Official title
The Effects of Cannabidiol on the Driving Ability of Healthy Adults: a Clinical Trial
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
A randomized, parallel-group, double-blind, exploratory two-arm trial to assess the effects of CBD on driving ability along with changes in psychological status (i.e. mood, drowsiness, sedation) and cognitive function. Forty healthy West Virginia University (WVU) students will be allocated and randomized to receive: (1) 300 mg of pure CBD oil or (N=20) (2) placebo matched in appearance and taste (N=20). After consuming the study drug, each individual will participate in a 25-35-minute driving simulation and their driving performance measured. To assess changes in psychological status (i.e. mood, drowsiness, sedation) and drug impairment-related cognitive function, the Visual Analog Mood Scale, Stanford Sleepiness Scale , Digital Symbol Substitution Test, Trail Making Test Part A and B, Psychomotor Vigilance Test, and Simple Reaction Time test will also be administered to participants at baseline (prior to study drug consumption) and following completion of the driving simulation test. The entire protocol will be completed in one day and should take 4-4.5 hours to complete for each participant.
