The panel was required to consider drugs listed in the Misuse of Drugs Act (1971) and to make recommendations with regard to which controlled drugs should be specified in the subsequent drug driving regulations (Crime and Courts Bill), and to advise what an appropriate limit for each of those drugs might be. The focus on &#8220;psychoactive&#8221; drugs meant that the panel excluded the drugs in schedule 4 part 2 (anabolic steroids) from consideration. This is the first report to pull together in a critical manner the current scientific evidence concerning drug driving and road collision risk contextualised with data from English drivers.<!--more--><\/p>\n<p>To address some specific inaccuracies in Sare\u2019s blog:\u00a0 The final list of 14 drugs was based on careful evaluation of a wide range of material in addition to the prevalence data reported in the CSEW [1]. For instance, although the prevalence data for cocaine and mephedrone are similar, the evidence base for these drugs is significantly different. We found over 230 peer reviewed articles that had investigated cocaine and driving and no such publications for mephedrone. Consequently, we know a great deal about patterns of use concerning cocaine. Its acute effects and &#8220;come down&#8221; are well described in relation to the deleterious effects on driving behaviour. This is simply not the case for mephedrone, as yet.<\/p>\n<p>Two papers have been published concerning mephedrone since the completion of the report: Crosbey et al, 2013, and Marinetti and Antonides (2013) [2,3]: the latter of who report that blood concentrations of synthetic cathinones do not appear to predict outcome regarding driving fatalities or impairment.<\/p>\n<p>Secondly, crystal meth (methamphetamine) is actually well established as a recreational drug in this country. It has been identified in central London, from the analysis of anonymous pooled urine from portable urinals [4], and regionally using the sewage epidemiology approach to estimate community based drug consumption (from the River Avon and sewage effluent in Somerset to wastewater treatment plants in Yorkshire) (Bagnall et al, 2012; Kasprzyk-Hordern B, Baker DR, 2012 [5,6]). The panel was satisfied that methamphetamine is currently used across the UK and that there was sufficient evidence with regard to road safety risk to recommend thresholds.<\/p>\n<p>Thirdly, the panel did not make threshold recommendations based on different drug classifications. This was clearly explained in the report. We looked specifically at risk: risk of an injurious or fatal road traffic collision (RTC) in drug drivers compared to non drug drivers.\u00a0 Blood drug concentrations are themselves individually specific, a reflection of the physicochemical properties of the substance, pharmacokinetics, dosage, formulation, and route of administration. In our report the thresholds were exclusive to each drug and we took particular note of the concentrations observed in drug drivers.<\/p>\n<p>The panel\u2019s recommendations are for confirmatory tests to be undertaken in the police station and not in relation to road-side screening by type approved devices. This work is ongoing and is a separate vein of work.<\/p>\n<p>A further point is that the confusion over the period of time that cannabis can be determined in the body relates to the identification of cannabis metabolites in urine. Our recommendation refers only to THC (delta-9-tetrahydro cannabinol or \u03949- tetrahydrocannabinol) the main psychoactive constituent of cannabis in blood. We have recommended a threshold above which it is considered that the risk to road safety is unacceptably high. The threshold is higher than average concentrations observed in those prescribed the drug.<\/p>\n<p>It is important that the expert panel report is not seen as a <em>fait accompli<\/em>. The panel has endorsed the development of a five year drug driving strategy as recommended by the House of Commons\u2019 Transport Committee (2010) in its inquiry into drink and drugs driving law. The panel has also suggested that any strategy should encompass an ongoing review of drug driving behaviours and any drug thresholds to be set.<\/p>\n<p>Indeed, the new legislation is such that the \u201clist\u201d can be expanded as dictated by the scientific evidence as it becomes available. The popular drugs that Sare mentions (LSD, GBL, or psilocybin) were addressed in the panel report. We recommended keeping a watchful brief. To date, LSD, GBL, and psilocybin have not been detected in drivers apprehended for drug driving or involvement in road traffic collisions in this country.<\/p>\n<p>We are really only at the beginning.<\/p>\n<p><em><strong>Kim Wolff<\/strong>, chair expert drug driving report, King\u2019s College London.<\/em><\/p>\n<p><em>I declare that that I have read and understood the BMJ Group policy on declaration of interests and I hereby declare that as chair of the drug driving panel I received an honorarium for this work and have no additional conflicting interests<\/em><\/p>\n<p>References:<\/p>\n<p>1.\u00a0\u00a0 \u00a0CSEW : Crime Survey for England and Wales<br \/>\n2.\u00a0\u00a0 \u00a0Cosbey SH, Peters KL, Quinn A, Bentley A.
