PRIMARY STUDY
The Effects of β-myrcene on Simulated Driving and Divided Attention: A Double-Blind, Placebo-Controlled, Crossover Pilot Study
Key Findings: β-myrcene, thought to be the sedating terpene in cannabis, was associated with reduced speed control and increased errors on a simulated driving test, consistent with the hypothesis that β-myrcene impairs driving.
