I know that when I've bought it I didn't fill out forms as with a gun. I just bought a few cans.

Self defense, if true, would work.What is the law concerning having pepper spray in Southern California?
They recommend you take instruction on safety, but you won't need any paperwork or anything. Pretty much same with tazers. just no mace :|
