The 2010 Federal Ban on Caffeinated Alcoholic Beverages
In November 2010, the U.S. Food and Drug Administration (FDA) took a definitive stance on the production and sale of pre-mixed caffeinated alcoholic beverages (CABs). The agency issued warning letters to several manufacturers, stating that caffeine was an "unsafe food additive" for alcoholic malt beverages. This action effectively forced companies to reformulate their products or remove them from the market entirely, leading to a de facto federal ban. The decision was prompted by mounting public health concerns and reports of alcohol-related hospitalizations, particularly among college students.
Why Were They Banned? The "Wide-Awake Drunk" Effect
The primary danger of combining caffeine and alcohol is that the stimulating effects of caffeine can mask the sedative effects of alcohol. This creates a state known as "wide-awake drunkenness," where an individual feels more alert and less intoxicated than they actually are. The result is that people often drink more alcohol over a longer period, significantly increasing the risk of alcohol poisoning, impaired judgment, risky behavior, and accidents. Medical studies and real-world incidents provided clear evidence that this was a significant public health issue. The stimulant does not reduce blood alcohol concentration, it only makes the drinker less aware of their true level of intoxication.
A Look Back at Caffeinated Alcoholic Drinks (Before 2010)
Before the FDA crackdown, the market was flooded with several popular CAB brands. The most infamous of these was the original Four Loko, which was a potent blend of malt liquor, caffeine, taurine, and guarana. Other brands included Sparks, a beer that marketed itself with energizing ingredients, and Joose, which was known for its high alcohol content. These products were often sold in colorful cans, and some manufacturers were accused of marketing them to underage drinkers. The backlash and eventual ban forced these companies to remove the stimulants from their formulas.
Modern Alternatives: Hard Seltzers vs. Energy Drinks
In the post-ban market, companies have shifted their strategies. Instead of mixing caffeine and alcohol, they have launched two distinct product lines: standard energy drinks (no alcohol) and new, non-caffeinated alcoholic beverages. For example, Monster Energy launched a line of alcoholic drinks under the name "The Beast Unleashed," which contains alcohol but no caffeine or sugar. This clear separation is a direct response to the regulatory climate and health concerns surrounding CABs.
The Dangers of DIY Mixing Alcohol and Energy Drinks
Just because pre-mixed CABs are off the shelves doesn't mean the risk has disappeared. Many consumers still create their own caffeinated alcoholic cocktails by mixing energy drinks with hard liquor (e.g., vodka and Red Bull). The same health risks associated with the original CABs apply to these homemade concoctions. Consuming a stimulant while drinking alcohol can still make a person less aware of their intoxication and lead to overconsumption. The CDC and other health organizations continue to warn against this practice.
An Accidental Mix-Up: The Celsius Recall
In 2025, an incident highlighted the importance of clear separation between product lines. Due to a production error, some cans of Celsius energy drinks were accidentally filled with vodka seltzer from a sister brand, High Noon. This led to a voluntary recall and underscored the potential for cross-contamination when facilities produce both alcoholic and non-alcoholic beverages. This was an accidental error, not an intentional product feature, and a clear distinction from the previously available CABs.
Comparison of Past and Present “Alcoholic Energy” Drinks
| Feature | Original Caffeinated Alcoholic Beverages (e.g., pre-2010 Four Loko) | Modern Alcoholic Products (e.g., The Beast Unleashed) |
|---|---|---|
| Key Ingredients | Alcohol, added caffeine, taurine, guarana | Alcohol (malt or spirit-based), flavorings |
| Caffeine | Present in high doses | None added |
| Availability | Banned in the US since 2010 | Widely available where legal to sell alcohol |
| Health Risk | High, due to caffeine masking alcohol's effects | Standard risks associated with alcohol consumption |
| Intended Purpose | A "party in a can," designed to both energize and intoxicate | A hard seltzer or flavored malt beverage alternative |
| Regulation | Regulated as an "unsafe food additive" by the FDA | Regulated as standard alcoholic beverages |
Conclusion: The Final Word on Caffeinated Alcoholic Energy Drinks
To summarize, no commercially sold energy drink in the United States has alcohol added to it in a combined, premixed format. The FDA banned this class of beverages—known as caffeinated alcoholic beverages (CABs)—in 2010, and most manufacturers voluntarily complied. While some energy drink companies have since launched new product lines that contain alcohol, these do not contain caffeine, keeping them separate from the energy drink market. The only way to consume an alcoholic energy drink today is to mix one yourself, a dangerous practice that health experts strongly advise against.

List of Health Risks
- Masking of Intoxication: Caffeine can hide the signs of alcohol intoxication, causing people to consume more alcohol than they normally would.
- Increased Risk of Injury: The combination of stimulant and depressant effects can lead to poor judgment, increasing the likelihood of accidents and injuries.
- Cardiovascular Strain: Both caffeine and alcohol affect the cardiovascular system, and combining them can lead to an increased heart rate, palpitations, and blood pressure issues.
- Alcohol Poisoning: The reduced perception of drunkenness increases the risk of drinking a fatal dose of alcohol.
- Dehydration: Both caffeine and alcohol are diuretics, and their combined effect can lead to severe dehydration.
- Sleep Disruption: The stimulating effects of caffeine can disrupt normal sleep patterns, even when a person is tired from alcohol consumption.
The Final Word
In conclusion, the era of premixed, caffeinated alcoholic energy drinks is over in the United States due to federal regulation. Any confusion today stems from the emergence of new, caffeine-free alcoholic product lines from energy drink brands, or from the continued dangerous practice of mixing the two types of drinks at home. The most important takeaway is to understand the inherent danger of combining these two substances, whether intentionally or accidentally, and to make safer, more informed choices.
