Effects of cannabidiol on simulated driving and cognitive performance A dose-ranging randomised controlled trial.
Cannabidiol (CBD), a major cannabinoid of We investigated the effects of CBD on driving performance. Healthy adults ( Non-inferiority was established during the standard component of Drive 1 and CF component of Drive 2 on all CBD treatments and during the standard component of Drive 2 on the 15 and 1500 mg treatments (95% CIs < 0.5). The remaining comparisons to placebo were inconclusive (the 95% CIs included 0 and 0.50). No dose of CBD impaired cognition or induced feelings of intoxication ( Acute, oral CBD treatment does not appear to induce feelings of intoxication and is unlikely to impair cognitive function or driving performance (Registration ACTRN12619001552178).
