Pepper balls are not legal in California for civilian use. Penal Code 22810 bans any tear gas weapon that expels a projectile or delivers tear gas by any method other than an aerosol spray, which places pepper ball launchers and their capsaicin-filled rounds outside what civilians may buy, own, or carry in the state.1California Legislative Information. California Penal Code 22810 Aerosol pepper spray is the only tear gas product the law allows the general public to carry.
Why the Launcher Itself Is Illegal
California treats pepper-based chemical irritants as tear gas, and it regulates the devices that deploy them as tear gas weapons. The statute permits civilian self-defense use, but only through an aerosol canister. Any device that fires a projectile containing tear gas falls on the prohibited side of the line, no matter how it is marketed elsewhere.1California Legislative Information. California Penal Code 22810
The Bureau of Security and Investigative Services has said the classification of projectile tear gas weapons takes a case-by-case analysis, but the controlling question is simply whether the device expels a projectile containing a tear gas agent. If it does, civilians cannot possess it.2Bureau of Security and Investigative Services. Clarification Regarding Tear Gas and Other Deadly Weapons Peace officers and certain licensed security personnel are exempt, which is why these launchers appear in law enforcement catalogs but not in retail self-defense aisles.
What You Can Legally Carry Instead
A California civilian can carry an aerosol pepper spray canister of 2.5 ounces or less. The product must deliver its contents as an aerosol, and every canister sold in the state must include a printed warning that non-defensive use is a crime, along with an expiration date and use instructions.1California Legislative Information. California Penal Code 22810
Some manufacturers sell California-specific launcher kits loaded with inert water-filled or rubber rounds. Those projectiles contain no chemical irritant and sidestep the tear gas statute, but a launcher that can also chamber live pepper rounds may still create legal exposure. Treat any device capable of firing a live pepper projectile as prohibited.
Who Cannot Possess Even Aerosol Pepper Spray
Penal Code 22810 keeps the legal aerosol product out of several hands:
- Anyone convicted of a felony or any assault offense, under California, federal, or any other jurisdiction’s laws.
- Anyone previously convicted of misusing tear gas under the same statute.
- Anyone addicted to narcotic drugs.
- Anyone under 18. A minor who is at least 16 may possess pepper spray with written parental consent or when accompanied by a parent or guardian.
Sellers cannot furnish tear gas to any minor.1California Legislative Information. California Penal Code 22810
Penalties for Possession or Misuse
Using tear gas for anything other than self-defense is a wobbler in California. Prosecutors can file it as a felony, punishable by 16 months, two years, or three years in state prison, or as a misdemeanor carrying up to one year in county jail, a fine up to $1,000, or both.1California Legislative Information. California Penal Code 22810
Penalties rise when the victim is a peace officer acting in an official capacity and the person using the tear gas knew or should have known that. In those cases the sentence is 16 months, two years, or three years in state prison, a $1,000 fine, or both, regardless of whether the charge is a felony or misdemeanor.
Possessing a banned pepper ball launcher can also bring separate charges for unlawful possession of a prohibited tear gas weapon. Anyone injured by improper use may sue for civil damages, and a parent or guardian who authorized a minor’s possession can be held jointly liable.3California Legislative Information.

The Pending Federal Challenge
A federal lawsuit filed in San Diego, brought by Byrna Technologies and other plaintiffs, challenges the ban under the Second Amendment. The complaint argues that pepper projectile launchers are in common use nationally, citing more than 750,000 units sold, and that prohibiting a non-lethal self-defense option while allowing lethal firearms is constitutionally inconsistent. The plaintiffs argue the devices are not dangerous or unusual under Supreme Court precedent.
As of early 2026, the case is still in litigation. Until a court rules otherwise, the ban stands and civilian possession of a pepper ball launcher in California remains illegal.
Shipping and Travel Boundaries
Buying a pepper ball launcher online for shipment to a California address does not get around the statute; the buyer can face criminal liability regardless of what the seller advertises. For the legal aerosol product, the TSA bars pepper spray from carry-on luggage and allows one container of up to 4 fluid ounces in checked baggage if it has a safety mechanism, with sprays containing more than 2 percent tear gas by mass banned from checked bags entirely.4Transportation Security Administration. Pepper Spray Amtrak bans tear gas from both carry-on and checked baggage without an exception for small self-defense sprays.5Amtrak. Items Prohibited in Baggage Onboard the Train
If you want a lawful self-defense spray in California, use a standard aerosol canister of 2.5 ounces or less, and only in response to an immediate physical threat. The pepper ball launcher stays off the table until a court or the legislature says otherwise.
