What makes peppers so hot?

The substance in peppers that makes them spicy is called capsaicin. It is concentrated in the veins of the fruit (not the seeds) and stimulates the nerve endings in your mouth, fooling your brain into thinking you're in pain. The brain responds by releasing substances called endorphins, which are similar in structure to morphine. A mild euphoria results, and hot peppers can be mildly addictive because of this hot pepper "high".
