The Effects of Cannabidiol on the Driving Ability of Healthy Adults
NCT04590495 · View on ClinicalTrials.gov ↗
Study 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.

Full Details on ClinicalTrials.gov ↗What the Registry Record Tells You About NCT04590495
The ClinicalTrials.gov registry entry for NCT04590495 describes a study currently listed as completed. It is categorized as Phase 2, which is the standard way researchers label where a study sits along the investigational pathway from early safety work through later efficacy and post-marketing evaluation. The registered enrollment target is 40 participants, a figure that helps gauge the scale of data the investigators plan to collect. The listed sponsor is West Virginia University, which has 93 total studies on file at ClinicalTrials.gov, and sponsors are the parties responsible for study design, oversight, and regulatory filings.
The record links to 4 conditions, with Cognitive Impairment appearing as the primary indexed condition, and to 2 interventions — of which Placebo is the first listed. Interventions can include drugs, devices, procedures, behavioral programs, or observational arms, and each is tracked as a separate registry field so that downstream queries can filter accurately. When a trial lists multiple interventions, it usually reflects a multi-arm design or a comparison protocol rather than a single treatment being tested in isolation. The brief summary published in the registry is the clearest source of protocol intent and should be read before drawing conclusions from any sidebar tags.
Geographic footprint matters for practical reasons: NCT04590495 reports 1 study location spanning 1 distinct geographic area — top geographies include West Virginia. A larger site network tends to correlate with broader recruitment capacity, but it does not imply anything about study quality, and site-level enrollment status can diverge from the overall registry status shown above. Every data point on this page comes from the public ClinicalTrials.gov dataset and is reproduced here for reference only; it is not a medical recommendation, an endorsement of the sponsor, or an invitation to enroll.
