Question

You could fill a store with all the energy drinks available. They promise to make people feel more energetic and think more clearly. These products have names like Red Bull, Monster, Ripped Force, Speed Stack and 5-Hour Energy. They appeal mainly to young people.

Professor Chad Reissig, at Johns Hopkins University in Baltimore, is a medical researcher who studies drug dependence. He says the team he works on got interested in studying energy drinks.

He says the researchers have found three things. One: there are hundreds of brands of energy drinks in most major countries. Two: the drinks are not clearly labeled with enough information. And three: the amount of caffeine differs greatly. Some contain as little as fifty milligrams, while others as much as five hundred.

Some people combine energy drinks with alcohol. They think they can drink more alcohol that way and not be affected. Studies, however, suggest that they are still under the influence of the alcohol even if they do not feel that way.

Some makers of energy drinks do provide warnings. For example, a popular energy drink warns against use by people who are under the age of twelve. The directions also advise people to limit caffeine products and to drink only half the bottle.

The team at Johns Hopkins University published a report in the journal Drug and Alcohol Dependence. They suggested that the amount of caffeine and other ingredients be clearly listed on the drink. The researchers are continuing to study energy drinks. They are seeking young people who have had a bad experience after drinking them.
