I grow them and eat them. Other people also grow different ones for me. I got hooked on hot peppers when I was around 12 years old in new mexico. A welder friend of my dad made a very hot chili in his shop, because his wife would not let him make it in the house, from then on hot food was my favorite. It got to the point that I don't like food unless it is hot. I have never had digestive problems from peppers. The hottest pepper I have ever grown and eaten is the red habenero. I collect pepper extract sauces, but they are definitely not fo the timid. The best thing to cool the effect of peppers is alcholic drinks, but I don't drink anymore, so anything acetic helps.
I have heard crazy stories about the bad effects of peppers, but I personally seen by friend eat one of my jalepeno peppers I grew in an area of my garden that were always extraordinaly hot, it caused him to lose his breath and actually caused a couple blisters to form on his lips. Funny, I could never get him to try another pepper of any kind after that.
