Monster Energy drinks can be purchased at any convenience store. The question is can drinking too many cost you your life?
The Food and Drug Administration is now investigating several deaths that may be associated with the popular energy drink.
One Maryland woman claims in a lawsuit against Monster Energy makers the drink killed her 14-year-old daughter, who died about 10 months ago after a severe reaction to the drink.
According to the suit filed in California, the woman said her daughter drank two 24-ounce cans within two days before slipping into a coma.
Each can contains 240 milligrams of caffeine.
The woman says one can of Monster Energy drink holds as much caffeine as seven cans of Coca-Cola.
The company denies claims that drinking two cans can cause caffeine toxicity and lead to death.
The Maryland teen suffered from a common heart defect and was under strict restrictions from her doctor.
The FDA is investigating five cases where people died after consuming the energy drink, though the they have yet to establish a direct link in any case.
The Maryland woman says she wants her tragedy to serve as a wakeup call.
Some states have unsuccessfully tried to restrict the sale of energy drinks to minors. Oklahoma has never pursued the legislation.
