Chile Pepper Weapons?

The article above is really something interesting to read. Apparently the military is starting to use a chile pepper as a non-toxic, tear gas like, weapon in order to make terrorists leave hideouts. According to the article, the "Bhut Jolokia" measures up to 1,000,000 Scoville units. This unit of measurement is used to measure how spicy a pepper is. To put it on a scale, the article mentions the jalapeno pepper only measures between 2,500-8,000. So this is a spicy pepper to say the least. The idea is weaponizing the pepper causes people to choke up, making being in the presence of it unbearable.

I love the idea of this being used as a weapon. First off how expensive could making a weapon out of peppers be? Secondly, I'm not a big fan of war to begin with, so the use of non-toxic weapons is a little more settling then merciless killing. It could prove very effective to smoke out terrorists into the open to take them as prisoners, or to clear out a hideout in order for the military to enter it in search of someone. I definitely like the idea of research for more natural ways to thwart terrorism, and think more should be done to find even more ways.
