Cannabis use is frequently detected in motor vehicle crashes. While research has found an increased crash risk of driving under the influence of cannabis, research on the effects of cannabis, or THC, on driving behaviour seems to be somewhat limited to vehicle control. Our objectives were to map available research into the effects of THC on higher-order driving skills during actual driving. A...

Objective: Driver distraction contributes to fatal and injury crashes in young drivers. Mind wandering (MW) is a covert form of distraction involving task-unrelated thoughts. Brief online mindfulness training (MT) may reduce unsafe driving by enhancing recognition (meta-awareness) of MW and reducing its occurrence. This pilot trial tested these proposed mechanisms of MT and explored its...

Many classify these drugs as "Light" drugs and therefore allow themselves to drive after consuming them. The study had two main objectives: 1) to investigate the effect of alcohol (BAC=0.05%), THC (13 mg) and their combination on...

The effects of marijuana or THC on driving has been tested in several studies, but usually not in conjunction with physiological and subjective responses and not in comparison to alcohol effects on all three types of measures. To assess the effects of two dosages of THC relative to alcohol on driving performance, physiological strain, and subjective feelings. We tested the subjective feelings...

A review was performed of the marihuana and driving literature, both epidemiological and experimental. It was noted that epidemiological studies face considerable difficulties in obtaining estimates of risks involved for drivers utilizing marihuana due to the rapid decline in blood levels of tetrahydrocannabinol. On the other hand, experimental studies examining the relationship between...
