Cannabis effects on driving skills

In this article, the authors review the current literature on the effect of cannabis on driving, with a focus on epidemiological and experimental data. Experimental data show that cannabis smoking increases risk of motor vehicle accidents two-fold. It also shows, while that drivers attempt to compensate more slowly after smoking cannabis, control deteriorates with increasing task complexity. Lane weaving and impaired cognitive function are also found to increase, and cannabis smoking can impact critical tracking tasks, reaction times, divided attention tasks and lane position variability. The authors' suggest that future research on the effect of cannabis on driving should emphasize challenging tasks and include occasional and chronic daily cannabis smokers.
