Hemp is legal in Washington. But “legal” doesn’t mean “anything goes.” The rules around growing, selling, and buying hemp have changed a lot in recent years. And honestly, a lot of people are getting caught off guard by those changes.
This guide breaks it all down. Whether you’re a farmer, a seller, or just someone who buys CBD products at the store, this is what you need to know.
What Is Hemp?
Hemp is a plant. It comes from the same family as marijuana. But legally, they are very different things.
Hemp is defined as cannabis that contains no more than 0.3% delta-9 THC by dry weight. THC is the chemical that makes you feel “high.” Hemp has very little of it. That’s the key difference.
Pretty simple, right? Well, it gets more complicated when you look at how Washington state handles hemp products. Stay with me here.
A Quick History of Hemp in Washington
Washington didn’t always allow hemp farming. For years, hemp was grouped with marijuana and treated like an illegal drug.
That changed in 2019. Governor Jay Inslee signed Senate Bill 5276 into law. That bill created a real hemp farming program in Washington. It replaced an old research pilot program and opened the door to commercial hemp production. The Washington State Department of Agriculture, known as the WSDA, took charge of running the program.
Personally, I think this was a smart move. Hemp has a ton of uses. Textiles, food, building materials, CBD products, and more. Washington farmers deserve access to that market.
Basic Hemp Farming Laws
You Need a License to Grow Hemp
You can’t just plant hemp in your backyard and call it a business. You need a license from the WSDA first.
Wondering how to apply? You start at the WSDA’s online application portal. You’ll need to submit a background check along with your application. The background check must be completed within 60 days of your application date. There’s also an annual license fee of $1,200.
Applications for the 2026 growing season are currently open. So if you’re thinking about becoming a hemp farmer, now is a good time to act.
What Information You Must Provide
The application process asks for a lot of details. You’ll need to share your name, contact info, and business address. If you’re a business, you’ll need your business type, license number, and tax ID.
Here’s the part that trips people up. You also need to provide the exact legal description of the land where you plan to grow hemp. That includes GPS coordinates. The WSDA tracks every registered growing location.
The 0.3% THC Rule
This one is critical. Your hemp cannot go over 0.3% delta-9 THC. If it does, it’s no longer considered hemp. It becomes marijuana under state law.
Before you harvest, a WSDA inspector will come out and take a sample. They test a cutting from the top third of the plant. That’s where the highest THC levels are found. You must wait for the inspection before you harvest. If you harvest early, you could lose your license.
What happens if your crop tests too high? You have a few options. You can remove just the flowers and keep the stalks and leaves. You can also create a mixed biomass sample and request a retest. Non-harvested hemp that tests below 0.5% THC may qualify for a retest.
Hemp Products: What’s Legal to Sell in Washington
Okay, pause. Read this carefully. This section has changed a lot in recent years.
The Big Shift: SB 5367
In 2023, Washington passed a law called Senate Bill 5367. It changed how the state defines “cannabis products.” Under this law, any product with a detectable amount of THC is now treated as a cannabis product. That includes hemp-derived products.
What does that mean for you? If a product contains any detectable THC and is meant to be consumed, it can only be sold at a licensed cannabis retailer. Not at a gas station. Not at a grocery store. Not online from a regular shop. Only at licensed dispensaries.
This was a massive change. Before this law, many hemp-derived products were sitting on shelves in convenience stores all over Washington. Delta-8 gummies, hemp-infused drinks, CBD tinctures with trace THC. All of that is now restricted to licensed cannabis stores.
What Products Are Still Allowed at Regular Stores?
Not everything is locked behind a cannabis license. Here’s what can still be sold without one.
Topical CBD products are still fine. Things like lotions, creams, and salves that are applied to the skin. These are called Cannabis Health and Beauty Aids, or CHABAs. They’re exempt from SB 5367 because they’re not meant to be consumed.
Hemp seed products are also still allowed. Things like hemp seed oil, hulled hemp seeds, and hemp protein powder. These don’t contain meaningful THC levels and are recognized by the FDA as food ingredients.
Pure CBD products with zero detectable THC can still be sold at general retail too.
What About Adding CBD to Food and Drinks?
This is where it gets interesting. Right now, neither the FDA nor the WSDA allows CBD to be added to food and beverages as an ingredient. This applies to things like CBD lattes, CBD gummies sold as food products, or CBD as a dietary supplement.
Many people assume CBD in food is fine everywhere. It’s actually not. Not in Washington. Not at the federal level either.
Federal Changes Coming in 2026
Here’s where things get even more important. You need to know this.
In November 2025, the federal government passed a new law as part of a spending bill to reopen after a government shutdown. That law changed the federal definition of hemp.
The new definition restricts hemp to plants with low concentrations of total THC, not just delta-9 THC. This affects products made from other forms of THC, like delta-8, delta-10, and others.
This federal change takes effect on November 12, 2026. Products like delta-8 edibles, delta-10 drinks, and similar items could become very difficult to sell legally once that date arrives.
Think of it like a countdown. Businesses selling those products have less than a year to figure out their next move.
Smokable Hemp: What You Should Know
Smokable hemp is legal in Washington. But smoking in public is not.
You’re not allowed to smoke anything, including hemp, in most public places in Washington. If a police officer sees you smoking something that looks like marijuana, you might get questioned. Officers can’t always tell the difference between hemp and cannabis just by looking at it.
So if you smoke hemp, do it at home. It’s just the smarter call.
Hemp Processor Rules
You don’t need a full producer license to process hemp. But there is a voluntary registration available through the WSDA.
Getting registered as a hemp processor is a good idea. It gives you a certificate that many buyers, banks, and insurance companies require. It can also help when selling into other states or international markets.
If you’re processing hemp into food products, you’ll also need to be licensed through the WSDA’s Food Safety Division. That’s a separate requirement from the hemp processor registration.
Penalties for Breaking Hemp Laws
Let’s talk about consequences. This is the part most people skip, and that’s a mistake.
If you grow hemp without a license, you’re operating illegally. Law enforcement can seize your crop. You can also face criminal charges.
If you sell products with detectable THC without a cannabis license, you’re in violation of SB 5367. The WSLCB has been actively enforcing this. They conduct random audits of grocery stores, convenience stores, and online sellers. Products get seized. Civil penalties get issued.
Hold on, this part is important. Violations under the cannabis licensing system can result in serious consequences for businesses. The WSLCB began stricter enforcement on January 1, 2026. Businesses that don’t comply can face fines, license suspension, or even loss of their license entirely.
It’s less severe than a felony, but still no joke. Even smaller violations can cost you thousands of dollars and damage your business reputation.
Local Rules: Can Cities Ban Hemp?
No. Washington law specifically says that no city or county can ban hemp cultivation or processing within its borders. Local governments cannot create their own hemp prohibition laws.
This is actually a pretty strong protection for farmers and processors. You don’t have to worry about your town suddenly deciding hemp is off-limits.
How to Stay Compliant as a Hemp Farmer
You’re gonna want to get this right from the start. Here’s what you need to do.
Get your WSDA license before you plant anything. Register your land with exact GPS coordinates. Know your THC testing timeline. Don’t harvest before inspection. Keep all your paperwork for at least seven years. The WSDA requires it.
If you’re a seller, check every product you carry. If it has any detectable THC and is meant to be consumed, it should only be sold at a licensed cannabis retailer. When in doubt, contact the WSLCB directly. They have guidance documents and will help answer questions.
A Note on the Rulemaking Process
The WSDA filed new rulemaking in November 2025 to update its hemp regulations in line with federal changes. Those rule updates are still being finalized as of early 2026.
What does that mean for you? Rules may change. The smart move is to check the WSDA hemp program page regularly for updates. You can also sign up for their email alerts to get notified when rules change.
