Finally, we did not have biological measures or (related to the above) measures of drinking context. Though racial/ethnic disparities in dependence were nonsignificant following PS weighting, it remains possible that biological differences contribute to disparities in reactivity to alcohol, and hence dependence. Indeed, the striking differences between Black and White men in reported physiological effects of alcohol use, detailed in Table 2, underline the importance of exploring biological contributors to Black-White disparities, particularly since these differences were found among those reporting little or no heavy drinking.
