Registered outcomes7
Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Road Tracking Error | baseline, +20, +50, +120, +180 mins after start of alcohol and THC infusion | changes in road tracking errors between timepoints to assess the effects of alcohol and THC on road tracking errors. |
| Secondary | Biphasic Alcohol Effects Scale (BAES) | baseline, +20, +50, +120, +180, +240 mins after start of alcohol and THC infusion | A scale designed to assess the stimulant and sedative effects associated with alcohol intoxication. |
| Secondary | Visual Analog Scale (VAS) | baseline, +20, +50, +120, +180 mins after start of alcohol and THC infusion | Feeling states associated with alcohol and cannabis intoxication will be measured using this self-report scale of feeling states. |
| Secondary | Cognitive Test Battery | +40 mins after start of alcohol and THC infusion | Several computer tasks will be administered to assess alcohol and THC effects on driving related cognition, including: visual vigilance, visual motor function, attention and working memory, and processing speed. |
| Secondary | Willingness to Drive Scale | baseline, +20, +50, +120, +180 mins after start of alcohol and THC infusion | Subjects will be asked to rate their willingness to drive at their current state in the context of various scenarios including willingness to drive from testing facility to a number of destinations that are different driving distances. |
| Secondary | Number of Joints Scale | baseline, +20, +50, +120, +180 mins after start of alcohol and THC infusion | Subjects will be asked to rate the number of standard joints that they believe they have been administered. |
| Secondary | Number of Drinks Scale | baseline, +20, +50, +120, +180 mins after start of alcohol and THC infusion | Subjects will be asked to rate the number of standard drinks that they believe they have been administered. |
