The Effects of Cannabidiol on the Driving Ability of Healthy Adults
Condition: Driving Performance; Cognitive Impairment; Sedation Complication; Mood
MeSH terms: Cognitive Dysfunction
Study type: Interventional
Phase: Phase 2

Summary: 
      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.
    


Intervention name(s): 300 mg Cannabidiol (CBD) oil; Placebo
Intervention type(s): Drug; Drug
Intervention description(s): Participant will either be given a 300mg dosage of CBD oil. After consumption of the study drug, the participant will wait for 120 minutes to allow for digestion and for CBD to begin taking effect. Next, individuals will undergo a driving simulation and all participants will drive the same course. The simulator presents the individual with real life driving scenarios and is equipped with screens, a steering wheel, signals, and pedals. The participant will be instructed to drive the course for 25-35 minutes. They will be instructed to follow normal driving rules. The simulation will include highway, suburban, rural, and urban driving scenarios which will incorporate turns, changes in speed, and avoidance of cars/pedestrians.; Participant will either be given a placebo .
