Who could benefit from this research
✓Could help
Healthy adults aged 18-30 who meet study criteria and consent to driving-simulation testing and CBD administration.
✕Less likely to help
Individuals outside the age range or with medical conditions affecting driving may not benefit from this research.
What this research studies
This project will recruit healthy adults aged 18-30 and test driving performance using a simulator after giving them different CBD doses. Participants will also complete self-report scales and cognitive tests to measure drowsiness and alertness. The study uses a 3-arm design to compare CBD doses and examine effects by biological sex, with safety monitoring and aftercare as needed. The researchers aim to better understand whether non-prescription CBD could affect real-world driving and safety for young adults.
Why it matters
Potential benefit: If CBD shows minimal impact on driving, it could reassure consumers about safety; if there is an effect, it could inform guidelines and education for drivers.
How similar studies have gone: Previous studies are few and have limitations, so this project seeks to provide clearer evidence.
