Well there are some people out there that can't get things hot enough. Ghost peppers will cure that problem fast. Personally I love taking them into National Guard drill and get the "Mine is bigger than yours" guys to try it. They ALL cry like babies. I get a good laugh out of it.
I also make a mean hot pepper shake (Like crushed red pepper) but mine has 5 different types of peppers from bells to scotch bonnets. Then if the batch isn't as hot as the last batch I can increase the heat by adding ghost pepper dust to the mix. It adds heat without adding pepper flavor.
Ghost peppers are very sweet (for a split second) before they get HOTTTTT. They are a better wake up than a cup of coffee.
