THE USEFUL PART
Keep these in your head.
- Adults 21+ may possess cannabis under Washington law.
- Up to 1 ounce of usable cannabis, 7 grams of concentrate, 16 ounces of solid infused product, or 72 ounces of liquid infused product.
- General adult-use home grow is not authorized. Registered medical patients may cultivate within medical rules.
The status, in one screen
Adults 21+ may possess cannabis under Washington law.
What this label does—and does not—mean
Adults 21+ have legal possession under state law; limits, public-use rules, local rules, and retail availability still vary. It does not answer public use, driving, employment, housing, federal property, tribal jurisdiction, or a city's business rules.
Possession and use
Up to 1 ounce of usable cannabis, 7 grams of concentrate, 16 ounces of solid infused product, or 72 ounces of liquid infused product.
- Public consumption can remain prohibited even when possession is legal.
- Never drive, bike in traffic, boat, or operate machinery while impaired.
- Keep products in their original package and outside the passenger area when transporting within the state.
- Local ordinances and property policies can add restrictions without changing statewide status.
Home cultivation
General adult-use home grow is not authorized. Registered medical patients may cultivate within medical rules.
Plant counts are only the first layer. Lease terms, owner permission, visibility, locked-area rules, nuisance law, processing limits, and possession of harvested cannabis can each change the practical answer.
Medical access
Medical and licensed adult-use markets.
A recommendation, registry card, out-of-state card, or diagnosis does not create identical rights everywhere. Confirm patient eligibility, reciprocity, purchase limits, approved forms, renewal rules, and caregiver rights with the official program.
Buying and retail status
Licensed adult-use retail regulated by the Liquor and Cannabis Board.
Use the state regulator's live license lookup where available. A website, delivery claim, hemp label, social-media account, or storefront sign is not proof of a marijuana license.
What you need to buy legally
No recreational card required
There is no state recreational-consumer card application. Adults 21+ may use a valid, unexpired government-issued photo ID at a licensed adult-use retailer where sales are operational.
Authorization and recognition card
How to qualify: Obtain a medical authorization from an eligible practitioner, then visit a medically endorsed retailer to be entered in the state database and receive the recognition card.
Patients 18–20 must be entered in the database and hold a recognition card to purchase. Adults 21+ can use adult-use retail without a card; registry participation provides medical benefits.
At the dispensary: Bring the recognition card and government-issued photo ID to a medically endorsed retailer.
Open the official patient instructions ↗Do not buy a generic “medical card” online
Only the credential, certification, recommendation, or registry process recognized by this state can authorize medical purchasing. Private evaluation services do not replace state approval where approval is required.
Travel, work, housing, and federal edges
- STATE LINESDo not take cannabis across a state border—even between two adult-use states.
- FEDERAL PROPERTYState permission does not control federal buildings, lands, installations, or federal transportation rules.
- WORKLegal possession does not guarantee workplace use or protection from a lawful drug policy.
- HOUSINGSmoking, cultivation, and possession can be restricted by leases, federal housing rules, or property policy.
- TRIBAL LANDTribal law and jurisdiction can differ from the surrounding state; verify with the relevant tribal authority.
Six-month legal direction
Adult home cultivation was proposed ↗
SB 6204 proposed allowing up to six plants for adults. Recreational home grow remains prohibited unless and until legislation is enacted; qualified medical cultivation is separate.
