PRIMARY outcome

Timeframe: 8 hours

Computerized version of Paced Auditory Serial Addition Task will be administered to assess working memory performance. Reported data reflect the peak change from baseline in the total correct trials out of 90 recorded (lower scores indicate worse performance) obtained 1, 2, 3, 4, 6, or 8 hours post-dose.

PRIMARY outcome

Timeframe: 8 hours

Cognitive performance will be evaluated with the Divided Attention Task. Reported data reflect the peak change from baseline performance measured as the mean distance (in computer pixels) of the mouse cursor from the central stimulus recorded 1, 2, 3, 4, 6, or 8 hours post-dose. Higher scores indicate worse performance.

PRIMARY outcome

Timeframe: 24 hours

The DEQ will be used to obtain subjective ratings of "feel drug effects". Score range from 0 (none) to 100 (extreme) using a 100mm line anchored with none/extreme designation. Peak rating within 24 hours post-dose is reported.
