Time to complete the fine-motor task following administration of a GHB, b GBL, and c 1,4-BD. Data shown are group means (±1 standard error of the mean) for duration (seconds) to complete the fine-motor task at 30, 60, and 120 min postadministration of vehicle (V) or each drug dose (milligrams/kilogram). Data for GHB are replotted from Goodwin et al. (2005), and the task was completed only at 60 and 120 min postadministration of GHB. *p<0.05 represents significant interaction between a drug dose and vehicle at the same time (30, 60, or 120) as determined in pair-wise post hoc tests
