Driving under the influence of cannabis and alcohol: Evidence from a national sample of young drivers

Ethanol blood analysis is the most common request in forensic toxicology, and some studies point to positive results in approximately one-third of all unnatural deaths. However, distinguishing sober deaths from drunk deaths is not as simple as it may seem. This technical, clinical, and forensic interpretation is proposed to interpret the ethanol toxicological results, discussing several artifacts and pitfalls that must be considered, namely focusing on driving under the influence. This work is presented with a practical and objective approach, aiming to alleviate the complexities associated with clinical, physiological, pathophysiological, and toxicological aspects to enhance comprehension, practicality, and applicability of its content, especially to courts. Particularly the physical integrity of the body, the postmortem interval, putrefactive signs, anatomic place of blood collection, alternative samples such as vitreous humor and urine, the possibility of postmortem redistribution, the inclusion of preservatives in containers, and optimal temperature conditions of shipment are among some of the aspects to pay attention. Although the proposal of several biomarkers of postmortem microbial ethanol production, their translation to forensic routine delays is limited due to current uncertainties and analytical constraints that render their application. Specifically, in the interpretation of ethanol toxicological results, ‘not everything that can be counted counts and not everything that counts can be counted’ (attributed to Albert Einstein).
