Must this Bhut Jolokia (ghost) powder actually be cooked? I've recently purchased this powder after having a small sample of Bhut Jolikia (ghost) powder previously in a miniature powder selection received as a gift (that one didn't come with this warning). This one has this warning on the back of the packet: "Must be cooked before eating".

Is this warning just there to ward off carelessness with this very seriously hot powder? Or would there be an actual reason this powder must be part of some cooking process?
The ingredient list is really short, so I guess it's just dried and ground up Bhut Jolokia peppers. I could imagine that if you were to take this fine powder "raw", it could go into your airways after triggering a cough response because of the intense spiciness. That could lead to respiratory problems. If you dissolve it in e.g. curry or chili, this won't happen.
