Visual analog subscale positive subjective drug effects of “Stimulated; “High”; “Good”; and “Any effect” (0 – 12.5 hours): Racemic MR-dl-MPH (40 mg) was administered alone (□) or followed by ethanol (0.6 g/kg) 4–4.25 hours later (▪). Enantiopure MR-d-MPH (20 mg) was administered alone (Δ) or followed by ethanol (0.6 g/kg) 4–4.25 hours later (■). MPH administration was at T = 0 hours. Effect ratings were from 0 = “Not at all” to 100 = “Extremely”; Values represent the arithmetic mean (+/− SD); *P < 0.05; **P < 0.01; aP = 0.071; bP = 0.078.
