7. In 2004 MORI and TNS Social undertook a repeat of the 2003 Scottish Crime Survey as part of a study to estimate the impact of switching crime survey data collection to telephone interviewing. This involved collecting data on drug use from a random sample of Scottish adults. The data are not yet published and cannot be reported here but the estimates from the survey have been used as part of this exercise with the agreement of the SCVS project manager.
8. Respondents were only asked about driving after using drugs if they had reported using drugs. Any under-reporting of drug use would therefore have a direct impact on the measure of drug driving.

15. The authors of the UK part of the IMMORTAL study, which sought to relate accident risk to drug impairment concluded that while " …it was desirable in this study to set threshold levels for drugs, above which impairment is likely, and report the prevalence of drugs above these thresholds. Unfortunately, no accepted impairment thresholds exist for oral fluid - so for estimating and reporting drug prevalence in this study, it was decided to include only cases where drug levels equalled or exceeded the confirmatory test cut-off concentrations for oral fluid proposed by the Substance Abuse and Mental Health Services Administration ( SAMHSA). Cases that equal or exceed these SAMHSA levels indicate a positive drug usage but not necessarily impairment."
