The Effects of β-myrcene on Simulated Driving and Divided Attention: A Double-Blind, Placebo-Controlled, Crossover Pilot Study

Abstract Background.: β-myrcene, one of the most common terpenes found in cannabis, has been associated with sedation. We propose that β-myrcene contributes to driving impairment even in the absence of cannabinoids. Aim.: To conduct a double-blind, placebo-controlled crossover pilot study of the effect of β- myrcene on performance on a driving simulator. Method.: A small sample (n=10) of participants attended two experimental sessions, one in which they were randomized to receive 15 mg of pure β-myrcene in a capsule versus
