An American man has been left in hospital after eating the world's hottest chilli pepper during a contest in New York State.
A man has suffered two days of thunderclap headaches after eating the world's hottest pepper in a chilli-eating contest. Guinness says it averages around 1.6 million Scoville Heat Units. By comparison a Jalapeño pepper scores 2,500-5,000, while a Scotch Bonnet pepper is 100,000-400,000.
His symptoms started immediately after he had eaten the chilli, with dry heaves.

Sympathetic tone refers to the activation of the sympathetic nervous system, which also results in the constriction of blood vessels.
Capsaicin, the active ingredient in chili peppers, can trigger the frightening condition.
