Notes:
In the baboon study, doses of 0.32, 1.0, and 3.2 mg/kg/inj MDMA engendered responding at a rate greater than that maintained by saline, but less than that maintained by 0.32 mg/kg/inj cocaine (Lamb and Griffiths, 1987).
In the rhesus monkey study however, doses of 0.03 and 0.1 mg/kg/inj supported response rates greater than those maintained by 0.03 or 0.05 mg/kg/inj cocaine in some subjects (Beardsley et al., 1986).
