What is the efficacy of bear spray against humans? Leave aside legal issues, this is merely out of curiosity.
I have heard it stated that bear spray is actually less effective against humans, though I do not remember from where. A friend of mine (a squared away CO that has used sprays many, many times) stated that he was told this by some of the engineers of some of the LL firms that he's talked to. On the other hand, he does agree that major capsaicinoids percentage is generally a great correlation of performance (keeping in mind that there are plenty of folks out there that can power through it anyway). So there's a bit of a disconnect here, as I was presented with an argument about how bear spray has great efficacy against humans, as it generally has 1.33% major capsaicinoids to 2%, while many OC sprays have much lower major capsaicinoids percentage; e.g., Fox Labs Five Point Three says they are at at least 0.70%, while both SABRE Red's and Defense Tech's OC spray line tops out at 1.33%. By comparison, SABRE Red's bear spray is at 2%, while UDAP is at 2% capsaicin and related capsaicinoids, (is CRC the same thing as MC?, as UDAP also makes a 3% OC spray).
And yes, I'm aware that no matter how hot, there are random folks that just aren't fazed by it, and others that will power through it.
