Summary
Subjects will participate in a 4-visit study protocol at the National Advanced Driving
Simulator, part of the University of Iowa, in which they will be asked to complete assorted
questionnaires, computerized cognitive tasks, and a simulator drive. Subjects will be
administered 0.75 mg alprazolam (Xanax) or placebo and 500 mg vaporized cannabis (6.18% THC /
<0.025% CBD) or placebo (0% THC / 0% CBD).
The primary objective of this study is to validate the Drug Impaired Driving Scenario (DIDS)
using the CRCDS-2 driving simulator by assessing the acute effects of cannabis relative to
placebo on simulated driving performance. Assay sensitivity will be demonstrated by the
significant effect of 0.75 mg alprazolam (active comparator) on driving and cognitive
endpoints.
