Pepper spray is legal in Arkansas for self-defense, but only if your container holds 300 milliliters (about 10.1 fluid ounces) or less. Arkansas Code § 5-73-124 treats carrying tear gas or pepper spray as a Class A misdemeanor by default and then carves out an exception for self-defense carry within that size limit.1Justia. Arkansas Code 5-73-124 – Tear Gas – Pepper Spray Miss either condition and you lose the protection.
The Two Conditions That Keep You Legal
Two things have to be true at the same time. Your purpose must be self-defense, and the container must stay at or below 300 milliliters.1Justia. Arkansas Code 5-73-124 – Tear Gas – Pepper Spray
The size cap is generous for everyday carry. A typical personal defense canister from a sporting goods store holds between 15 and 60 milliliters, well under the limit. Where the 300-milliliter ceiling actually matters is if you pick up something larger designed for crowd control or commercial use. That is where otherwise unremarkable buyers get caught.
Age, Permits, and Who Can Buy
Arkansas does not set a minimum age for buying or carrying pepper spray. The statute applies to “any person” and says nothing about age. There is no permit, no registration, and no training requirement.
Many retailers still require buyers to be 18 or older. That is store policy, not state law. The statute also does not add restrictions for people with felony records, though someone on probation or parole may be subject to court-imposed conditions that sweep broadly enough to include pepper spray.
What Self-Defense Means Here
The statute allows carry for “self-defense purposes only” without defining the phrase. In practice, that means a genuine defensive reason, not a pretext. Using pepper spray to win an argument, intimidate someone, or pull a prank takes you outside the exception, and at that point you face the Class A misdemeanor for unlawful possession or use. Depending on what you did, separate assault charges can stack on top.
The self-defense requirement reaches your reason for carrying, not just the moment you press the trigger. If you are carrying with the intent to use it offensively, you are already outside the exception.
Penalties If You Step Outside the Exception
Carrying pepper spray outside the legal exception is a Class A misdemeanor, the most serious misdemeanor classification in Arkansas. A conviction carries up to one year in jail and a fine of up to $2,500.2Justia. Arkansas Code 5-4-401 – Sentence3Justia. Arkansas Code 5-4-201 – Fines – Limitations on Amount Those are ceilings. A judge can impose less. But any Class A misdemeanor conviction leaves a criminal record that can follow you into job applications, housing searches, and professional licensing decisions.
You do not have to actually spray anyone to get charged. Simple possession of an oversized canister is enough.
Tear Gas Is Treated the Same
Arkansas law makes no distinction between tear gas and pepper spray. Both fall under § 5-73-124, both qualify for the self-defense exception, both are capped at 300 milliliters, and both carry the same penalty when the exception doesn’t apply.1Justia. Arkansas Code 5-73-124 – Tear Gas – Pepper Spray Products marketed as “self-defense sprays” sometimes use CS or CN (synthetic tear gas) instead of OC (the pepper-based agent). Under Arkansas state law, that choice does not change anything.
Federal Buildings Are a Different Matter
Even if you are carrying legally under state law, federal buildings are off limits. Under 18 U.S.C. § 930, knowingly bringing a dangerous weapon into a federal facility is a federal crime punishable by up to one year in prison. The statute’s definition of “dangerous weapon” is broad enough to cover pepper spray. In a federal courthouse the maximum climbs to two years.4Office of the Law Revision Counsel. 18 USC 930 – Possession of Firearms and Dangerous Weapons in Federal Facilities
Individual facilities also keep their own prohibited-items lists, set by each building’s Facility Security Committee, and pepper spray commonly appears on them.5Homeland Security.

Flying With Pepper Spray
Pepper spray is banned entirely from carry-on bags on U.S. flights. You can pack one container in checked luggage if it holds no more than 4 fluid ounces (118 milliliters) and has a safety mechanism to prevent accidental discharge. Sprays containing more than 2 percent CS or CN tear gas by mass are prohibited even in checked bags.6Transportation Security Administration. Pepper Spray
Most personal defense sprays sold to civilians use OC, so they usually qualify for checked luggage. Check the label before you pack. And confirm the laws where you are landing: what is legal in Arkansas is not automatically legal in another state.
