An advocacy group says energy drinks are so dangerous they shouldn’t be sold to anyone under the age of 18—and they have a study on hand to support them.

According to the study, funded by the Robert Wood Foundation and conducted by the Rudd Center for Food Policy and Obesity at the University of Connecticut, teens went to the hospital 1,500 times for reasons related to energy drinks in 2011. In 2007, teens made 1,145 energy-drink-related visits to the hospital. That’s way too many, energy drink opponents say. They advocate treating such drinks similar to tobacco.

“Something needs to be done to reduce the dangers of these products to children,” says Jennifer Harris, who coauthored the study. “Companies say these products are safe to market and sell to children as young as 12, but the evidence says otherwise.” (USA Today)
