Pepper Spray Laws – Washington State

Pepper spray is an excellent self-defense tool and one of the only ranged, less lethal tools available for civilians.

Although pepper spray is legal pretty much everywhere in the United States, laws and regulations do vary from state-to-state, and understanding the legalities concerning the ownership and carry of pepper spray as well as under what conditions you are allowed to deploy it is an important part of your personal self defense plan.

Washington is a state where you definitely won’t have any issues obtaining pepper spray, though there are a few more regulations than in other states when it comes to the age of the purchaser, as well as specific language concerning the contents of the canister.

We will tell you everything you need to know about pepper spray ownership and use in Washington State, and provide you with the most relevant statutes that you should familiarize yourself with.

Fast Facts

  • Several varieties of “defense” spray are legal in Washington state, including conventional OC (pepper) blends, as well as CN and CS (tear gas) blends.
  • There is no restriction on the capacity for civilian carry of pepper and other self-defense spray in the state.
  • One must be 18 years old to purchase pepper spray in Washington State, though exceptions exist for people aged 14 years and older so long as they have their parents’ permission.


Washington State is definitely friendly when it comes to the civilian carry and use of pepper spray and other self-defense sprays and all their varieties.

You have to be of the appropriate age to buy it, though; starting at age 14 one may buy pepper spray so long as they have their parents’ permission, but at 18 years of age it can be bought over-the-counter with no other concessions.

Pepper spray can be carried pretty much anywhere in the state though, as always, you may not carry it onto an aircraft, or into the secured terminal of any airport.

Use of pepper spray and self-defense is also surprisingly clear in the state of Washington considering how flimsy the rest of their self-defense laws are.

Generally, the state makes allowances that one may use force appropriate to the task to protect yourself or someone else who’s about to be injured, and even specifically names malicious trespass or malicious interference with personal property lawfully in someone’s possession as a viable reason, though it cautions that more force than is necessary may not be used and later specifically defines the word “necessary” to mean that no reasonably effective alternative to the use of whatever force was applied appeared to exist to the defendant.

Also take care that the Washington State statutes explicitly state that the amount of force used in defense must be reasonable to affect the lawful purpose of that force.

What does that mean? It means that since pepper spray is still considered a use of force (it is not a harmless prank after all) there should be some significant threat against you or someone else before you use it, though not necessarily a lethal threat.

The inverse is also true: you should not spray someone who simply insults you, yells at you or flips you off.

This should be taken to mean that any threat of physical violence, to include assault or sincere threats of violence could definitely warrant you pepper spraying someone.

It should go without saying that any lethal or potentially lethal threat warrants the defensive application of pepper spray, and that furthermore a great disparity of force exists between the use of pepper spray on the part of the defendant and the use of lethal force by an assailant.


Washington State has entirely reasonable laws governing the purchase, carry and use of pepper spray and other defensive sprays by civilians. Even young people can own and carry pepper spray in the state and take it with them virtually everywhere.

So long as you do not carelessly employ your pepper spray and save it for situations when you really think your safety or life might be on the line you won’t have any issues.
