The Less-Lethal Legal Guide
What California law allows, in plain language.
Not everyone wants a firearm for personal protection.
Some individuals seek a defensive option that provides distance and deterrence without introducing lethal force.
Less-lethal tools such as pepper spray, conducted electrical weapons (tasers), and CO₂-powered launchers like those produced by BYRNA Technologies are often considered for this purpose.
Before purchasing or carrying any defensive device in California, understanding the law is essential.
This guide explains:
Chemical irritants in California are regulated under California Penal Code §22810.
Full statute:
Read Penal Code §22810
Key statutory language from §22810 states:
“Notwithstanding any other provision of law, any person may purchase, possess, or use tear gas or any tear gas weapon for the projection or release of tear gas if the tear gas or tear gas weapon is used solely for self-defense purposes…”
However, that allowance includes restrictions.
Under §22810:
✔ The device must be an aerosol spray device
✔ The container must not exceed 2.5 ounces net weight
✔ The user must not be a felon
✔ The user must not be addicted to narcotics
✔ The device must be used solely for self-defense
The statute also specifies:
“No person shall purchase, possess, or use any tear gas weapon that expels a projectile.”
California law distinguishes between:
That distinction matters when evaluating projectile systems such as pepper balls or CS rounds.
Under §22810, civilians may possess tear gas devices designed as aerosol sprays within the statutory size limits.
Tear gas weapons that expel a projectile are prohibited for civilian purchase, possession, or use in California.
This prohibition includes:
When in doubt, consult current statutory language directly.
Oleoresin Capsicum (OC):
• Derived from pepper
• Common in civilian aerosol spray devices
• Generally permitted within size limits
CS (Ortho-chlorobenzylidene malononitrile):
• Synthetic tear gas
• More tightly regulated
• Often associated with law enforcement deployment
California law regulates tear gas broadly, and classification may depend on formulation and delivery method.
Always verify the chemical classification and delivery system before purchase.
Keychain spraysLegal at 18 and up
Full size canisters2.5 oz is the legal ceiling
Animal repellentsExempt from the limit, for animals onlyUnder Penal Code §22810:
✔ Maximum civilian size: 2.5 ounces (net aerosol weight)
✔ Must be labeled properly
✔ Must be used solely for lawful self-defense
There is no requirement for a training certificate for standard consumer aerosol pepper spray within statutory limits.
However:
Misuse can result in assault charges.
The law allows possession, not reckless deployment.
Chemical agent authority for security professionals is regulated by the
California Bureau of Security and Investigative Services.
Security guards must obtain a BSIS Chemical Agent Permit to carry OC spray while on duty for a licensed Private Patrol Operator (PPO).
Important distinctions:
Failure to comply with semi-annual training or permit renewal can result in loss of authority.
Professional authorization and civilian authorization are separate legal frameworks.

Under §22610:
✔ Adults may purchase and possess stun guns or tasers
❌ Felons are prohibited
❌ Misuse is criminal
As with chemical agents:
Legal possession does not equal lawful use in every circumstance.
Deployment must meet lawful self-defense standards.
Bear spray is typically:
Using bear spray against a person may:
Bear spray is not a substitute for compliant personal defense aerosol devices.
California self-defense law applies equally to:
The legal standard remains:
Less-lethal tools do not eliminate legal responsibility.
Less-lethal tools may be appropriate for:
But suitability depends on:
A device without training can create false confidence.
