I did the old Paqui one chip challenge, and one that used nuts instead of chips and had 5 different spice levels. They're really hot but I can't see it killing someone unless it exasperates a medical condition they already have. Worst it did to me was mess up my digestion a bit. I like really spicy food though, I've never eaten a raw ghost pepper straight up but I've used dry ones plenty of times to make different dishes and while they're hot it's not too bad imo.
