Adolescent users of 3,4-methylenedioxymethamphetamine (MDMA, Ecstasy) may escalate their dose because of the development of tolerance. We examined the influence of intermittent adolescent MDMA exposure on the behavioral, physiological, and neurochemical responses to a subsequent MDMA "binge" or to a 5-hydroxytryptamine(1A) (5-HT1A) receptor challenge. Male Sprague-Dawley rats were given MDMA (10 mg/kg b.i.d.) or saline every 5th day on postnatal days (PDs) 35 to 60.
