Norepinephrine effec: You are on Adderall which increases norepinephrine. Nucynta (tapentadol) does not just work on morphine receptors, rather it is also a norepinephrine reuptake inhibitor. A relative high incidence of hallucinations has been reported, especially among patients on anti-depressants, possibly due to its pro-adrenergic properties. En.Wikipedia.Org/wiki/nucynta.
