Pepper Spray Self Defense: What You Need to Know

Pepper spray is a popular and effective self-defense tool that can help you fend off attackers and escape dangerous situations. However, before you buy or use pepper spray, there are some important things you need to know about its legality, safety, and effectiveness.

What is Pepper Spray?

Pepper spray is a chemical agent that causes intense pain, inflammation, and temporary blindness when sprayed into the eyes, nose, or mouth of an attacker. The active ingredient in pepper spray is oleoresin capsicum (OC), which is derived from chili peppers. OC is not a tear gas, but a natural irritant that affects the nerve endings and mucous membranes of the body.

How Does Pepper Spray Work?

Pepper spray works by creating an inflammatory reaction in the eyes, nose, mouth, and skin of the attacker. This causes:

  • Severe burning sensation and pain

  • Excessive tearing and involuntary closing of the eyes

  • Swelling and redness of the eyelids and face

  • Difficulty breathing and coughing

  • Runny nose and drooling

  • Nausea and vomiting

These effects can last from 15 to 45 minutes, depending on the concentration and amount of pepper spray used, the sensitivity of the attacker, and the environmental conditions. During this time, the attacker is incapacitated and unable to see, breathe, or fight back, giving you a chance to escape and seek help.

How to Use Pepper Spray?

Pepper spray comes in different forms, such as aerosol cans, keychain dispensers, gel, foam, or stream. The most common and effective form is the stream, which shoots a jet of liquid that can reach up to 10 feet. To use pepper spray, you should:

  • Hold the canister in your dominant hand, with your thumb on the trigger and your index finger along the side.

  • Aim for the eyes, nose, or mouth of the attacker, and press the trigger firmly and briefly. Do not spray continuously, as you may run out of pepper spray or cause overexposure to yourself or bystanders.

  • Move away from the attacker as soon as possible, and avoid touching your own face or eyes. If you get pepper spray on your skin or clothes, wash it off with soap and water as soon as possible.

  • Call the police and report the incident. Do not assume that the attacker is incapacitated, as they may recover sooner than expected or have a weapon.

Is Pepper Spray Legal?

Pepper spray is legal in all 50 states, but some states have restrictions on its size, strength, or usage. For example, some states require a license, registration, or training to carry or use pepper spray, while others limit the amount or concentration of pepper spray that you can buy or possess. Before you buy or use pepper spray, you should check the laws and regulations of your state and local area, and follow them accordingly.

What are the Risks and Limitations of Pepper Spray?

Pepper spray is not a foolproof or risk-free self-defense tool. Some of the risks and limitations of pepper spray are:

  • It may not work on some attackers, such as those who are intoxicated, mentally ill, or highly aggressive.

  • It may backfire on you, if the wind blows the spray back to your direction, or if the attacker grabs the canister and uses it against you.

  • It may affect bystanders, pets, or wildlife, if you spray it in a crowded or open area.

  • It may cause serious or permanent injuries, such as eye damage, asthma attacks, or allergic reactions, to yourself or the attacker, especially if used excessively or improperly.

  • It may not be allowed or accessible in some places, such as airports, schools, or public buildings, where security measures or metal detectors may prevent you from carrying or using it.

How to Choose and Store Pepper Spray?

If you decide to buy and use pepper spray, you should choose a product that is:

  • Reliable and reputable, from a well-known and trusted brand that has a proven track record and quality control.

  • Effective and safe, with a concentration of 10% or less of OC, and a Scoville Heat Unit (SHU) rating of 2 million or less. Higher concentrations or SHUs may not be more effective, but may cause more harm or legal issues.

  • Convenient and comfortable, with a size, shape, and design that fits your hand, pocket, purse, or belt, and has a safety mechanism that prevents accidental discharge.

  • Suitable and legal, for your state and local area, and for your intended purpose and situation.

You should also store your pepper spray properly, by:

  • Keeping it away from children, pets, or unauthorized persons, and locking it in a safe or secure place when not in use.

  • Checking the expiration date and testing the spray periodically, and replacing it if it is expired, empty, or defective.

  • Avoiding extreme temperatures or direct sunlight, and storing it in a cool and dry place.


Pepper spray is a powerful and popular self-defense tool that can help you protect yourself and your loved ones from harm. However, pepper spray is not a magic bullet, and it comes with its own risks and responsibilities. You should use pepper spray only as a last resort, and only when you are in imminent danger and have no other option. You should also educate yourself on the laws, safety, and effectiveness of pepper spray, and choose and use it wisely and responsibly. Remember, pepper spray is not a substitute for awareness, prevention, and common sense. Stay safe and stay smart.
