Pepper balls are a type of ammunition that is used in pepper ball guns. These guns are designed to fire balls that release a cloud of pepper spray when they come into contact with a target. Pepper balls are considered to be non-lethal weapons, and as such, there are specific regulations governing their use and possession.

In most jurisdictions, civilians are not allowed to carry pepper ball guns. However, they may be able to possess them if they have a valid reason for doing so, such as using them for self-defense.
