title: The influence of alcohol and tobacco on the components of choice reaction time.
abstract: In smokers a low dose of alcohol slightly improved decision time on a choice reaction-time task and in combination with tobacco resulted in significant improvement compared with placebo conditions. In nonsmokers decision time deteriorated significantly after a moderate dose of alcohol but not in smokers. The results are attributed to the stimulant action of a smoking dose of nicotine interacting with low levels of alcohol.
