The caffeine content of most Monster Energy drinks is approximately 10 mg/oz (33.81 mg/100ml), or 160 mg for a 16 oz can. The packaging usually contains a warning label advising consumers against drinking more than 48 oz per day (16 oz per day in Australia). The drinks are not recommended for pregnant women or people sensitive to caffeine.
In December 2011, 14-year-old Anais Fournier died of "cardiac arrhythmia due to caffeine toxicity" after drinking two 710 ml (24 US fl oz) cans of Monster Energy drink containing a combined amount of ~475 mg caffeine.
Heck I will not touch the garbage.
