Questionnaires and biomarkers are used to estimate the extent of cannabis use within a designated population, but, it is not clear what screening instruments or biomarkers should be the option of choice. This study compares three screening questionnaires with two different biomarkers in order to investigate their usefulness in the detection of cannabis use. This study shows that the CAGE-AID and ProbCannabis-DT are two valid screening questionnaires in the detection of cannabis use compared to biomarkers in hair and plasma. Based on our results, biomarker analyses detect much fewer cannabis users than questionnaires.
