Chili peppers are rated on the Scoville scale, which measures their hotness or piquancy. The jalapeno is rated between 2,500 and 8,000 units, which is why it’s capable of easily stinging an unseasoned chili eater’s mouth. On the other hand, India’s bhut jolokia pepper—found primarily in India’s northeastern states— is rated at a whopping 1,040,000 Scoville units, making it the spiciest chili on Earth.

Bhut jolokia, also known as ‘ghost chili,’ is in fact so spicy that scientists in India have decided to use it to craft the first-ever, nontoxic chili pepper grenade.
R.B. Srivastava, the director of the Life Sciences Department at the New Delhi headquarters of the DRDO (Defense Research and Development Organization) explained the thought-process behind the invention to the Associated Press: “This is definitely going to be an effective non-toxic weapon because its pungent smell can choke terrorists and force them out of their hide-outs.”
