Background: Mixing alcohol with energy drinks (AmED use) has been purported to increase riskybehavior and alcohol consumption. The current study applied a within-subject retrospective selfreport design to examine the association between AmED use (versus alcohol-only) and risky behavior,alcohol consumption and motivations. Method: New Zealand alcohol consumers aged 18–35 years(n = 289; AmED users: n = 143) completed an online survey. Results: Compared to alcohol-only, AmEDuse was associated with significant reductions in nine of twenty-six risk taking behaviors. The averageamount of alcohol consumed did not differ between sessions. Maximum alcohol intake was greater inalcohol-only sessions than in AmED sessions. Motivations for consuming AmEDs and beliefs on theireffects were not related to differences in typical alcohol intake in either session. The motivation to drinkAmED “for the thrill” was associated with a higher general risk-taking propensity score, but notmotivations and beliefs relating to being in control and feeling less drunk. AmED users did not havea significantly higher general risk-taking propensity than non-users. Conclusions: use does notappear to increase risk-taking behavior or alcohol consumption and is associated with decreased risktaking behavior and binge drinking.
