However, many parents may not realize that by stocking the fridge with drinks high in caffeine, they’re helping their kids get buzzed. According to a press release issued by Elsevier Health Sciences, adolescents are the fastest growing population of caffeine users. Researchers from Brescia University College conducted a study to determine why. Caffeine is the most accessible and widely used ed psychoactive drug in the world. It is also the only legally and socially acceptable drug for teens to consume.
