"The coroner wrote that Mitchell had drowned, likely due to an arrhythmia triggered by the combination of energy drinks and physical exercise. She noted that he had a blood-alcohol content of about 0.1%, slightly over the legal limit for driving."

That's a lot of alcohol. Where I live they'll for sure tear your license and sentence you to up to two years if you're caught behind the wheel at that level of intoxication.

As for so called energy drinks and alcohol, I'd bet taurine is much more important than caffeine.
