Some students drink 'energy' drinks alongside alcohol to counteract alcohol's depressive effect and to enable them to stay awake, and drink, longer. A U.S. study of 4,271 students from 10 universities found that those who mixed alcohol with energy drinks drank significantly more during a typical drinking session and got drunk twice as often. Even adjusting for the amount of alcohol drunk those who also used energy drinks were twice as likely to be hurt or injured, twice as likely to require medical attention and twice as likely to get into a car with a drunken driver. They were also twice as likely to take advantage of, or be taken advantage by someone sexually. White, male students who played sport were more likely to mix alcohol and energy drinks.
