Health concerns holding back stock Tragically, Monster Beverage Corp (NASDAQ:MNST)'s energy drinks are the alleged cause of several deaths. A lawsuit was filed in October 2012 asserting that consuming two Monster drinks over two days resulted in the wrongful death of a 14-year-old girl in Maryland. Monster says it plans to "vigorously defend" the suit in court, saying the girl suffered from a preexisting heart condition and that no blood test was performed to confirm that the girl died of "caffeine toxicity." Monster Beverage Corp (NASDAQ:MNST) was hit with another lawsuit this June, claiming that the death of a 19-year-old man in California was caused by drinking two Monsters a day for three years straight. A spokesperson for Monster stated: "T he lawsuit admits that Mr. Morris consumed Monster Energy Drinks for years without incident. Simply because Mr. Morris happened to have consumed a Monster Energy Drink or two on the day of his cardiac arrest does not establish any causal connection between the two."
