Mean (±S.E.M.) responses for ethanol during 30 minutes sessions in nondependent and ethanol-dependent animals following 0.0 and 1.5 mg/kg prazosin. Prazosin (1.5 mg/kg) attenuated ethanol self-administration in ethanol-dependent animals (*** p<0.001), leaving nondependent self-administration intact.
