According to the Centers for Disease Control and Prevention, people who mix alcohol with energy drinks are four times more likely to binge drink compared to those who don't. So, what are alcoholic energy drinks and why is this deceptive combination so hazardous to your health and nutrition?

Quick Summary

Premixed caffeinated alcoholic beverages were banned due to severe public health concerns. The stimulant caffeine masks the depressant effects of alcohol, leading to a false sense of sobriety. This dangerous mix encourages overconsumption and is linked to risky behavior and significant health issues.

Key Points

Deceptive Combination: Caffeine in alcoholic energy drinks masks the sedative effects of alcohol, creating a false sense of sobriety and encouraging higher consumption.
Significant Health Risks: Mixing alcohol and caffeine is linked to serious health problems, including heart palpitations, elevated blood pressure, severe dehydration, and a higher risk of alcohol poisoning.
Increased Binge Drinking: Studies show that people who consume alcoholic energy drinks are significantly more likely to engage in high-risk binge drinking behaviors.
Banned Premixed Products: Due to numerous safety incidents, the FDA banned the sale of prepackaged alcoholic energy drinks containing added caffeine in the U.S. in 2010.
Nutritionally Unhealthy: These beverages are typically loaded with high levels of sugar and calories, offer no nutritional value, and contribute to weight gain and diabetes risk.
Dangerous Behavioral Outcomes: The masked intoxication leads to poor judgment and an increased likelihood of risky behaviors, including drunk driving, engaging in fights, and unsafe sex.

What Defines an Alcoholic Energy Drink?

An alcoholic energy drink (AED) is a beverage that combines alcohol with stimulants like caffeine and other ingredients typically found in non-alcoholic energy drinks. Although prepackaged AEDs were banned by the U.S. Food and Drug Administration (FDA) in 2010, individuals still mix energy drinks and alcohol, a practice particularly prevalent among younger adults.

The Primary Ingredients

Alcohol (Ethanol): A central nervous system depressant.
Caffeine: A central nervous system stimulant.
Taurine: An amino acid.
Guarana: A plant-based caffeine source.
High Sugar Content: Contributes calories but lacks nutritional value.

Nutritional Breakdown

Alcoholic energy drinks offer poor nutritional value, being high in sugar and calories, which can lead to weight gain and increase the risk of type 2 diabetes. Alcohol itself is calorie-dense. Combined with the sugar in energy drinks, the calorie count is significant; a large can of a former AED could have calories comparable to multiple cheeseburgers.

The Dangerous Effects of Mixing Stimulants and Depressants

The main danger of AEDs comes from combining a depressant (alcohol) and a stimulant (caffeine). Caffeine can hide the signs of alcohol intoxication, creating a state known as “wide-awake drunkenness,” where a person feels alert despite impaired judgment and motor skills. The combination can strain the cardiovascular system, potentially causing increased heart rate and blood pressure, and contribute to dehydration. Masked intoxication can lead to excessive drinking, raising the risk of alcohol poisoning. The mix can also disrupt sleep patterns. Impaired judgment from AEDs is linked to higher rates of risky behaviors.

Why Were Premixed Alcoholic Energy Drinks Banned?

In 2010, the FDA determined that adding caffeine to alcoholic beverages was an “unsafe food additive”. This decision followed reports of hospitalizations, particularly among college students consuming drinks like Four Loko and Sparks. The ban addressed the public safety risk caused by masking the effects of alcohol. Although premixed drinks are banned, mixing alcohol and energy drinks is still risky and discouraged.

Comparison Table: Alcoholic Energy Drinks vs. Alcohol vs. Energy Drinks


Feature	Alcoholic Energy Drinks (AEDs)	Standard Alcoholic Beverages	Standard Energy Drinks
Main Effect	Stimulant masks depressant effect	Depressant (slows down the CNS)	Stimulant (increases alertness)
Key Ingredients	Alcohol, caffeine, sugar, taurine	Alcohol, water, various flavors	Caffeine, sugar, taurine, vitamins
Intoxication Perception	Decreased awareness of impairment	Increases with consumption	N/A
Risk of Overconsumption	Very high, due to masked impairment	Moderate, signs of intoxication are felt	Limited by stimulant side effects
Cardiovascular Impact	High risk (irregular heartbeat, high BP)	Moderate risk (high BP)	Moderate risk (high BP, palpitations)
Nutritional Profile	High calories, high sugar, empty nutrients	High calories, empty nutrients	High calories, high sugar, empty nutrients

Safer Alternatives and Informed Choices

For those seeking increased energy, healthier options are available. Coffee offers caffeine without alcohol's effects. Staying hydrated with water and eating nutritious foods are sustainable ways to maintain energy. If you choose to drink alcohol, do so in moderation and avoid mixing it with stimulants. Health guidelines, such as those from the UK's Chief Medical Officers, recommend limiting weekly alcohol intake. Avoiding AEDs is vital for health. Individuals struggling with substance misuse should seek professional help.

Conclusion: The Final Word on What Are Alcoholic Energy Drinks

The analysis of what are alcoholic energy drinks highlights their deceptive and dangerous nature. By masking alcohol's effects, they promote excessive drinking, increasing the risk of binge drinking, alcohol poisoning, and reckless behavior. This combination also burdens the cardiovascular system and provides empty calories, hindering healthy dietary goals. The 2010 FDA ban on premixed products was a crucial safety measure, but the dangers persist when individuals mix these substances themselves. The best advice for health and nutrition is to avoid this combination entirely and make responsible choices about consumption.

Frequently Asked Questions

In the United States, premixed alcoholic energy drinks containing added caffeine were banned by the FDA in 2010 due to safety concerns. The ruling was a response to the deceptive nature of the drinks and the serious health risks they posed.

Mixing alcohol and caffeine is dangerous because the stimulant (caffeine) masks the depressant (alcohol) effects. Drinkers may feel more alert than they are, leading them to consume more alcohol, which increases the risk of alcohol poisoning, injuries, and other serious consequences.

While not illegal like the old premixed products, health experts strongly advise against self-mixing alcohol with energy drinks. The combination carries the same significant health risks as the banned premixed versions, including masked intoxication and heart strain.

The combination can lead to a range of health issues, including heart palpitations, elevated blood pressure, severe dehydration, sleep disturbances, anxiety, and increased risks of addiction, liver damage, and alcohol poisoning.

Masked intoxication impairs judgment and reduces inhibitions, which increases the likelihood of risky behaviors such as drunk driving, fighting, and engaging in unwanted or unprotected sexual activity.

Yes, these drinks are typically very high in calories and sugar. The combination of the alcohol's calories and the added sugar from the energy drink makes them nutritionally poor and can contribute to weight gain and diabetes risk.

There is no universally safe waiting period. Since caffeine has a half-life of about 5 hours, its stimulant effects can last for a long time. For maximum safety, health experts recommend waiting until the effects of one substance have fully worn off before consuming the other, or better yet, avoiding the combination entirely.
