| Trial ID | NCT02709954 |
| Phase | N/A |
| Status | Active Not Recruiting |
| Condition | Cannabis |
| Intervention | Active inhaled delta-9-THC |
With increasing cannabis legalization and concurrent alcohol use, understanding the combined cognitive and psychomotor effects of these substances on driving performance addresses a critical public safety gap. This research provides essential data for evidence-based impairment detection and policy development.
This active observational study examines the effects of inhaled delta-9-THC, ethanol, and their combination on simulated driving performance and cognitive function. The trial uses controlled administration of both substances to measure impairment patterns, reaction times, and driving simulator metrics. Currently active but not recruiting, this study aims to establish pharmacokinetic-pharmacodynamic relationships between substance levels and measurable impairment.
