^aBefore and after each experimental session, subjects had to rate their current mood on a 17 item questionnaire. Each item consisted of a VAS with opposing verbal descriptors at each end. Ratings were scored from 0 to 10. Data are the average group scores (mean ± SEM). SC, Saline control group; OS, opioid suspension group; T1, before Session 1; T2, after Session 1; T3, before Session 2; T4, after Session 2.
