I think that Oklahoma outlaws the use of wasp spray for personal defense; I personally don’t care since I carry a .32 Beretta Tomcat with Hydra Shocks.
I’m sure on the spray can there is a sentence or two that the product is only to be used as intended. It’s not meant to spray into someones eyes or face. I get the self-defense thing and doing what you can when put into a situation but the product is not intended for self-defense. Just my two cents.
