If you’ve been to a bar any time in the past 15 years or so, then odds are you’ve either had a Red Bull and vodka or at least are familiar with its effects. Legend has it that mixing the caffeine and alcohol is supposed to make you get buzzed quicker, but according to a new study, that’s not necessarily the case.

According to Science Daily, a study published in the Journal of Consumer Psychology says that the combination of the two might not be that potent after all.

The study was conducted with 154 men of various ages and backgrounds, and they were all told they would be consuming a cocktail made up of vodka, energy drink and fruit juice. All of the drinks were made the same, with the only exception being the way they were labeled: Red Bull and vodka, vodka cocktail, or fruit juice. While all of the participants drank the same concoction, those who believed they were drinking Red Bull and vodka showed the most signs of inebriation, confidence and risk-taking. In the scientific community, they call that the placebo effect.

Why people want to be chugging energy drinks at night never made sense to us anyway, but at least now there’s a scientific reason to back it up.
