In the present study, DMAA produced locomotor depression, fully substituted for the discriminative stimulus effects of cocaine, produced partial substitution for methamphetamine (77% drug-appropriate responding), and produced a conditioned place preference. The potency of DMAA was comparable in all three assays (between 2.3–3.3 mg/kg). These results indicate that DMAA produces reward-like effects and may produce subjective effects similar to that of abused psychostimulants, and therefore has potential for abuse.
