Four Loko, an energy beer containing as much alcohol as four to six beers and as much caffeine as six cups of coffee, has been linked to several college student deaths. The drink was pulled from store shelves and leftover caffeinated Four Loko was repurposed into fuel by MXI Environmental Services. Hundreds of trucks containing thousands of Four Loko cans arrived at facilities where their contents were transformed into ethanol, which could be used to power cars.

Four Loko's high alcohol content
Four Loko is a line of alcoholic beverages sold by Phusion Projects of Chicago, Illinois, United States. It was first introduced in 2005 as an energy beer and was marketed as a "premium malt beverage" in cherry and berry flavors. The drink contained taurine, guarana, caffeine, and wormwood, which is the supposed psychoactive ingredient of absinthe.
The Four Loko recipe that sent the brand's popularity skyrocketing is also the one that was ultimately banned by the government. Each 24-ounce can contained as much alcohol as four to six 12-ounce beers, and as much caffeine as there is in six cups of coffee. This high alcohol content meant that consuming just one can of Four Loko on a single occasion constituted binge drinking and was therefore deemed unsafe.
In 2010, Four Loko removed caffeine, guarana, and taurine from the drink. However, in 2015, 17 State Attorneys General requested that the alcohol content of Four Loko be reduced. Phusion Projects ignored this request and instead introduced four new flavors with even higher alcohol content (14% ABV), equivalent to 5.5 standard drinks. This increase in alcohol content can result in markedly higher BAC levels for consumers, especially young people.
In 2011, Four Loko was introduced in 12-ounce glass bottles that came in packs of six and had 8% ABV, as well as 16-ounce cans in four-packs with 8% ABV. The alcohol content of Four Loko products has continued to vary depending on state regulations, with cans ranging from 6% to 14% ABV.

Four Loko's caffeine content
Four Loko was initially launched in 2005 as an "energy beer" or caffeinated alcoholic drink. The original recipe included caffeine, taurine, guarana, and wormwood—the supposed psychoactive ingredient of absinthe. A 23.5 oz can of the original Four Loko contained 156 mg of caffeine, which is comparable to the caffeine content in a small or tall (8 oz cup) of Starbucks coffee (160 mg). This amount of caffeine is also twice that of a can of Red Bull (76 mg), although it is important to note that Red Bull comes in smaller cans (8.2 oz).
However, in 2010, the manufacturers of Four Loko voluntarily removed caffeine, taurine, and guarana from the product. This decision was made in response to concerns about the potential health dangers associated with mixing caffeine and alcohol. As a result, modern Four Loko does not contain any caffeine.
It is worth noting that the alcohol content of Four Loko has also changed over time. Initially, a 24-ounce can contained as much alcohol as four to six 12-ounce beers, which is equivalent to an alcohol content of 12% by volume. More recently, Four Loko has been sold in 12 oz bottles with an ABV of 8%.
Despite the removal of caffeine and the reduction in alcohol content, Four Loko remains a popular beverage among college-aged consumers. However, it is important to consume Four Loko responsibly, as any alcoholic beverage has the potential to have dangerous effects when consumed in excess.

Four Loko's popularity with college students
Four Loko, the "blackout in a can", has been a popular beverage among college students since its launch in 2005. Created by three Ohio State University students and Kappa Sigma members, Jeff Wright, Jaisen Freeman, and Christopher Hunter, Four Loko was designed as an "energy beer" with caffeine, guarana, taurine, and wormwood (an active ingredient in absinthe). The original Four Loko cans were 12-ounce cans at 6% ABV, but in 2008, the founders increased the volume to 24-ounce cans and doubled the alcohol content to 12%now-infamous camouflage print packaging, made Four Loko an instant success among college students.
The appeal of Four Loko to college students can be attributed to several factors. Firstly, the combination of alcohol and caffeine provided a unique stimulant effect that enhanced intoxication. Secondly, the large can size and high alcohol content offered a cost-effective way for students to get intoxicated. Thirdly, the lack of marketing and the controversial reputation of the drink created a sense of forbidden fruit, making it appealing to rebellious youth. Finally, the eye-catching camouflage print packaging and low price point of $2.50 per can contributed to its popularity.
Despite its success, Four Loko has faced significant backlash and controversy due to its health risks. In 2010, the brand was mandated to remove caffeine from its formula due to the health risks associated with consuming alcohol and caffeine simultaneously. This formula change sparked protests from devoted fans, with over 100,000 Americans joining Facebook groups opposing the change. Even after the formula change, Four Loko continued to be linked to medical emergencies and hospitalizations, particularly among underage drinkers and college students.
Four Loko's popularity among college students has spread beyond its original market. It is currently available in 49 states in the United States and 21 countries worldwide, including Canada, Mexico, and several countries in Europe and South America. While the brand has endured criticism and formula changes, it remains a staple among college-aged consumers, with its high alcohol content and affordability driving its enduring popularity.

Four Loko's dangerous effects
Four Loko, a popular beverage introduced in 2005, has been the subject of concern due to its potential dangerous effects, particularly among young consumers. The drink, originally containing caffeine, guarana, and taurine, underwent a reformulation in 2010 to remove these ingredients. However, its high alcohol content and attractive flavour profile continue to pose risks, especially when consumed in excess or by underage individuals.
One of the primary concerns with Four Loko is its high alcohol content, which can range from 8% to 14% alcohol by volume (ABV). This is significantly higher than the industry standard of 8% ABV, and the higher alcohol concentrations have been linked to a greater risk of harmful effects on young people. In states like Virginia, Florida, and Montana, where the alcohol content is higher, a significant number of young adults underestimated the alcohol content by one or more drinks, leading to dangerous consequences.
The high alcohol content in Four Loko has been associated with various dangerous effects, including blacking out and vomiting. Additionally, the attractive flavour profile, with options like cherry and berry, sour grape and fruit punch, may appeal to younger consumers, increasing the risk of underage drinking. This is supported by a study that found 93% of respondents who had consumed Four Loko did so while underage.
The combination of high alcohol content and appealing flavours has led to concerns about binge drinking and alcohol poisoning, particularly among college-aged consumers. The drink's popularity among this demographic has resulted in dangerous consequences, with some states and countries taking action to restrict alcohol content or reclassify the beverage.
To address the concerns, some states have implemented restrictions on alcohol content. For example, Canada restricted the alcohol content in each container to 1.5 standard alcoholic drinks following the tragic death of a 14-year-old girl. Additionally, 17 U.S. State Attorneys General requested that the manufacturer reduce the ABV from 12% to 8%, but this request was ignored, and the manufacturer released new flavours with even higher alcohol content.
While Four Loko no longer contains ingredients like caffeine, guarana, or taurine, it is important to emphasize responsible consumption. The potential for dangerous effects remains when the product is not consumed responsibly. Consumers are advised to be aware of the alcohol content and avoid excessive consumption to mitigate the risks associated with this beverage.

Four Loko's transformation into ethanol
Four Loko, the popular beverage launched in 2005, was a caffeinated alcoholic drink that gained a cult-like following, especially among college students. However, its high alcohol content, equivalent to four to six beers, and caffeine levels equivalent to six cups of coffee, led to concerns about the health risks of consuming it. The drink was deemed to cause users to become "'wide-awake drunk'", leading to alcohol poisoning, car accidents, and assaults.
As a result, in 2010, the brand was mandated to change its formula, and eventually, federal authorities banned the sale of the drink, leaving the company with a large volume of unsold product. To address this, Four Loko collaborated with MXI Environmental Services in Abingdon, Virginia, and two other plants to repurpose the leftover drinks into fuel.
MXI Environmental Services, one of three facilities in the US that recycle ethanol, distilled the alcohol from the drinks and sold it to be blended into gasoline. This process not only created a useful product from the leftover drinks but also had environmental benefits, as it prevented the drinks, cans, water, cardboard packaging, and shipping pallets from ending up in landfills or incinerators.
The transformation of Four Loko into ethanol fuel is an interesting example of repurposing a banned substance into a useful product, demonstrating creativity and environmental responsibility in addressing a challenging situation.
