Cannabis in Washington: Laws, Legal Status, Recreational & Medical Use

Washington was one of the first U.S. states to legalize recreational cannabis, approving adult-use marijuana through Initiative 502 in 2012. The law allows adults aged 21 and older to purchase cannabis from licensed retail stores while establishing a regulated system for cultivation, processing, and distribution. Medical cannabis had already been legalized earlier, and the state later integrated the medical and recreational markets under a unified regulatory framework. Today, Washington has one of the most mature cannabis markets in the United States, with strict regulations governing retail sales, product safety, and possession limits.

Cannabis Legal Status in Washington

Washington’s adult-use and medical rules have different purchase, cultivation and tax provisions. State authorization does not override federal-property rules or another jurisdiction’s laws. Use a licensed retailer and distinguish ordinary cannabis products from medically compliant products.

Recreational Cannabis Laws in Washington

Legal Age Requirements

Adults must be 21 years or older to purchase or possess cannabis in Washington.

Possession Limits

The adult limits in RCW 69.50.360 cover a combination of:

• One ounce of usable cannabis;
• Seven grams of concentrate;
• 16 ounces of infused solid products; and
• 72 ounces of infused liquids, with a separate low-dose packaged-liquid provision.

For liquids packaged in individual units containing no more than 4 mg THC each, the limit is instead 200 mg total THC. This is a purchase/possession allowance, not a recommended dose. Product weight and THC content are different measurements.

Where Cannabis Can Be Purchased

Cannabis must be purchased from state-licensed retail stores regulated by the Washington State Liquor and Cannabis Board.

Public Consumption Laws

Although cannabis is legal, public consumption is prohibited. Use is only permitted in private spaces.

Home Cultivation

Recreational home cultivation is currently illegal in Washington. Only medical cannabis patients may grow cannabis under certain conditions.

Medical Cannabis in Washington

Medical Cannabis Program

Washington legalized medical cannabis in 1998 and later integrated it with the recreational market under the Cannabis Patient Protection Act, which established patient registries, product standards, and medical cannabis consultant programs.

Qualifying Conditions

The Department of Health’s eligibility guidance includes cancer, HIV, multiple sclerosis, epilepsy and other seizure or spasticity disorders, PTSD and traumatic brain injury. It also includes specified treatment-resistant conditions and symptoms. For example, the pain criterion is intractable pain unrelieved by standard treatments and medications, rather than any chronic pain. A qualifying condition must significantly interfere with daily activities and functioning and be clinically assessed.

Patient Registration

A qualifying Washington resident first obtains the state authorization form from an eligible healthcare practitioner. A certified consultant at a medically endorsed store can then enter the patient in the database and issue a recognition card. Database enrollment is optional for adults but necessary for the additional recognition-card benefits; patients under 18 must enroll and have a designated provider. An authorization alone is not the same as a recognition card.

Medical vs Recreational Differences

RCW 69.51A.210 distinguishes these medical allowances:

• Recognition card: Ordinary endorsed-store limits are three ounces of usable cannabis, 21 grams of concentrate, 48 ounces of infused solids and 216 ounces of infused liquids. Six homegrown plants and eight ounces of usable homegrown cannabis are ordinarily permitted.
• Higher cultivation authorization: A practitioner may authorize up to 15 plants and 16 ounces in the domicile, recorded in the database and on the card.
• Authorization without database enrollment: Four plants and six ounces in the domicile are permitted, but retail purchases remain limited to ordinary adult amounts.

These are conditional permissions, not an unrestricted medical supply allowance. Tax benefits also depend on the seller and product, as explained below.

Is CBD Legal in Washington?

CBD legality depends on the product, ingredients and sales channel. Being hemp-derived and below 0.3% THC does not automatically authorize a consumable product for sale in an ordinary shop.

Hemp-Derived CBD

The LCB’s hemp and synthetic THC guidance says unlicensed stores cannot sell products with detectable THC, including hemp-derived THC. Cannabis health and beauty aids and FDA-approved products have specified exceptions. Do not assume a full-spectrum CBD oil, gummy or vape is exempt merely because its THC percentage is low.

Cannabis-Derived CBD

Products regulated as cannabis must go through licensed cannabis retailers. The source plant alone does not determine where a CBD product can be sold: intended use, detectable THC and applicable exceptions also matter. Medical benefits require the relevant authorization and product standards.

CBD Food and Beverage Laws

WSDA states that CBD is not an allowed food ingredient in Washington’s ordinary food market. Hulled hemp seeds, hemp-seed protein powder and hemp-seed oil may be used when other food requirements are met. Those ingredients are different from adding CBD extract. Cannabis edibles sold through the regulated cannabis system follow separate rules.

Buying CBD in Washington

Check product type, batch testing and Washington sales eligibility before ordering. A national seller’s catalog or shipping checkout is not proof that every formulation complies with state law. The following companies offer CBD product lines; compare the specific product against the restrictions above rather than treating every gummy, oil or vape as freely available.

1. CBDfx

CBDfx offers a range of hemp-derived CBD products including gummies, tinctures, capsules, vapes, and topical creams. The company produces both broad-spectrum and full-spectrum CBD formulations.

2. Foria

Foria develops plant-based CBD wellness products that combine hemp-derived CBD with botanical ingredients. The brand focuses on topical oils, wellness supplements, and specialized CBD formulations.

3. Vena CBD

Vena CBD produces a selection of CBD products designed for daily use, including gummies, tinctures, and capsules. Products are available in both full-spectrum and THC-free formulations.

4. Koi CBD

Koi CBD offers a variety of hemp-derived CBD products including tinctures, gummies, topicals, and vape products. The company publishes third-party lab reports for product transparency.

5. Extract Labs

Extract Labs produces hemp-derived CBD products including tinctures, gummies, capsules, and topical creams. The company focuses on small-batch manufacturing and clearly labeled cannabinoid content.

Where to Buy Cannabis in Washington

Licensed Cannabis Dispensaries

Cannabis products may be purchased exclusively from state-licensed retail stores regulated by the Washington State Liquor and Cannabis Board.

• Cannabis flower
• Concentrates
• Edibles
• Pre-rolled joints
• Vape cartridges
• CBD products

Online Ordering and Pickup

A store may accept an online reservation for in-store purchase, but retail home delivery should not be described as merely “limited.” The LCB requires retail sales to be completed on the store’s premises. Separate noncommercial adult transfers and authorized medical designated-provider assistance are not general delivery-business licenses.

Cannabis Taxes

The ordinary cannabis excise tax is 37%, separate from applicable state and local sales taxes. Under RCW 69.50.535, qualifying recognition-card holders purchasing medically compliant, appropriately tested products from medically endorsed retailers receive an excise-tax exemption until June 30, 2029. The card does not exempt every product from excise tax.

Department of Revenue sales-tax guidance is broader: for its recognition-card exemption at endorsed retailers, compliant products include any cannabis product purchased by a qualifying cardholder. It also describes exemptions for specified low-THC and high-CBD sales. Ask the retailer to distinguish the sales-tax exemption from the narrower excise-tax exemption.

Cannabis Penalties and Restrictions

RCW 69.50.4014 makes unauthorized knowing possession of 40 grams or less a misdemeanor, subject to lawful adult and medical allowances. RCW 69.50.4013 generally makes other unauthorized simple possession a gross misdemeanor, with increased maximum jail exposure for qualifying repeat convictions.

Manufacture, unlicensed sale and possession with intent to distribute are separate offenses and may carry felony consequences. Public consumption and impaired driving remain prohibited. Legal possession is not permission to take cannabis across state or national borders.

Recent Legislation and Upcoming Changes

The 2026 home-growing proposal SB 6204 did not become law; its recorded history ends with placement in the Senate Rules “X” file on February 26. Recreational home cultivation remains unauthorized.

SHB 2152, Ryan’s Law, did become law. Beginning January 1, 2027, specified hospitals, nursing homes and hospice care centers must allow medical cannabis for qualifying patients with terminal conditions under facility policies. Smoking and vaping are prohibited, patients or designated providers handle the cannabis, and secure storage is required. Emergency-care settings and other specified exclusions apply; this is not general permission to use cannabis throughout every healthcare facility.

Washington adults can buy through licensed stores, with separate limits for flower, concentrates, solid products and liquids.
