I am asking this for my high school project about energy drinks.
None of them. Energy drinks are no more unhealthy than your average soda. Caffeine helps increase alertness and it would take several GALLONS of coffee to kill someone from too much caffeine.
The most caffeinated drinks though are NOS (http://www.caffeineguru.com/reviews/NOS/) and Cocaine (the energy drink, not the drug)



my opinion, all of them are bad. they increase your heart rate, and blood pressure, and can cause medical problems in the long run.
