Regarding this column: Can you develop resistance to pepper spray by eating spicy food?

Perhaps Irma has a vigorously defensive mucous membrane system (or poor nerves in that area) and therefore is able to derive more joy from eating spicy foods, purely because she receives less of the “heat” associated with them.
And perhaps this same mucous membrane system she has also defends her against the hot effects of the pepper spray.
I’m suggesting that her natural defenses may contribute to both her love of spicy foods, and resistance to pepper spray.
I’ve also found that one’s level of “resistance” to the spiciness of peppers might be limited to one type of pepper. I’ve seen people who can eat habaneros like mad, but expose them to a vietnamese pepper and they lay writhing on the floor. On the other hand, a person who frequents restaurants like Pho 88, and can gobble those peppers, react to strong Indian spices.
Cecil mentions the “chemical compound capsaicin and some of its close relatives,” I am assuming that the relative’s heat feels different to you when you expose your mucous membranes to them.
Also, some people do accidentally expose their eyes to the stuff. I remember a particular trip to Pho 88 … a guy named Bill with us loves the hot stuff. He was dissatisfied with the red sauce they gave us, it only had a little spice. They brought us a yellow mustard sauce after that which he said had a bit of kick. Then they brought out some orange stuff with seeds in it - that sauce curled my nose hairs.
Anyhow, he loved it and ate a ton of it, despite the fact that it made his nose and eyes run as he ate it.
When we got back into the truck after lunch, he wiped his running eyes with his fingertips. Unfortunately, he must have had some of the sauce on one of his fingers, because he started screaming and trying to claw his eye out. We were on the road already, and couldn’t do anything for the poor guy. It took about 20 minutes before his eye stopped burning. And that was just a mild touch, in one eye, by a pepper served in a restaurant (albeit a hot pepper).
Imagine a full dose, in both eyes, of a concentrated solution. I can also imagine if they use more than just capsaicin, and combined some of its close relatives, that it would feel worse.
One more question here - is it true that you can build up a resistance to pepper spray by being blasted with it repeatedly? I’m sure Irma can answer that question for us (as it appears to happen in her training). I saw a movie once where a guy was blasted in the face with pepper spray and he shrugged it off, and said you can build up a tolerance to the stuff.
I can definitely raise my resistance to pepper in the mouth by eating a lot of it, but do your eyes and nose adjust the same way?
