Alcohol Mixed With High-Caffeine Energy Beverages May Increase Desire to Drink

Mixing alcohol with high-caffeine energy beverages may increase a person’s desire to continue drinking alcohol, according to a new study published in Alcoholism: Clinical and Experimental Research.

The study included 26 adults who drank alcohol and energy drinks alone and in combination over six days, Medical Daily reports. After each session, participants rated their desire to drink. In addition, their breath alcohol concentration was measured.

Participants had a greater desire to drink after they consumed alcohol and a high-caffeine energy drink, compared with drinking the same amount of alcohol alone, the study found. The researchers said caffeine may increase the rewarding properties of alcohol.
