Caffeine — the seemingly benign stimulant found in coffee, energy drinks, soda and even chocolate — has been implicated in the death of a 23-year-old British man, who reportedly overdosed on caffeine powder he purchased on the Internet.

America’s favorite drug has gotten a lot of bad press lately.

In October, a spate of alcohol-poisoning cases on U.S. college campuses were attributed to caffeinated malt liquor drinks, most notably an incident at Central Washington University in which 10 students were rushed to the hospital after indulging in too many fruit-flavored Four Loko drinks.

Last week, according to AOL Health, it came to light that Michael Lee Bedford, the British man, died after consuming “spoonfuls” of caffeine powder at a party with friends. AOL Health reports that Bedford had the equivalent of 70 energy drinks in his system at the time of his death in April. According to Dr. Eric Braverman, a lethal dose of caffeine would be about 10,000 milligrams — or 100 cups of coffee — the website reports.
