Teenagers should be allowed to consume energy drinks because they can help enhance performance and alertness, especially during busy school days or extracurricular activities. Energy drinks can provide a quick boost of energy when needed, which can be beneficial for students who may have a full schedule or need to stay focused during important tasks. Additionally, energy drinks can also be a source of vitamins and minerals that are important for a growing teenager's development. With proper moderation and guidance from parents or guardians, allowing teenagers to consume energy drinks can help them stay motivated and energized throughout their busy days.
