What is a requirement for a person to possess a self defense spray device?

To possess a self-defense spray device, one must be eighteen years of age or older. This requirement is in place to ensure that individuals are legally considered adults, capable of understanding the responsibilities and potential consequences of carrying and using such a device. The age requirement aligns with other legal stipulations regarding the possession of weapons or self-defense tools, reflecting a societal consensus on maturity and responsibility.

While some options suggest conditions like needing a law enforcement job or having a permit from the state, these do not pertain to the general public's ability to possess self-defense spray devices. Additionally, the requirement of prior convictions would contradict the purpose of self-defense items, which are intended for protection rather than restriction for those with a criminal record. Thus, being eighteen and older is the fundamental requirement that applies to the general population.
