Maybe you've heard of the cinnamon challenge, maybe you haven't. It's a YouTube dare that challenges you to swallow a spoonful of cinnamon without any water to aid in it's passage. What happens more often than not is a subject will end up inhaling the cinnamon and in severe cases lungs have collapsed and emphysema has resulted. Unlike other powders, cinnamon dust does not break down in the lungs and just stays there. Everybody may be doing this but you don't need to follow this fad.
