No you cannot die from eating the Carolina Reaper although it will make your mouth burn and stomach burn and make you feel like you're dying.
Most people who eat a Carolina Reaper hot pepper never eat the entire thing because it's too hot for them to consume.
I managed to eat at least half of the Carolina Reaper pepper and then cut the rest of it up and put it into some stew which I slowly ate as well.
The Carolina Reaper hot pepper is one of the hottest peppers I've tried and I don't plan to buy anymore of them because my stomach was really hurting after eating half of that pepper.
Then I had stomach issues after eating the rest of it in stew but I just could not throw it out but after that I wish I did throw the rest of the Carolina Reaper out.
Even if you did eat the entire Carolina Reaper in one day you're not gonna die from it and will just experience some stomach discomfort.
Although you'll feel like you're dying.
