers in 2016-17: a follow up of the 2008-9 survey.

CONCLUSIONS: The proportion of samples that tested positive for alcohol had not changed since 2008-9, whereas the proportions that tested positive for benzodiazepines and amphetamines were lower. There are several possible reasons for the reduction: implementation of legal limits for 28 drugs in 2012-16, increased use of drug recognition tests, the implementation of drug screening instruments and automatic number plate recognition by the police since 2010, more focused enforcement of the DUI law, better information to drivers, and changes in drug prescriptions.
