In a randomized, double-blind, placebo-controlled crossover trial, 14 healthy participants with a history of infrequent cannabis use smoked cannabis with 11% THC, 11% THC with 11% CBD, or placebo before a driving simulation.
When smoking cannabis, participants were less confident to drive but not more anxious when driving. Lateral position changes more frequently in the cannabis and THC groups, while there weren't statistically significant differences in headway. This was for the 5-minute car-following task, while there weren't any statistically significant differences for the highway and rural driving task.
