This research examines MDMA effects on driving related task performance, including psychomotor function (such as tracking, movement speed), cognitive function (attention, executive function and planning) and object movement prediction. In addition, mood changes and physiological measures were assessed, and MDMA levels were measured in blood, sweat, urine and saliva. Studies already published were conducted according to a placebo-controlled, cross-over, double-blind design and treatments included placebo, 75 mg MDMA and 0.5 g/kg alcohol.
