I would normally say this is a parental issue. However, the quirky combinations of vitamin b, caffeine, massive amounts of sugar combined with whatever else is even slightly rumored to boost energy should be, at minimum, slightly regulated for youth.
I am not doing deep-dive research for this comment, but I would speculate that the above drinks are simply not healthy for developing bodies and brains.
I also suspect that the biggest issues are with lack of moderation.
