The Effect of Cannabidiol (CBD) on Simulated Car Driving Performance: A Dose-Ranging Study of Healthy Volunteers.
While research has shown that cannabis, and its major intoxicating ingredient – THC, impair car driving performance, the influence of cannabidiol (CBD) (alone) has not been studied. Findings from several investigations suggest that, unlike THC, CBD is non-intoxicating and does not impair cognitive function. However, given the potential harms associated with road traffic accidents and the increasing use of CBD (among both clinical and non-clinical populations) research clarifying its effect on driving performance is warranted. This study will investigate the effect of acute, oral CBD treatment (at three different doses) on simulated driving performance using a crossover design.
