    Study: Alcohol, Energy Drinks Are Risky Combo

    Researchers Say Drinkers of Alcohol and Energy Drinks Are Impulsive, Even if They Don’t Realize It

    April 15, 2011 -- Drinking alcohol and energy drinks together has become trendy, but it can also be risky, a study suggests.

    The combination makes drinkers feel more stimulated than alcohol alone. However, it has no effect on the impulsivity and lack of inhibitions that come with drinking, says study researcher Cecile Marczinski, PhD, an assistant professor of psychology at Northern Kentucky University.

    ''Even alcohol alone will make you feel stimulated and happy," she says. "Mixing in the energy drink makes that more pronounced. Energy drinks have tons of caffeine in them, more than mixing a soft drink in alcohol.''

    As a result, those who drink alcohol and energy drinks in combination can be highly stimulated and highly impulsive, but feel like they are less impaired, Marczinski tells WebMD. So they are likely to have poor judgment of what they are capable of doing.

    The study is published online in the journal Alcoholism: Clinical & Experimental Research.

    In the past few years, young drinkers in particular have been drawn to mixing alcohol with energy drinks, Marczinski tells WebMD.

    Despite the trend, she says, very little laboratory research has examined the effects of the combination.

    Research has shown the dangers of adding caffeine to alcoholic drinks and marketing them. In November 2010, the FDA warned companies that the caffeine added to some of their alcoholic beverages makes the products unsafe. As a result, some products were removed from the market. Other companies agreed not to make the beverages in the future. Energy drinks also have caffeine, as well as other ingredients such as plant-based stimulants, sugars, and herbs.

    Combining Alcohol With Energy Drinks

    In the study, Marczinski and her colleagues assigned 56 college students, average age 24, to one of four groups. One group drank alcohol and an energy drink. Another drank alcohol alone. A third group had the energy drink alone. A fourth group drank a placebo beverage.

    The researchers gave all participants a behavioral test. For those in the alcohol groups, the researchers waited until the blood alcohol level reached the legal limit to give the test. "We tested their behavior on a computer task that measured their impulsivity," she says.
