Megyn Kelly claims pepper spray is "a food product, essentially." Deborah Blum explains why this is highly misleading:
The reason pepper-spray ends up on the Scoville chart is that – you probably guessed this – it’s literally derived from pepper chemistry, the compounds that make habaneros so much more formidable than the comparatively wimpy bells. Those compounds are called capsaicins and – in fact – pepper spray is more formally called Oleoresin Capsicum or OC Spray.
But we’ve taken to calling it pepper spray, I think, because that makes it sound so much more benign than it really is, like something just a grade or so above what we might mix up in a home kitchen.
