Norbinaltorphimine has weak and inconsistent effects on THC-induced taste avoidance in adolescent rats in that Norbinaltorphimine both attenuates and strengthens taste avoidance dependent on dose and trial. Norbinaltorphimine has limited impact on the final one-bottle avoidance and no effects on the two-bottle preference test. Interestingly, Norbinaltorphimine has no effect on THC-induced taste avoidance in adult rats as well[2]. Norbinaltorphimine pretreatment significantly attenuates stress-induced reinstatement of nicotine-CPP, but has no effect on nicotine-primed reinstatement[3].
