Energy drinks contain caffeine, sugar, and calories in much higher quantities than any other typical food or drink. That’s why it is best to limit them for children and adolescents only. Doctors recommend that children should consume energy drinks sparingly, if at all — and make sure they stay hydrated by drinking water the rest of the time. Plus, there’s evidence that kids who enjoy too many stimulants like these often begin to prefer fake highs because drug withdrawal usually feels like an ill-defined case of lethargy and boredom (or brain fog). It can also lead to substance abuse problems down the road; studies show that over 60% of gateway cases involve drugs such as marijuana, gateway drugs such as cigarettes.
