In California, most people may purchase, posses, or use a stun gun, and they do not have to obtain a permit. However, you may not purchase, possess, or use a stun gun if you are a convicted felon, someone convicted of an assault under federal or any state’s laws or the laws of any country, or have a prior conviction for misusing a stun gun under Cal. Pen. Code §244.5, or addicted to any narcotic drug.
