  • The Norwegian Institute of Public Health analysed blood samples from a total of 8,173 cases in which drivers were suspected of driving while impaired. This is a decline from 8,550 cases in 2013. In addition, the police took 1,850 local breathalyser samples using Evidenzer instruments.
  • In about 2,300 cases, the police sent blood samples to the Norwegian Institute of Public Health for pure alcohol analysis. This is a decline from about 3,200 pure alcohol analyses last year. The number of breathalyser samples has simultaneously increased from around 1,350 to 1,850, which means that there were approximately 400 fewer alcohol samples taken in 2014 than in 2013. In cases where only alcohol was analysed, 98 per cent of the samples tested positive.
  • In about 5,850 cases, the samples were tested for alcohol and over 40 different drugs and narcotics. This is an increase from 2013 when there were about 5,300 cases.
  • In the cases where alcohol, intoxicating drugs and narcotics were analysed, 92 per cent of the blood samples contained one or more of these substances. On average, about three different substances were detected in the same blood sample.
  • Compared to previous years, more amphetamines than methamphetamines were detected.
  • More of the newer drugs, such as synthetic cannabinoids and other new psychoactive substances were found compared to previous years.
  • More cocaine was detected in Oslo than in the rest of the country.

Alcohol in every other sample

As in previous years, alcohol was the drug most frequently found in blood samples from drivers suspected of driving while impaired (49 per cent of total cases), followed by cannabis. Other substances that were frequently detected were amphetamine and the benzodiazepine clonazepam (active ingredient in Rivotril). The incidence of the most common drugs has changed little compared to previous years.
