Ingesting Dry Cinnamon
It's particularly dangerous to try to eat a large amount of dry cinnamon on its own. Teenagers sometimes try this "cinnamon challenge," and it has led to hospitalizations. It can cause choking and lead to collapsed lungs. Ingesting dry cinnamon powder can also cause aspiration pneumonia. More common side effects include burning of the mouth and throat, vomiting, nosebleed, long bouts of coughing and tightness in the chest

So what kind of peppers were those and what was the spice powder?

Habaneros

Cinnamon

As I understand it, hot chilis are't harmful. On the other hand ground cinnamon in that quantity most likely is harmful. It could easily find its way to your lungs. It is bark from a tree.

Please don't do this again. Just sayin' Gracias por leer esto.
