  • Energy drinks are far more accessible (and harmful) to children than healthy foods and necessary prescription medication.
    • Ex: if a child is unable to get a needed medicine, (such as a weight-loss drug as mentioned in the article), then it can bar them from having a healthy lifestyle which could increase the likelihood of turning to more self-detrimental options (like chugging energy drinks and scarfing down junk food).
