This  study  examined  the  psychophysiological  effects  of  coffee  consumption  on  anxiety  as  reported  by  University students.  .  It  was  hypothesized  that  heavy  caffeine  users  would  report  significantly  higher  anxiety  and  more psychophysical symptoms of caffenism more than non-users. A sample size of 447-university students made up of 239 males and 208 females within ages 16-36 years (M = 22.7; SD = 2.92) participated in the study. All respondents completed an adapted version of STAI forms Y-1 and Y-2 which measures state-trait anxiety. Analysis of data revealed significant difference between coffee users and non -users on state  anxiety.  The  quantity  and  frequency  of  daily  coffee  consumption  were  found  to  be  related  to  the  symptoms exhibited on state anxiety. There was no significant sex difference on the frequency and quantity of coffee consumption but a significant age difference in favour of younger respondents was recorded on frequency of coffee consumption. Various symptoms reported by the respondents confirmed  the stimulating properties of caffeine.  It is recommended that awareness and enlightenment programmes on effects of consumption on human psychophysiological responses be created by government and other stakeholders
