(Newser) – An 18-year-old Ohio prom king died just a week before graduation, and as WKYC reports, toxicology results reveal an unlikely culprit in his death: caffeine poisoning. Logan Stiner of LaGrange had apparently ingested caffeine powder and died after suffering an irregular heartbeat and seizures. The top student and star wrestler had gone home for lunch on May 27; his brother later found him on the floor, reports ABC 10.

It's not clear why Stiner took the powder, but his mother later found bags of it in the house. She tells the Chronicle Telegram her son once told her he took some sort of "pre-workout" substance. Caffeine powder, it's worth noting, is extremely potent: While an energy drink or cup of coffee typically contains 260 to 280 milligrams of caffeine, a teaspoon of caffeine powder can contain 1,600 milligrams. Though it's unclear how much of the powder Stiner ingested, the county coroner notes that 50 micrograms of caffeine per milliliter of blood is regarded as a lethal dose; a milliliter of Stiner's blood contained 70 micrograms. (An Arizona mom says energy drinks are to blame for her 16-year-old daughter's death while on vacation.)

Americans are obsessed to the extreme with all kinds of substances, anything you do to the extreme will kill you at the end... it has nothing to do with Caffeine, has to do with people who do not understand where is the limit !

Holy smokers. Well, caffeine, too much, can certainly cause "a panic attack". That may, spiral out of control. "A little caffeine" is far better, than a lot. I make one (1) scoop coffee, it takes about a week, to get used to it. But when you do? "Smooth sailing". Peaceful, bliss. But still, stimulated. I drink it cold, quick, like a shot. With a water rinse. As, "it stains your teeth". Something fierce. So.. Bang Done Rinse.

While caffeine is dangerous in large amounts, it's irresponsible to link preworkout supplements to those large amounts. The strongest preworkout has the same amount of caffeine as 3 cups of coffee. I've never heard of a caffeine powder and I really don't think it exists. Sounds like you anti supplement stooges confuse pure caffeine with a complex supplement to hype some imagined danger. You can OD on many things just as easily as you can OD on caffeine, especially if you're a stupid teenager.
