Know before you carry
Pepper spray laws
in the United States.
Buying it, carrying it, and using it are three different questions. Know the rules for your location and your specific spray before you rely on it.

Check more than the label.
There is no single nationwide checklist that settles every pepper spray purchase or carry decision. The state examples below show how age, eligibility, size, and seller requirements can differ.
- Your eligibility. Check minimum age, rules for minors, and any restrictions tied to convictions or other disqualifying circumstances.
- The exact product. Check the spray’s formulation, dispensing method, labeling, and quantity. Net weight and fluid volume are different measurements, so match the label to the rule.
- Where you will carry. Ask about the rules at schools, campuses, workplaces, courthouses, government buildings, and event venues. State permission alone does not answer a location’s requirements.
- How you will buy it. Confirm seller, delivery, and shipping requirements for your destination. A product being offered online does not establish that you may legally receive or carry it.
02 / Selected state rules
Same purpose. Different restrictions.
These four examples illustrate important differences. They are summaries, not complete statements of each state’s law. If your state is not listed, that does not mean it has no restrictions.
California
Civilian self-defense aerosol sprays are limited to 2.5 ounces net weight. Eligibility restrictions apply, including certain convictions. Separate rules cover minors, so do not assume an adult’s eligibility applies to a teenager.
California POST: tear gas and pepper spray guidanceFlorida
Florida’s self-defense chemical spray definition covers a compact device carried solely for lawful self-defense with no more than 2 ounces of chemical. That definition excludes qualifying sprays from the chemical-device category of concealed weapons. It does not grant permission to carry in every location.
Florida Statutes, section 790.001(4)New Jersey
The personal self-defense exemption covers a person age 18 or older who has not been convicted of a crime, possessing one pocket-sized device containing and releasing no more than 0.75 ounce of a qualifying chemical substance intended to cause temporary discomfort or disability.
New Jersey Statutes, section 2C:39-6(i)New York
The possession exemption requires age 18 or older and excludes people with felony or assault convictions. Sales are through licensed firearms dealers, licensed pharmacists, or other state-authorized vendors. Buyers must provide proof of age and a sworn eligibility statement; no more than two devices may be sold to one buyer at a time. Product standards also apply.
New York Penal Law, section 265.20(a)(14–15)For New York, also review the New York State Courts guidance on spray product and sales regulations.
03 / Before a trip
Crossing a border changes the checklist.
For a road trip, check every state you will enter and the rules at your destination. Do not assume a spray that meets your home state’s rules meets another state’s requirements.
Flying within the United States
The FAA’s passenger exception allows one qualifying self-defense spray per passenger in checked baggage only, no larger than 4 fl oz (118 mL). It must have a positive safety mechanism against accidental discharge. Sprays with more than 2% CS or CN tear gas by mass are prohibited. This tear gas limit is not a general 2% limit on pepper spray’s OC ingredient. See the FAA’s current PackSafe spray requirements.
Check your airline before packing. An airline may prohibit sprays entirely: Southwest prohibits self-defense sprays in both checked and carry-on baggage.
International travel
The FAA notes that international aviation rules prohibit self-defense sprays in both checked and carry-on baggage. Destination possession and import rules are separate. Do not pack a spray for international travel based on the U.S. domestic exception.
04 / Carry responsibly
Ownership is not permission to use force.
Use-of-force rules depend on the jurisdiction and circumstances. For example, New York’s spray exemption permits use only where its justification law allows physical force; California’s civilian rule limits use to self-defense. Follow the official state sources above and get legal advice for a specific situation.
Read the manufacturer’s instructions, keep the safety mechanism engaged while carrying, and store the device away from children. A spray is one part of preparation, alongside awareness, avoiding danger, and knowing how to contact emergency services.
Make a more informed choice.
Confirm the rules first, then choose a safety tool that fits your routine.
