F 10 g/70kg, then the drug comparison dose of GHB would be eight g/70kg. If a participant tolerated the maximum dose of a drug (e.g., 10 g/70 kg GHB or 120 g/70 kg ethanol) with out attaining a stopping point then that dose will be defined because the maximum tolerated dose for comparison. Outcome Measures Four forms of outcome measures had been assessed: participantrated, observerrated, motor/ cognitive, and physiological. On drug sessions days measures were assessed just before drug administration and 0.5, 1, two, 3, four, six, 8, 12 and 24 h right after drug administration, except where noted under for certain measures. Assessment instances are relative for the starting of drug administration, even in situations with longer administration duration. In order to give participants practical experience with these tasks, practice trials had been provided prior to the very first session. Unless otherwise stated, questionnaires regarding participantrated and observerrated measures had been administered on a desktop pc. The participant or staff member made use of a computer mouse to point to and choose one of the several response possibilities displayed around the screen.
