Energy drink use, with or without alcohol, contributes to drunk driving

Highly caffeinated energy drinks (EDs) have been of concern to the public-health community for almost a decade. Many young people consume EDs with alcohol to decrease alcohol’s sedative effects and stay awake longer, enabling them to drink more alcohol. Adding to the growing body of research linking ED consumption with risk-taking and alcohol-related problems, this study examined its relationship with drunk driving. Importantly, the researchers differentiated between the different ways in which EDs are consumed: exclusively with alcohol, exclusively without alcohol, or both with and without alcohol depending on the occasion.
