In addition, the combination of both drugs did not increase how impaired drivers were.

The data showed that the more often an individual engaged in drug use with these three drugs, the more likely they were to have driven under the influence of them. A significant factor associated with drugged driving was the low perception of causing an accident. The findings in this study can be used to more specifically target intervention methods at chronic users and drugged drivers.

They also determine that driving drugged has a potentially greater risk of getting into an accident than driving drunk.

Specifically, individuals under the influence of dexamphetamine were less likely to signal when changing lanes or at intersections, and less likely to stop at red lights. These results are consistent with the author’s finding of reduced visual acuity for those under the influence.

Drummer. “Does Related Risk of Motor Vehicle Crashes After Cannabis Use.” 73 Drug and Alcohol Dependence (2004): 109-119. – The authors find that the detrimental effects of THC appear more prominent in highly automated driving behavior, such as road tracking control, as compared to complex driving tasks that require conscious control. Drivers involved in crashes who tested positive for THC were found to be about three to seven times more likely to be responsible for their crash as compared to drivers who had not used drugs or alcohol.

Langley and Shaun Stephenson. “Identifying Factors that Predict Persistent Driving after Drinking, Unsafe Driving after Drinking, and Driving after Using Cannabis among Young Adults.” 35 Accident Analysis & Prevention 5 (September 2003): 669-675. – The goal of this article was to determine the factors that predicted three different scenarios among young adults: persistent driving after drinking, persistent unsafe driving after drinking and persistent cannabis use and driving. The data from a longitudinal study concluded that different factors lead men and women to engage in these activities, and therefore different intervention programs need to be designed with these characteristics in mind.

The data shows that drugged drivers had higher rates of being arrested again. Specifically prior-arrests, being male and being younger than 36 were significant and influential factors in determining rearrest rates.
