These results provide further evidence that phenotypic differences between HR and LR may, in part, be associated with differences in the endogenous opioid systems. Differences in sensitivity to acute versus repeated morphine suggest that at least in relation to opioid drugs, these phenotypes may reflect different aspects of drug vulnerability rather than simply the presence or absence of it.
