Can you tell me if monster energy drinks can be deadly for you?

A handful of deaths: have been reported, but in none of the cases so far was it really a slam-dunk kind of proof. It has mostly been in younger people using higher doses (3-4 bottles of 5 hour energy), and many of them had underlying heart disease. Caffeine IS a stimulant, and while not as potent as amphetamine etc., in high doses it does the same things.Other stuff in it likely harmless, but unknown safety really.
