Effects of mixing alcohol and caffeine
Centers for Disease Control and Prevention (CDC)
Drinks that have both alcohol and caffeine can cause harm. Although caffeine is a substance that makes people feel alert, when used with alcohol, it does not reduce the effects of alcohol on your body. It might make you feel like you have more energy, or you might feel like the alcohol is affecting you less. This could lead you to drink more alcohol and become more impaired, which increases your health risks. The effects of alcohol on your body do not change when it is used with caffeine.
Health risks
Drinking alcohol that is mixed with caffeine can make you drink more, which could make the effects from alcohol stronger. This could lead to alcohol-related health problems, damage to your body, and early death.
Other concerns with mixing alcohol and caffeine include:
• Higher blood pressure.
• Irregular heartbeat.
• Losing more water from your body (dehydration).
People who mix alcohol with energy drinks are more likely to report:
• Binge drinking.
• Unwanted or unprotected sex.
• Injuries, or damage to their body.
• Alcohol-impaired driving.
• Riding with a driver who had been drinking.
Caffeinated alcoholic beverages
Currently, the Food and Drug Administration (FDA) does not allow companies in the United States to sell caffeinated alcoholic drinks because of their health risks.
In the 2000s, caffeinated alcoholic drinks were pre-mixed drinks that combined alcohol, caffeine, and sometimes other substances to make you feel energized (stimulants). However, these drinks usually had more alcohol than a beer.
Caffeinated alcoholic drinks were heavily marketed to youth. The advertisements connected drinking with activities like action sports or risk-taking behaviors.
In November 2010, the FDA found that it was not safe to add caffeine to these alcoholic drinks. These alcoholic drinks no longer met the legal safety standards. 12 Producers of caffeinated alcoholic drinks have since removed caffeine and other stimulants from their products.
Even though companies no longer sell pre-mixed drinks that have caffeine and alcohol in the United States, people still mix alcohol with energy drinks, especially young people. For example, about one in five college students report using alcohol mixed with caffeinated energy drinks in the past year. However, it can be dangerous.
Keep in mind
Alcoholic drinks that are mixed with caffeine at home or by someone else could have similar health risks as the pre-mixed caffeinated alcohol products that were previously sold by companies.
