AED Effects on Subjective Feelings of Intoxication
In laboratory studies with human subjects, caffeine:
- Reduced volunteers’ subjective feelings of alcohol intoxication when compared to those who drank similar quantities of alcohol without caffeine
- Did not reduce alcohol’s destructive impact on volunteers’ heart rate, oxygen intake, and other physiological variables during strenuous exercise;
- Adversely affected volunteers’ visual reaction time, motor coordination, and other physical skills.

In laboratory studies using rats:
- Alcohol made the animals more relaxed, but less able to avoid unpleasant shocks and navigate a maze
- Caffeine improved the animals ability to navigate the maze and avoid the shocks
- Alcohol combined with caffeine made the rats relatively alert and relaxed, but they were incompetent to avoid unpleasant shocks and navigate a maze as those receiving alcohol and no caffeine.
