Abstract

This study illustrates the prevalence of licit and illicit drugs among 1000 randomly stopped Danish car drivers whom the police did not suspect to be under the influence of drugs. About 98% of the stopped drivers anonymously delivered a saliva sample and 66% returned a handedout questionnaire. Confirming analyses revealed that 0.7% of the investigated saliva samples were positive for benzodiazepines and 1.3% for amphetamine, cannabis, cocaine or opiates. Questionnaire statements confirmed that some of the drivers indicate occasionally to drive despite a suspicion to be under the influence of illicit drugs (2.8%), illicit drugs including alcohol (4%), alcohol alone (24.5%) or potentially hazardous prescription drugs including alcohol (8.5%).
