LOPERA VALLE, Johan Sebastián  y  ROJAS JIMENEZ, Sara. Cannabinoids: a cognitive obstacle to drive safely. Acta toxicol. argent. [online]. 2014, vol.22, n.1, pp.23-32. ISSN 1851-3743.

The high economic and human losses that bring traffic accidents, as well as their social and political implications, make evident the need of a clear understanding of all the factors that influence its incidence and severity, between which states the use of psychotropic drugs as cannabis. After two decades of substantial reductions in the magnitude of the problem of alcohol consumption and traffic accidents, the widespread use of cannabis in the world is what makes it, after alcohol, the psychoactive substance most commonly found in the blood of drivers involved in such accidents; the presence of cannabis is associated with twice the risk of being fatally injured in traffic. Contrary to popular belief, marijuana should not be considered a benign drug, its use is associated with cardiovascular, pulmonary, reproductive, immunological, and especially with locomotor and cognitive disorders; blood tetrahydrocannabinol concentrations of 2-5 ng/mL are associated with substantial deterioration in the skills needed to operate a motor vehicle. Therefore, further investigations are required to establish clear causal links, to favor the generation of long-term public policy of vial responsibility, to divulge the devastating human, social and economic impacts that are generated because of the act of consuming cannabis while operating a motor vehicle on the track.
