That vodka Red Bull you’re knocking back might be worse for you than you thought.

A new study published in the journal Alcoholism: Clinical & Experimental Research says consuming alcoholic beverages mixed with energy drinks could increase the urge to drink.

In the double-blind study, participants aged 18 to 30 years old were given either 60 ml of vodka and Red Bull or 60 ml of vodka and soda water.

Both were then mixed with 200 ml of a fruit drink. Participants responded to an “Alcohol Urge Questionnaire” before, and 20 minutes after, consuming the beverage.

The researchers graphed their results. Participants drinking alcohol mixed with an energy drink had a greater urge to drink than those who consumed alcohol alone.

It’s important to note the study was rather small, with only 80 participants aged 18 to 30 years old. Still, the study possibly sheds some light on the effects of mixing alcohol and energy drinks.

The researchers say further studies are needed to determine why vodka Red Bulls made the participants want more vodka Red Bulls.

They also noted an increased urge to drink doesn’t necessarily mean participants would consume more alcohol. Further research would be needed to determine this outcome.
