Well, I finally ground up the dried habaneros today. I was wearing goggles (swim goggles) and covering my nose with a napkin...and here is what happened.
The moment I opened the cofee grinder, the outside of my eyes started burning, and my nose started burning. The other person in the kitchen ran out gasping for air, and I literally had to disinfect the entire kitchen so as to not kill the next person in there.
Anothe problem is that I do not know how I am going to apply the powder without killing everyone else at the dinner table

. I will manage though.
