I grow the stuff. It’s a beautiful plant, and in minute quantities has medicinal uses, but I personally would be disinclined to consume it in anything like the usual quantities people eat. Then, I am not enthusiastic about eating chili either, while being perfectly willing to use a tincture of it as a local application to reduce the pain of shingles. I need my senses of taste and smell, thank you. And yeah, I can certainly see how eating stupid amounts of either might damage the kidneys.
