Red Bull and other 'energy' drinks are popular among younger people who often use them so they can stay up late and carry on partying. Previous research has concentrated on the potential cardiovascular risks of consuming large amounts of caffeine but a new study of 795 undergraduate students by researchers at the University at Buffalo's Research Institute on Addictions has found a link between energy drink consumption and risk-taking. 39% of the sample reported consuming at least one energy drink in the previous month. Men (46%) were more likely than women (31%) and Whites (40%) more likely than Blacks (25%) to consume the drinks. Those who drank energy drinks more than six times a month were three times more likely to have smoked cigarettes, abused prescription drugs and been in a serious fight in the year prior to the study. They were twice as likely to drink alcohol, have alcohol-related problems and use marijuana and were more likely to engage in other forms of risk-taking such as unsafe sex, not using a seatbelt, participating in extreme sports or doing something dangerous on a dare.
