Why does pepper make us sneeze? ALSO, is it bad if someone snorts pepper, cause my friend did that for a dare during physics class today.

Sneezing is an involuntary reflex to try and get irritants out of our nose and pepper contains a chemical, piperine, that irritates the mucus membrane of the nose by activating your pain and acidity receptors. So, once it’s in there, your body will totally freak and try to get it out of there…with sneezes…lots of sneezes. As for how safe it is…it’s never good to intentionally irritate your mucus membranes, but as long as it doesn’t become a habit (and I can’t see why it should) your friend should be fine.
