Consumption of a prominent synthetic cathinone known as mephedrone (4-methylmethcathinone) has become a popular alternative to club drugs such as ecstasy, cocaine, and methamphetamine within the past decade. The pharmacological mechanisms that contribute to its subjective effects have yet to be fully characterized and are thus warranted for investigation. The present study employed drug discrimination methods to train eight male Sprague-Dawley rats to discriminate injections of 3.0 mg/kg mephedrone from saline. Various doses of mephedrone, 3,4-methylenedioxypyrovalerone (MDPV), d-amphetamine (AMPH), cocaine, (+)-methamphetamine (METH), and 3,4-methylenedioxy-methamphetamine (MDMA) were investigated for their ability to substitute for the stimulus cues of the training …
