There is concern that combining energy drinks with alcohol may ‘mask’ subjective intoxication leading to greater alcohol consumption. This study examines the effects of alcohol alone and combined with energy drink on objective and subjective intoxication and mood over the course of 3 h. 

The effects of alcohol mixed with energy drink (AMED) on subjective intoxication and alertness: results from a double‐blind placebo‐controlled clinical trial

The purpose of this double blind placebo controlled study was to examine if specific effects on subjective intoxication and alertness–sleepiness ratings could be demonstrated after consuming alcohol

Alcohol mixed with energy drink (AMED): A critical review and meta‐analysis

This systematic review and meta‐analysis critically review the prevalence of alcohol mixed with energy drink (AMED) consumption and whether AMED consumption has an impact on alcohol consumption, subjective intoxication, and risk‐taking behavior.

Energy drinks mixed with alcohol: are there any risks?

While some publications conclude that consumption of energy drinks mixed with alcohol is problematic, others do not support these claims and point out the methodological shortcomings of many studies in this area.

Attentional and working memory performance following alcohol and energy drink: A randomised, double-blind, placebo-controlled, factorial design laboratory study

Mutual antagonism between alcohol and ED showed no consistent pattern and likely reflects a complex interaction between caffeine and alcohol levels, phase of the blood alcohol limb, task domain and cognitive load.

Alcohol metabolism in hangover sensitive versus hangover resistant social drinkers

It is suggested that drinkers who usually experience hangovers after a heavy drinking occasion do not experience alcohol intoxication more than hangover resistant drinkers.



The effects of energy drinks alone and with alcohol on neuropsychological functioning

Caffeinated energy drinks—alone or with alcohol—are heavily marketed to young adults, many of whom believe that caffeine counteracts some negative effects of alcohol intoxication, and few studies have examined neuropsychological performance after consumption of a beverage containing both ingredients.

The effects of energy drink in combination with alcohol on performance and subjective awareness

Subjective effects reflected awareness of alcohol intoxication and sensitivity to increasing alcohol dose and no evidence that the energy drink masked the subjective effects of alcohol at either dose was found.

Effects of alcohol mixed with energy drink and alcohol alone on subjective intoxication

This within-subjects study does not confirm the presence of a “masking effect” when combining caffeine or energy drink with alcohol.

The impact of alcohol and energy drink consumption on intoxication and risk-taking behavior.

The interactive effect of AmED appears restricted to perceived stimulation, with alcohol-induced increases in subjective intoxication occurring regardless of presence or absence of ED.

Effects of energy drinks mixed with alcohol on information processing, motor coordination and subjective reports of intoxication.

AmED may contribute to a high-risk scenario for a drinker because the mix of behavioral impairment with reduced fatigue and enhanced stimulation may lead AmED consumers to erroneously perceive themselves as better able to function than is actually the case.

Effects of energy drink ingestion on alcohol intoxication.

The ingestion of alcohol plus energy drink significantly reduced subjects' perception of headache, weakness, dry mouth, and impairment of motor coordination, however, the ingestion of the energy drink did not significantly reduce the deficits caused by alcohol on objective motor coordination and visual reaction time.

Effects of caffeine on alcohol-related changes in behavioural control and perceived intoxication in light caffeine consumers

Caffeine appears to have mixed effects on alcohol intoxication that are task-dependent, and increased stimulation in the alcohol/caffeine condition is found, supporting the contention that caffeinated alcoholic beverages enable an individual to drink for longer.

Neurocognitive and mood effects of alcohol in a naturalistic setting

The current pilot study aimed to assess the effects of drinking alcohol in a naturalistic setting on aspects of performance.

Cognitive and physiological effects of an “energy drink”: an evaluation of the whole drink and of glucose, caffeine and herbal flavouring fractions

There is some degree of synergy between the cognition-modulating effects of glucose and caffeine which merits further investigation, and the whole drink resulted in significantly improved performance on “secondary memory” and “speed of attention” factors.

Energy drinks mixed with alcohol: misconceptions, myths, and facts

Although some reports suggest that energy drinks lead to reduced awareness of intoxication and increased alcohol consumption, a review of the available literature shows that these views are not supported by direct or reliable scientific evidence.
