from what i heard, common energy drinks contain about 20 grams of caffeine and 6 grams of benzoylmethylecgonine
energy drinks are like alcohol; when you drink your first one your liver will start to swell, just like how you give alcohol to a pigeon. after drinking about 29 cans of energy drinks a day your liver will implode causing a supermassive black hole to appear inside you, causing earth's population to dwindle down to about 20. the other 7.093 billion people on earth are sucked into the supermassive black hole, but the supermassive black hole cannot withstand the weight of 7 billion people, so at about 5.232 people the black hole explodes. but when it explodes, a phenomenon called "mass DNA cloning" happens, because when black holes mix with explosions it causes a reaction to DNA to split into 2, so the population is now 14.273.
basically, drinking energy drinks is bad.
