Everyone knows Doritos aren't good for you, but who knew they could make you feel like you were having a near-death experience? Doritos Roulette flavor apparently caused 14-year-old English teen Beth Laybourn to stop breathing, and as a result the snack chips that come with a warning label have been banned in many U.K. schools, according to AOL.

Laybourn, who has a pre-existing respiratory condition that makes her sensitive to spicy foods, said that after eating the chips, she thought she was going to die, reports the Guardian. George Pindar School in Scarborough, North Yorks, sent a letter to parents warning them that the aptly named Doritos Roulette could cause "severe distress."

Launched in April in the U.K. and in the U.S. for a limited time, the premise of Doritos Roulette is that, like the game Russian Roulette, only a few "invisible hot chips" in the bag (around 1 in 6) are "lethal," i.e. so spicy you might need a glass of milk afterwards. The other chips are dusted with the usual Doritos nacho cheese flavor.

"There's a warning on the pack for a reason -- the invisible hot chips are exactly that," said Doritos marketing manager Michael Walford. "They're hotter than most of the spiciest dishes out there so you're going to want to have a glass of milk at the ready in case you get one."

A glass of milk and Doritos? Not so appetizing.

 The hotness of peppers is measured in Scoville Heat units, and Doritos Roulette doesn't play: the hottest pepper, a Scotch Bonnet, is around 100,000–350,000 in Scoville Heat units, and the invisible spicy Roulette chips are 78,000 Scoville Heat units, according to the Independent U.K. Jalapenos range from 2,500 - 10,000.

But this is from the Frito-Lay snack company that brought you "3rd Degree Burn" flavored Doritos. You have been warned.
