Although Washington has one of the oldest legal cannabis markets in the U.S., the state takes a strict approach toward hemp-derived intoxicating cannabinoids—including Delta-8 THC.

Even though cannabis is legal, Delta-8 is not permitted for sale in Washington unless it comes from the regulated marijuana supply chain. This guide explains everything you need to know about Delta-8 laws in Washington in 2025, including what’s banned, what’s allowed, and what buyers should avoid.

Is Delta-8 THC Legal in Washington?

Short answer: No — Delta-8 THC is banned in Washington.

In 2021, the Washington State Liquor and Cannabis Board (WSLCB) prohibited the production and sale of hemp-derived Delta-8 THC, Delta-10, THC-O, THCP, HHC, and other chemically converted cannabinoids.

Washington’s rules mean:

❌ Delta-8 cannot be sold in vape shops, CBD stores, online hemp stores, gas stations, or convenience stores.
❌ Hemp processors cannot create Delta-8 from CBD.
❌ Retailers cannot sell hemp-derived intoxicating cannabinoids.

What is allowed?

✔ Delta-8 may be produced and sold only inside Washington’s licensed cannabis market if derived from cannabis, not hemp.
✔ It must go through the same strict testing and tracking (Seed-to-Sale) as other marijuana products.

Bottom line:
Washington bans all hemp-derived Delta-8 but allows regulated cannabis-derived Delta-8 sold only in licensed dispensaries.

Why Did Washington Ban Delta-8?

The WSLCB restricted Delta-8 due to:

• Safety concerns around unregulated hemp conversions
• Lack of standardized testing
• Youth access issues
• Unclear manufacturing processes
• Public health risks
• Products entering stores without oversight

Washington only allows intoxicating cannabinoids inside the regulated cannabis market, where testing, age verification, and product tracking are mandatory.

Can You Buy Delta-8 in Washington?

✔ Legal

• Licensed cannabis dispensaries may sell cannabis-derived Delta-8 products

• These must be tested and regulated like all marijuana products

❌ Not Legal

• Hemp shops
• CBD stores
• Vape shops
• Gas stations
• Online hemp retailers shipping Delta-8 to WA
• Out-of-state shops shipping hemp-derived Delta-8 into WA

Any shop selling these products is doing so illegally.

Is It Legal to Possess Delta-8 in Washington?

Yes — possession is not illegal.

Consumers can legally possess Delta-8, but the product must come from the regulated cannabis system to be compliant.

Possession is legal; sale and production are regulated or prohibited.

Age Restrictions for Delta-8 in WA

Because Delta-8 is treated as a cannabis product:

✔ Delta-8 vapes
✔ Delta-8 concentrates
