James (2005) misrepresented and misinterpreted several aspects of the report by Lyvers, Brooks, and Matica (2004) on cognitive and psychophysiological effects of caffeine. Lyvers et al. did not claim that an alcohol breath test is a test of caffeine levels. The apparent enhancement effect of caffeine on neuropsychological performance, obtained in light users but not heavy users, was unlikely to be accounted for by reversal of withdrawal-induced deficits.
