Fourteen Japanese secondary school students were taken to hospital after eating "super spicy" crisps, according to local media.
More than 30 pupils at a Tokyo secondary school were reportedly sharing the crisps during breaktime when some started complaining of nausea and acute pain around their mouths.
Fourteen of them were rushed to hospital. They were all conscious but at least one was feeling so ill they had to be transported on a wheelchair, Fuji TV said.
The broadcaster said a male student brought the crisps to the school "just for fun" because he had eaten them before and found them "super spicy".
The crisps concerned have the brand name "R 18+ Curry Chips", media outlets including Asahi Shimbun and Fuji TV said.
According to the manufacturer's website, under-18s are "banned" from eating the crisps, which are "so spicy that they might cause you pain".
A hefty amount of extremely hot pepper known as "ghost pepper" is used as ingredients, the firm says on its website.
Those with high blood pressure and weak stomachs "are absolutely prohibited" from taking bites, and those who are "timid and have no guts" are also discouraged, the manufacturer's website warns.
Tokyo emergency services, the school and the crisp-maker were not immediately available for comment when contacted by AFP.
