Stoned drivers are as good at avoiding obstacles as their straight counterparts, a simulator study finds.
The reason, according to researchers from Hartford Hospital and the University of Iowa, is probably that potheads are slowpokes: they typically slow-down when they are high.
I am reminded by the results, published in the March Journal of Psychoactive Drugs, of a college buddy of mine who insisted that pot made him a better driver. It definitely made him less aggressive on the road.
